The Science of Blood

p1170542

Yesterday, we took a trip inside our blood to learn about it’s composition. We put our items in the middle of our circle and explained that each of these items represent something that lives in our blood. We started with the large container of yellow water, which we were pretending was our plasma. We explained that plasma is a watery like substance that makes up large portion of our blood. At first, some students were not sure how it could be in our blood because it was not red, which lead us to our second ingredient: red blood cells!

We then added our red blood cells (red water beads) to our blood mixture. The students noticed that the more we added the red blood cells, the more the mixture appeared to be red than yellow. Because of this observation, they concluded that our blood looks red because of red blood cells.

Next on the list were the white blood cells (white beads). We then discussed how our white blood cells are the “soldiers” of our bodies that are always working to keep us from getting sick and help your body get better when you do have a cold or the flu.

platelets

Lastly, we discussed how our blood needs platelets (blue pom-poms) because they help our bodies create new skin or scabs when your skin is cut. Each child scoured their bodies for an old boo boo that they could share with the class and naturally they all had an elaborate story to go along with them.

Now that our students have spent some time learning about the composition of our blood, it’s time to learn about how the blood moves throughout our bodies. Bring on the giant, tape, floor heart! Hint: here’s what it looked like last year!

Let it snow, let it snow, let it snow

It was a blustery, wintry, picture perfect Forest Fours day today! Not only was there enough snow to finally go sled riding, but it was also great packing snow. We had giant snow balls and snow-people galore and many discussion about where the fairies go for the winter. We couldn’t have asked for a more perfect morning. I think it’s safe to say that our little snow bunnies quite thoroughly enjoyed themselves.

Drip, drip, drip

Sometimes it is the simplest things that brings joy to our lives. Watching a young child discover the properties of falling water fills me with joy. The wonder and inquiry that is involved is like no other. Somewhere along the way adults lose that wonder, until a child comes along and forces us to see the world through a fresh set of eyes.

Forest Fours Journals

Today, we introduced the students to a new chapter of Forest Fours by implementing a writing component to our day. Each child received a special journal that travels with us while on the trails. The students are allowed to draw pictures of the games that they are playing, the structures they build, or the specimens they see while out in nature (fungus, birds, rocks, deer, etc.). They also are allowed to collect things like leaves or small pieces of moss and tape them into their journals for safe keeping.

In addition to the journals, we borrowed four Polaroid cameras from Mrs. Weber so that the students can take pictures of items that would be too big to fit in their journals. The pictures are then taped onto a page and the students write about what they observed. The journals will travel with us each time we venture into the woods and the children are allowed to fill their journals to their heart’s content whenever they deem it necessary.

Since it’s inception, our class has used Forest Four days to play in an unstructured setting so that they could explore and create at their will. The addition of the forest journals allows students to extend their learning by giving them the opportunity to write, even while outdoors. Through this activity, the students are practicing skills such as fine motor development, phonemic awareness, self-regulation, observation, categorization, identification, and much more. We look forward to sharing our journal entries with you in the future!

What’s Gonna Work? Teamwork!

This week, the students became interested in a plank of wood that had been used as a part of the circuit on the nature playground. Our students decided to repurpose it and make a bridge on the large rocks. We spent many sessions working out how it could be used safely and problem-solving how to make it more stable for the students to walk on. Today, when the students ran outside to play with the “bridge” they realized that it had been moved to the ground by some of the older students. They immediately started trying to move it, but it appeared to be too heavy/large for just two students to move by themselves, so they began to enlist the other students from different sections of the playground to help.

When more people showed up to help, they positioned themselves around the plank of wood, lifted it up, and started swiftly moving around the rocks. Once they got near the rock that they wanted the bridge, they had to figure out how to  maneuver the plank without squashing anyone who happened to be on the other side. With some trail and error, a decent amount of determination, and a little bit of communication they had solved their problem! Not only did they get the bridge back into place, but they were able to stabilize their bridge so that students could safely walk across.

