  1. Units of CAPACITY

  2. Objectives • By the end of this lesson, students should be able to: • Distinguish among different units of capacity (L, cL, mL)

  3. Activity 1: Brainstorming with Capacity Capacity is the measure of how much liquid a container can hold. Note: Teacher to brainstorm with students about different containers that they know.

  4. Activity 2: Arbitrary Units of Capacity Let's see how many cups of water can fill this jug. 1. 2. 3. Note: Teacher to brainstorm about the difference in the number of cups required to fill the jug in each case.

  5. Activity 2: Arbitrary Units of Capacity Since we cannot use a cup as the arbitrary unit to determine the capacity of the jug we need to look for a standard unit. Remember the kg and g for mass!

  6. Arbitrary Units of Capacity

  7. Arbitrary Units of Capacity

  8. Activity 2: Arbitrary Units of Capacity Every container has a capacity. Here are some examples. Can you state the unit in which the capacity is specified for each container?

  9. Activity 2: Arbitrary Units of Capacity One unit for Capacity is Litre (L)

  10. The Litre (L) All of these containers hold 1 L.

  11. The Litre (L) This size bottle holds 2 L.

  12. The Litre (L) Some fish tanks can hold 50 L.

  13. Activity 3: Reading Capacities Observe the given containers and state the units used for their capacity Note: Teacher to provide students with empty containers having capacity in cL, mL and L, brainstorm on existing units of capacity and relate to the size of the container.

  14. Consolidation Work Which unit would be used for the following containers? Note: Teacher to provide students with empty containers having capacity in cL, mL and L and brainstorm on existing units of capacity.

  15. Consolidation Work Would you use mL to measure the liquid volume of a bathtub? Justify your answer. A. Yes B. No

  16. Consolidation Work Would 1 Litre be a good estimate for the liquid volume of this shampoo? Justify your answer. A. Yes B. No

  17. Consolidation Work Which is the better estimate of the liquid volume of this pot? Why is it so? 2 mL 2 L 2 cL

  18. End of Lesson 1: Units of Capacity
