I do a lot of public speaking, professional development workshops, teaching, and writing. Topics include astronomy, physics and physical science, the process of science, science vs. pseudoscience, astrobiology, science teaching, and -- new -- a presentation on the 2017 solar eclipse. Author of the "Phenomenon-Based Learning" series of books on teaching physical science (published by NSTA Press). See

Eventually have them make a scale model of the solar system. But first have them design it, discovering that it's pretty much impossible to make a good scale model of the solar system that will fit in the classroom. What grade is this for? Matt

Natalie, I'm not sure where in Ohio you were, but if you were in an area with 85% obscuration of the sun, you wouldn't have noticed any changes outside, even without the rain. For April 8, 2024, plan a field trip to be near the center of the path of totality, e.g., in northern Ohio. Matt

Phases of the Moon

2 Resources

This activity allows students to observe how the changing phases of the moon correlate with the moon's position in the sky. Using this information, students formulate a hypothesis for explaining the changing phases of the moon. Note that this activity also provides an example of the correct use of the word "hypothesis" as a possible explanation of some observed phenomenon (not a guess at the outcome of an experiment).
