In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.
In this lesson students will calculate the size to distance ratio of the Sun and the Moon from Earth to determine how a solar eclipse can occur.
This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.
The Solar Eclipse Implementation Sequence provides a series of lesson plans for students to learn about solar eclipses.
