Predict when a Moon–Earth–Sun alignment can produce a solar eclipse.
This browser-based 3d simulation helps you predict when a Moon–Earth–Sun alignment can produce a solar eclipse. Designed for Grades 7–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.
Explore Eclipses, umbra, penumbra, alignment by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.
A typical investigation takes 5–10 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.
Predict when a Moon–Earth–Sun alignment can produce a solar eclipse. The main ideas are Eclipses, umbra, penumbra, alignment.
Yes. You can run the simulation online for free without creating an account.
Most learners can complete one investigation in 5–10 min. You can repeat it to compare more variables or improve your explanation.
