This Kapow pupil video is part of the Kapow Science scheme of work . It is designed for pupils and introduces an investigation into the flow of different liquids by measuring how long each takes to travel down a laminated card. Pupils use a dropper to apply each liquid to the card, then time how quickly it flows from top to bottom, comparing substances such as water, honey, vinegar, cream, and oil.

Through repeated trials and careful recording of results, the video helps pupils explore the concept of viscosity—how thick or runny a liquid is—and understand how different liquids behave. It develops key working scientifically skills including observation, measurement, and data handling, while encouraging curiosity and experimentation.

The video is designed to be shown to pupils as part of Science, Lower key stage 2, Year 4, Making connections: How does the flow of liquids compare?, Lesson 2: Investigating liquids – Gathering data
