There are many exciting projects at Science Buddies for students. If you are interested in plants, farming, water recycling and food science, you may enjoy the hands-on projects below.
Project A: Sweet Potato Plants
Time required: Long (1+months) Cost: Low (under $20)
Do you enjoy eating sweet potatoes? They can be served as yummy snacks like mashed sweet potatoes with butter or golden-brown sweet potato fries. Do you want to grow your sweet potato plants and make tasty snacks at your will? In this science project, you will learn what part of the sweet potatoes is needed to grow the plants and how to make your own snacks.
Project B: Rooftop Gardens
Time required: Short (2—5 days) Cost: Medium ($20—$50)
Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being turned into beautiful green space which takes in CO2 while releasing fresh air. Besides, rooftop gardens also keep your house cooler and lower your energy bill. Try this science project to find out.
Project C: Recycling Greywater
Cost: Medium ($20—$50)
Time required: Long (1+months)
One way to conserve water is to find safe ways to use it more than once. Here is a project to test whether greywater (water that has been used for washing or bathing) can be used for watering plants. The goal of this project is to find out the effects of greywater on plant growth and health.
It is important to note that used toilet water (blackwater) is absolutely not suitable for re-use. It must pass through a water treatment system before being released back into the environment.
