Science Fair Project Idea
In our , you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is similar to the concept of… Read more

Virtual reality (VR) headsets are becoming increasingly popular with consumers for things like viewing 3D pictures and videos, or for playing video games. However, dedicated gaming headsets like the Oculus Rift® and PlayStation® VR can cost hundreds of dollars. Some headsets, like Google Cardboard™, which is literally made out of folded corrugated cardboard (Figure 1), are much cheaper because they can use any smartphone as the screen. Figure 1. A Google Cardboard headset… Read more

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Read more

In our , we provided a template with four materials: two active materials that expand and contract in the physics sandbox mode, and two passive materials — one hard and one soft. The project mentioned material properties, but it did not go into much detail — you just used the default settings from the template. Changing the material properties can drastically change how your robots behave. Engineers must take material properties into account when designing robots and other machines.… Read more

Science Fair Project Idea
How easy is it for you to walk along and follow a line that is painted on the ground? Simple, right? You might be able to follow a line without giving it much thought, but how could a robot do that? In this project, you will build your own automatic line-following robot that can race around a track that you create. This technology has plenty of real-world applications—maybe one day you could help design self-driving cars! Read more

This project is a follow-up to the Science Buddies project , which shows you how to build a basic infinity mirror using light emitting diodes (LEDs) and arts and crafts materials. What if you wanted to build an infinity mirror that could change colors, like the one in Figure 1? Figure 1. A color-changing infinity mirror. You can do this by using special RGB (red, green, and blue) LEDs. Just like the pixels on a TV or computer monitor, an RGB LED actually contains three distinct color… Read more
