Buoyant Force of Water

Why does a rock sink in water while a gigantic steel aircraft carrier floats? The aircraft carrier is much heavier, but glides along the ocean surface with ease. Clearly, weight isn’t the entire story ...

How to Reduce Friction

Newton’s First Law of Motion states that when an object is set in motion, it will remain in motion until acted on by an outside force. Theoretically, this could mean you could travel at the same speed ...

WiFi Signal Strength

When wireless signals leave a WiFi hotspot and travel to a computer or other wireless device, the wifi signal strength decays as it passes through air or solid objects. This is why a computer may be u ...

Wind Tunnel Experiment

Swiss scientist Daniel Bernoulli is often considered the father of fluid mechanics, and developed a mathematical relationship between pressure and fluid flow in the 18th century. Both liquids and gase ...

Does Leaving Your Computer on 24/7 Eventually Lead to A Slower CPU Speed or More Frequent “Freezes”?

In this experiment, we will discover whether leaving a computer on 24/7 will lead to more frequent crashes, freezes, and an overall slower processing speed. We will be experimenting with 2 brand new, ...

What Is a Compound Microscope?

Optics is a branch of physics that studies the interactions of light with objects. Microscopes, cameras and other transparent “looking devices” use lenses to change the way we see objects. Using magni ...

World's First Energy-Saving Microcontroller Powered Generator

Demostrate digital sensors, or circuits and how you can use them to program things or power a high amount of electricity so you can find a cheap way to charge electricity or use microcontroller techno ...

Encoding Digital Images

Whether you are taking photos with your iPhone, watching a DVD, reading a pdf, or checking out Google images, digital images are everywhere. This is quite amazing because these images require a lot of ...
