This illustration from the Lunar and Planetary Laboratory shows the approximate sizes of the planets relative to each other. Note that the planets are not shown at appropriate distances from the Sun.

While a ray diagram may help one determine the approximate location and size of the image, it will not provide numerical information about image distance and image size. To obtain this, students are introduced to the Mirror Equation and...

This task asks students to apply the Pythagorean Theorem to find the approximate number of yards two players ran during a football game and compare their distances. Aligns with 8.G.B.7.

Explore bats' navigation systems by experimenting with echolocation. Approximate an object's distance by analyzing reflected sound waves, measuring the delay in sound and calculating the ratio to the speed of sound.
