of Alcohol vs. Caffeine on Water Flea ’s Heart Rate. Title Page Abstract For our most recent experiment we tested the effects of immersing water fleas in caffeine and alcohol to see the effects on their heart rate. Before the experiment we hypothesized that if you place the water fleas in alcohol then their heart rate will slow down‚ and if you place them in caffeine then their heart rate will raise. For this experiment we needed water fleas‚ tap water‚ two pipettes‚ a microscope
