| ActivityDye in Water | Individually predict what will happen to water if you drop in a drop of dye. Write a prediction and draw a model. | | Play close attention to what happens to the dye as it hits the water. | | Why does the dye spread or diffuses into the water? | | Draw and explain this process individually first. | |
| Now discuss with your group what happens with the dye. | | Why does it spread out in the water? | | If you could look at this process under a strong microscope, what would you see happening? | | Come up with a group model to share with the class. | |
