Take one box of rocks and dump them onto your sorting mat. Use the tools (magnifying glass, rulers, microscope, scale and others) to spot the ways the rocks are the same and different.
What are some ways you can put them into two piles? The rocks in each pile should be similar to each other in some way.
Once you find a way, sort the rocks and record the information onto your Sorting Rocks Worksheet. Be sure to tell how you are sorting them and draw a picture of each pile. Use the colored pencils or crayons to show color differences.
Try to find at least 4 different ways to sort the rocks. If you can think of more, try it out and write it at the bottom of your worksheet. Write down the tools you used while sorting your rocks. Be as creative as possible.
Put all of your rocks back into the box, return your supplies and tools the proper place, and turn in your worksheet to the teacher!</li></ul>ASK THE TEACHER IF YOU HAVE ANY QUESTIONS!<br />-685800457200Scale<br /><ul><li>Scales tell us the weight of an object.

You can even change how close up you see the objects.
