Every week, EVPL will be posting a new STEAM challenge for you to complete from your home! The challenge will run from Monday until Friday. Your parents can help, or you can complete the challenge on your own. We would love to see your creations! Submissions will be posted the following Monday when a new challenge is presented.
Summer is the perfect opportunity to become a food scientist! This week we are going to create food chemistry by making our own ice cream. Visit the EVPL YouTube page for a video demonstration.
Water freezes and ice melts at a temperature of 32° Fahrenheit; this is called the freezing point. Salt can lower the freezing point to -22° F, meaning it needs to be colder than 32° for water to freeze. That’s why we add salt to icy sidewalks and roads in the winter–to encourage the melting process. When you add salt to the bag of ice, it lowers the freezing point and the ice starts melting. When you add the milk mixture bag to the bag of ice, heat leaves the milk bag, and the temperature of the milk gets lower. Eventually, the milk mixture will freeze into ice cream!
Ages 3 and up. Younger participants can assist with adding ingredients.
Send a picture of your ice cream to firstname.lastname@example.org to be featured next week!
With 8 locations throughout Vanderburgh County, EVPL is ready to discover, explore, and connect WITH you! We encourage you to uncover new things, revisit old favorites, and to engage with us along the way.
