This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

This is a classic exercise for visualizing the scale of the Solar System.

Many people think the different stages in the life of a star are actually different types of stars, rather than just stages in the life of a single star.
