| Explore | We know that plants can produce oxygen. We know how plants grow from water, sunlight, and carbon dioxide; and how they produce oxygen. What question interests us is what liquids allow them to germinate. |
|---|---|
| Research Question | Does the type of water affect the germination of a seed? We came up with this question by looking at a list of questions. Our question fits the topic because we already know about the different types of water and how the germination process works. |
| Predictions | We predict that the regular water and the mix of 0.1 g of baking soda and 0.5 ml of water will make the plants germinate and the rest won't make it germinate. |
| Experimental Design | 1. Get 5 pieces of paper towel. 2. Get 5 ml of tap water, 5 ml of water and 0.5 g of citric acid, 5 ml of water and 0.1 g of citric acid, 5 ml of water and 5 g of baking soda, 5 ml of water, and 1.25 g of baking soda. 3. Measure the PH of each liquid. 4. Wet the pieces of paper towel and set them in plastic bags. 5. Put 8 tomato seeds on the paper towels 6. Give the seeds 5 ml of their liquid each day. 7. Check and see how many seeds have germinated each day. |
