PROBLEM Does the Quilted Northern, Angel Soft, Members Mark, Cottonelle, Scott, or Charmin brand of toilet paper break apart the fastest in moving water? Does the brand Quilted Northern, Angel Soft, Members Mark, Cottonelle, Scott, or Charmin when wet hold the most pennies? Does the brand Quilted Northern, Angel Soft, Members Mark, Cottonelle, Scott, or Charmin hold the most pennies when dry?

HYPOTHESIS My hypothesis is that Scott will break apart the fastest in moving water because Scott is one-ply and the thinnest of all the toilet paper.
My second hypothesis is that Quilted Northern will hold the most pennies when wet because it is one of the thickest toilet papers.
My third hypothesis is that the Member’s Mark will hold the most pennies when it is dry because Member’s Mark is two-ply and appears the thickest.

PROCEDURE To prepare for both experiments I will acquire five brands of toilet paper, rubber bands, and a stopwatch from local stores. There is no control group for any of the experiments because I am comparing brands of toilet paper. The variable for each experiment will be the brand of toilet paper otherwise, for each experiment everything else will be …show more content…

I measure one cup of tap water in a two-cup measuring cup. I will then use a mixer to move the water at medium speed (three). The mixer will not touch the bottom and will be steadied by placing it on a platform. I will then drop a square of toilet paper in the moving water while starting a stopwatch. I will time it until it breaks apart into small pieces. The time will be converted into seconds. I will repeat this twenty times for each brand. I will take the average of each brand and create a bar graph. The seconds will be one the y-axis and the brand one the x-axis. For each brand, I will create a bar graph to show the results, with seconds on the y-axis and trial on the

Next, we determined the mass of the penny by placing it on a balance. The mass of the penny was 2.47 grams. Afterwards, we placed the penny in a beaker filled with 20 mL of 6 M HCl. In the end we put the beaker in the fume hood and allowed it to sit overnight. During day two of the penny lab, we removed the penny skin from the beaker using tweezers.

My first hypothesis is if I put a quarter in a graduated cylinder and get the volume and weigh it, then it will have the greatest density. If I put a dime in a graduated cylinder and get the volume and weigh it, then it’s density will be between the quarter and the penny. And finally, if I put a penny in a graduated cylinder and get the volume and weigh it, then it will have the lowest density out of the three coins.

In conclusion, the dime was able to pull it off and hold more drops than the penny. My hypothesis was incorrect because, I thought the penny would hold more drops than the dime because the penny was bigger and I thought it would absorb more. But the dime held more. Preston and I even ran the tests or investigation three times for each coin. The one question I had was ,what if the penny was stacked 1 time and the dime was stacked one time,would it make a difference ?

How does the type of dissolvent in the water affect the number of drops that can fit on a penny? We will attempt to find the answer to this question using the hypothesis “If we use salt water solution, then there will be more drops on the penny. ” We will use the materials salt, sugar, lemonade mix, flour, a beaker, a pipette, paper towels, a stirring rod, a graduated cylinder, and some tap

On our paper we predicted the amount of pennies that could fit in the boat before it sank. We tested the boat in the water and added pennies one by one. We then calculated the mass of pennies that fit in the boat and the density of it. The purpose of this Lab was to make a boat that holds as many pennies as possible and understand how to calculate

The purpose of this lab was to find out what the strongest tissue of the three brands my group tested. My group 's hypothesis w.as, if different amounts of weight is put on three different brands of tissues, then the Kleenex will stay the strongest, because this brand is more advertised. The experiment concluded that Up & Up was the strongest at 28 pennies, Kleenex was the second strongest at 9 1/2 pennies, while Darnix came in last place at 5 pennies.

I would get 200 random men and women combined to be the participants for this study. I would get about 500 polo shirts for them to choose from. I would use two studies for this experiment. The first study would be on just the color of the shirt. The second study would be on the design of the shirt.

On Tuesday in lab, we were first asked to brainstorm ideas for clocks. Some of the things we thought of that could be used as a clock were a simple pendulum, sun dial, your pulse, and drips from a leaky faucet. Then, we spent the rest of our time testing out the drippy faucet idea by poking a hole in the bottom of a cup, placing it above a graduated cylinder, filling it with water, and timing how long it took for the drips to fill up 10mL. While the hole was dripping out water, we had to continually put more water in the cup so that the pressure was consistent throughout the entire experiment. If we did not do this, the water could drip faster or slower depending on how much water was in the cup. We tested the amount of time it took to get

The purpose of conducting this experiment was to find out which brand of cake mix rises the highest, when it is fully cooked. The hypothesis was, “If cake mix can rise, then the Betty Crocker Brand will rise the highest.” The independent variable was the different brands of vanilla cake mix. The dependent variable was the rise in height of the fully cooked cake. The way that the data was measured was by taking a ruler, and the cake, and measuring the whole cake, from bottom to top.

It is extremely important for us to make sure that our test subjects give their full permission and know what they are being used for. Ethics allow things to run smoothly and if we did not rely on them, our procedures would be much more chaotic. In chapter four, I took the time to really identify the differences and similarities between the independent and dependent variable in an experiment. Variables are something that is changing in an experiment and they are usually are a factor or trait that comes in different amounts.

This experiment would take place over the course of a week, and would be conducted at 8:15 a.m., 12:15 pm, and 4:15 p.m. to allow for more generalizable results. A female confederate would be sitting at a community table at the West Mall Starbucks, and would appear to be studying. The female confederate would either be wearing a SFU hoodie and have a SFU backpack, as well as a SFU notebook and pen, or they would be wearing descriptive clothing, backpack, and accessories. The female confederate would “accidentally” spill water over their notes, while two observers would watch whether anyone helped. Helping behaviour would be measured through the number of people who get napkins for the female confederate or use napkins to help dry out the pages.
