Melting and Freezing

Here is a good learning exercise 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...

Students explore the physical and chemical properties of matter including phase changes and physical and chemical transitions. Information gathered is imported into video and edited to produce a movie.

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.

A teacher with talent has created a fun set of review questions on the changing states of matter. Cycle through 15 questions, multiple choice answers, and a monetary reward for guessing correctly. Use this game show PowerPoint to help...

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...

Students examine the processes of melting and freezing.  In this matter lesson students complete a lab in groups, discuss what they learned and view a teacher demonstration. 

For this science activity worksheet, students study the melting and freezing point of water with and without salt added to it. They observe the melting of an ice cube that has been sprinkled with salt and has piece of thread placed...

Students examine the different propereties of ice, such as freezing temperature.  In this scientific lesson students complete several activities using ice, like making ice cream.

Students experience problem-based learning as they use prior knowledge of the states of matter to keep a frozen juice bar from melting.

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...
