Why Lesson Planet?
Learners read the story, Dear Mr. Henshaw. They build an alarm system for something in the classroom, as the main character Leigh does to protect his lunchbox from thieves. Students explore alarms and use their creativity to create an alarm system to protect their lockers, desk, or classroom door. They draw the design of their alarm system on paper, including an explanation describing what their alarm does, how it works, and what materials were used.
