Tenth graders examine the heating curve of water when head is added constantly over time. They input values into a calculator as they record water temperature every thirty seconds as it is heated on a hot plate. They complete the...

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...

Young scholars examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

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...

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...

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

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.

Young scholars 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.

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Young scholars investigate the concept of a filter. They use simple supplies in order to construct one after watching a demonstration performed by the teacher. An important warning that the project water is not clean for drinking is...

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...

Using a colorful infographic handout and a guide sheet, hold a class discussion about how a bathtub can serve as a model for the greenhouse effect created by Earth's atmosphere. Participants will understand that as energy or matter is...

The learners construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.

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 describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

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 determine the amount of iron in a sample of cereal. For this iron lesson plan, students use a computer colorimeter to measure the amount of light absorbed by the solutions. They create a calibration curve using standard...

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...

Wind is a natural resource available around the world. Help your pupils appreciate the power and importance of wind by researching wind farms, making pinwheels, and designing windmills. 

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...

Young scholars make a windmill.  In this wind instructional activity, students learn background information about the windmill, complete an activity where they create a windmill, discuss using wind as a natural resource and...

Students come to see the exponential trend demonstrated through the changing temperatures measured while heating and cooling a beaker of water. This task is accomplished by first appealing to students' real-life heating and cooling...
