Examples of mechanical projects for students include building simple machines such as water clocks and catapults. More complex projects involve building water pumps and anti-gravity lifters as well as testing the laws of physics.
Building a water clock is a relatively easy mechanical project for students. The objective of the project is for students to design and build an effective water clock that actually tracks time.
Building a catapult also involves designing the machine first. After building a rubber band catapult, students test different settings to see which launches a ping pong ball the farthest and at what angle. Students can also build an Archimedes screw pump. Such a pump is relatively simple yet transfers water from a low-location to higher elevation.
A more detailed mechanical project for students is building an anti-gravity lifter. The specifications of the lifter are based on the Biefeld-Brown effect. For this project, students utilize high voltage batteries to create a situation in which the natural tendency of positive and negative poles causes a lifter to float over the ground.
Another mechanical project for students tests Hooke's Law, which states that a spring extends in direct proportion to the amount of force applied to it. Students create a system of hooks and springs on a three-dimensional board to test this law.
