Here students push together two graham crackers, moistened with water where they meet. This investigation showed us how we can see fault lines on the earth’s surface, and how new structures can form (mountains, hills).
Students built solid structures from marshmallows and spaghetti. We then placed our structures on a tray of jell-o that was shaken for fifteen seconds. Only one collapsed. We have some good builders!
We have so enjoyed our mountains, earthquakes and volcanoes unit!
