Design a boat
Plasticine, plastic container, peas and water
We worked in pairs in class. Each pair got two strips of play dough.
We rolled the plasticine in our hands to make it soft.
Using our hands we shaped it into a boat.
We experiemented with different shapes of boats to see which would float.
We tried to mould many shapes for the boat to make it float.
We discovered that a boat with a wide base and curved up sides was the best shape for floating.
When our boats were floating we put in the peas as our passengers.
We counted the peas as we added them to the boat.
We kept adding peas to the boat until it sank.
which would make the best boat.
