About This Chapter
Engineering Projects - Chapter Summary and Learning Objectives
By implementing the projects that are found in this chapter, it will not only help increase the knowledge of engineering concepts, it will also help students visualize these concepts. Experiments that will be addressed in this chapter include those regarding electric generators, homopolar motors, electromagnetic induction and soda can crushers. Other projects in the lessons include:
- Bridge building
- Paper roller coaster
- Making tissue paper hot air balloons
- Building mousetrap cars and paper bridges
- Constructing paper rocket launchers
- Paper rocket ships
- Balloon powered cars
- Windmill generators
1. Soda Can Crusher Lab
In this experiment, we'll be learning about how pressure changes during phase changes. By the time you're done, you'll be able to describe how a phase change from gas to liquid can generate a force great enough to crush a can.
2. How to Make a Balloon-Powered Car Project
In this engineering project, you will be making a car that is powered by air from a balloon. Vary the sizes of the balloon to see how it affects the distance your car travels.
3. Bridge Building Project
The goal of this project is to apply concepts in physics to build a bridge that holds the most weight. At the end of this project, you will understand basics in engineering bridges and create your own bridge.
4. Electric Generator Science Project
In this science project, you will be creating your own electric generator. Using cardboard, a nail, wire and magnets you'll be able to recreate the process of generating electricity for your home and light a small light bulb.
5. Electromagnetic Induction Experiment
In this lab, we're going to use the principle of electromagnetic induction to generate electricity. We'll be studying how the number of coils of wire and movement of the magnet can affect the current generated during electromagnetic induction.
6. Electromagnet Science Fair Project
In this project, you'll be learning about electromagnetic induction. Here, we'll use the current supplied in a circuit to turn a regular nail into an electromagnet. By the end, you'll be able to demonstrate the relationship between current and an induced magnetic field.
7. How to Make Ferrofluid Science Project
In this engineering project, we'll be making our own ferrofluid. By the end of the project you'll understand what ferrofluids are and why they are important.
8. How to Build a Suspension Bridge Model
In this project, you'll be creating a suspension bridge. Through building this model, you'll understand the principles of force distribution and how engineers use cables to accomplish this in suspension bridges.
9. Maglev Train Science Project
In this project we're going to be building a model train that floats instead of rests on tracks, called a maglev train. By the end of the project you'll understand how forces interact to change the motion of an object.
10. How to Build a Mousetrap Car
In this engineering project, you'll be learning how to harness the potential energy in a mousetrap to power a model car. By the end of the lesson, you'll understand more about energy conversions and the law of conservation of energy.
11. How to Make a Paper Bridge
In this project, you'll be designing a paper bridge. Here, you'll learn how different structures distribute forces that could cause a bridge to collapse and gain a better understanding of how real bridges are constructed.
12. How to Make a Paper Rocket Ship
In this engineering project, we will be looking at some important structural features in a rocket ship. The purpose of this project is to build a rocket ship out of paper that travels as far as possible.
13. How to Make a Paper Rocket Launcher
Do you enjoy watching rockets being launched high into outer space? If so, this is the project for you. In this engineering task, build your own rocket launcher and paper rocket. Use your launcher to see how far your rocket will travel!
14. How to Make a Paper Parachute Experiment
In this project, you'll be designing a paper parachute to maximize the time it takes for an object to fall to the ground. In doing this, you'll understand how different modifications to the parachute can influence the forces acting on it and thus influence the impact of the object on the ground.
15. How to Make a Balloon Powered Car
In this engineering project, you'll be designing a balloon powered car. Here, you'll learn about how Newton's third law can be applied to design propulsion vehicles like our car or a rocket.
16. How to Make a Rubber Band Car
In this engineering project we'll be learning how to make a rubber band car. By the end of the lesson you'll understand how the law of conservation of energy allows a car like ours, without an engine, to soar across the room.
17. How to Build a Trebuchet
In this project, you're going to be building a model trebuchet. Although you won't be able to storm cities, this project will teach you about kinetic and potential energy as well as the law of conservation of energy.
18. Water Filtration Science Project
In this engineering project, you'll be designing a water filtration system. By combining different materials to create a filter, you'll be able to clean dirty water. By the end of this project you'll understand the importance of water filtration and how to filter dirty water.
19. How to Build a Windmill Generator Science Project
In this project, you'll be making your own wind generator at home. It won't be big enough to power your entire house, but you will be able to light a light bulb using a simple turbine.
