Session 1, Part B:
Which Rock Is the Largest?
In This Part: Measuring Surface Area | Measuring Volume | Measuring Weight
|
Some people might suggest that we examine the weight of rocks to determine which is the biggest. To measure the weight of your rock, you will need a two-pan balance and a three-arm balance. Note 7
Estimate the weight of your rock. (Later, you can compare your estimate with the approximate weight you've measured.)

Problem B7 |  |
What information can you gather by using a two-pan balance? Can you determine the weight of your rock with this balance? Note 8
If you have access to a two-pan balance, use it to determine the weight of your rock.

Problem B8 | |
How does a three-arm balance scale work? Can you determine the weight of your rock with this balance?
If you have access to a three-arm balance, use it to determine the weight of your rock.

Problem B9 | |
In science, a distinction is made between mass and weight. What do you know about these two terms? |

|
Problem B10 | |
How precise are your rock's measurements? What might affect the precision of this measurement? |
|
|
| |
|
Problem B11 | |
Now that you've experimented with several different types of measures, which would you use to determine the largest rock in a group of rocks? Should you use a combination of measures? Note 9 |

Problem B13 | |
Are there any other measurements you could use to determine the largest rock in a group of rocks? |
