Transcript of Katelyn Flannery 2012/13 Science Fair Project Mrs. Stambaugh
2. Cut 1 apple into wedges and remove the seeds.
3. Count the seeds.
4. Mark the number of seeds on the log sheet.
5. Repeat the procedure with 3 apples from each type.
6. Finally, calculate the average number of seeds for each variety. Seeds play a critical role in the growth of an apple. After bees pollinate the apple tree blossom, fruit begins to grow. Seed chambers called carpels form and can contain from 5 to 12 seeds. Even though there are close to 100 varieties of apples, only 15 types make up 90% of production in America. In 2007, the U.S. Apple Census reported that there were 25,591 farms growing apples. This means that picking the right apple could make farming a lot easier.
If I collect and count the seeds from Red Delicious, Gala, and Granny Smith apples, then the Red Delicious apples will produce the most seeds. Katelyn Flannery
Science Fair Project
Mrs. Stambaugh Johnny Approved Apple Seed Project The purpose of this experiment is to see if the color of the apple determines the number of seeds it will produce. I became interested in this experiment when I saw it on a website. I thought the results might help farmers know which apple tree has the best chance of reproducing more apple trees from the seeds of fallen apples. 1 cutting board
1 apple wedger cutting tool
3 Red Delicious apples
3 Gala apples
3 Granny Smith apples
1 log sheet
1 pencil Purpose The results of the experiment were that the Red Delicious and Gala apples actually contained the same number of seeds with a maximum of 6, while the Granny Smith green apples made up to 9 seeds in the first trial. Overall, the Granny Smith green apple averaged more seeds over the 3 trials. The data would suggest that there isn't enough consistency linking the apple color and number of seeds produced to make it useful for farmers. The results indicate that my original hypothesis should be rejected since the Red Delicious apples actually made less seeds than the Granny Smith green
apples. Because of the results of this experiment, I wonder if other varieties of apples would have the same results. If I were to conduct this project again, I would try to see if the number of seeds are dependent on the region they are farmed. Hypothesis Sources Source 1:

This source was used to find information about how many pounds of apples are consumed in a year. Also, I learned that apple formation is dependent on the seeds..

This source was used to learn about the number of farms that grow apples. It also told me about how many acres of apples there are in America. Bibliography Experimental Design The Manipulated variable for this experiment is the type and color of apples used.
The Dependent variable for this experiment is the number of seeds counted.
The Constants for this experiment is the procedure and materials used.
