Learning outcomes:
To measure volume of water in different containers using non-standard units.
Materials:
Two bottles of mineral water (1.5 litres) and a beaker (for demonstration)
A bottle of mineral water (1.5 litres), a beaker and some cups (for pupils)
Procedures:
- Show two bottles of mineral water to the class and ask the pupils a question.
- Do they have the same volume? ( predicted answer: Yes.)
2. Then, pour a bottle of mineral water into a beaker and ask the pupils to compare
the beaker and the bottle of mineral water.
- Next, divide the class into groups of four students and have them work in their cooperative groups.
- Appoint a student in the group to be the recorder.
- Give each group a bottle of mineral water, a beaker and some cups.
- Ask the pupils to find out how many cups can a bottle of mineral water fills. This is done by pouring water from the bottle into the cups. The pupils have to write down the findings in the worksheet given.
- Repeat the same steps with the beaker.
- Have the pupils record their findings in the following table:
Container | Number of Cups |
A bottle of mineral water | |
A beaker |
- Discuss the misconception of height of containers and their capacity with the pupils.
- As a conclusion, the capacity of the bottle and the beaker are of the same volume although their water level looks different.
