Simple machines is one of the science units explored in many grade 3-5 classrooms in the spring. A great culminating activity for this unit (that also ties into St. Patrick's Day) is to challenge your students to use what they have learned about simple machines to design and create their own leprechaun traps. Build background knowledge about leprechauns by sharing stories such as Jack and the Leprechaun, Leprechaun Tales or Gift of the Leprechaun. Students may also enjoy writing their own stories about how their leprechauns get caught . The next step is to use the Monster Physics app (lite version is free with ads at the bottom, upgraded version is $0.99 and ad free) to design a leprechaun trap. The design specifications for the trap are that it should be an original creation and it should include at least two different types of simple machines. By using the Build portion of the Monster Physics app, the students can create a trap and then actually test it to see if it works. To add some fun, students that create a working trap can collect a "pot of gold" reward from the teacher (foil wrapped chocolate coins).
Note: It is recommended that students work through the Missions (tutorials) portion of the app prior to using the Build section to create their projects. The app allows up to five different player profiles or avatars so it could be used successfully with student groups in a one iPad classroom.
