We All Scream for Ice Cream

Here is a good worksheet for 5th grade scientists. In it, they look at a bar graph that shows the freezing point for a variety of liquids. Then, they are given a scenario of a certain liquid melting and freezing, and must determine which...

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

We all scream for ice cream! Individuals create home-made ice cream in the classroom. This is a delicious way to show a real-world application of the freezing point depression to your class.

Steve Spangler has created a toy that relies on science to make ice cream! He uses a ball with two cylinders inserted. One contains rock salt and water, while the other contains the ice cream ingredients. Once sealed, a family kicks the...

Here is the recipe for making ice cream in a couple of zip-top plastic bags. It is a fun way to demonstrate phase changes, especially when the weather is hot! Use this in your elementary science curriculum when introducing the states of...

Why do bricks make terrible windows? Learn about how the different properties of matter, including transparency, reflectivity, and freezing, boiling, and melting points can help you observe what they are, as well as indicate their...

Water is powerful! Because it expands as it freezes, if it does so in a closed system, tremendous pressure can be created. All it takes is a little break to cause the system to explode! It's unlikely that you would submerge a pipe full...

Spangler leads an 11 year old scientist through the processes behind his science fair project, which was designed to see if any common household liquids (besides water) would expand when frozen. Liquids such as motor oil, ethanol,...

Students create ice cream in a zipped bag and measure the temperature of a salt/ice mixture. They discover how salt lowers the temperature necessary to freeze ice to a solid (below 0'C).

Young scholars discuss the freezing point of water. They make their own ice cream using ice and salt mixtures.
