An experiment was designed to investigate the effect of caffeine on the heartbeat of water fleas. Two populations of water fleas were cultured. Both populations had water with the same material content, were supplied with identical amounts of bacteria as food, received the same amount of light, and their temperature maintained at 20°C. Every two hours, water fleas from both populations were selected and their heartbeats monitored. The fleas of population A had caffeine administered five minutes before their heartbeat was checked.
