Project Learning Tree (PLT)
PLT's Secondary Modules
The secondary modules give middle and high school students opportunities to apply scientific processes, higher order thinking skills, investigate topics in-depth, and conduct service learning action projects.
PLT's secondary modules are designed for middle and high school educators. Each module offers eight in-depth activities, focused on specific topics. (Biodiversity has three in-depth activites.)
The only way to get any of the Secondary modules is to attend a PLT workshop.
