Daphnia Ecotoxicology Lab Report
Ecosystems have a way of maintaining themselves under ordinary conditions but when a new factor is added that will most likely threaten the environment action needs to be put forth. Our environment is affected by many p
Investigating the effect of coffee on the heart rate of daphnia
To find out the effect of different caffeine concentrations on heart rate in daphnia
• Caffeine concentration
• Daphnia heart rate
• Size of daphnia
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
TITLE: Effect of the caffeine on the heart rate
OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms.
Daphnia are small, planktonic crustaceans, between 0.2 and 5 mm in length. Daphnia are members of the

Aspect 1: Defining the problem and selecting variables
In this lab, we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate, such as exercise, drinking coffee, taking certain pills, drinking an energy drink, feeling a s
AP Biology Lab: Catalase (Enzymes)
In this laboratory exercise, studies of enzyme catalase, which accelerates the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. The lab
The affect of psychological stress on the heart rate.
The human body is incredible machinery that can adjust to stressful situations and react in a “fight-or flight” manner by temporarily shutting off nonessential, at the moment, immune and digestive systems. When the body i
