As a geologist, you need to practice describing rocks in detail. It's not enough just to say "it's a rock". You need to be very specific and mention each of the properties that make one rock different from another.
Find a particularly interesting rock on your schoolyard. It can be either natural or man-made. Describe the rock in detail. If you aren't familiar with rocks already, refer to this web page. Here is a table that you can use to help guide you to describing rocks clearly. You'll describe the following properties:
Where did you find this rock? You may not remember in a few days, so write it down so that you can come back. Also, other people will be able to come see the rock you described.
Look at the grain shape. Are the grains sharp and angular? Or are they rounded? Or are they somewhere in between? Circle the words that best describe the rock you are looking at.
Is the rock hard and solid, or is it a bit crumbly?
This is space for you to write anything else interesting about the rock.

|All the same size?|
