Liquids

Another fun idea from Family Fun magazine to experiment with liquids:

The boys mixed several drops of green food coloring with corn syrup in the bottom of a clear glass.
Then they mixed blue food coloring with water in a separate glass and dumped the water slowly on top of the corn syrup.

Last we poured vegetable oil on top.

They dropped various objects to see which layer they stayed in. We used a plastic bottle cap, paper clip, penny, and a marble.

They were interested and amazed at how the objects acted in each liquid. I held off on teaching the word viscosity. Maybe in a few years. =)
