Science Fair Topic Ideas in Engineering

Engineering, of the seven categories of science fair project most commonly used by elementary school students, usually conjures up images of building things. But engineering encompasses everything from design to building to computer and social engineering. Here are some science fair topic ideas in engineering. 

Bridge Science Fair Projects- Build and Design

Seeing how much weight your bridge can bear, exploring the different types of bridges to build and design, making bridges out of paper or exploring why some bridges hold up during natural disasters and some do not are just a few of the bridge science fair projects for your kids to try.

Simple Machines Science Fair Projects

Predicting how many simple machines can be found in one room, learning about and explaining what a simple machine is are two simple machines science projects. Your child might also like examining which simple machines are used most and why that’s the case can be a really interesting way to learn about the wedge, lever, pulley, wheel & axle, inclined plane, and screw.

Rube Goldberg Machine Ideas

Most people have seen Rube Goldberg machines in action, those machines in which one action cause a reaction which in turn causes another action until at the end something interesting occurs. It would be a great science fair challenge for your child to come up with his own Rube Goldberg Machine ideas. Although the concept of action and reaction is physics concept, building a Rube Goldberg machine is a feat of engineering that uses simple machines.

Computer Engineering Science Experiments

What makes some computers run faster than others, discovering how fast your computer is, an explanation of how Google gives you results, a comparison of basic computer programming languages your child learns are few of the exciting computer engineering science experiments your child can try out.
