My Science Project

• Bananas
• A Clock
• A Towel
• A freezer
• A refrigerator
• A deep kitchen drawer
• Notebook for the Data

Conclusion

I like bananas. But I hate when they have brown spots all over them.

So my science experiment answers the question:

In the end, I found out that the banana in the drawer, wrapped in a towel, actually had the fewest brown spots. I believe this happened because it was actually kept from air exposure and air stimulates the ripening process, making bananas turn brown faster. (By the way, the ripening process is actually when it starts to turn brown). The banana that was in the fridge actually had the most brown spots but had a firmer texture. The one in the open had a few brown spots and was soft in texture. The freezer banana turned as hard as a hammer, was frozen solid and completely brownish-orange. I took a picture of an extra bundle and all of the bananas were more brown than any one of the bananas I experimented on. This is because if you separate them then it will slow the ripening process down. I learned in my research that bananas release an ethylene gas and being separated slows that down. I hope you enjoyed this and thanks for listening.

Maybe you can apply this to home too.

My Hypothesis

Independent Variable

Does the temperature of

where a banana is stored

affect how quickly it browns?

I believe that the banana in the fridge will not brown as fast because I have heard that, but, who knows? Also, it seems like the warm blanket just makes it heated and mushy like fried bananas. The room temperature is just normal and the ripening process is faster. And the freezer sounds like it would freeze the banana!

What I changed:

I changed the places of where the bananas were being stored so that they would each be in different temperatures

The banana in the freezer:

The banana in the refrigerator:

Dependent Variable

Procedure

What I measured:

I measured the amount of time in between each observation and I observed the differences in each banana

1. I bought one bundle of bananas

2. I took them home and separated four of the bananas from the bundle. I put each one in four different types of storage: the freezer (very cold), the refrigerator (cold), on the kitchen counter (room temperature), and in a drawer, wrapped in a towel (warm).

3. Over the next four days, I carefully observed each of the four bananas by checking on them everyday. I took pictures and wrote down my observations.

4. I used the information I collected to complete my research and conclusion.
