Variables to consider:
Dependent Variable:
The amount of water put in each beaker
Independent variable:
The amount of toilet paper used
Controlled Variable:
The amount of time the toilet paper is left in the container
Equipment:
4 different brands of toilet paper, 4 containers, water, measuring cup, tweezers
Hypothesis:
The more expensive brand of toilet paper will absorb more water than the cheap brand of toilet paper in a short amount of time
Aim:
To determine whether the expensive brand of toilet paper or the cheap brand of toilet paper absorbs the most water in a short amount of time
One method that can be used:
1. Put all the equipment listed on a table
2. Pour 20mL of water into each container
3. Tear off one square piece of toilet paper, making sure each has the same area
4. Put each square into a separate beaker at the same time
5. Record which toilet paper brand was put into which container
6. Leave toilet paper in for one minute
7. Use tweezers to pull out each toilet paper at one minute
8. Measure and record how much water is left in each beaker with a measuring cup
9. Repeat steps 3-8 three more times, this time using 50mL of water, 70mL of water and 90mL of water

I'm a little bit hesitant to approve your project. Mainly because it is such an easy project to do that I would have expected this from a year 5 or 6 student.
ReplyDeleteHow are you planning to make it a year 10 level project? You'll need to work a little more on this and come back to me when you can make it more your level.
