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.

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Middle school or high school physical science pupils will warm up to the topic of heat when viewing this set of slides. It covers heat transfer, measurement tools, phase changes, and more. Have demonstrations and examples of the tools...

Explore the world (our world) of melting ice caps. Why are these caps melting? What is the effect of melting ice caps? Dive into the ever-present issue of global warming with a resource that has learners looking at data and participating...

Want your class to rock? Then try this boulder activity. Pupils learn about a specific boulder field and use edible materials to demonstrate the geological processes that formed this unique feature. Weathering, erosion, and mass...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

In this freezing and boiling point graph learning exercise, students use the graph illustrated to respond to several questions that follow. They identify what is the freezing, boiling, and melting point of the substance in the graph....

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

Students investigate the 3 states of matter. For this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...

Learners study global change and how these changes impact wildlife.  In this polar bears  lesson students analyze maps and data to understand climate change. 

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

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 explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

In this lab activity worksheet, students record the time it takes for an ice cube to melt in three different situations. After collecting data they design a container that will keep an ice cube in a solid state for as long as possible.

Students make a " science surprise" or ice cream in the lab. In this melting point depression lesson plan, students use various substances with ice to determine the effects on the melting point of ice and the ability to make ice cream....

Students explore what happens to the amount of different substances as they change from a solid to a liquid or a liquid to solid.

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third lesson of the series, learners conduct an experiment, demonstrating the flow of heat...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

In this science worksheet, students incorporate their knowledge of math to solve the given problems about freezing points through conversions. They convert from unit to the other.  There are 10 questions.

Students explain how melting glaciers affect global warming. For this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.
