Test method

The experiment was conducted to test the effectiveness of one’s ability to balance and walk on a 2x4 platform that is approximately 332cm or 11ft long, while blindfolded. It is known that vision impairment is associated with poor balance. We predicted that the subjects that were blindfolded will have poor balance and will not be able to walk very far on the 2x4 platform. In this experiment we had a total of eight (8) test subjects. First we allowed 4 individuals to walk the 2x4 without a…

Module 2 Assignment – SBI4U-TK Purpose: To observe the power of aerobic exercise compared to the power of anaerobic exercise, and how much glucose does exercise consume. Predictions: (a) Predict hoe many times more powerful aerobic exercise is than anaerobic exercise? = Triple (b) Predict how many teaspoons of table sugar you will “burn” after exercising your arm to exhaustion. =5 Materials: 2.2 kg Dumbbell, Meter Stick Procedure: Please refer to the Nelson Biology 12 textbook page 128.…

In Witt, J. K., & Proffitt, D. R. (2005), the experiments assess whether the influence of effort on distance perception is generally or functionally specific. In the first three experiments, the effort for throwing was manipulated by having half of the participants throw a heavy ball and the other half throw a light ball. It was found that effort for throwing influenced verbal reports of distance as well as perceptual distance - matching tasks, but, effort for throwing did not influence…

The purpose of this lab was to determine if a change in mass occurs during a chemical reaction in a closed system. To conduct this experiment, the mass of the test tube, rubber cover, and other materials must be measured. To prevent the test tube from rolling off of the balance, a plastic cup was used to hold it in place, but the group had to remember to zero out the cup on the balance so the cup’s mass will not affect the masses of the objects the group was trying to measure. During this…

Egg Drop Experiment My Plan was a very simple but complicated task. My plan was to make one small triangular prism. I did this out of transparent tape (scotch tape), duct tape, and straws. First I made a small triangle that held the egg snug for maximum protection. Then I taped straws to every side of the triangle. But I tested it and it wasn’t enough off the roof of my house. So, what did I do? I reinforced the straws and made it into triple straws for more suspension. Before I dropped I was…

After testing the D. magna with alcohol, the results showed a negative effect on the D. magna. After recording the normal heart rate in beats per minute (bpm) before the experiment, alcohol was applied to four different D. magna for each percentage of alcohol. The three concentrations of alcohol used were 5%, 10%, and 20%. Once the differences in heart rate were recorded for each of the D. magna, the averages of the four differences in heart rate for each concentration of alcohol were calculated…

Experimental Procedures Identification Procedures Sight/Smell Test Used the scale to obtain 0.5 g of each of the known substances and placed into their own cell in the microscale wells (being sure to label each cell with the proper substance). Used the eyes and the nose to compare the physical characteristics of the unknown substance with all of the known substances in the microscale wells (visual appearance and scent). Narrowed down the known substances (keeping the substances that look…

Start the testing procedure by pressing start button on the tunnel frequency control by pressing up and down buttons and increase rpm until the free stream velocity in the test section of the wind tunnel reaches 100 ft/s. For the free stream velocity to reach 100 ft/s, the rpm setting of the frequency control should be approximately 1100 rpm. Please be aware that the rpm setting for this experiment should never exceed 1500…

This paper describes an experiment to determine the height of the Flagpole in front of Waterloo Collegiate Institute, a high school in Waterloo, Ontario, Canada. During the experiment, we approach the task with similar triangles and their properties. Being that, we created two similar right triangles with the flagpole as one of the legs of one triangle and my partner as one of the legs of the other. Due to the fact that similar triangles are proportional in terms of side lengths, we measure the…

Procedures How was the experiment carried out to answer the problem? Day 1 - Determining Flight Factors On the first day we discussed as a class what variables could affect the flight path of the balloon. This list included anything from the placement of the balloon in the slingshot to an innocent bird flying by while the balloon is in the air. Each factor was then sorted into a category of either a control variable or an act of god. From the list of control factors, we selected the mass of…
