I made a game for students using sample questions from the textbook and previous tests.
We did get to do an Ice Cream (Mixtures and Solutions) Lab with all of the 8th grade Science classes which was very fun!
Our recipe (for each lab group of 4 students):
2 cups whole milk
4 tablespoons sugar
1 teaspoon vanilla
1 quart freezer zipper bag
1 gallon freezer zipper bag
1/2 cup ice cream (course) salt
ice
Procedure
1. mix the 1st 3 ingredients in the quart bag and seal
2. put the quart bag in the gallon bag
3. add salt and ice and seal
4. shake bag back and forth for about 10 minutes or until the mixture has turned from liquid to solid
5. discard the gallon bag of ice and salt
Discussion
1. Define & Identify the solutes and solvent
2. Is the ice cream a solution, suspension or colloid? Explain each of these terms and describe the particle size in each.
Students bring in toppings to share.
