At what speed do different materials sink or float on water?
Hypothesis:
Procedures:
- Gather your materials.
- Create a data chart.
- Pour 4 gallons of water into a 5 gallon bucket.
- Make boats out of paper, plastic, legos, and wood.
- Put 1 boat on the water.
- Put one of the weights on the boats.
- Time it till it sinks.
- Repat 5-7 15 times.
- Record your results.
Background Information:
Clay:
William Harbutt invented modeling clay in 1897. The ingredients in modeling clay is peanuts & legumes, tree nuts, eggs & egg shell, milk, casein, nut & nut shell, red dye, and latex.
Paper:
The main ingredient of paper is plant material.
Rocks:
A rock is made out of 2 or more minerals.
Legos:
Legos are made from acrylonitrile, butadiene, and styrene. Ole Kirk Christiansen invented Legos.
Paper clips:
Paper clips are made of bent wire. Johan Vaaler invented the paper clip.
The boggle dice on the plastic boat sunk the slowest. The bouncy balls on the Legos and the wood took the fastest to sink. The most that were in the boats were the quarters on the plastic. The fewest that were in the boats were the bouncy ball on the Legos and the wood.
Materials:
Plastic Cardboard
Lego’s Wood
5 gallon Bucket 4 gallons of water
Stopwatch Rocks
Quarters Boggle dice
Bouncy balls Computer
Camera Printer
Conclusion:
In my hypothesis, I thought the paper will sink the fastest because the paper will get wet and sink. As it turns out, I was wrong. The wood sank the fastest.
I think the wood sank the fastest because it was the thinest, flattest, and the lightest.
The following is what went wrong. At first we were going to use clay instead of plastic but when it touched the water it disintegrated. Plus we didn't use paper clips because I didn't have enough and because they were too light.
If I were to conduct this expriment again, I would probably place the weights evenly.
