CAN'T TOUCH THIS!

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

And they are off! Using Styrofoam meat trays and balloons, individuals build racers that demonstrate Newton's Third Law of Motion. Pupils run their racers three times and make improvements between each trial. To conclude the activity,...

Young scholars discuss how small they must cut something before it is no longer fundamentally the same. An online activity challenges and engages pupils in learning about the periodic table. Two hands-on activities cover elements and...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

In this airplane worksheet, students compare the mass of an airplane to the mass of a paper clip airplane to see if the mass determines the best flight. Students complete 5 trials for each.

Middle schoolers examine the relationship between radioactivity and radon. They practice using a geiger counter with different materials. They answer questions to complete the lesson.

Drop a perfect project into your lesson plans. Groups use different building materials to create models of parachutes for food drops. After testing out their prototypes, they make improvements to their designs.

Several radioactive concepts are explained with the help of animated atoms, complete with their own facial expressions. As physical science pupils watch, they learn about gaining or losing atomic particles, alpha and beta particles, and...

Why is wood good for building houses, but not the best choice for high-rise apartments? Future materials scientists put building materials to the test using a hands-on interactive. Pupils pull and push on substances such as reinforced...

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science class....
