Our Family OHC: Pine Cones and More About Pines

Photo by Mr. A

Our study of pine cones started way back when I was writing the Autumn Series ebook. We gathered a few pine cones to use in the experiments suggested. We had fun soaking the cones in a bucket of water and then setting them in the sun to observe them as they dried and opened up again. Simple things sometimes make the deepest impressions and honestly, none of us had really put all the pieces together until doing the experiments. I know I took photos but they are lost somewhere on my hard drive. Could that be a sign of taking too many photos? I bet a lot of you can relate to my desire to document as much as I can about our world and that leads to lots of images to save and enjoy.

Our unofficial theme as we worked through this study became something like this:
Pine cones don’t just hold still, they are a living thing created for a specific purpose.

What else pushed this pine cone study up another notch?

We have had sort of an on-going study of the female and male cones of the pines in our area.

We studied pine cones back in February of 2008 as part of the Winter Wednesday studies: Cones and a Woodpecker. We also studied pines as part of the Winter Series back in February 2010. This time though we are really trying to concentrate on the cones.

We extended our study of female and male cones.

Male cones with the pollen.

This is the photo that sort of started it all so long ago. We wondered if these were “baby pine cones”. Well, it turns out they are not and only after completing a study of what gymnosperms are in our biology study did things start to fall into place. There are male and female cones on the tree. Females are usually at the top and males at the bottom. The males have the pollen that is wind driven up to meet up with the female cones. How about a simple video that even I can understand? Here you go!

Pine Cones on YouTube.com

Next we wondered why the female cones are sticky and then we guessed it had to do something with capturing the pollen…but that is whole other subject.

This guy wanted to be included in our pine cone study this week. He was so very happy that I put out some extra walnuts for him when I was filling the birdfeeders and he climbed up the tree to look in the living room window at us.

“Thanks a lot”, he said as he swished his big fluffy tail and then dropped to the ground and off to eat some more.

There were also some bird friends that made an appearance but I will save those for another post.

There is always something to learn about in our world and these challenges have helped us focus on things that we never dream of making into a complete study all on their own. I love it.

Autumn 2010 OHC #9 Pine Cone Study

Today we went on a drive up in the mountains and would you believe there was snow! I spotted some freshly fallen pinecones and it was a perfect introduction to this week’s challenge. The snowy landscape reminded me that we will soon be finished with the Autumn Series and it will be time for a new season to start. The Autumn Series of Outdoor Hour Challenges has greatly added to our family’s knowledge of everyday things around us and I hope they have helped your family too. Next week will be our last autumn challenge and a nice giveaway so make sure to pop over to the blog next Friday to read all about it.

Autumn Series #9
Pine Cones
(You may also like to use this challenge: Pine Cones.)

“Their foliage is evergreen but is shed gradually. The pollen-bearing and the seed-producing flowers are separate on the tree. The seeds are winged and are developed in cones.”
Handbook of Nature Study, page 674

Inside Preparation Work:
Read pages 670-675 in the Handbook of Nature Study (Lesson 185). This section talks about the pine tree and gives the background for this challenge. Pay attention to questions 5 and 6 in this lesson covering the pine cone.

Compare A Tree with Cones and A Tree Without Cones

Compare needles and leaves, including their arrangement on the branches, shapes, and colors.
Compare the trunks and bark, including the shape of the tree. Does the main trunk go straight up or branch out? How low do the branches start? Is there a crown?

Outdoor Hour Time:
Take fifteen minutes outdoors this week to explore your yard or neighborhood looking for a pine tree and pine cones. Remember how to identify a pine tree and use some of the things you read about in the Handbook to help your child learn a little about the pine tree. You could point out the difference between an evergreen and a deciduous tree, how the pine tree’s leaves are needles, the distinct shape of a pine tree, and the cones. Collect at least one cone to bring indoors for observations in the follow-up activity.

Follow-Up Activity:
Use a hand lens to look closely at your pine cone. Take note of its shape, size, color, and patterns. The Handbook of Nature Study suggests the following sketches in your nature journal:

Bundle of needles, showing the sheath and its attachment to the twig.
The cone.
The cone scale.
The seed (under the scales)

You can use the notebook page provided with the Autumn ebook, a blank page in your nature journal, or a blank notebook page.

