Today we were introduced to the upcoming experiment; The Paper Towel Lab. Tomorrow when we actually do the experiment, Mr. Sherman will show us how to do it first then he will split us into groups and let us do the experiment on our own.

Introduction to: the Paper Towel Lab and The Form of the Lab Report
Well first let me explain to you what the Paper Towel Lab is. It is when we test to see which brand of paper towels absorb the most water in a period of time, but the catch is we don't know which brand is which so people can't be like: Oh, I use this brand and I just love the way it feels so I'm going to choose this one to put in my hypothesis. We are keeping the paper towel in the water for a minute then take it out with the tongs, hold it there to let the water drip of of the paper towel into the beaker then pour the water that's in the beaker into a graduated cylinder to measure the amount of water that the paper towel didn't absorb then move on to the next brand. You have to do this three times with paper towels A, B, and C. For this experiment the independent variable is the brand of paper towels and the dependent variable is the amount of time in & the amount of water.
For the Lab Report page you have to use these categories and remember them:
purpose-Why are we doing this?
research-What does it look like?Feel?
procedures-How to do the experiment
results-What happened after/during the experiment?
conclusion-What is the main statement that comes from this experiment?
repeat the work-Do the experiment again to see if the data is accurate.
If you want a copy of the science Lab Report template it is on Blackboard under Science.
That's what we did today in science. if you have any questions, feel free to ask!!
