Learners investigate how water changes state. For this water lesson, students observe, measure, and describe water as it changes state. This lesson includes extensions which can be accessed via the provided web links.

Students experiment with water and ice. In this states of matter lesson plan, students explore how water can change from a solid to a liquid and back again. They discuss and write about the results of the experiment in a science journal.

In this energy from hydrocarbons instructional activity, students read about endothermic and exothermic reactions and how hydrocarbons release heat as fuels. Students read how to measure heat changes in reactions and practice finding the...

In this calorimetry worksheet, students determine the specific heat and the heat of neutralization in the 2 problems they solve.

Eleventh graders investigate the relationship between heat and energy transfer. They review terms including heat, work, calorimetry and the procedures for an experiment. After assembling the materials for the experiment, they observe...

Students test 4 materials to see which would be best for use as a heat mass. They then graph the temperature verus the time of the substances and decide which material would make the best heat mass.

Students observe the state changes in water. In this matter lesson plan, students observe, measure, and describe water as it changes state. Students explore how water can change from a solid to a liquid then back again. They journal...

How do plants and animals survive in habitats with very little water? Explore arid ecosystems and the way their inhabitants have adapted with a lesson and science experiment. After kids listen to a presentation about adaptation, they...

Who likes magic shows? In the fourth of five lessons, pupils view a scientific magic trick. The ball fits through the ring easily, but then moments later, it won't pass through anymore. What changed? Can we reverse the change? Scholars...

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...
