Suppose you were to travel to the moon. What are some things

about you that might change? What would stay the same?

What is Matter?

What is Mass?

• All the solids, liquids, and gases that make up an object.

• All the “stuff” in the world

• Mass is a measure of how much Matter or “stuff” is in an object.

• We measure mass using a triple beam balance.

• Unit is grams.

Page 4: Mass

Do Not copy this slide!Mass is NOT the same as weight!

• Weight is a measure of the force an object experiences because it is being pulled by gravity.

• Weight= mass x pull of gravity • Your weight is less on

the moon because the pull of gravity is less.

• Mass stays the same because the amount of matter that you are made of stays the same.

Tape/glue in TBB and label…

*Beams have grooves for riders to sit in at each labeled mass. Rider should never sit between grooves!

Page 7: Mass

Steps to use a Triple Beam Balance (tbb)

1. Move all riders to far left groove.2. Pointer should be at “Zero.” If not,

turn the adjustment knob.3. Place object on tray.4. Start with the largest rider. Slide

rider to the right into each groove until pointer hits bottom of the marker, then slide the rider back one groove.

5. Do the same for the next largest rider, then finally the smallest until pointer points to “zero.”

6. Add the mass shown on each beam to get the total mass of the object.
