📏 Part 1: Choosing the Right Tool

1. Which tool would be BEST for measuring 50 mL of water accurately?

Large measuring cup (1 litre)

Small graduated cylinder (100 mL)

Kitchen spoon

Bucket

2. You need to measure 2 litres of juice. Which tools would work well? (Choose all that apply)

2-litre measuring jug

500 mL measuring cup (used 4 times)

50 mL graduated cylinder

1-litre measuring cup (used twice)

3. Convert these measurements:

a) 2.5 litres = ________ mL

b) 750 mL = ________ litres

c) 1,250 mL = ________ litres

🔬 Part 2: Recording Measurements

4. Look at the graduated cylinder below. What volume is shown?

(Imagine the water level is at the 85 mL mark)

Volume = ________ mL

5. You measured these liquids. Complete the table with the correct units:

Orange juice: 250 ________

Milk in a bottle: 1 ________

Medicine dose: 5 ________

Water in a swimming pool: 50,000 ________

6. Before measuring, estimate the volume of a standard water bottle. Then explain your thinking.

My estimate: ________ mL

🎯 Part 3: Problem Solving

7. Sarah needs exactly 1.5 litres of water for a science experiment. She has a 400 mL measuring cup. How many times must she fill it to get close to 1.5 litres? Show your working.

8. Extension Challenge: A recipe calls for 750 mL of milk, but you only have a measuring cup marked in litres (with 0.1 L divisions). How would you measure the milk accurately?

9. Explain why it's important to read a graduated cylinder at eye level when measuring liquids.
