A good science project as part of an introductory electricity course. This project can be used as a science fair project or merely for fun. If you've ever wanted to make your own battery, know is the time, this science experiment will show you how.

How To: Understand what science & why it's important

Chris tells us how to understand what science is and why it's important. If you didn't have science, you wouldn't have any technology! This includes televisions, cell phones, portable devices, and everything else that science relies on. Basically we would be living like we were in the stone age again! Science impacts so many different parts of our lives, and although it's not all the same type of science, it all matters. Take a few minutes to think about what life would be like without having...

How To: Build a simple electromagnet

Electromagnets are super cool to experiment with. In this educational video, Science Bob teaches us about electromagnets - what they are and how to build one of your own. These magnets are are very powerful and make an extremely neat experiment for the science fair. Electromagnets are unique in the sense that they convert electricity into magnetism. Try this experiment with your kids for a unique science lesson.

How To: Extract DNA from a banana

Check out this instructional science video that demonstrates how to extract DNA from a banana. This is a great science experiment for students and kids to perform by following the simple step by step instructions outlined in this science tutorial video. Extract real DNA from a banana and analyze it under a microscope.

How To: Detect disease with Nanotechnology

Check out this instructional science video that demonstrates how to detect disease using Nanotechnology. From the Oregon Museum of Science and Industry, this is a demonstration about a new technology that lets us detect diseases earlier and faster than we could before. Science has invented this new technology that can test for several diseases at the same time.

How To: Make a water compass

Have you ever gotten lost and wanted to reorient your sense of direction? Check out this instructional science video to learn a very easy way to make a compass. All you need is a magnet and a bottle cap. This is a great science experiment to perform with the kids. Make your own compass by following the simple instructions in this science tutorial video.

How To: Walk on non-Newtonian fluid

You may remember the recipe for a basic non-Newtonian fluid from grade school science experiments (one part water to one and one third part corn flour or cornstarch), but those trials probably stopped at squeezing the mixture in your hands. While a regular fluid's viscosity wouldn't allow you to walk on it, a little bit of technique and the magic of physics will have you walking on a non-Newtonian fluid as well as Jesus. This video science experiment shows how to use 50kg of corn flour/cornst...

How To: Perform an ice-cube trick with sodium chloride

Think you can lift an ice-cube with nothing but a piece of string? In this cool how-to science lesson, Steve Spangler shows us how to do it, and explains what happens when salt is put on ice. We all know that salt is used to melt ice and snow, but do you know why? Leave it Steve Spangler to turn this basic science lesson into an after-dinner trick you'll use to amaze your friends.

How To: Make a cartesian diver

In this two-part science tutorial, learn how to make a cartesian diver, easily & inexpensively. A Cartesian diver, sometimes known as a Cartesian devil is a classic science experiment, named for René Descartes, which demonstrates the principle of buoyancy (Archimedes’ principle) and the ideal gas law.

How To: Construct a model windmill and calculate its power

This science video demonstrates how to construct a model windmill and then calculate its power output. This tutorial also includes a discussion of Energy, Work, Power, Joules and Watts. If you know anything about electricity, you'll be fine with this science experiment. If you know how to be constructive, you'll be fine too. This science lab is not only fun and educational, but you'll have your very own windmill at the end.

How To: Extract DNA from wheat germ

This science video tutorial includes step-by-step instructions for extracting DNA from wheat germ, the embryonic plant attached to the wheat seed. Individual wheat seeds, or kernels, separate readily from the plant. This kernels have a tough outer coating called bran. If you want to know more, just watch this science experiment.

How To: Explore Density, Viscosity & Miscibility with a Colorful Layered Liquid Science Experiment

Ever wonder why Jupiter has those colored bands across its surface? Jupiter's enormous mass is made from an array of different liquids, and those fluids do not play well together because of their different makeup. All of the hydrogen- and helium-based fluids are thought not to be miscible, which means that they aren't homogeneous in nature, resulting in strikingly beautiful bands across the planet's surface. But what about viscosity and how that correlates to the development of planets? What ...

How To: Do a science experiment with dry ice

In this tutorial, Science Bob shows us how to do a science experiment with dry ice. First, take a block of dry ice and place a quarter on top of it. Make sure you are using rubber gloves when you do this, it's dangerous to touch gloves with your bare hands. When you press the quarter down, it will cause it to vibrate very quickly. You can put any type of metal on top of the dry ice and it will make different noises. This is only one of the many things you can do with dry ice. You can also use...

How To: Do a jumping flame science experiment

This nifty little science experiment is sure to be one that will not only educate, but entertain as well. This tutorial shows you how to do a jumping flame experiment using nothing more than a candle, a flame, and some smoke to help the flame travel. It's perfect for those young and old and is easy to perform. Enjoy!

How To: Tell if an egg is raw or boiled with Krampf

You can easily tell if an egg is raw or hard boiled without breaking the shell, as long as you know a little science. This experiment uses physics to show how if you spin an egg you can tell if it's insides are viscous or solid! Thanks Happy Scientist Robert Krampf for this great tutorial on the science of eggs and physics of rotation.

How To: Make copper metal from copper sulfate
