In Science we have been learning about weathering and erosion. On Thursday and Friday of last week we conducted an experiment using 5 different pieces of chalk. Each piece of chalk was put into a "weathering" situation. For example, one piece of chalk was placed in vinegar to represent the acid in rain weathering rocks. Another piece of chalk was scratched with a fork to represent an animal digging up rocks and weathering them. Ask your child what type of weathering had the biggest affect on the rock (chalk).
