how to measure forces

We can measure forces with a force meter.

NON-CONTACT FORCES

 GRAVITY:
If you dont have gravity you stay flying.

STATIC ELECTRICITY:
It atracts hair to charged objects.

MAGNETISUM:
To imans stay atracted together

PERIODIC TABLE

Im going to help you to make you learn a little bit more about the periodic table. http://www.periodictable.com/

I´ve learnt a lot I think you will learn to.

LITTLE QUIZ ????

1.CAN A SATURATED LIQUID BE DISSOLVED?
2.NAME TWO SOLIDS THAT CAN'T DISSOLVE IN A LIQUID.
3.WHAT IS A INDIGESTION?
4.WHAT IS A UNIVERSAL INDICATOR?
5.AND WHAT COLOUR WOULD IT BE IF IT WAS UNIVERSAL INDICATOR 7?
6.WHAT IS A SOLVENT?

HERE IS A NICE PICTURE FOR MIXTURES AND SOLUTIONS!!!!!!!!

MIXTURES AND SOLUTIONS!!!

Solutions and Mixtures Before we dive into solutions, let's separate solutions from other types of mixtures. Solutions are groups of molecules that are mixed up in a completely even distribution. Hmmm. Not the easiest way to say it. Scientists say that solutions are homogenous systems. Other types of mixtures can have a little higher concentration on one side of the liquid when compared to the other side. Solutions have an even concentration throughout the system. An example: Sugar in water vs. Sand in water. Sugar dissolves and is spread throughout the glass of water. The sand sinks to the bottom. The sugar-water could be considered a solution. The sand-water is a mixture.

About Chemistry!!!!

If you are looking for basic chemistry information, stay on this site. It's not just for kids, it's for everyone. We have information on matter, atoms, elements, the periodic table, reactions, and biochemistry. If you're still not sure what to click, try our site map that lists all of the topics on the site. If you surf and get lost in all of the information, use the search function on the side of the pages.

OKAY! As we have for ten years, let's start here...

So you're asking, what is CHEMISTRY? Well... Here's our best definition. Chemistry is the study of MATTER and the changes that take place with that matter.

Don't ask us why that matters. It just does. A lot. Everything on Earth, everything in our solar system, everything in our galaxy, and everything in the universe is made up of matter. Matter is the name that scientists
