Nathan's 2nd Grade Science Fair Project

Since Nathan attends a Math, Science, Technology school, he is required to participate in Science Fairs. This year is our first. Personally, I never had to do one of these in school, so it's a new experience. Our project was entitled, "Green Saves the Green." You've seen those green bags on TV.... the ones where the food stays fresh longer. We decided to put this product to the test.

We had 12 bananas that we had paired off and put in: a green bag, a brown bag, a Ziploc bag, on a plate, on a banana holder, and in the refrigerator. We then took pictures daily and after 8 days, we did a blind taste test. The results were that the green bag did actually keep the bananas fresher longer. At the taste test, they tasted better than the rest.

Bad news for the banana holder though, the bananas on a plate lasted longer than being hung on the holder. One definite piece of advice, never put bananas in the refrigerator. They discolored quickly and lost their flavor.

Nathan's project is due this coming Tuesday, so we spent several hours this weekend completing the display board, pictured above.

The project looks great, Nathan! Very useful information for us since we are a banana eating family.
