Today's Classroom Activities :

Craters

Crazy Craters
Science Begin a study of craters by providing a large box of wet sand and some rocks of various sizes. Weigh and measure each rock. Drop each rock into the sand from the same height. Measure the crater that each creates. Drop them from a greater height; measure the imprint, and so on. Chart the results. Repeat the experiment with a box of dry sand or another type of soil. What conclusions can be drawn? How might scientists be able to determine what has caused craters or at what speed they were traveling just by studying the hole? Research various craters around the world.

The Moon's Craters
This lesson will help students understand impact craters and infer how they were formed and the reason for their differences in size.

Moon Craters Lesson Plan
Students will observe and describe the characteristics of objects in the sky and learn about how craters are formed.

Square Craters
Students can read about the square-shaped craters on asteroid Eros, a telltale sign of mysterious goings-on in the asteroid belt long ago.

Inside the Crater
Students gather information to examine the natural dynamics of volcano eruptions, identify five types of volcanic eruptions and their characteristics. Then they design and construct a 3-dimensional model of one type of eruption.
