Happy winter break y'all! I've been crazy busy working on a new unit and testing some of the experiments I found to go with it. We thoroughly enjoyed this SUPER SIMPLE experiment with changing states of matter today... making ice cream in a ziploc bag! I had done this before and found the instructions on teachnet.com. It was a delicious treat and a fun experiment for my daughter and I! I will be doing this in my classroom as we study states of matter with my new unit "All About Frozen Solids and other States of Matter."
Here are the ingredients and materials you will need for the ice cream experiment:
1/2 cup milk
1/2 teaspoon vanilla
1 tablespoon sugar
4 cups crushed ice
4 tablespoons salt
2 quart size Zip-loc bags
1 gallon size Zip-loc freezer bag
a hand towel or gloves to keep fingers from freezing
Don't forget to take your measuring spoons and cups to school!
Mix the sugar, milk and vanilla in a ziploc bag and place that bag inside of another bag.
Put the ice in a gallon size bag and sprinkle with the salt.
Place the double bagged ice cream mixture inside the bag of salted ice. Let it sit for about 10 minutes.
Take the double bagged ice cream mixture out of the ice.
Ours turned out to be soft serve, yummy and just like eating snow cream!
*****My Tip: It took about 30 minutes to get the ice cream somewhat frozen. I thought Ice Cubes and Kosher salt would be a good idea... maybe it would work quicker with crushed ice and table salt? Not sure!*****
My daughter and I had a lot of discussion as to why this works. It is still a bit complicated to me. The salt lowers the freezing point of the ice so as the ice becomes colder, the ice cream begins to solidify.
ANYWAY, it is a super simple (and delicious) science experiment and I hope you enjoy it.
Remember that I will have a 20% off sale this weekend just like every first weekend of each month.
Keep it simple!
