Make things that float sink & vice versa

After learning float and sink; it is pretty easy for them to predict what could sink or float. However, we gave the children a challenge to make things that float sink and things that sink float.










This is the result of some of the items they came up with.

Leaves everywhere

The children have to collect as many leaves as they can. The one with the highest number of leaves is the winner.
After collecting the leaves; we observed how the children counted their leaves. Most of them counted one-by-one but two of them decided to arrange the leaves. One of them grouped the leaves in group of tens (clever ler...good idea)

After counting the leaves; one child asked "Why are all the leaves brown?" So, I gave them the challenge to find a green on the ground. They shook the tree and looked for green leaves on the ground but cannot be found. We discussed about leaves' ageing and changing colours.

How does the fish scale feel like?

Some of the questions pose to the children for them to find out:

How does the fish scale feel like when the fish is swimming?
How does the fish scale feel like when it is dead?
Is it easier to feel the scale when the fish is swimming?
How does the fish react when you try to touch it?
Will the fish bite you?
