Year 6 Pump it Up: Modelling the Human Heart! 🫀

This half-term, our budding scientists are diving deep into the circulatory system! We kicked things off this week by getting hands-on with the body's most tireless engine: the heart.

To understand how this incredible organ functions, our pupils didn't just look at diagrams — they became engineers.

Using modelling dough we sculpted hearts, carefully layering the chambers and rolling out dough "tubes" to represent the vital entrance and exit points for blood flow.

To see the mechanics in action, we transformed everyday items into a working cardiovascular model:

The Jar: Our "Heart" filled with red-tinted water (blood). The Balloon: Acting as the strong "Muscle Walls." The Straws: The "Blood Vessels" that transport life-giving fluid.  By sealing one "valve" and pushing down on the balloon, pupils witnessed exactly how pressure forces blood out of the heart and through the body. It was a messy, marvellous way to see biology in motion!
