Mass, Capacity, Temperature - Measure capacity - Presentation

In a practical and engaging lesson on measuring capacity, students are encouraged to explore the volume of various containers using hands-on activities. The primary goal is to understand how to measure the amount of liquid a container can hold. Students are posed with thought-provoking questions such as how to determine the capacity of a large jug and what tools might be used for such measurements. The lesson involves interactive discussions and practical exercises where students use smaller containers to measure and fill larger ones, thereby gaining a concrete understanding of capacity.

The activities are structured to help students visualise and quantify capacity. For example, they may be asked to predict and then measure how many cups are needed to fill a bucket, and then extend this to two, three, or four buckets, identifying patterns as they go. This methodical approach helps reinforce the concept of volume and its measurement. The lesson also includes reasoning tasks where students must evaluate the accuracy of measurements, such as determining if a bottle's capacity is correctly stated based on the number of cups used to fill it. To consolidate their understanding, students complete independent work, filling in the blanks to express the capacity of various containers in units of small glasses, cups, or bowls, and discussing the results, which fosters critical thinking about measurement and comparison.
