Problem/Question: How much water can be drained through any sediment size and kind?
How do(es): sediment size (independent variable)
affect: drainage (dependent variable)?
Hypothesis:
If the sediment size is larger (planned change in independent variable),
then it will go and drain faster (predicted change in dependent variable).
I think bigger sediments drain faster (restate relationship above),
because it’s bigger and the sediments won’t cover every hole that water will drop down in. (include background knowledge AND provide references to support your prediction).

Procedure:
Include an easy-to-follow, step-by-step, set of instructions repeating the experiment.
- Get paper and make a cone-shaped filter, then put it on top of the graduated cylinder.
- Get 3 types of sediments, sand, humus, and gravel that measures about 20 ml using a beaker, then pour it in the filter.
- Get a 3 timers.
- Get 3 beakers and get water that contains 16.7 ml for each beaker, then pour it in the filter, then use the timer to time each sediments that are in the graduated cylinder fro 3 mins, then stop the timer.
- Watch and see how much water drained from each sediments.

Conclusion:
The conclusion of this experiment was that my hypothesis was supported because in the experiment, bigger sediments make water drain more faster because when the sediments have bigger shapes, it’s all together, so they have bigger holes left for the water to drain, but if the sediments are small and more, it will cover almost all the holes, so it would drain little water, and it will be saturated later on.
Connect to the Hypothesis – Was it supported or rejected? My hypothesis was supported because bigger sediments make it not crammed up, so there are bigger holes when the water could drain faster too.
Make a concluding statement related to the Problem – Use data to support the statement.
Explain the Data – Provide reasons why the data is what it is and how it connects.
Gravel has the biggest sediments so it wouldn’t be crammed up when we pour the water in the filter, so the water came down more that others because it didn’t have to wait for a long time until it saturates.
Evaluation:
What I did well was knowing what the process of the experiment and the part that I need to improve on was collecting more data, when we were doing the experiment.
