We had the best time learning about matter this week! First we learned about physical changes in matter using clay and unifix cubes. My students enjoyed weighing the objects whole then taking them apart and weighing them again to see if the weight changed. They found that the clay was .02 lighter than the original weight. They came to the conclusion that the .02 was some clay left on their hands or their desks.
We also made GAC to show Chemical changes in matter. My students LOVED getting to make GAC and play with it afterwards. Many wanted the recipe to make it at home!!
