Some students investigated the effect of light intensity on the rate of photosynthesis. They used the apparatus shown in Figure 1.

Figure 1
The students:
- placed the lamp 10 cm from the pondweed
- counted the number of bubbles of gas released from the pondweed in 1 minute
- repeated this for different distances between the lamp and the pondweed.
The lamp gives out heat as well as light.

What could the students do to make sure that heat from the lamp did not affect the rate of photosynthesis?