Additional activity: Soak your cone in water. Check your cone every 15 minutes to see what happens. Now let the cone dry. This sometimes will loosen the seeds inside and you can take a closer look at their shapes and structure. Try this activity again and soak only half your cone in water and see what happens. You can try this additional activity: Pine Cone Science Experiment.

Additional Resources:
Help in identifying pines.

A Pine Cone Tale: This link will be helpful if you don’t have access to a pine tree to observe and the formation of cones.

Note: This nature study challenge can be found in the Autumn 2010 ebook.

If you would like to own this ebook, it is part of the Ultimate Naturalist Library for members. You can find more details on how to get your own membership here: Join Us!

Spring Walk: Wildflowers, Ferns, Holes, and Pines

The glories of spring are bursting out all around in our neck of the woods. The other day I mentioned that I could smell the difference in the air as we hiked. Well, today I noticed that I can hear the difference in the seasons….the woods are filled with birds and insect buzzings. The bees and other flying gnat sort of insects were flying in and out of the meadow as we stopped to observe the flowers. What a welcome sound!

Our meadow view is changing each time we hike this way now. The popcorn flowers are still blooming along with some Sierra Shooting Stars and if you look carefully about center of this photo you will notice a big hole that someone is digging. We are stumped over who could have made it.

Speaking of holes, this is one right in the middle of the pathway. It isn’t as large as the other hole, but our dog loves to stick her nose down there and sniff every time we pass by here.

Here is yet another hole we noticed freshly dug on the side of the trail. This one is not as neat and tidy as the other hole and you can see all the broken rocks and dirt that have been excavated out of the hole. I am assuming two different creatures dug these holes since they are made so differently.

Sometimes we wish we could set up a camera to capture the activity after we leave each day. My boys are always so curious about these holes and we have never really seen anything that we think might be actually digging them. We can venture guesses, but if we had a camera rigged up we might confirm our ideas.

The only creatures besides birds that we saw on our hike today were a Gray squirrel and an Alligator lizard and we know neither of those critters made these holes.

Here they are! Sierra Shooting Stars….there are so many of these blooming right now that some areas are just polka-dotted with pink. It must be spring.

We will watch these Mule’s Ears for a long time before they actually bloom with a sunflower shaped flower. Can you guess why they call them Mule’s Ears?

We have been noticing all the new growth on the ferns on the sides of the canyon as we walk down.

Here is the backside of the fern. Isn’t it interesting? We are determined to spend some time this week learning more about ferns.

The Maidenhair ferns are so beautiful right now. Notice the black stems?

This is what a fern looks like as it unfurls its fronds. They are all curled up like this to begin with and then they slowly unroll and flatten out. Fascinating and amazing at the same time!

Wow! The pines along the trail are all popping out with these red growths on the ends of the branches. We are going to research what part of the plant this is…the new needles, the cones, something else? My boys think they are the baby cones. I’m not sure. Time to investigate.

Edit 4/28/10: These are pollen cones. These are the male cones and they contain the pollen to fertilize the seeds which are on the female pine cone. Now we know.

We are not even sure what kind of pine tree this is. Look at the length of those needles!

The only other thing worth mentioning is that our black lab had FIVE ticks on her when we got back to the car. It is definitely tick season and we will start to make appropriate adjustments to our hiking routine, long pants for us and a thorough going over the dog’s fur before we head home each day. If you catch the ticks before they burrow in, you can just flick them off easily. They are actually fairly easy to spot and we rarely have trouble with them actually biting us or the dog. She gets regular flea and tick protection applied and it seems to work well.

We are off on an adventure today to another county. I relish a new place to hike and since we are taking a few weeks off as part of our “spring break”, the boys are eager to get outside in the sunshine. The predicted high today is around 70 degrees. Yahoo! So we are off to pack a lunch and fill up our water bottles to spend a day being refreshed by a new territory to discover.

Our Pine Tree Study: Winter Series #5

“There is something majestic about the pines, which even the most unimpressionable feel.”
Handbook of Nature Study, page 670

We have plenty of pine trees to study in our area and because they are so common we often don’t take the time to really look at them. This week as part of the Winter Series of Challenges, we tried to focus on two different kinds of pines that we have along our walking trail in two different spots.

The first is the Ponderosa pine and it is very common in our neighborhood. We also enjoy seeing them when we visit Yosemite.

