CAN'T TOUCH THIS!

Future physicists will be elated as they engage in a demonstration of radioactive decay that uses balloons and pennies. Balloons represent atomic particles and the students themselves are the atoms. After each flip of the coin, some of...

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...

Presenting a distinctly environmental point of view, this expansive set of three sessions guides learners to identify home-building materials and the resources from which they are derived, and to compare materials used by region and...

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...

Students discuss and identify chemicals which are considered hazardous. They create a poster of hazardous substances. They must show what the chemical is and how one can be exposed.

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....

Spanning across time—well, maybe not time. Using simple materials, teams design, draw, and then construct a bridge. Teams build the strongest, safest, and most economical bridge using the materials from the supply price list. Each team...
