Learners construct a spectroscope out of a shoe box or mailing tube, diffraction grating, and other simple materials. They then use their spectroscope to observe spectra, the colors that make up light. Learners compare the spectra of various light sources. Use this activity to introduce learners to basic principles of light and color. Also, look at a related page about auroras to understand how distinguishing spectra of different atoms helps scientists understand the universe.
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns. Learners bend, twist, or press on the plates to observe patterns and then compare what happens when they place red plastic between the light source and the plates. Use this activity to introduce learners to constructive interference and destructive interference.
Exploring Tessellations (Grades 6-8)
In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle. This lesson features three investigations, in which learners make tessellations by translating, rotating, and reflecting the patterns.
In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized. The temperature at which this occurs is known as the Curie Point. This simple set-up involving a lantern battery and Tinkertoys demonstrates this phenomenon. Adult supervision required, as the wire will get hot in this activity.

Chordates - CrashCourse Biology #24
Hank introduces us to ourselves by taking us on a journey through the fascinatingly diverse phyla known as chordata. And the next time someone asks you who you are, you can give them the facts: you're a mammalian amniotic tetrapodal sarcopterygian osteichthyen gnathostomal vertebrate cranial chordate. (12:10)
Full Biography: Erwin Rommel
Erwin Rommel was a highly decorated officer in World War I and was awarded the Pour le Mérite for his exploits on the Italian front. Rommel soon caught the eye of Hitler and was promoted to field marshal.
