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...

Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

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...

Young scholars model the arrangement of particles in a liquid. They use the model, to demonstrate how a gas is formed from a liquid with no increase in temperature as energy is added. Pupils model the arrangement and movement of gas...

Students are introduced to the laws of thermodynamics. The 1st law of thermodynamics states that the energy must be conserved when two objects of different temperatures come in contact. If one object gains energy, the other object must...

Students investigate melting and freezing behavior in substances. In this melting and freezing points lesson plan, students perform experiments to test the impact of various salts on the freezing point of water, they test the impact of...

Learners are told that objects in contact with one another reach an equilibrium temperature. A hot object placed in a cool liquid always cool off. It never happens that the object gets hotter and cool liquid gets colder. Students predict...

Students define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. Students conduct an...

This very thorough lesson plan has students 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...

High schoolers differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.
