Experiment 4: (above)
Take drops of food dye/water and drop two colors onto
a piece of coffee filter. What happens when the following
Experiment 5: (below)
Pour water into a white screw top lid. Add four M&Ms;,
one each of red, yellow, green and blue.
Make a prediction. What do you think will happen when
the colors meet?
**When the colors meet, they will form a solid line (at
least at first until the water is disturbed, someone eats
an M&M; or until enough time passes.
This is because the sugar is dissolving off all of the M&Ms.;
Where the food dye meets, the concentration of sugar is
the same and the sugar/food dye will stop moving outward.
