7th Grade Study Guide

Test Date: 09/18/15

The test will cover: metric conversions, length, volume, mass

*Use this study guide and your notes to know the following information for the test*

Metric Conversions:

- Know that the metric system is based on the number 10

- Why is it important for us to know about the metric system?

- Know what K H D , D C M stands for

• What prefix does each letter stand for? Example: K = Kilo
• Remember do not skip over the basic units (meters, liters, and grams) when doing conversions!

- Know how to convert a number from one unit to the next using KHDUDCM

• If the units are moving from left to the right, the decimal moves to the right
• If the units are moving from right to the left, the decimal moves to the left
• Do not skip the “basic units” space when converting!
  

**I will not provide you KHDUDCM for the test, so remember:

Length:

- What is the basic unit for length in the metric system?

- What tool is used to measure length in the metric system? (Hint: it is not a ruler)

- Know how to measure the length of something using the proper tool and units

• Remember, if you are measuring something very small, you will probably use centimeters or milliliters
• If you are measuring something very big, you might use meters or kilometers

Volume:

- What is volume?

- What tool do we use to measure volume of a solid?

- What units do we use to measure volume of a solid?

- What is the formula for the volume of a box-shaped solid?

- What tool do we use to measure volume of a liquid?

- What units do we use to measure volume of a liquid?

- What is a meniscus?

- How do we use the meniscus when we measure volume?

- What is water displacement?

- Give an example of water displacement

- Why do we use water displacement?

• (What types of objects do we measure using water displacement?)

Mass:

- What is mass?

- What tool do we use to measure the mass of an object?

- What units do we use to measure mass?

- If we are measuring the mass of a very large object, what units might we use?

- If we are measuring the mass of a smaller object, what units might we use?

- What is the difference between mass and weight?

** If you have questions, please ask Ms. Sparacino in advance- I am more than happy to help, but please do not wait until last minute to study!
