Mariam wants to know which minerals are important for plant growth.

She takes four samples of pure water and adds different minerals to each of them.

Then she puts a seedling in each sample of water.

After 2 weeks she compares the masses of the seedlings.

Suggest things Mariam kept the same for every mineral solution she tested.

• volume

• Temperature

• number of leaves

• size of leaves

• length of seedling
