6th Grade – Metric Mass – Mid Term

Flashcard maker : Charles Clay
What is the basic unit of mass in the metric system?
Gram
What apparatus is used to find mass?
Triple Beam Balance
What is WEIGHT?
The gravitational pull on an object.
What is MASS?
The amount of matter in an object.
What happens to your weight and mass if you were on the moon?
If you were on the moon your WEIGHT would DECREASE because the amount of gravity has decreased. However, your MASS would remain the SAME.
Write the abbreviated version of the metric chart.

Depending on what is being asked the G = Gram could be changed to L = Liters(volume) M = Meters(distance)

What are the 3 Mass Methods?
1. Measuring Mass Directly
2. Finding Mass by Difference
3. Measuring Out a Substance
Measuring Mass Directly
Used to find the mass of an object.

Step 1 – Place the object on the pan.
Step 2 – Zero out the TBB.
Step3 – The mass is determined by the positions of the riders. Record the mass.

Finding Mass by Difference
Used to find the mass of a liquid in a container.

Step 1 – Measure the mass of the beaker(a).
Step 2 – Pour in your liquid.
Step 3 – Measure the combined mass(b) of the beaker and the liquid.
Step 4 – Subtract the mass of the beaker(a) from the combined mass(b).
Therefore, b – a = Mass of Liquid

Measuring Out a Substance
Used to obtain a specific amount of a substance.

Step 1 – Find the mass of a paper plate. Record mass.
Step 2 – Add the mass of the paper plate to the desired mass of the substance.
Step 3 – Preset the riders to the amount (the sum) in Step 2.
Step 4 – The substance is then placed on the paper plate a little at a time until the zero pointer is balanced with the zero point.
