Say you are going on a picnic and you want to bring bananas. Well, the bananas are on sale, you go ahead and get them. The picnic isn’t until October 28, you doubt they’ll last that long. You go home and put two in the refrigerator, two in a bag on the counter, and two on the counter in a fruit basket. Your problem is "Will the green bananas last longest in the bag on the counter, in the refrigerator, or in the fruit basket???“You are trying to see if the green bananas will stay green until then.
Hypothesis- a statement or prediction that can be tested. My Hypothesis: “If I put two bananas in a bag on the counter, two in the refrigerator, and two on the counter, then the ones in the refrigerator will last the longest.”
Materials: Big paper bag 6 green bananas Marker Refrigerator Paper Pencil
Steps: 1. Gather materials 2. Open paper bag 3. Put two bananas in the paper bag and place on the counter 4. Place two bananas on the counter 5. Put two bananas in the refrigerator 6. Label each group; write “Abby’s Experiment” 7. Collect and record data that shows how yellow the bananas are over a period of 1- 7 days 8. Draw a conclusion 9. Communicate your results 10. Have your picnic!
Day 1Day 2Day 3Day 4Day 5Day 6 Group 1 Bananas are green Bananas are turning slightly yellow Bananas are yellow Bananas are yellow with brown spots Bananas have lots of yellow spots and are yellow Bananas have very many brown spots Group 2 Bananas are green Bananas are turning yellow Bananas are yellow Bananas are yellow with a few brown spots Bananas are yellow with more yellow spots then Day 4 Bananas are almost completely brown Group 3 Bananas are green Bananas are still green Bananas are in between green and yellow Bananas are yellow and green in places Bananas are yellow and green Bananas are yellow and green just as Day 5
My question that I stated is "Will the green bananas last longest in the bag on the counter, in the refrigerator, or in the fruit basket?“My hypothesis is “If I put two bananas in the refrigerator, two on the counter in a paper bag, and two in a fruit basket then the ones in the refrigerator will last longest.”The materials I used were a big paper bag, 6 green bananas, a marker, refrigerator, paper, and a pencil. My procedure is first you gather materials, second you open the paper bag, third you place two bananas in a paper bag. Fourth, you place two on a counter. Fifth, you place two in a refrigerator. Sixth, label each group “NAME’S EXPIREMENT” with the marker. Seventh, you record and collect data that shows how yellow the bananas are over a period of 1-7 days. Step eight is draw a conclusion. Step nine, communicate your results to your class mates. Last but not least, go somewhere nice and have a picnic! My methodology was observing with my eye sight and recording how yellow the bananas got. My bananas were all green on Day 1. They got either yellow or stayed green on Day 2. The bananas just got more yellow on Days 3-6. I used the scientific method by using all the steps of the scientific method. I stated my problem, formed a hypothesis, I tested my hypothesis, recorded data, analyzed my results and drew conclusions, and communicated my results.
I concluded that the bananas in the refrigerator lasted the longest. My hypothesis did hold because they only got 21% yellow and the rest were more yellow. They also didn’t look like the kind I would want to eat, but that’s my opinion.
My form of communication is a PowerPoint Presentation. Some people do a poster, some create websites or blogs, or some just do a paper and present it in front of a class or students.
I learned how to use the scientific method properly when doing an experiment and how scientists use it.
