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

The effects of Visual Distraction on Reaction Time Abstract Distraction has been associated with affecting human reaction time. These associations have been obtained from studies focusing on drivers in particular. Driver distraction is very common nowadays and it is associated with many car crashes (Governors Highway Safety Association‚ 2011). Distraction can take forms in visual‚ cognitive‚ auditory and manual handling of the vehicle. In this study the aim was to test the effects of visual

How Enzyme Concentration can Affect Rate of Reaction The purpose of this investigation was to see how the concentration of an enzyme affected the rate at which a substance was broken down. We did this by using a white protein called casein. Casein is found in milk powder‚ it is a protein and used mainly as a binding agent in foods‚ because it is mad to proteins and joins to a phosphoric acid it belong to a group called the phophoproteins. In terms of in milk it is said to be healthier if it is

Effect Of A Sport Drink On Reaction Time Abstract Doing heavy sport such as run marathon or exercise in the gym can produce much sweat. Produce too much sweat could have a significant loss of fluid and electrolytes in the body such as potassium and calcium. This can cause symptoms from fatigue and reduction in exercise performance to more serious conditions such as heat exhaustion or heat stroke (Leong‚ 2007). Drinking water after exercise helps to restore water balance in the body. Drinking

gravity and the type of surface was tested through a series of experiments. In lab 4.1‚ the force of gravity was tested through various surface types‚ including: tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sand paper. In lab 4.2‚ two different surface types that were tested included: tabletop and coarse sand paper. This lab compared the two averages between both tabletop and coarse sandpaper using different amounts of blocks. In lab 4.3‚ the surface area of the blocks sliding across

An investigation to show how the rate of reaction between hydrochloric acid and sodium thiosulphate is affected by the concentration of the acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate‚ and record the amount of time taken for the cross to disappear through the solution from the top of the flask. Record this time and repeat this for different concentrations of hydrochloric acid. Fair Test The variables in

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min and
