In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass. This is a simple trick that involves several complex physical...

In this activity, learners discover that atoms and ions of different metals will change places. Learners place drops of copper sulfate solution onto a steel nail, then observe as the solution loses...

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle. The marshmallows will...

In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass. They will be especially shocked when you hold the glass over their head and...

This is a quick and simple demonstration about reflexes (second activity on the page). During a discussion about the brain and nervous system, the educator slams a book on a table to create a loud...

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open. Learners will discover that hard-boiled eggs are much easier to...

Learners build a simple one-cell battery and use an ammeter to measure the flow of current. They add solutions of sodium sulfate and copper sulfate to separate bowls, and connect the solutions with...

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge. Use this...
