I recommend these printable science project plans for K-12 for hundreds of great project blueprints and this step-by-step guide for doing an award winning science fair project. Also be sure to check out these fun science kits as a fast, simple way to get started on your science experiment.

What You Need:

Milk
Food coloring
Liquid dish soap
Dish- wide rim

What To Do:

1) Pour milk into a wide rimmed dish, and let sit until it warms to room temperature
2) Place drops of different food coloring in the milk
3) Place two drops of liquid dish soap into the mixture

Demonstrates scientific principles: Surface tension

If you place a drop of water onto another surface, you will notice a sort of "skin" that hold the water into place. This is known as surface tension. In this experiment, the soap breaks the surface tension at that particular location, but the surface tension remains strong for the rest of the dish. This explains why the liquid disperses to other areas of this dish- due to broken surface tension.
