The Domino Effect 9-26-01 Abstract: In this experiment dominos were used to investigate how distance‚ time‚ and average speed is interrelated by maximizing the speed of falling dominoes. This was done by lining up 28 dominos up against a meter stick 0.5 cm‚ 1.0 cm‚ 1.5 cm‚ 2.0 cm‚ and 2.5 cm away from each other. Before the experiment the average width of a domino was taken. At the beginning of each of these 5 trials the dominos were lined up against the meter stick. The lengths of all the dominoes

The hypothesis for this experiment was that if the baby lemurs activity level was compared to an adults‚ the baby lemur will have a higher activity level. The hypothesis was not supported. The data shows that the adult had a higher activity level. The data shows the adult being 1.8% more active than the baby lemur. The other behaviors of the adult Ring Tailed Lemur was grooming and sleeping/resting. Second‚ throughout the six trials the only behaviors that were performed by the baby lemur was sleeping/resting

Glucose Oxidase and Its Various Uses Aaron Truong Since glucose oxidase has an end product called hydrogen peroxide‚ which is a harmful substance to bacteria‚ it can be used to fight bacteria‚ or sterilize objects (can have various uses such as in hand sanitizers‚ toothpaste‚ soap‚ etc)‚ not just biosensors. Another key part in the reaction would be C6H12O6‚ or glucose. Glucose oxidase can be applied to diabetics as mentioned earlier‚ as biosensors work by "keeping track of the

Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

Research Question Does the concentration of substrate (H2O2 (hydrogen peroxide)) have an effect on the activity of the enzyme (catalase)? Theory The higher the substrate concentration the more quickly product is produced (rate of reaction increases) until enzyme saturation is reached at which time more substrate has no further effect. Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all

The purpose of this experiment is to determine if the angle of impact affects the diameter and depth of a crater. The hypothesis was correct‚ stating that if the angle of impact changes than the depth and diameter will change due to the amount of speed and force is being put in the marble (meteor)‚ and the most effective angle for the diameter is at a 20 degree angle‚ and for depth is at a 90 degree angle. The hypothesis turned out to be true because it all depends to the angle the meteor or in this

of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction‚ because when the temperature is changed‚ the kinetic energy of the molecules

Introduction. The ’Stroop Effect ’ was first introduced in 1935. It originated from the theory of automatic processes. It is clear that some processing activities become automatic as a result of prolonged practice eg. Typing‚ driving‚ etc. Automatic processes therefore are fast‚ require no attention and are unavoidable. Stroop believed that there was some evidence that word identification may be a form of an automatic process. In the experiment participants had to name the colours in which the

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is