These are really tall pines that spread out their limbs high up on the top.

Quite a few limbs had fallen down in the last storm we experienced, making observation of the limbs much easier. Here you can see how the bundles of needles are attached to the limb.

Ponderosa Pine trunks resemble puzzle pieces and have actually very pretty.

Here is another tree that has moss growing in between the bark pieces.

Now for the other kind of pine….

The needles on this pine are almost blue-gray in comparison to the Ponderosa Pine. This limb was down from the winter storm as well and we got to take a really good look at it up close.

This was interesting to see. I am assuming this is where the new cones will develop on the limb.

“The appearance of the unique unripe cone is another convincing evidence that mathematics is the basis of the beautiful. The pattern of the overlapping scales is intricate and yet regular-to appreciate it one needs to try to sketch it.”
Handbook of Nature Study, page 672

Here are some cones. We are not sure and will have to go back and look at the tree itself to identify it but the boys are thinking that it is either a Jeffrey pine or a Gray pine.

I attempted last summer to sketch and paint some cones into my nature journal and it is very true that when you take the time to sketch something you notice all the patterns and details much more than you would normally. I encourage you to give it a try with your children.

We have studied the pines in our backyard before and you can read about that study HERE.

“At least one pine tree should be studied in the field. Any species will do, but the white pine is the most interesting.”
Handbook of Nature Study, page 674

I think if you live in the West, the sugar pine is also very interesting, especially if you have a big cone to study.

Great week for nature study!

Outdoor Hour Challenge-Winter Series #5 Pine Trees

Outdoor Hour Challenge
Winter Series Ebook
Pine Trees in Winter
(See previous Pine Tree Challenge #32)

Inside Preparation Work:
This week read in the Handbook of Nature Study pages 670-675 to learn more about pine trees. Even if you don’t think you have any pines in your area, it is still interesting to read the information for future reference. Make sure to note the ideas suggested for studying pines in the lesson at the end of the section.

Outdoor Hour Time:
Spend 15 minutes outdoors this week with your children in your own yard or on your own street. This week you will have two suggested activities.

*If you have a pine tree of any variety in your yard or on your street, use the ideas from the lesson on page 674 and 675 to guide your observation of the pine tree.

Some ideas to get you started:
What is the general shape of the pine tree?
Is there one central stem running straight up through the center of the tree to the top?
What color is the bark? Is the bark ridged or in scales?
Study the pine leaves. Why are they called needles? How many needles in the bundle?
Does it have a cone?

*If you do not have a pine to observe or you would like an additional activity, take some time to lay under any kind of tree that is available. Look up at the branches. Listen to the sounds of the leaves. Try to spot some kind of wildlife in the tree. Have your children tell you with their words what they experienced while under the tree.

Follow-Up Activity:
After your observation time, use a field guide (see suggestions on the bottom of this post) to identify your particular pine tree. Make a rubbing of your tree’s needles. We have found this blog page to be especially helpful in identifying pines:
http://treenotes.blogspot.com/2007/07/identifying-pines.html

Make sure to give time and the opportunity for a nature journal entry. If you observed a pine tree, try to complete Exercise Ten of the lesson on pine trees: Draw a bundle of pine needles showing the sheath and its attachment to the twig; the cone; the cone scale; the seed. Sketch a pine tree. You could also include a leaf or needle rubbing in your nature journal this week. There is a notebook page included with the Winter Nature Study ebook or you can complete another Seasonal Tree Study page with your pine tree. As always, you are free to use a blank journal page in your nature journal.

Evergreens: Not All are Pine Trees

The moon from last week….

So here is my biggest revelation of the week: Not all evergreens that I see in the winter are pines….some are firs. 🙂 Both pines and firs are conifers (cone-bearing) but you can tell them apart by looking at the way the needles grow. Pines have bundles of needles and firs don’t.

That is my very unscientific description and understanding. It is good enough for me right now to recognize that I shouldn’t call all evergreens “pine trees” or even all cone-bearing trees “pine trees”. Sometimes it takes me a long time to catch on to things.

We noticed that there were some branches strewn across our hiking trail this week. Here is the first one.

We think it is White Fir.

Here is the second one that we observed on the trail. There was quite a bit of it in small branches all over one section of the trail.

We think this one is the Douglas Fir.

