| Explore | I know about perennials and annuals. I have learned that perennials are plants that do not grow back every year and annuals do grow back every year without having to replant them. I wonder how trees stand up and what plants mate. |

| Research Question | How does the amount of salt in water correlate to the bendiness of celery? |
| Predictions | If you add more salt to the water then the celery will be bendier. |
| Experimental Design | Step 1: Get celery sticks & cut them with a scalpel. Cut into 3 thin pieces (Less than 1.5 cm will be considered a thin piece of celery) & 3 thick pieces (More than 1.5 cm is a thick piece.) Have 3 cups filled to the top, with Tap water, 30% salt and 50% salt. Step 2: Measure the length and width of the celery sticks & make a data table. Step 3: Put one thin & one thick piece into each cups of water (same cup). Step 4: Leave the celery in for 2-3 days and after the days are finished take the celery out & measure the length and width of the celery that has been soaking. Step 5: Measure the celery for each of the days 1-3 to see how they increasingly bend. Independent Variable: Amount of salt in the water Dependent Variable: The bendiness of the celery |
