The children had two bowls with jelly cubes in one of them. They had to transfer the jelly cubes to the empty bowl using only the handles of plastic spoons in order to test the friction of the jelly against the surfaces of the spoons and the bowl. They then repeated the same test, this time with the jelly cubes coated with vegetable oil where they found that this reduced the amount of friction making the task more difficult. The children have also used the perseverance gem for this lesson. |
