| Explore | We know that water tends to move from high concentration to low concentration. We also know that celery gets more flexibly when it absorbs water. |
|---|---|
| Research Question | How can we make the bendiest slice of celery. |
| Predictions | We think a thin slice of celery would become the most flexible. |
| Experimental Design | We will be using two cups of freshwater and one cup with saltwater. All the cups will have 1 cup of water. We will slice three pieces of celery that are the same length. One will be thick and it will go in freshwater. We will also have two thin slices. One of the thin slices will go in freshwater while the other will go in salt water. The control variable is the amount of water in all the cups which is 1 cup. The dependent variable will be how thick or thin we slice the celery. Finally the independent variable is how flexible the celery gets. |
| Conclusion | We decided to change all the cups to salt water because salt water seems to destroy the cells in the celery which should make the celery more flexible. We had three cups. Cup A had an uncut piece of celery, cup B had a celery which was a 1/2 inch thick and had the epidermis cut off, finally cup C had a 1/4 inch thick piece of celery with the epidermis cut off. We found that the thinner the celery was sliced the curlier it got. The curliest celery slice was in cup C where it was only 1/4 inches thick. I believe this happened because the thinner the celery was sliced the less support it had which also meant that it would be affected more by the water. |
