Task: At this station, you will be observing the effect
of water on dots of different colors.
Materials:

Directions:
- In front of you are a small cup of water and a piece of cut
filter paper.
- Bend the tabs with colored dots upwards as shown in the diagram.

the small cup. Be sure the colored dots are above
the water surface, but be sure that each of the tabs is touching
the surface of the water.
