The objectives for the challenges in Activity 10 through Activity 15 of this PAC include: Challenge 1 You will conduct research on a career of your choice in the hydroponics field. Share your findings in a presentation. Challenge 2 You will select a type of hydroponic culture and prepare information about that culture. Challenge 3 You will conduct an experiment to determine if light color affects plant growth and development. Challenge 4 You will design and/or construct a hydroponic growth system. Challenge 5 You will transplant your lettuce plants into your own hydroponic growth system or traditional soil culture. Challenge 6 You will research and write a paper about a specific hydroponic crop. |
