Hypothesis:
Top soil can reduce the most amount of water found beyond the soil bed compared to sand and clay.
Variable:
Independent variable - type of soil bed
Dependent variable - amount of water found beyond the sand bag
Constant variable -
duration of experiment for each set- up, size of bottle, volume of water, mass of soil

Procedure
1) Put 200g of sand in the soil testing device.
2) Pour 300ml of water into the 2L bottle containing the sand
3) Measure the amount of water left in the beaker
4) Record the reading into the table
5) Repeat the step 2 to 4 one more times
6) Find the average of the readings of the amount of water in the
beaker
7) Repeat steps 1 to 6 with top soil and clay soil
8) Compare the results of the three set-ups
Conclusion:
Clay soil is the best type of soil to be used in the sand bags to b
Areas for further studies
Conclusion
Clay soil is the best type of soil to be used in the sand bags to build the leeve.
