First grade concluded their study of the Water Cycle and Weather by making ice cream in a bag to see how water can change from a liquid to a solid when the temperature is lowered. And then we ate our ice cream! YUM! If you would like to try this at home here is the recipe we used:
Ice Cream in a Bag: For every cup of milk (or cream) add 4 teaspoons of sugar. For vanilla ice cream add 1 teaspoon of vanilla flavoring or for chocolate add 2 teaspoons of chocolate syrup. Place the mixture in a Ziploc bag, seal it and then place inside a second Ziploc bag (in case the first one comes open or tears). Place your bag of ice cream mix in a large freezer size Ziploc bag or a large plastic container, add ice and about 1/2 cup ice cream salt, seal and shake until it turns to a solid. It will take at least 10 minutes. (If you have trouble getting it to change to a solid, add more ice cream salt to the ice.)
Second grade performed an experiment to see what solution would best clean the tarnish off of pennies. We tested 5 solutions: water and salt, water and sugar, water and soap, vinegar and salt, and vinegar and sugar. And the winner was the vinegar and salt solution!
Fourth grade used the scientific method to perform an experiment to learn “How many M&Ms are in a fun size bag?”. We found the average for all 5 classes was 15 M&Ms in a fun size bag. We also sorted the M&Ms by color and surprisingly found that instead of about the same amount of each color, we had significantly more blue and orange M&Ms than the other colors.
