We had a very successful Force and Motion Fair this week! Students designed games that used force to work and explained how the games worked. We invited families to come play the games at our first annual Force and Motion Fair! We had a blast, and you can see the pictures from the night in the slideshow below!
In class we are learning about germs. We experimented with two peeled potatoes. One potato we touched with our hands and one we did not touch. Then we put them in a container. Then we waited. The next day, they grew some bacteria. The untouched one was whiter than the touched one. The touched one had more bacteria growing on it. By the end of the week, they both grew a little more bacteria on them, but the touched potato still had more.
On Monday, a zookeeper came. It was a lot of fun! We saw a snake and a Brazilian opossum. The snake was a king snake and the opossum was an adult. We felt the snake. The zookeeper taught us all kinds of stuff like...we learned how some animals are more scared of us than we are scared of them. Then he taught us about animal habitats.
In our class, we made a water cycle. We used cups, plastic wrap, and a rubber band. First, we put hot water in the cup. Afterwards, we put the plastic wrap over the cup. Then we put the rubber band over the plastic wrap. Then we set them close to the window so they could get heat from the sun. Finally, the heat from the water evaporated to the plastic wrap and turned back into liquid water drops through condensation. When the drops got too big and heavy, they fell as precipitation! In our next Science class, we made pictures of the water cycle to show what happens during the water cycle. After we were done, we added some glitter to the rain and snow. The things falling from the clouds are precipitation, the clouds are condensation. First, the water heats up from the sun and turns into a gas called water vapor. The water vapor goes up into the atmosphere that is very cold. When it hits the cold air, it turns back into a liquid and forms clouds, which is called condensation. Once more water comes into the clouds, they get so heavy and can't hold any more water. They let the water go, and it rains, snows, sleets or hails. This is called precipitation. The pictures below are some examples of our water cycles!
This morning we had the "Grow-Breaking" Ceremony for our Vermont School Garden! The whole school met outside, along with parents. Because we are using the harvest from our garden to help support the Empowering Children and Youths School in Sierra Leone, Africa, we even skyped them into the ceremony! Every class planted a wish stick with a wish that we have for the school. The whole school sang "Let it Grow" from the movie The Lorax. Mr. Knepp did the ceremonial dig and planted a seed. The fourth graders read a poem, and then the school in Sierra Leone sang a song that they wrote to thank us! It was a great ceremony! Below you can see pictures from today and watch an amazing video Mrs. Overn put together that chronicles the planning and creation of our garden this year. Watch for our class!
Here are some pictures from when we put the stakes in the Vermont Garden! We used the stakes and string to divide the different garden plots and leave space for pathways between each of them. Thank you to AC and JT's dads for coming to help us with this project! The garden will be prepped and ready for planting after this weekend! We hope to plant our Second Grade plots sometime in May!
We had a visit from the Zoo Outreach program this week! We learned all about animal classification, and we even got to see and touch 2 animals: an African Gray Hornbill and a baby alligator! Of course this happened to be the day when I forgot my camera at home, so we are borrowing pictures from Mrs. Lance's class. :) We can't wait until February when Zoo Outreach comes back to teach us about animal adaptations!
This week we began our Air and Weather Science unit. It is full of experiments, so we are having so much fun! We explored air and what it can do through a variety of objects: a straw, plastic bag, feather, cotton ball, balloon and styrofoam ball. We also tested what happens when you put a vial in a basin of water upside down and then tilt it. We had to figure out how to put a paper towel in the vial and keep it dry while it was underwater!
Take a look at some pictures from the first exploration we did!
Here are some questions for students to answer! Leave a comment on the blog with your ideas, and we're going to experiment to find out next week!
For our study of habitats, we researched specific habitats and created Trioramas to represent them. Check out the pictures below--they turned out great!
