This simple, yet helpful, graphic organizer helps students understand the process of exploring their thinking and different concepts as they construct projects, etc. Consider having this tool be a part of your APK, EPK, application, and reflection. Combine it with a project listed above (and a clear learning target) and you have a lesson plan!
This would be fun for a history, ELA or science classroom. This activity has students "digging" through trash to detail, trace, and infer things about people from what they discover. It could help students understand how historians learn about the past, how scientists use data to make inferences, or ELA students learn how they can draw certain conclusions without information being in the "trash" or in the "text"; rather, we can infer from the data that we do have!
Best for science or physics class, this lesson is a great way for students to study motion and the transfer of energy. They can also compete, which they always love. Lesson materials can be found here:
Change the search scope to Classroom Resources and then search "Catapult."
I love engaging tasks that are easy to plan. Check out this link for a fun activity for kids of all ages. As kids eat, touch, smell, and feel different foods they observe characteristics of them. They then switch their descriptions with other kids in a creative game format.
I love quick tips to sprinkle something into an existing lesson plan. This is a quick list of things that a teacher can do to embed project based learning to "STEM-Up" a lesson. It would be a great quick-read for a PD as well.
