Part 3: Circle the unit of measurement you would use to measure the mass of the objects below

We need to decide whether to use grams (g) or kilograms (kg) for each object.

> General Rule:
> - Use grams (g) for lighter objects (like fruits, small animals, snacks).
> - Use kilograms (kg) for heavier objects (like people, large animals, luggage).

#### a) Elephant
- Elephants are very heavy — thousands of kilograms.
✔ Circle kg

#### b) Mouse
- A mouse is very light — only a few grams.
✔ Circle g

#### c) Person (man)
- A human weighs around 60–80 kg.
✔ Circle kg

#### d) Apple
- An apple is about 150–200 grams.
✔ Circle g

#### e) Cheese slice

✔ Circle g

#### f) Suitcase
