Collisions and Momentum: Bouncing Balls
As a continuation of the theme of potential and kinetic energy, this lesson introduces the concepts of momentum, elastic and inelastic collisions.

Students explore these concepts by bouncing assorted balls on different surfaces and calculating the momentum for each ball.

Tires and ecosystems
Tires are one of the worst things that can be thrown into a landfill. They take up a lot of room and they can collect rainwater that is a prime breeding ground for mosquitoes. Tires can be repurposed, or used for other purposes, such as tire swings and playground toys. They can also be recycled and used to make school gym floors and shoes.
Things animals build
Animals typically build things so they have a place to live in as a shelter. Others are used to trap food or provide room and comfort for offspring.

Polar: PIXIE at Perigee on May 11, 1999 (North)
On May 11, 1999, the solar wind that blows constantly from the Sun virtually disappeared. Dropping to a small fraction of its normal density and to half its normal speed, the solar wind died down enough to allow physicists to observe particles flowing directly from the Suns corona to Earth. This severe change in the solar wind also drastically changed the shape of Earths magnetic field and produced a rare auroral display at Earths North Pole.
