Poor Sam! His graham crackers have undergone a physical change, so he can't make his s'mores! Mia explains that their molecules haven't changed, therefore they are still graham crackers. The two teens then discuss clues that would...

Energize your phase change lesson plans! Add a short but focused interactive into the mix and watch as pupils experience how states of matter react to changes in kinetic energy. The resource tracks the kinetic energy of a cold solid...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Let Einstein's work shine the way. Pupils read about Einstein's iconic equation, E=mc^2, using a remote learning resource and see how ideas from other scientists such as Kepner, Curie, Galilei, and Newton led to its discovery. They...

Pour on the knowledge with an engaging states of matter interactive! Young physical scientists view the atoms within a liquid to explain what gives a liquid its unique properties. The resource allows users to highlight and observe two...

For this petroleum products worksheet, students are given the components of crude oil and they graph the various products found in a 50 gallon barrel. Students complete an activity to determine if they have collected cards that represent...

Can you distinguish physical changes from chemical changes? After reading a brief summary of both types of changes, you'll be presented with some examples and asked to identify them.

This interactive allows you to explore the effect that temperature and pressure have on the changes in the states of matter. You can test these variables on carbon dioxide, hydrogen and water.

This lab is designed to have students find the relationship between the number of pulleys used and the force required to lift a mass. Students will see that it is not actually the number of pulleys that matter, but the number of strings...
