Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

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...

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...

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...

Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

Sixth graders study heat, temperature, and heat transfer. Using probeware, the teacher demonstrates boiling points. Students participate in experiments and record the beginning and ending temperatures and mass of objects. After...

Young scholars complete activities to study the properties of solids and liquids. In this states of matter instructional activity, students investigate the melting and freezing of a range of materials in a virtual experiment. Young...

Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Tenth graders observe the processes of evaporation, condensation, melting, freezing, boiling, and sublimation. They do a quantitative investigation of the freezing of water, to explore explanations that involve particles.

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 define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

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.

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 scientific models worksheet, learners will use a model to represent matter in its various states. Students can use a computer graphics program, drawing on paper, or three-dimensional creation. Then learners will complete 3 short...

In this phase diagram worksheet, students answer questions about three given diagrams. They determine the boiling point, melting points and sublimation points for each substance. They also answer questions about the triple points and the...

Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...

Fifth graders examine both physical and chemical changes, and how to identify the difference between the two. They observe the changes that occur in butter when it is exposed to heat and cold, heat energy. In their notebooks, they write...

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

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...

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.

This very thorough lesson plan has pupils collect all ingredients necessary and work in pairs to make ice cream using plastic bags. They take temperature readings and record them on the chart as well as record findings on the...
