Must two bodies settle at the simple average of their temperatures?
Mapping provisionalOpen investigation →Open a chapter to see its learning path and the availability of every experience.
Investigate a continuous conducting path and the role of a switch.
Connect leaf structures, gas exchange and photosynthesis through original educational models.
Measure distance and time, compare speeds and connect a moving object with a graph.
Investigate ventilation, gas exchange and the pumping role in transport through bounded original process boards.
What must be connected for the bulb to light?
Connect the components, close the switch and investigate a continuous electrical path.
How does air reach the living cells inside a leaf?
Turn a leaf, inspect its surface and open its layers to connect structure with gas exchange.
Why can more light stop increasing this model's photosynthesis rate?
Change relative light and carbon dioxide availability, then explain a plateau in a disclosed rate model.
How does a change in velocity change position over time?
Move between a position, a measurement and a graph while changing one parameter at a time.
How does changing diaphragm movement affect fresh-air entry, and when does chest motion fail to tell the full story?
Control a chest model, compare fair trials and trace two gases before explaining where energy is released.
What does pumping change, and why is blood not used up when it delivers oxygen?
Construct a loop, follow the same blood courier and compare pumping with no pumping while oxygen cargo is exchanged.

Current body re-inspected for breathing mechanism, alveolar exchange, respiration distinction and generic heart/blood/vessel transport. The original four-station transport loop is explanatory enrichment; named chambers and vessel types are not required VII objectives here.
