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! Read more

A hydroponics experiment gave this student more than just the chance to learn more about growing plants. She also cultivated strong problem-solving skills as she moved her experiment to the garage. Above: Madeline at the science fair with her hydroponics project. No matter where you live, fall and winter months are not necessarily the best months for doing plant biology projects, but at Science Buddies, we know that picking a project of interest can make a… Read more
