In this project, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine on heart rate. Don't worry about having to learn how to take a crustacean's pulse: you can actually see the heart beating under a microscope. Many variations of this experiment are possible. Read more

Time Required Average (6-10 days)
Prerequisites You will need a microscope for observing Daphnia closely enough to monitor heart rate. Either a dissecting microscope or a compound microscope with low-power objective and a depression slide could be used.

Caffeine is a type of chemical called a stimulant. When you drink a caffeinated beverage, the caffeine enters into your blood stream dilating the capillaries and causing blood to flow more quickly. This gives your body a feeling of speeding up which can cause the jitters and wakefulness. How does caffeine affect the physiology of other animals? You can use over-the-counter caffeine supplements, like Vivarin, to test the effects of caffeine on animals. Try dissolving the caffeine in… Read more

Animals come in all shapes and sizes, even humans. You can look up different statistics about different kinds of animals using the Internet: average body size, brain size, life expectancy and generation time are some examples. Is there a correlation between body size and life span? Is there a correlation between body size and brain size? Is there a correlation between body size and generation time? Is there a correlation between body size and the size of your footprint? (Comparative Mammalian… Read more

Have you ever stopped to watch a trail of ants moving back and forth between a food source and their nest? Have you ever wondered how they establish their trail? You've probably read that ants use chemical signals to communicate with one another. This is a relatively simple experiment that you can do to determine whether ants use attractant signals (positive cues) or repellant signals (negative cues) or both. Read more

One thing that all living things have in common is that they grow through cell division. How is this growth regulated? Sometimes growth occurs when it is not supposed to, leading to cancer. Scientists are trying to discover how growth is regulated, hoping to find potential cures for cancer. One idea is that cells keep track of growth using special regions of the chromosome called "telomeres" that count how many divisions a cell has made. If this is true, then growth, cell division and age are… Read more

You've probably heard about differences between the left brain and the right brain in people. Did you ever wonder where that came from? Do other animals have specialized brain hemispheres too? One hypothesis has it that brain lateralization evolved as a survival mechanism in animals with eyes on the sides of their heads. One eye could focus on finding food, while the other watched out for predators. This project tests that hypothesis by looking for left-right bias in feeding behavior in lizards. Read more
