The popular name for Daphnia is ‘water fleas’ because they resemble fleas in shape and movement. Unlike fleas‚ which are insects‚ Daphnia are crustaceans classified under the scientific order‚ Cladocera. The purpose of this experiment was to examine the alertness of Daphnia ambigua alertness at different temperatures. It involved the incubation of 30 Daphnia ambigua in three 100ml beakers. Exposing each beaker to a different temperature revealed that temperature of the surrounding environment had

music affect the heart rate and what different types of music have a greater affect on heart rate? Music most definitely has emotional value. Heart rate can be directly influenced by these emotional changes. Our group decided to test music tempo’s effect on heart rate. This experiment is relevant to one’s health because it is important to understand how to control one’s heart rate. Before we started conducting our experiment‚ we hypothesized that fast tempo music increases heart rates while slower

An Investigation To See The Effect That Alcohol Has Upon The Heart Rate Of Daphnia. Aim: In this investigation I am going to see how alcohol affects the heart. Due to the ethical and safety issues involved in using in an investigation such as this I am going to use Daphnia (water flea) to conduct this experiment. Although humans and Daphnia are very different organisms‚ the affect that alcohol has upon the heart should be similar. Hypothesis: The hypothesis I am going to test during the

COFFEE USE - HEART RATE RESEARCH PROJECT COFFEE USE - HEART RATE Part 1 The study used for this project is a nursing and health sciences study. One particular healthcare facility is trying to determine if it is a good idea to provide coffee in the waiting room for the patients. There are several other facilities that serve tea‚ coffee‚ and water‚ so this health care facility wants to determine if there is sufficient evidence to show that coffee increases the patient heart rates.

Investigate the effect of on exercise on the heart rate. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Equipment needed: Stop watch Screen volunteer P.E kit Calculator Record sheet Type of exercise: skip for few minutes ‚ then break in between and again repeat it once or twice. Method: First of all‚ we needed to take the resting heart rate of the person who is about to skip. Then‚ with the stopwatch one

Aerobic Exercise on Heart Rate Introduction: Our bodies need to be in balance in order to function properly‚ and there are many ways the body maintains balance‚ or homeostasis. Homeostasis is the maintenance of nearly constant conditions in the internal environment. Our normal heart rate is an example of our body in homeostasis and any sort of change‚ or stimulus‚ can alter it. Exercise‚ adrenaline in the blood‚ and a low blood pH are all stimuli that increase the heart rate. Exercise‚ for example
