1. How much water, how much sunlight, the container shape, and how much soil.
2. The type of soil
3.Which kind of soil grows the plant the best and what plant grew the most.
4. We are measuring the length of plants that grow in organic material and inorganic material and see which one grows more.
5. We need to test so many plants because there could be flooks like I me Gavin and Ian were in the same group Gavin got 16 I got 24 and Ian got 0 if we only did one Ian's might have thrown off the whole project.
7.These pictures show that the root grows first because the part that is growing is growing down and it looks like a root.
8.I think it goes in that order because the plant probably needs water before it needs sunlight so the roots go down so it can find water then uses the water to get energy and matter then grow up and get sunlight.
