You are invited to travel to the edges of our galaxy, to visit planets and stars and other galaxies beyond. This is not science fiction, it is a real invitation. With just a few tips, you can visit space on your own or with friends.
When two different-colored lights shine on the same spot on a white screen, the light reflecting from that spot to your eyes is called an additive mixture because it contains the colors from both lights. We can learn about human color perception by using colored lights to make additive color mixtures.

Magnetic Field Activities for the High School Classroom
This unit is designed to acquaint the student with the magnetic field. The assumed average student has some familiarity with the uniform gravitational field of classical Newtonian dynamics and kinematics lessons. This is not required however. The unit is meant to introduce the idea of a field through investigations of magnetic fields as produced by various common magnetic materials and direct currents.
