A mousetrap car is a small vehicle whose only source of motive power is a mousetrap. The mousetrap acts as a third-class lever, with the spring as the fulcrum and the hammer as the load. The vehicle works by winding the string around the axle the mouse trap's spring is stretched and now you have your stored energy, also known as Potential Energy which is the amount of energy an object has due to its position in space.
The goal of this lab was to build a mousetrap powered car. The mousetrap car needed to travel fifteen feet. The purpose of building these mousetrap cars was to demonstrate our knowledge of motion, friction, force, distance, and energy. We have studied these concepts, and each one is a factor in the success of a mousetrap car.
The purpose of the first investigation was to see if someone could survive a fall from an aircraft with a parachute or a raft. The MythBusters created "Buster," who was a fake body used to simulate a real person. For the first trial, Buster was attached to the middle of a raft. By the end, he wasn 't attached anymore and the raft flipped over like a coin in the air. However, the raft was like a parachute so for the second trial, the MythBusters hung Buster from the raft like a parachute. He ended up being all broken up, but he was still alive. During the third trial, an escape slide was used. It did not flip over, it gently floated to the ground. Buster was still intact and alive. However, this myth was busted because it is not realistic that anyone would be able to blow up a raft and have it fit through the plane door so that you
If one set’s out to build an empire, one will fail. All empires have humble beginnings. Just put one foot in front of the other, try not to stumble, and when one does, get up, and dust yourself off, and try again. How would the world go round without technicians? In fact, technicians fix all the problems normal people can’t fix.
Does the mass of a pinewood derby car affect the speed? If the mass of a pinewood derby car affects speed then the more mass the car has, the faster it will go. The procedures for the experiment were; Go get a pinewood derby track, car, scotch tape, quarters, and a timer. Set up the track. Make the derby car with the instructions included with the kit. Find the mass of the car with no weights added. Race the car 3 times down the track with no weight added. Record times. Add 6 quarters to the car, find the mass then race it 3 times. Record the results. Add 6 more quarters, find the mass then race the car 3 times, and record results. Find the mean for each weight division. Find out which one was the fastest. The control group is the car with no weights added. The experimental groups are the cars with weights added. An independent variable is the weight. The dependant variable is the speed. Some control variables are the track, wheels, and body style.
The scientific question answered was, “Does the length of a Pinewood Derby car’s body affect how fast the car will go?” The hypothesis was, “If the length of a Pinewood Derby car is shortened, then the speed will increase.” The independent variable was the length of the car, and the dependent variable was the time it took for the car to reach the bottom. There were many control variables, and some of them are the car used, the wheels used, the stopwatch used, and the ramp the cars were raced on. The control group was the Pinewood Derby car that had not been cut yet, and the experimental group was the two shorter car lengths. To perform the experiment, race the cars and record their times, then cut the car in half and make
Egg Drop Activity was one of my favorite experience that I was excited to explore in this class. while working on this activity, I had a fun time to cooperate with my classmate, Briana to try different ways to protect the egg. However, I was struggling to layering materials provided to protect the egg because I needed to hold the egg carefully. While exploring with this activity, I learned that from this experience that everybody had different techniques, and they also used diverse materials to protect the egg. Personally, I took a long time to think critically and creatively to make the protection for the egg. I also learned through play that I needed to add more bubble wraps and tissue papers probably to protect the egg. In addition, this activity also fostered my communication skills because I used languages to discuss and design the protection for the egg from breaking when it hit the ground. I learned from my peers that she was very patient to cover the egg by using the bubble wrap, tape, and tissue papers.
A Rube Goldberg project is a complicated way to do a simple task. In our project we decided to crack an egg. We designed a complex way in order to do this simple task. First of all, we decided to have a catapult fling a bouncy ball into to dominos which would set off a mousetrap. Then, the mousetrap would pull a string to releases a ball down a slide. The golf ball would fly down a race track and then set off another mousetrap. Next, the mousetrap would pull a string out of a book which would close the book on top of scissors. Finally, the scissors would cut a string which is holding up a dumbbell and the dumbbell would crack the egg which is sitting in a bowl. This is the project we decided to design in order to crack our egg.
Observing a group of three-year-olds can be entertaining since they tend to be energetic with their individual personalities starting to show. It was fascinating to see glimpses of their personalities, but what I really enjoyed was watching the pair of twin boys in the group interact with others. I observed a very small Sunday School class of three-year-olds at Conroe Bible Church. There were one girl and the twin boys along with their female teacher.
You could have designed a newton car a million ways but this is how I made mine. My design was different than a lot of the other cars maybe it wasn 't the best idea but i still rolled. So what I did to make my car is first I got a mini box and poked four holes on each of the bottom. Next I hollowed out pens to make axles and I suck them through the holes on the box. Also I suck wooden stakes through the pens to connect the my wheels. Then I super glued a balloon to a straw, then super glued the straw to my car. Then u blow up the balloon and then it will go.
In a Rube Goldberg experiment you can find many different physics concepts woven into its complicated transitions and exciting outcomes. During our experiment we used Gravitational potential energy, Kinetic energy, Momentum, mechanical energy, and elastic potential energy (among other things) to make this experiment happen. Our experiment started out with a type writer’s tab bar being pushed to push a car down a ramp, the typewriter has potential energy before the key is pushed as does the car. When the tab bar is pushed the typewriter, then has applied force which will change the energy from potential to kinetic energy. The transfer of energy from the typewriter to the car will change the car’s gravitational potential energy to kinetic energy and pushes the car down the ramp. Which send the car
My group members and I have been creating, the greatest, Rube Goldberg machine in our classroom! Our group and I have been researching about some possible ideas or objects we could use to build our Rube Goldberg machines. We figured out that we would use water bottles, dominoes, parts of a medium sized cardboard box, a marble moving set, marbles, confetti (to put inside the balloon to see when it pops), and tacks. We would put confetti inside the balloon for when the balloon pops, it will almost be like a big celebration! To pop the balloon we would use a few tacks and tape it onto the domino.
“Driving just fine? You’ve been swerving into the other lanes and hitting the rumble strips! You can’t even drive in a straight line. May I remind you that you almost hit an overpass?” My forehead was growing hot, and I could feel it spread to my cheeks. I leaned over the center console and turned the air-conditioning on full blast again.
