It’s been all about sound in second grade science. In the last few weeks students have learned that sound travels in waves of vibrations, the difference between pitch and volume, and that different sized vibrations create different pitches. Next week students will create and build their own musical instruments.
Students explore tuning forks in the pictures below:

The first graders are deep into their study of liquids. We’ve done experiments to learn about the ways that liquids are different from each other: thickness, color, texture, use, edible vs. non edible, etc. We’ve talked about the two ways that all liquids are the same: they can all be poured and they take the shape of the container they are in. Below are some pictures of the students engaged in water play with graduated cylinders, beakers, clear tubes, turkey basters, and funnels. I was reminded of how important a role play has in scientific discovery when one student said, “When I put weight into the water, the water level rises up.” This comment led to a class discussion of Archimedes, his bathtub and the king’s crown.

The Second Graders have been studying some of the major systems of the body: skeletal, muscular, nervous, circulatory, respiratory and digestive. As students learn about their major organs, they color pictures of them, cut them out, and paste them onto their body tracings.

Rolled newspaper and lots of tape = lots of busy fun!
Inspired by the building that they saw the First Graders doing, the Kindergarteners did their own building – with newspaper. Either working by themselves, or as part of a group, Kindergarteners crafted geometric designs, rafts, Knuffle Bunny style windows, houses and boats – anything their imaginations could come up with! Give it a try yourself the next time everyone is stuck indoors on a rainy day.

For a short unit on Design Technology, First Grade students were given the task of building a truck out of everyday building materials. There were two requirements: the truck had to be able to transport an apple and it had to be able to roll. Students were given a tour of the available materials and then told that they could go to work.
For the first 15 minutes of that work period, a total hush came over the class. I have never heard the students be so quiet! I could have heard a pin drop. Everyone was so busy thinking, concentrating and planning that no one spoke for a long time. Once students had a picture in their heads of what they wanted their cars to look like, the room got louder again as people gathered supplies and brainstormed together. I loved watching students help each other problem solve and volunteer ideas back and forth. The room had a really nice community feel to it.

Last week one of the first grade students asked me, “When are we going to do real science? You know, where we mix stuff together and there’s an explosion?” I was intrigued and decided that I wanted to find out more about what students were thinking in regards to science. The next time the students came to class I gave them pieces of paper with the words, “A scientist is…..” and asked them to finish the sentence and do a drawing to go along with their words. A few students wrote that scientists made potions. Several wrote that scientists made explosions. One or two wrote that scientists discover things. One student wanted to write about what mad scientists do, but I clarified that we were talking about regular scientists.
For our next lesson I took the same group of students out to the garden, where we turned our compost pile with a pitchfork to aerate it and observed the decomposition that had already taken place. We also placed a carved pumpkin in one corner of the garden and I explained that we were going to spend the next couple of weeks and months observing the pumpkin decompose. When we got back to the classroom, I asked the students to turn to the person next to them and talk for two minutes about the following question, “Is what we just did – turning the compost and placing the pumpkin in the garden – science?” I got a range of answers. One pair of students felt that what we had just done wasn’t science because it was something that they could do at home with their families. Another pair felt like it was science because what we had done reminded them of a lifecycle. The pumpkin would rot, provide nutrients for the soil, which would allow other plants to grow and produce; those plants would die and the cycle would continue. Needless to say, it was an interesting conversation.
For the next lesson, I read two books to the children. One book, What Are Scientists?, talked about how scientists study everything and highlights all the different “ologists” that there are in the field of science. The second book, What is a Scientist?, talked about general things that all scientists do. “A scientist asks questions and tries different ways to answer them. A scientist notices details. A scientist draws what she sees” etc.
Hopefully these experiences have helped the first graders to at least start to think more broadly about what science is and what scientists do, and maybe, just maybe, to move past explosions!

As part of our unit on Sunshine and Shadows, Kindergarteners were introduced to the idea of shadow puppets. Students created their own puppets and then acted out the poem, “There Was a Little Turtle”. Click on the link below to watch a sample.

We’re coming to the end of our Pond Unit in Second Grade. Students have had a lot of fun investigating the three ponds around BCD: the big BCD pond, Janet’s Pond – the small pond and wetlands area behind Peterson, and the Stockbridge Bowl across the street. We’ve taken water samples from each and looked at algae under a microscope. The students just finished making a wonderful Pond Life mural that you can see for yourself here in SESL – stop on by! Also keep a lookout for Science Journals coming home soon.

First Grade students have been spending time in the garden recently, weeding and planting garlic and winter rye seed. Students have collected soil samples from different areas on campus and compared them. They have also been diligently filling up their class compost bin. Our compost pile is growing rapidly!

The Kindergarteners have been busy since my last post! They have been helping out in the school garden, going on nature walks and exploring Sunshine and Shadows. Students are learning how shadows form, both inside and outside. On a rainy day students used blocks and flashlights to create “Shadow Cities”:
Students have also recently made sun art prints and traced their shadows to see how their shadows changed throughout the day.
