Turn on the heat lamp, adjust its intensity, and drag it closer to or
farther from the thermometer. Observe how light from the lamp transfers
energy and changes the temperature.

Turn on the lamp and drag it toward the thermometer.
Drag the lamp by clicking or touching its stand or shade.
Think about it:
How does moving the lamp closer affect the thermometer? How does changing
the lamp intensity affect the rate at which the temperature rises? What
evidence shows that energy moved from the lamp to the thermometer?
