is essential for human survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution.

Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers. The volunteers had replied to

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 paced

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

The Effects of 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

The Effects of Caffeine on the Heart Rate of Daphnia This lab was designed to show how caffeine affected the heart rate of daphnia after exposing them to different concentrations of caffeine for ten minutes. Caffeine is a stimulant‚ which‚ in humans‚ causes heart rates and blood pressure to increase. Its effects range from mild alertness to heightened anxiety and body tension. We wanted to see if caffeine affected the daphnia’s heart rate in the same way. We filled three containers with three different

Measuring the Effect of Light Intensity on Photosynthesis Introduction Photosynthesis captures energy from sunlight. Plants‚ algae‚ and some bacteria use the energy captured during photosynthesis for their metabolic reactions. During photosynthesis in plants‚ chlorophyll and enzymes in leaves convert certain wavelengths of light into chemical energy. A simple equation can be used to represent photosynthesis. Enzymes and Chlorophyll light energy CO2 H2O carbohydrate O2 In this investigation
