How To: Properly balance chemical equations
In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need to even them out. To do this, you need to change the coefficients within the equation. These change the total number of atoms inside of a chemical. Once you do this, you will add more to each atom present and the...
How To: Extract DNA from a Strawberry with Basic Kitchen Items
We all know that DNA is pretty amazing, but it's not something that most of us get much hands-on experience with. Even though it's in every living thing around us, we never see it, so we rarely think about it either.

How To: Build a faraday motor
Build a faraday motor with tips from this how-to video. In the early 1800s, physicist Michael Faraday invented the first device to convert electrical energy into mechanical motion. This is an easily built version of his motor. The magnet sets up a magnetic field, and the electrical current through the screw sets up a separate electromagnetic field around the screw. The two fields react and the result is rotation.
