Motion and Speed

Step 1. Questions

Different species move in different ways. A fish swims through water. A kangaroo hops from place to place. A snake slithers along the ground. A cheetah runs with all four legs. Each of these species can travel great distances at high speed.

In this research report, you will explore speed and motion on Earth. To begin, read the following questions about things that move.

Think of at least three things that move. How fast does each one move? Does it move by itself, or does someone or something help it move?
How far does the thing move?
Where does it move

Step 2. Research

Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
