Paper Towel Lab

Title

An experiment into which paper towel absorb the most water

Problem

Our purpose is to find out which of the 2 brands of paper towels absorb the most water.

Hypothesis:

If we squirt died water on Bounty Basic paper towels and CDNIS paper towels that are set on top of a sheet of paper then more will go through the CDNIS paper towel because the Bounty Basic has lots of crevices and the material that Bounty Basic is made out of is thicker.

Independent Variable

Brand of paper towel.

Dependent Variable

How much water goes through the paper towel?

Control Variable

How much water

How long it takes to squirt the water

How we measure it

How many sheets of paper

The time of letting the paper towels absorb

Using the same string

Not stretching the string when measuring

Squirting the water from the same height

The type of paper Used

 

Materials

Paper  6 sheets

Died water 5.25ml

Pipette 1

String 1 about 20 cm

Timer 1

Paper towel 6

Bucket 1

Ruler 1

 

Method:

First you have to set either a CDNIS paper towel or a Bounty Basic paper towel on top of a sheet of paper in a bucket. Secondly you need suck 0.75 ml of died water into a pipette. 3rd squirt the water that was in the pipette on to the paper towel from 3 cm above. 4th 5 seconds from the time that the pipette hit the paper take the paper towel off the sheet of paper. 5th measure the circumference of the stain on the piece of paper with string. 6th convert the circumference into area. 7th Repeat three times per brand of paper towel

 

ChartData Collection Table: For the amount of water that leaked through the different brands of paper towels

Test # Bounty Basic (cm) CDNIS paper towels (cm)
1 14.28 35.09
2 14.28 38.51
3 14.5 28.72

 

Evaluation:

I followed the method the whole time except except  a couple of times there were errors like I didn’t squirt the water from the same height or angle which effected the data so I counted the test inconclusive and redid it. This investigation has proven that our Hypothesis was correct because we thought that the Bounty Basic would absorb more water then the CDNIS paper towels because Bounty Basic paper towels are thicker and our experiment showed our hypothesis was correct because in the graph you can see how more then double the amount of water is going through the CDNIS paper towels then is going through Bounty Basic. In this investigation I think we had a couple errors that could have ben fixed by us and some that we would need special tools to fix. The errors that we could have fixed were making sure that we squirted the from the same hight. We could have also used a lot less paper by cutting the paper in half instead of using a hole sheet every time. The errors that we need better tools to fix are using a tool that could help measure the amount of water that got through the paper towels instead of using string. Also even with the pipette it was hard to keep our fingers steady enough to hold the pipette at the right amount so it would have ben more accurate if we had better tools for that also.

 

 

Conclusion:

In conclusion my chart has shown that on average Bounty Basic absorbs double the amount of water that the CDNIS paper towels absorb. I think that this has happened because Bounty Basic is a lot thicker then CDNIS paper towels and has lots of crevices that water can get stuck in.

Soccer PE Unit reflection

During this unit the main thing that I learned is space= time. Because if you are further away from the defender then it will take him a longer amount of time to get to you. Fore example if you were playing a monkey in the middle game everyone would go far away as tey can because that way the person in the middle wont be able to get the ball. Also I learned a very good strategy/ game plan which was diamond one man attacking to in the middle and one in defense.

I liked how every thing that we learned Mr. Short showed us how to use it in a game strategy rather then just telling us because that way it was easier to learn and easier to remember.

 

Monologue Summative Script

My whole life has been so hard. My parents don’t even want me to come home. It’s been such a mess. Growing up on the street. Being arrested when I was 8, stealing just to survive. You have no idea what it’s like.

But some some how,pause some how I found a way to slowly push through all of that trash. And now after this happened, is there even a reason to live and keep going when I know that even more baloney will keep happening to me?

 

Johnny pause the only person who ever gave a dime about me is gone. that little innocent puppy;eyed kid. little Johnny cake. The only person who I could talk too. I was is role middle thats probably why he is dead only if he looked up to some one like Darry maybe then he wouldn’t have died. And now the group is going to fall apart, Johnny was the one who kept the group united. But now he’s gone pause all gone forever. And now  cause he’s gone theres not one dang person  on this planet who gives a dime what happens to me.

 

Maybe I should just stop and give up on my life. Because so far the only good things in my life have disappeared. So I should just end this, right now. end this baloney of a life. The only question is how Pause how can I take my own life but still be a tough greaser and not make the socs think that I am weak and they pressured me into this? because they are better then me and that I would rather die then to keep fighting with the socs. Because thats not why I’m ending my life. or is it? Is it because they have done everything possible to make me and all greasers life’s terrible? No I’m doing this because of my parents, my past, and because johnny is dead. Not because of the socs.

English Summative On Outsiders

There are a couple reasons why Pony Boy told himself he was the one who killed Bob. I think that Pony Boy insisted that he was the one who killed Bob because then he wouldn’t have to keep thinking about how Johnny had saved Pony’s life by killing Bob, and reminding himself that Johnny was dead also one of the main reasons why Johnny was at the church was because he was on the run from the police for saving Pony Boys life. Also Pony Boy probably feels better knowing that his friend who just died was not a murderer. In conclusion Pony Boy is insisting that he killed Johnny because that way he will not have to think about Johnny or remember that his friend killed another human being instead of the really good friend that he had ben.

Environment and Human Ingenuit

In the Lorax Environment and Human Ingenuity come into conflict because  Human Ingenuity uses the environment to create objects that we need which then become garbage and pollute the environment. The problem with that is Environment has limited resources just like inn the Lorax where they run out of trees in the end. Also it all becomes garbage eventually for example the lake in the Lorax got so polluted that the humming fish couldn’t even live in it any more. I think that the man made beach shouldn’t happen because there is so much natural life that will die. And The human ingenuity which is making the beach isn’t worth killing so much wildlife. That is why I think that they should make a beac where there is not wildlife that they would kill, so i think that Environment is the more important aspect in this scenario.
