Key Concepts
Hydroponics, plant biology
IntroductionDo you think plants can grow without soil? If you've tried growing veggies, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil too, using a process called hydroponics. In this activity you will transform a two-liter water bottle into a mini-garden that needs only light, air and nutrient rich water to grow!CreditsSabine De Brabandere, PhD, Science Buddies
Hydroponics growing system adapted from "Build a 2 Liter Bottle Hydroponics Garden" by Epic Gardening.
This activity is not appropriate for use as a science fair project. Good science fair projects have a stronger focus on controlling variables, taking accurate measurements, and analyzing data.
