Your introductory physical science class will be energized by this PowerPoint. They will be able to define energy, work, and power. They will be able to perform calculations for kinetic and potential energy. They will be able to describe...

Start this series of lessons with a bang! Five exothermic reactions are outlined in this resource, including a demonstration that produces both light and sound. In the lab, chemistry apprentices record temperature changes, make hand...

Instructions for series of six activites, a reading of scientific literature, and a choice of six assessments await you in this physics resource. Well-written plans guide you in guiding your pupils to experiment with levers, pulleys,...

What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision....

Students study the factors affecting permafrost temperature and condition. In this physical science lesson, students observe local places with snow cover and collect temperature data. They create a short video about permafrost.

Sal's series on the Law of Thermodynamics continues with this video on how heat and work are added to, or taken away from, a system. As a result of the heat and work energy, the system that is being worked on will transform into another...

Engage young scientists in the upper-elementary and middle school grades with this collection of simple experiments. Whether you're teaching about heat transfer, density, or potential energy this resource has a lab for you.

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

After a brief reading on conduction and home heating systems, middle schoolers design a comparison experiment of temperature change in both hot and cold water. They will need to write up their own lab reports even though the procedure...

After viewing images of energy resources used for generating electricity, the class discusses the process of transformation. In pairs, they work on describing what they see in a diagram of a power plant and in graphing its energy data. 

If you can find Tinker Toys™, then this may be a fun assignment for your physical science class. Using the construction set and a few other toys, they examine the forces involved when it they are being played with. For each, they...

Students research the type of chemical reaction that occurs when metal rusts. They conduct an experiment looking at the rate of corrosion in steel wool. This is lesson three in a three lesson unit on the transfer of energy.

Budding chemists achieve a basic understanding of the role of heat in chemical reactions. An online worksheet gives learners instructions and questions to answer as they investigate the Chem4Kids website and perform a hands-on lab...

The laws of thermodynamics raise the temperature in your classroom when physics pupils complete this worksheet! They demonstrate their understanding by calculating specific heat capacity, final temperature, amount of work done, and more....

This learning exercise would make a nifty quiz on the laws of thermodynamics. Nine multiple choice questions assess high schoolers' understanding of energy transfer, specific heat capacity, phase change, fusion, and vaporization. It is...

When high school physics learners are studying specific heat, you can offer this resource to help them practice performing calculations. There are two pages of problems to solve. You could assign them together as homework, or separate...
