# Measure Speed of Something You Make Science Projects (23 results)

Build or improve a moving object and then measure how far or fast it goes. Learn about the science behind movement to make your design go as far or fast as it can.

In this project you will explore the physics of a rocket as you predict its performance, launch it, and measure the actual results. This is rocket science! Read more Science Fair Project Idea Helicopters are fascinating to watch. The spinning rotor blades on top of the helicopter generate lift, allowing it to take off vertically. They can land vertically, too, allowing them to set down in small spaces, such as hospital helipads or on a ship at sea. In this aerodynamics science fair project, you will fly a remote-controlled helicopter and measure how the rate of the rotor's rotation changes as the helicopter hovers and flies up or down. Read more Science Fair Project Idea Before cannons widely replaced them, siege engines were often used by armies to throw large stones and other projectiles to break down castle walls. One of the most advanced siege engines used in the Middle Ages was the trebuchet, which used a large counterweight to store energy to launch a payload, or projectile. The horizontal distance the payload would travel is called the trebuchet's range. Figure 1, below, shows a modern reconstruction of a trebuchet. The range of a trebuchet has… Read more
