Mass and capacity - Measure capacity 2 - Presentation

In today's lesson, students will delve deeper into the concept of measuring capacity, enhancing their understanding and distinguishing between capacity and volume. The session begins with a discussion that recaps the differences between these two measurements, setting the stage for a series of engaging activities. Students will use practical equipment and liquids to measure in 100 ml increments, observing the transition as the volume reaches 1,000 ml, equivalent to 1 litre. They will explore related conversions, such as understanding that 2 litres equate to 2,000 millilitres. This hands-on approach not only reinforces the metric system but also encourages students to make connections between different units of measurement.

The lesson includes a series of interactive activities where students must identify and fill in missing information based on the capacity of different containers. They will engage with scales and measurements, determining the capacity of objects like pots and barrels in both litres and millilitres. For example, they might be tasked with calculating how much liquid remains in a container after a certain amount is removed, such as figuring out the remaining water in a fishbowl after 5 litres have been poured out. These exercises are designed to strengthen their reasoning skills and to help them visualise and understand the practical applications of measuring capacity. Additionally, the lesson tackles misconceptions and challenges students to consider whether the tallest container necessarily has the largest capacity, thereby reinforcing that capacity is influenced by both height and width.
