A group of adults come to our school from a local college to do hands-on science activities with the students. They get name badges with their first names on, but their last name is an element.
k-1 did some color testing on brown and black markers. They also mixed colors together to get other colors.
4-5 grades made glasses with 3-D lenses.
2-3 grades tested how liquids reacted with other liquids. They tried water with vinegar- mixed well. Then water with oil. Finally, they got a saucer with milk on it. The teachers dropped a few drops of food coloring onto the plate. Then we gave them a q-tip with dish soap on it. The children placed the q-tips into the milk. We saw some very cool things happen. I have some photos and videos of what happened.
