What was done? 20 pre-trials were completed with 10 commercial apple and 10 non comercial trials.

I'm Nick Pierce from 9A, your grammar and wording in the Pre-Trials blog was off. "We decided to use a beaker to wash the apple instead of using the tong to wash the apple." What do u mean use the tong to use the apple you can't wash an apple with tongs. Other than your grammar your blog was really good.

Thank you for pointing this out. We had meant that we were gong to wash the apples by swishing it in the beaker rather than using tongs to dunk the apples in a bucket.

I am from 9A, I would like to know what type of apples you used, because the type of apple may effect the test results?

Thus far we have tested on Fuji, Macintosh and Gala apples. The type of apple being tested does not affect the TDS reading since it only records what was washed off of the peel.

My name is Luke Sanders from Fitzgerald (Class 9A). I think the experiment is very interesting. There's all these warnings and people saying "Don't eat store sold apples, they're covered in pesticides." But there's not a lot of people comparing both store bought and roadside. One thing that was an issue, under the section "What was found and changes?" in both the second and third bullet point have the misspelling of "change" instead of "changed"

Thus far commercial apples tend to be more contaminated than non commercial apples. So we recommend buying local. Hope this helps!

Why did you have to use distilled water?
Reply
Danielle Didia
11/5/2017 05:05:30 pm
We used distilled water because normal tap water has a TDS rating above zero. Theoretically we could have recorded the difference in the readings before and after washing the apple, but we noticed a greater difference in the reading with distilled water. We accredited this to the fact that distilled water has a reading of zero, so it was easier to discern the difference.

We did this by having an average of at least 75 apples for each population. The central limit theorem then says that that population would be closer to normal than an individual trial.

No, as long as we ensure that the TDS reading of the water before washing the apple is zero the trial is okay.

Apples are actually among the most pesticide laden fruit. So we thought they would be perfect to test commercial versus non commercially grown sources. They were definitely not the cheapest option, but they were the best fit for what we were testing.

Why did you decide to have 20 pre-trials? For example, why not use 10, 30, or 40?

We had 20 because its what our resources allowed, and we had already finalized our design and methods for the actual trials.

This was tested in pretrials, and the difference in times had negligible results.

The non commercial apples are homegrown. They are coming from either my backyard, a farmers markets, or friends and neighbors that have apple trees.

Your proposition was tested in our pretrials. We found that although the results vary slightly, the overall effect in a longer time is negligible.

Apples are known for having a high pesticide contamination. We essentially wanted to see how different commercial apples were compared to homegrown.
