This section provides a practice opportunity using two virtual labs. Virtual labs are relatively efficient, contained environments. They are designed to give students practice with designing and conducting virtual investigations in preparation for designing and conducting their own hands-on investigations. If you are using these in a classroom, virtual labs take between 2 and 4 class sessions to complete. The lab, How Does Your Garden Grow?
