produce science and the fence

Well, is has been awhile....but I have an excuse. Not a good one, but it IS an excuse. "I couldn't log in." I couldn't figure out why, then I remembered, I changed my Google password when I got in to eCrater. So I figured it out, finally!

This is what was happening while I was trying to log on. Dave and our neighbor decided to replace an aging fence, so they bought the wood and geared up. Then it rained. A lot. Well, they finally got clear skies on a weekend they could both work on it.

Here are the pictures Joseph and I took of the science experiment he did for the upcoming science fair. We actually took about 50 pictures, but we didn't print them all and only used 10 of the ones we printed. He was supposed to inhibit the enzyme that makes apples and potatoes discolor be using lemon juice and record the time it took for each to turn brown. It took a long time. We watched them for 5 hours!

It was very boring.
The experiment that he received called for each apple and each potato to be done individually, but I decided it would be easier if we ran them all together at the same time and simply took photos to record the data.
I helped him make a very simple poster about the experiment. Simplicity won out, he was in the roughly 1/2 of students who didn't have to bring theirs home to fix up.

I will take pictures at the science fair when we go.

And finally, don't click on links in comments unless the comments are signed. There are spam and phish comments that I can't delete. I can prevent them by making you type some stupid distorted letters before you comment, but do you want to do that?
