At the Indiana State Museum and Historic Sites, we are the keepers not only of facts and objects, but also of stories – and it’s part of our mission to share those stories with you. The purpose of this blog is to share the stories of our history, artifacts, volunteers, staff and more.

The Indiana State Museum and Historic Sites may be currently closed due to COVID-19 – but that doesn’t mean we can’t bring some of the museum to you!
On Tuesdays, we’re bringing families tons of educational content that’s easy for caregivers and their kids to do at home with materials you likely have on hand.
This week, we’re exploring ice!
Pure water forms a solid at 32 degrees Fahrenheit, or 0 degrees Celsius. When different chemicals are added to water, the freezing point can change.
In this exercise, see what effect certain household ingredients have on ice.
These are suggested items to use in your investigation:
1. Prep your materials. Place the ice in a tray or bowl, and prep the salt, sugar, baking soda and any other powders to test by putting about ¼ cup of each into separate containers.
2. Observe the ice and think about what questions you have.
3. Have your child determine what questions they want to investigate. Encourage them to focus on questions they can test with the materials on hand.
4. Let your child’s questions guide the experiment. For example, if they wonder how long it will take to melt a half cup of water, follow their lead and see how long it takes.
5. Next, explore with the materials. Some ideas to try:
Add a few drops of food coloring on top of the ice to better see the trails left as the ice melts.
During and after the activity, ask your child:
