For communities in need of clean drinking water, new research using bacteria may offer a simplified, lower-cost method for boosting potable water supplies.
Sometimes, when we buy a new car, it only looks clean. There can be all sorts of contaminants all over that car's paint. A good idea for removing those contaminants is a process known as clay barring. This instructional video will show you how to clay bar a vehicle.
The Fish Contamination Education Collaborative (FCEC) has made this video to reach the public about fish preparation safety, to make su. It's important to prepare fish in a certain way, because some species of fish have contaminants that pose health risks. Those contaminants are stored in the fatty portion of the fish, so by cleaning and cooking the fish in a certain way, you can reduce your exposure to those toxins.
In this how-to video, you will learn how to use a clay bar for paint decontamination on your car. To clay, make sure you use a brand new bar.

In this video we learn how to balance chemical equations using a teacher's guide. A chemical equation is a brief way of summarizing what happens inside of a chemical reaction. When you mix up two different chemicals, they will create new types of chemicals in the equation. You have to take these new chemicals into equation when you are trying to balance it out. The mass on both sides must be the same as well as the number of different chemicals on each side of the equation. Try out practice e...
Windborne microbes shifting in the snows of the great ice sheet of Greenland may be able to neutralize some of the industrial contaminants oozing out of the melting ice.
n this tutorial, we learn how to balance chemical equations. This is a straight-forward concept to balance out both sides of the equation of chemicals. To start, you will need to analyze how many atoms in each chemical you have on each side. Once you do this, you will need to find what you can multiply by on each side to make them equal to the other side. Once you do this and have equal atoms on each side, then the equation will be equal. Remember that you cant have a half of an atom, so that...
A new study casts real suspicion on the possibility of life on Mars. Why? It seems the surface of the planet may be downright uninhabitable for microbial life as we know it.
In this video we learn how to balance chemical equations properly. What is a chemical equation? It's a statement that uses a chemical formula to show identities and relative amounts of the substances involved in a chemical reaction. To balance an equation out you must have the same number of atoms on both sides of the chemical equation. Or, you must have the same amount of mass or matter on both of the sides. Once you have these balanced out so they are the same then you will have it complete...
Olivia and Andrea created a song to the tune of "I'll stand by you" by the Pretenders to teach you how to balance chemical equations. A chemical equation requires coefficients in order to be balanced. You can balance a chemical equation by making use of the Periodic table. The example reaction in the song is that of aluminum and oxygen to produce aluminum oxide (Al + 02 -> Al203). You can systematically add coefficients to the reactants and products to balance the equation. A chemical equatio...

Glowing substances have always held a powerful appeal to people, and making new ones can be a lucrative business. If you need some glow powder for a project of yours, watch this video to learn how to make DIY glow-in-the-dark powder out of normal household chemicals.
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...

In this video, we learn how to balance chemical equations using a simple method. Start out by writing your two chemicals next to each other. After this, you will need to write out how much of each atom each of the chemicals has. Now you will have a better idea of how you need to balance out each of the different equations. Make a chart of all the elements that are involved, then you can solve it. Use simple addition to add together the atoms of each and then write out the correct answer in th...
In this video we learn how to balance chemical equations the fun way. First, remember that matter cannot be created or destroyed. Take two different types of chemicals and put them on opposite sides of the equation. If you have more mass on one side than the other, these will not balance out. Once you have equal amounts of mass on both of the sides, you will be able to balance the chemical equation. Remember this rule whenever you are balancing out chemical equations. Use visual markers to he...

In this tutorial, we learn how to balance chemical equations. The first thing you want to do is to draw a graph and label one side reactants and the other side products. Go through each of the atoms that are in your equation on both sides. Write out how many atoms are in each chemical. Then, find a common multiple that will give you and equal amount on each side of the equation. Continue to do this same for all the chemicals in your equation, then when you are finished write it out. Now you w...
