If you have not already, you or someone you know will try to grow a variety of plants either inside your house or outside in a garden. What type of soil do you need? How often should you water the plants? Should you plant them in full sun? Why do some plants need less water and some more? These are questions that many people have about plants. In this activity, you will have a chance to manipulate different variables to see how much water some plants use and how much some lose through transpiration.

Objectives

1.Conduct virtual experiments to determine factors that affect transpiration.

2.Compare and contrast sustainable and unsustainable farming practices.
