Is There Life on Earth?
To find life on another planet, scientists look for gases (atmosphere), water, and temperatures that are not extreme. In this activity, groups of pupils become "Titan-ians," scientists who want to explore Earth for possible life forms....

Distance = Rate x Time
Every year, the moon moves 3.8 cm farther from Earth. In the 11th part of 22, classes use the distance formula. They determine the distance to the moon based upon given data and then graph Galileo spacecraft data to determine its movement.

Rings and Things
Galileo first observed Saturn's rings in 1610. Through the use of a flashlight and baby powder, classes see how they can observe the rings of the outer planets from far away. Another demonstration shows how these rings, made of ice and...

Modeling Sizes of Planets
The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...
