During today’s science experiment, Year 6 explored how restricted arteries can affect the human body. The children carried out an investigation using cups with different sized holes to model how blood flows through arteries. They poured water into each cup and timed how quickly it passed through, recording their results and comparing the differences. The cups with smaller holes represented restricted or clogged arteries, showing how blockages can slow down or even prevent the flow altogether. This hands on activity helped the children clearly visualise the impact of unhealthy arteries and deepen their understanding of the circulatory system.