On another note, we have some fun stuff going on at our nature shelf.

We were surprised this morning to observe that the forsythia branches and the twig from our tree study have all started to show signs of blossoming. We brought them inside last week to “force” them to grow earlier than they would outdoors. If you want to try it, here are some instructions:
Forcing Forsythia (or other woody plants like p. willows)

Here is the first of the forsythia blooms.

Here is an attempt to take a photo of the complete branch showing the blossoms that are bursting out this morning in the morning sunshine.

Here is the sweet gum twig.

Isn’t that the coolest thing ever? How amazing and beautiful this twig is as it starts to bud out with the leaves…I assume these will be the leaves. I will keep you posted.

What a great week it is shaping up to be for nature study! These sorts of impromptu studies are the best. We had the field guides out and the magnifying lens at hand to observe the details. We are now deciding that we want to make a bigger space for all our nature collections. I will share what we come up with in the weeks to come.

Signs of a Squirrel: Our Outdoor Hour Challenge #45

Today ended up with a nature study of squirrels at my dad’s house. We had gone over to visit him this afternoon and somehow it was mentioned that we were studying squirrels this week. His eyes lit up and he took us out for a little walk on the backside of his property. He has been up there cutting wood and he had something to share with us.

This is what he wanted us to see up on the hill next to his woodpile. There was a whole area that was piled high with shredded pinecones. All of the reddish material that you see in this photo is the remnants of a squirrel feast. The squirrels have been very busy eating up in the trees and letting the litter fall to the ground in great heaps.

Here in the center, probably easier to see if you click the photo, are some of the many, many pinecones stripped of their tasty seeds.

Here is a closer shot of another cone.

Can you believe how big this pile is? They are busy squirrels.

Here one of the seeds from the cone after the squirrel has finished with it.

Now for a few more mammal signs from our walk.

We also saw these “signs” from some mule deer that live in this area. Just last week we saw seven deer walking down to my dad’s pond late in the afternoon. They seemed not to care that we were watching in awe of their beauty.

Then right down the hill from where we were, we saw these tell-tale signs of a busy gopher. You could not walk easily on this slope because the ground was just full of holes and tunnels.

Here is another view of one of the holes. My dad was thinking about making a new garden in this area but I told him he better think twice….deer and gophers don’t mix very well with a vegetable garden. Even though it is a perfect spot for growing with lots of sunlight, he would need to fence it like his other garden area….a very tall fence.

What a great way to study squirrels. My dad thinks of his property as a sort of nature study laboratory for our family. He will call us over if he sees something interesting and I love that about him. My dad and I did not spend much time together when I was a child because he was always working but now that he is retired, he and I share our love of all things that have to do with the great outdoors. He has not always been a fan of homeschooling but I think he now has changed his mind and is eager to help us out with our nature study.

Land of the Oaks and Pines: Outdoor Hour Challenge #32

We live in an area where the predominant trees are oaks and pines. Pines usually are taller than the oaks so it is easy to pick them out of the landscape. We can stand on our back deck and see dozens of pines and oaks. We have identified a few of them by name but we still have some trees to work on getting to know. The tall pine in the photo above we identified as a Gray pine or Digger pine. Pinus sabiniana. It is native to our area.

Pines are usually identified by looking at the needles. This particular pine has needles in bundles of three. The needles are a gray-green color and are about 7-14 inches in length.

Here is a cone that we found under the tree. Our field guide says, “They are brown, long-stalked, uneven-based, and equipped with strong, downward-pointing, 1/2 to 3/4 inch thorns. ”

Of interest to me, the seeds were once an important food of Native American. They also ate the buds and soft green cones from this pine. Of course, squirrels love the seeds too.

“The appearance of the unripe cone is another convincing evidence that mathematics is the basis of the beautiful. The pattern of the overlapping scales is intricate and yet regular-to appreciate it one needs to try to sketch it….The shape of the scales of the cone is another distinguishing characteristic of the pine, and sketching the outside of the scales from several different species of pine cones will develop the pupils’ powers of observation…”
The Handbook of Nature Study, page 672

It sounds like the basis of another day’s nature study to me. I will gather a few different cones and have them on hand.

This photo is my attempt to show you how the color of the needles on this pine are a gray-green color and not the dark green of some of the other pines we have in our area.

