Take some germinating seeds in a Thermos flask.

Cover the flask with a cork.

Insert the thermometer in the flask through the cork.

Observe the rise in temperature after some time.

As the seeds respire, heat will be produced due to release of carbon dioxide. Thus, the temperature in the thermometer will rise.

PRECAUTIONS:

Thermos flask should be properly sealed so that no air enter it.

Thermometer should be properly inserted else it will break.

Leave the apparatus undisturbed for proper time as seeds will respire.
