is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

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. The question

Hypothesis: As the caffeine concentration rises‚ so does the mean heart rate of daphnia. Risk Assessment: In this experiment there are the following risks both for the human that carries out the experiment and the daphnia: ← The human that carries out the experiment should be cautious not to touch the lamp with wet hands since it uses electricity. ← Also‚ be careful not to spill any of the pond water on the floor. ← As for the daphnia‚ there is a chance for them to die as when

and it helps ensure the survival of an organism. It does so by converting things like food that we ingest into energy via a series of somewhat complex biochemical reactions. This energy can then be used for a multitude of things including growth‚ blood circulation‚ body movement‚ etc. When this energy is used O2 consumption and CO2 production are necessary due to O2 being our terminal electron acceptor. With that being said‚ metabolism is not a set characteristic within the human body. It can be

The effect of exercise on heart rate Word Count THE EFFECT OF EXERCISE ON HEART RATE Abstract - Aims - This study is to ascertain‚ if there is an effect on heart rate after exercise. This is being done to see‚ if there is a difference between resting heart rate and heart rate after performing exercise. Method and results - The study was compiled of seven female students from the University of Huddersfield. For the exercise a step was used‚ a polar heart rate monitor was used for each

An RER of 0.7 means that carbohydrates are being used for fuel‚ and a ratio of 1.0 means that only fatty acids are being used for fuel; of course‚ values can fall between. Methods: To observe the effects of prolonged exercise on the metabolic system the lab subject needed to walk on the treadmill at a rate that kept his heart rate at 60% of his maximum. The
