Bill Nye: Baseball Moon
Try this at-home science experiment to make your own Moon model and see how the Moon's phases change.
Sophia Learning
Sophia: Bill Nye: Baseball Moon
Bill Nye explains the phases of the moon with an experiment using a baseball, a lamp on a table, a dark room, and a stool or chair that swivels. As the person moves around, the changes in reflected light show the phases of the moon. The...

Teach Engineering: Lunar Learning
Why does the Moon not always look the same to us? Sometimes it is a big, bright, circle, but, other times, it is only a tiny sliver, if we can see it at all. The different shapes and sizes of the slivers of the Moon are referred to as...

Science Buddies: What's the Point of Boiling?
You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Teach Engineering: How Cold Can You Go?
Students explore materials engineering by modifying the material properties of water. Specifically, they use salt to lower the freezing point of water and test it by making ice cream. Using either a simple thermometer or a mechatronic...
