The material an object is made of is very important in determining mass and weight. A big planet made of light material will weigh less, and have less mass, than a small planet made of heavy material.
A. Which ball weighs more, brown or green?
B. Which ball has more mass, brown or green? Which is made of the heaviest material?
C. Which ball weighs more, green or purple?
D. Which ball has more mass, green or purple? Which is made of the heaviest material?
Mission: Learn more about weight and mass.
Experiment:
Step 1.
Pick up the brown and green balls. Put one in each hand.
Step 2.
Ask yourself, do these balls have the same mass? Are they made of similar material? Let's find out.
Step 3.
Put the brown ball on one side of the scale and the green ball on the other side of the scale. What happens to the scale?
Step 4.
Take the brown ball off the scale and replace it with the purple ball. What happens to the scale now?
