Fifth graders had fun last week making witches potions with items like snot, crushed bone, and other Halloween named items. They had to make a potion that bubbled. To do it they needed to mix vinegar and baking soda.
Third graders were being automotive engineers and had to design a cart that could roll. This was quite a challenge but many of the groups were successful.
The second graders are being civil engineers and building bridges. They are continuing to work on using solids made of different materials like metal, wood, plastic, etc.
