POSTPONED - 2021 4-H Mousetrap Car SPEED Challenge

Due to the ongoing pandemic, the MMousetrap Car SPEED Challenge  will not be held at a large public gathering this summer.  We are planning for a smaller outdoor event this fall.

The 4-H Mousetrap Car Challenge is a contest for youth eight and older to design and build a vehicle to travel as fast as possible, powered solely by one standard-sized mousetrap.  Anyone can build a mousetrap car.  You will need some cardboard or other material for a car body, DVDs or other round objects for wheels, some string, a few other things, and, of course, a mousetrap.  Once you build a car and make it work, take time to tinker with it to see if you can make it go faster.  Then come race your car this summer at the 4-H Makers Expo in North Haverhill NH.  Cars will be electroni cally timed of a 15 foot distance.  The car that travels the fastest will be declared the winner.  Awards will be given to the top three cars.

Registration for the 4-H Mousetrap Car Challenge and other Maker Expo events opens June 1st through 4-H Online.

Parents, please note The Mousetrap Car Challenge is a youth contest and mousetrap cars must be built by youth.  While it is tempting to step in and build or fix your childs car, they need to do this on their own.  Although it can be hard to watch them struggle, their struggles and mistakes will help them build patience and skills.  Ways you can help and support your youth include:

  1. Let them struggle a little, then ask supporting questions like, "What do you think is making it run crooked?"
  2. Sometimes you can add your observations like, "I noticed the wheel rubbing against the body, how do you think that affects the car?"
  3. Build your own car along side them and show them each step as you each build a car together.
  4. Avoid negative comments and pointing out mistakes.  Instead help them see what went wrong and encourage them to make changes.  "I noticed that the wheel is really wobbly, what do you think would happen if you straightened it out?"
