The Rat Challenge
Evanston has a rat problem, and certain areas have high concentrations of rats. One Evanston park has been observed by Mr. Perrin to have rat nests right next to the playground equipment where children play. We plan to take students to this neighborhood park where they can observe the problem firsthand and get excited about problem-solving in our own community. Students will learn to use a science journal to keep notes, technical drawings, and observations. Through these summer activities students will learn about rats: their behaviors and how they have interacted with people throughout our history. We will research ways that people have tried to control rat populations and look at why no permanent solutions have ever been found. Students will be asked to brainstorm new solutions and ways to tweak old solutions. We will ask them to work in teams to design a humane “rat” trap, using classroom gerbils. Finally, teams will create a presentation, documenting their work, and making recommendations to the City of Evanston.
Engineering design challenge: A New Home for Rats
Design and build a device to channel the rats/ humane rat trap
Rats can get in but they can’t get out
- Device must collect at least 2 "rats"
- Rats must stay in their new home for at least 5 minutes
- Device must not harm the rats