Nature Day: Forest Fours Edition

file_000-1

Yesterday, we joined together with the city campus Pre-K class for our annual Nature Day. Our nature explorers spent the whole morning playing, exploring, collecting, climbing, and making new friends. We even got to climb on a large tree that had been cut down on our property. The students couldn’t believe how big it was and were so excited when they figured out how to safely climb on top of it. We also spent some time introducing the new nature playground climbing structure to our new friends. We ended our picturesque day with a singalong and a picnic lunch. We are so excited that the students had some unstructured time to get to know one another and we cannot wait to everyone together again!

See Saw Science

Some days we are delighted to find that the students latch onto an idea or hypothesis and just run with it. Today, we were lucky enough to have one of our parents volunteer to read a story called Just A Little Bit by Ann Tompert that involved an elephant and a see saw. The whole book, the elephant tries to play on the see saw, but it just won’t work. He’s too big. Many animals try to come to the rescue by piling on the other side of the see saw but nothing happens. Nothing seems to work until a beetle lands on the animal group and the elephant finally gets to pop up in the air on the other side.

We talked about how this book teaches us about science and that we’re all really scientists. We do science experiments every day without even realizing. When you tell a silly joke and your friend doesn’t laugh, that’s an experiment. When you try a new food that you’re sure is going be disgusting and it’s actually delicious, that’s an experiment. When you launch yourself off the couch and land on your brother, that’s an experiment. (Let’s be honest, some experiments are safer than others.) Sometimes the experiment works and sometimes it doesn’t. What is most important is to ask “why?”. Why didn’t it work? What went wrong? How can you fix it?

Once the story was over, the students jumped at the chance to build their own see saws with our outdoor blocks. Many of the students started on a smaller scale with just one block as the base, while other’s were determined to make their see saws higher. After lots of tinkering and testing, it was decided that the higher see saws were not quite as safe and so we down-graded the amount of blocks that were being used. Some children added the colorful blocks to act as handles, while others used them as a weight so that they could try to see saw by themselves. Even Mrs. Forst joined in on the see saw fun!

There’s nothing better than a recess full of problem solving and physics.

 

Forest 4’s

This year, we are piloting a new initiative in Pre-K called “Forest Fours”. On each day four in our cycle, we are going to try to head out into the forest as soon as our entire class is present and we’ve completed our morning jobs. It is our hope that with a more extended period of time in nature, our students will have the opportunity to explore the natural world around them in a very authentic way. The students are free to play, explore, learn, and observe on our nature trails that weave around our beautiful campus.

Today we had our first opportunity to test out “Forest Fours” as the students spent almost 2 hours immersed in nature. We ate snack outside, climbed on our climbing trees, scooped up dirt, invented a new car game, played The Three Billy Goats Gruff, searched for walnuts, and learned new ways to care for the plants and trees on the trail. I’d say it was a success!

The Very Busy Caterpillar

p1130674-1

Last week, one of our students discovered a big, green caterpillar who was walking along the sidewalk that leads to our parking lot. We brought the plump little guy into the classroom so that the other children could observe him as well. After placing him in a clear container, we noticed that he had positioned himself near one of the top corners of the container and had started making long strands of silk from one side of the container to the other. Some students thought that perhaps he was growing more hair, while others knew right away that he was making a cocoon.

With the help of our fabulous science teacher, Ms. Capezzuti, we learned that our new friend was a Polyphemus caterpillar and would eventually turn into a moth. We also learned that Polyphemus caterpillars are silk caterpillars and can easily be reared indoors, so we decided to let our him finish making his cocoon in our container and release him after his metamorphosis. According to our research, he should emerge from his cocoon in about a week. In the meantime, we observed him while he finished making his cocoon and have been noticing what he looks like now that he is in his pupal case. We are looking forward to seeing him emerge from his cocoon, stretch and dry his wings, and then release him back into the wild! Yay, science!
