Inquiry based lesson: Does it float or sink?
Introduction:
Ask the children to think about materials that float or sink in water. We will now look at theses materials to see which ones float or sink. The children will be asked to guess what happens to the objects when placed in water.
Development:
The children will be divided into small groups. They will be given a basin of water and objects such as a straw, plastic bottle, pebble, ball, piece of lego, paper clip, shampoo bottle, metal spoon, plastic spoon, twig, plasticine, sheet of paper and a plastic cup.
A child will record which objects floated and which objects sank.
The children will then try to explore the idea of creating an object that will float from the materials.They will work in their groups to explore their ideas.
Conclusion:
They children will show their assembled objects to the class and demonstrate which ones floated most effectively.
