1. What is the exact mass of this carrot in grams?

2. In this lesson you will learn how to measure mass in grams by using a balance scale.

3. Mass is how much matter an object contains.

4. We can measure the mass of small objects in grams using a balance scale.

5. Not letting the scale balance before reading the mass Slightly off-balance Balanced

6. First, you put your object in one container.

7. Then you add a few weights

8. You keep adding weights as the scale gets closer to balanced

9. When the scale is balanced, you total the mass of the object 10 g

10. First, you put your object in one container.

11. Then you add a few weights

12. You keep adding weights as the scale gets closer to balanced

13. When the scale is balanced, you total the mass of the object 46 g
