The mousetrap car project is a classic physics challenge: Build a vehicle that can travel as far or as fast as possible by using only the energy that can be stored in a single mousetrap. Seems simple enough, but the reason it's so popular is because it's rich in science concepts, applied math, and design possibilities. For example, you can calculate the mechanical advantage to determine how efficiently the car is utilizing the energy from the mousetrap, or calculate the minimum distance the car will travel! This Instructable will focus on how to build a mousetrap car that travels as far as possible using only the materials that are shared with all of my other STEM Projects for Kids plus mousetraps of course. Read on to the end of the Instructable for a detailed explanation about the science and math concepts that are being applied, how to optimize the mousetrap car to go as far as possible, and downloadable classroom resources including a lesson outline and project sheet.
Add Teacher Note. Other ideas for improving the car: make it more durable by using lightweight wood such as balsa or basswood instead of cardboard. Note: if your wheels are smooth, you might need more traction for the car to operate properly. Energy can be classified in a xource of ways but most commonly energy is classified as potential and kinetic. Let the mousetrap arm close it points past the front wheels.
Energy source rubber band mouse trap. Mousetrap Vehicles: Energy
With kinetic energy, an objects speed is much more important that it's mass, doubling an objects speed and it has four times Bedwetting teenage energy. Trim away the center of the rear piece where it stretches across the rubebr in the chassis. Friction The biggest enemy of a high performing mousetrap car is friction. Last thought. Great design!
After checking their cars one last time, racers gather at the starting line.
- Energy is what does work.
- What's new.
After checking their cars one last time, racers gather at the starting line. Spectators and a television news crew line the course. Students prepare for a heat in the trapster races. Media credit: Douglas Manelski. The Indy ? Not quite. Each Energy source rubber band mouse trap, Feil tweaks the rules.
This year the distance was just ten yards, with awards for speed and aesthetic appeal. Designing a Faster Mousetrap. Media credit: Doug Manelski. For others, it was more of a stretch. The students also had to make their trapsters aesthetically appealing.
Others emulated traditional racecars. Although everyone was nervous and sleep deprived, there was also a sense of relief, says Tung.
Two cars raced in each Teen father photos, with results displayed on a large screen.
And that camera positioned for photofinishes? It helped build skills in many different areas. Story by Nancy Joseph. April Perspectives Newsletter. Undergraduate Education.
Energy of Springs and Rubber Bands. A stretched and/or compress spring/rubber band has potential energy because of the it's position. When you stretch a spring or rubber band you can feel the energy being stored as the force of the spring or rubber band pulled back; it is easy to see that the stretched spring or rubber band has energy in waiting. May 25, · Hello, I'm trying to find the amount of stored energy in a mouse trap when it is set. I've read up on Potential energy.. but all i've found is gravitational, electrical, or elastic potential energy.. and that E = MGH.. but i don't have any height.. but if anyone can point me in the right direction. Jan 11, · Your model car will use a rubber band as the source of energy. It will take a little engineering to get your vehicle working—challenge yourself to see how far your car can go!Author: Ben Finio.
Energy source rubber band mouse trap. Step 2: Make the Drive Wheels
Now that you've seen how the car is built, here's an overview of the science and math that's behind the car: The basics The mousetrap stores potential energy in the form of the spring. The secret behind Doc Fizzix's top secret propulsion system is the advanced pulley system that allows a rubber band to be stretched to it's maximum capacity for maximum potential energy. The best mousetrap car is one that starts by slowly crawling forward, using the smallest amount of energy possible to get moving. Spectators and a television news crew line the course. This sandwiching technique ensures that the mousetrap car arm has a solid foundation and won't bend or break during use. Circuit Science Projects. The potential energy in the stretched band was converted into kinetic energy propelling the car forward the same energy transfer occurs in a mousetrap car. A handful of rubber bands Two small cup hooks What You Do: Cut a six-inch length of balsa wood to be the car body, or chassis. Share it with us! Bulk pack of this kit available see below. Your car is ready to roll! This isn't totally necessary, but it will make the next steps a little easier and may add a small amount of efficiency to the car's performance. Cut off any excess dowel picture 1. Energy is what does work. Your rear axle will be accessible through this notch.
A stretched rubber band is a great source of elastic potential energy.
With just a few parts a wooden base, a spring, a metal bar, and a trigger mechanism it can do its job quickly and efficiently. There are already 4, mousetrap patents issued by the Patent Office, and people apply for new patents every year! But only a couple dozen of those thousands of mousetrap designs have ever made money, and the simple snap-back is still selling strong more than one hundred years after it was patented in When a mousetrap is set , the spring in the center is compressed, becoming a source full of potential energy. This energy is being stored, not used, but as soon as the trap is released, it is converted to kinetic energy the energy of motion that propels the snapper arm forward. A mousetrap makes use of a simple machine called a lever. There are three different classes of levers.
