Any science fair project connected with agriculture might easily incorporate ideas and methods from biology to engineering and ecology to computing. Food production is essential to our very survival but is a subject often overlooked when choosing a science fair project.

• Can food plants be grown in a hydroponic system?
• Will plants grow better in soil, artificial substrate or water (hydroponic systems)?
• Does the growing media alter food taste?
• How does acid (polluted) rain influence crop yields?