Now for a pine tree story. This pine is a Monterey pine and is not native to our area. They do grow naturally along the coast of California but we live in the Sierra Nevada Foothills. The previous owners of our home must have planted it in the yard and we have watched it grow in the last twenty years to a towering height over our property.

Earlier this year we cut down this huge Monterey pine. It had grown too close to our propane tank and out over the whole lawn. Its roots were pushing up the sidewalk and we were afraid it would soon get into the water pipe we have running from the front to the back of the property. It had to come down.

Here is a photo of the men in the tree as they limbed the branches and lowered them down. Some of the branches were as big as tree trunks. This was a mighty big tree. I could hardly watch the workers as the scurried up and down the tree trunk and then way out onto the limbs to cut sections off. Note the sweet gum tree in the foreground and how it has no leaves but the pine is still green.

Here is the trunk all neatly cut into chunks. We had a friend who took the wood and is drying it to use in their woodstove. We never liked pine to burn but some people love the heat it gives off. This was the perfect opportunity to observe the trees rings up close.

Here is a close up photo of the sap seeping out from the downed tree trunk. It was very sticky. I know from personal experience. 🙂

The other interesting thing to note about the pine was the thickness of the bark. The pattern of the edge was so pretty.

Here are some cones that came from the tree. I shared this photo before but it really shows how the cone opens up as it matures to allow the seeds to be exposed.

It was sad to watch the tree be cut down but now that it has been some months we can see the difference in the surrounding trees. They have ample sunlight now and they are filling out their branches. One oak in particular seems to have really benefited from the pine removal. Our lawn is so much greener now that it isn’t constantly covered in needles.

We will be observing more pines as the focus continues but I thought we could share our special tree cutting down story in this entry.

Outdoor Hour Challenge #32 Pine Trees

This may be a difficult focus since everyone has different kinds of trees in their area but I am going to attempt to cover a variety just to get you started and to show you how the Handbook of Nature Study can help you in your local area. I used the poll on my sidebar to gather data about what trees would be an appropriate choice for each challenge.

This week we will start with pines since 87% of those polled in my recent survey responded that they had pines in their location. The Handbook of Nature Study highly recommends studying at least one kind of pine tree in the field and then the leaf/needle or the cone indoors, one specimen per child. I realize that not everyone will have the ability to study a pine tree up close so do the best you can. Even if you do not have any pine trees in your area, you can still start to learn the difference between evergreens and deciduous trees.

Here is a link that will introduce the difference between deciduous and evergreens: EHow.Com.
Here is a web page that has lists of pines by region-worldwide! Make sure to scroll down to find your particular area.

Outdoor Hour Challenge #32
Trees-Pines

1. This week read in the Handbook of Nature Study pages 670-675 to learn more about pine trees. Even if you don’t think you have any pines in your area, it is still interesting to read the information for future reference. Make sure to note the ideas suggested for studying pines in the lesson at the end of the section.

2. Spend 15 minutes outdoors this week with your children in your own yard or on your own street. This week you will have two suggested activities.

*If you have a pine tree of any variety in your yard or on your street, use the ideas from the lesson on page 674 and 675 to guide your observation of the pine tree.
Some ideas to get you started:
What is the general shape of the pine tree?
Is there one central stem running straight up through the center of the tree to the top?
What color is the bark? Is the bark ridged or in scales?
Study the pine leaves. Why are they called needles? How many needles in the bundle?
Does it have a cone?

3. After your outdoor time, spend a few minutes discussing any trees you saw. Talk about anything that interested your child. Maybe they brought home a leaf or a cone to examine and you could look at them with a magnifying lens. This would be a good time to look up any pine trees you observed in your field guide and see if you can learn more about your particular pine tree.

4. Make sure to give time and the opportunity for a nature journal entry. If you observed a pine tree, try to complete exercise 10 of the lesson on pine trees: Draw a bundle of pine needles showing the sheath and its attachment to the twig; the cone; the cone scale; the seed. Sketch a pine tree. You could also include a leaf or needle rubbing in your nature journal this week.

5. If you identified a tree this week, add it to your list of trees in the front or back of your nature journal. You can also use the Running List notebooking page. Make a note indicating whether it is an evergreen or a deciduous tree.

You can purchase all of the first ten challenges in a convenient ebook along with custom notebook pages.
