Investigating Speed's Relationship to Size and Shape

Aim

I am investigating if the speed of an object changes when the size or

shape is changed.

I will investigate this through 2 experiments.

Apparatus list

Stopwatch

20 pieces of tracing paper

Scales

Preliminary work

Before my main experiment, I decided to do some practices to determine

how high to drop the paper from. I started at 1m and noticed

immediately that the time it took to reach the ground was too quick

for us to take a reading in. I decided to increase the height by 1m.

When I dropped the paper from 2m, I was able to take an accurate

reading and decided to increase the height again by 1m. I then

encountered a problem being that it was too dangerous to drop the

paper from this height, so I chose to drop the paper from a height of

2m.

Plan

Experiment 1: An A4 piece of paper will be dropped from a height of

2m, 3 times. When the paper is released, a stopwatch will be used to

time how long it takes to reach the floor, and this will be recorded

in a table. The average of the three results will be found and the

speed will be calculated. The paper will then be halved to A5 size and

the above will be repeated. I will then fold the paper and repeat the

experiment as many times as possible. 2.389g

Prediction

I predict that as the size of the paper decreases, the time taken for

the paper to reach the ground also decreases. I think this because as

the size of paper decreases, the surface area exposed to Upthrust also

decreases. Gravity stays the same throughout the experiment because

the mass of the object never changes, but Upthrust does change. This

results in gravity being more dominant on an A5 piece of paper than an

A4 piece of paper, resulting in the time taken for the A5 piece of

## Investigating the Rate of Reaction Between Marble Chips and the Varying Concentrations of Hydrochloric Acid

Investigating the Rate of Reaction Between Marble Chips and the Varying Concentrations of Hydrochloric Acid Planning Before starting the experiment I had to work out how much marble chips would be needed and how much HCl would be needed. I decided that 20 grams of marble chips would be needed and I measured this on a pan balance. The chips would have to be of medium size as from a previous experiment done in class I realize that changing the surface area of the marble chips would change the rate of reaction. I then used 100 cm3 of HCl and this would be the only variable that I will change. I decided to use the concentrations of 0.5M, 1.0M, 1.5M and 2.0M (1mole/dm).

I then left each test for 20 minutes, but found after that time a slight reaction had taken place - the potato chips only increased or decreased by a very short amount. I then predicted that now I would have to leave the tests for a longer amount of time and use longer potato chips to ensure that there is enough of a reaction to compare

People at very high risk for diabetes reduced their risk with lifestyle intervention. The goal is to try to lose 7% of initial weight and increase activity levels to 150 min more per week than current physical activity. This study showed that the risk of diabetes could be decrease with this lifestyle intervention by 58%. They could change their environmental factors from genetic factors taking the weight and the activity out of the equation. Also, a 10-20 pounds loss is enough to improve diabetes.

## The Importance Of Cardiovascular Exercise

(See Reference 1) Calorie-Blasting Cardiovascular Exercise Cardiovascular exercise makes you breathe harder and increases your body temperature, resulting in caloric burn. To lose weight, the U.S. department of Health and Human Services recommends doing at least 150 minutes of moderate cardio a week, and if needed, slowly working your way up to 300 minutes of cardio. (See References 2) In 30 minutes, a 150-pound person can burn 335 calories by pedaling on an elliptical machine; 223 calories on a stair climber; and 372 calories by running at a speed of 6 mph, playing racquetball, or by jumping rope.

This was intended to emulate cognitive load; fast speed was high cognitive load, and slow speed was low cognitive load. After the 20 seconds, participants were asked to state their answer; how frequently the target digit appeared in the trail. Two second later, another trial for digit series was presented. Then randomly between 50 to 75% of series trials, the trait test was presented replacing the target digit task for 500ms interval. The series digit task then continued simultaneously with the

## The Change in Resistance of a Carbon Paper

Starting fires, turning on the radiator, opening windows, etc). We will change the width of the paper for each experiment by simply cutting off 1cm horizontally for each experiment, so it will go 4cm, 3cm, etc. We will do this accurately and carefully with a ruler and scissors, to ensure accuracy, Prediction I predict that as the width decreases, the resistance will increase, and as the width increases, the resistance will decrease. I predict this because if the paper has a large width, there will be more room for the current to flow through, and so the resistance will be less, whereas if the paper is thinner, there will be less room, and the resistance will increase. I also predict ... ... middle of paper ... ...ted to be really accurate) doing each width 5 times, and we also could have done more widths, perhaps doing an experiment every 1/2cm instead of whole cm.

## Investigating Factors that Affect the Swinging Of a Pendulum

Experiment 1 I will investigate the relationship between the length of the string, and the time it takes for the pendulum to make 1 full swing. Ã˜ Hypothesis: As the length of the string increases, so does the time. Ã˜ Procedure: We will test how long it takes for a 80g weight attached to a string to swing from one point and back to the same point. We will use various lengths of string to test the times of the swing. However, I will measure the time taken for 10 oscillations rather that 1 and then divide the result by 10, in order to eliminate as much time and reaction error as possible.

The authors used the mean as the central tendency which seems appropriate because logically people who weigh different amounts are going to lose weight proportionally. There is also a level of thoroughness that is evident by preforming the statistical analysis at multiple intervals. Had the authors only compared baseline to 12 months they could have missed a trend such as the change in total cholesterol. There was a decrease in total cholesterol at 3 and 6 months but by 12 months it was almost similar to baseline. h. Evaluate the discussion of results and the conclusions of the study.
