| Explore | We know that plants need water, nutrients, sunlight, the correct temperature, and oxygen to grow. We have learned in class what photosynthesis is and why plants do it. Water is necessary for photosynthesis, which is how plants use energy from the sun to create their own food. During photosynthesis, plants use carbon dioxide from the air and hydrogen from the water absorbed through the roots and release oxygen as a result. We know that glucose acts as food for the plant. We are interested in knowing why plants need water and what percentage of water is actually in the plants. |

| Research Question | How does the type of liquid affect the plant's growth? |
| Predictions | We predict that water will work the best, and it will make the plant the healthiest and largest because plants tend to grow better with water. |
| Experimental Design | We will have 6 Petri dishes, 2 of each liquid with 6 seeds per dish. The liquids will be water, apple juice, and sprite. We will put one paper towel per Petri dish and place 6 seeds in each dish. Then, we will wet the paper towel with 5 drops of each liquid ( per dish) from a pipet. We will wait for the seeds to germinate and then measure how big each plant grew. |
