DOES AN ORANGE FLOAT OR SINK?

Does an orange float or sink in water? We began by filling a large bowl of water and placing an orange in the water. The K5 kids discovered that the orange floats. Then we peeled the orange, removing the rind. Next we placed the unpeeled orange in the water and guess what? It started to sink!
The rind of an orange is full of tiny air pockets making it float on the surface!





INTERNATIONAL VIDEO CONFERENCING FOR PROJECT POLAR BEAR CONTEST

Last Wednesday we joined the Virtual Award Ceremony by videoconference. We were able to connect with five other participating schools, and with Marissa Krouse and Alyssa McCall from Polar Bears International. Although there were some technical difficulties and interferences at the beginning it was amazing being connected with each other in one place while spanning 3 countries, and all to celebrate the passion and commitment to saving Arctic sea ice! Alyssa McCall, a biologist, answered our questions regarding Polar bears.

We finished the videoconference from the teacher’s room because it lasted until 5.18 pm!
