For this science experiment, we explored mixtures and solutions...
For the activity, I used the following items:
-pack of dixie cups
-package of chex mix
-3 clear solo cups (+water)
-food coloring (any color)
-1 large bowl
I gave each student a copy of the worksheet (the product you are purchasing) before we did the activity. We started first with mixtures. For this portion, I put all the chex mix in the large bowl and told the students to draw what they saw in the "after" portion of the mixture. I then put a scoop of the mixture in each dixie cup and gave each student a tissue. I asked the students to sort their chex mix into groups. I then had them draw what they saw before. (Another way you could do this, would be to have each student bring in their own snack items... cheerios, chex, cheese-its, etc... they could all come dump them in the mixture pot then sort...) :) Then I asked the students to explain to me what a mixture actually is (a combination of different things that are mixed together, but not dissolved in a solution).
For the solution part, I had three volunteers each fill up a cup of water. I made one cup dilute (using only 1-2 drops of food dye), one concentrated (using 3-5 cups of dye), and one saturated (using about 10 drops or enough so that the dye would gather on the bottom of the cup). I had the students draw what they saw and tell me what a solution was.
Through this experiment, they were able to understand the difference between mixtures and solutions. :)
