Heart Pump Lab
The heart is a pump: each muscle squeeze raises pressure, one-way valves direct that pressure into forward blood flow, and body demand changes how quickly the pump repeats.

What your child will figure out
- Predict and explain how a heart-muscle squeeze raises pressure and moves blood already inside the chambers.
- Use visible backflow to explain why heart valves must close in one direction.
- Match heart rate to body demand and reason about flow per minute.
- Transfer pressure, valve, and rate reasoning to generated combinations in adaptive practice.
The levels
- Wake the pump
Predict, pump, observe, and explain the squeeze-to-pressure-to-flow chain.
- Valve trouble
Reveal backflow with a stuck-open valve and explain the valve's one-way job.
- Power up
Relate exercise demand to more beats and more flow in the same minute.
- Bus-stop sprint
Transfer demand-to-rate reasoning from the lab to sleep versus sprinting.
