1IntroductionThis presentation includes some samples from our Interactive KS3 Chemistry Software. The two CD-ROMs aim to cover the requirements of KS3 Chemistry through a series of high quality informative slides, diagrams, animations and interactive questions.To fully access the benefits of the software, you will need to have the MACROMEDIA FLASH PLAYER 7 (or later) installed on your computer/network. This program is FREE and downloadable from the Macromedia website at:If you have any problems using this software, please do not hesitate to contact us.Tel:Fax:Web:

This is done using numerous high quality animations, interactive exercises and a total of over 600 slides.
6Draw a diagram for the apparatus shown in the photograph. Exercise: ApparatusDraw a diagram for the apparatus shown in the photograph.
7Exercise: Particles 1. Which three particles make up an atom? 2. Which two particles are found in the nucleus?3. Which particle has a positive charge?4. Which particle has a negative charge?5.

11CFCs CFCs in the atmosphere are known to deplete the ozone layer. They are a group of man-made chemicals that were first produced in the first half of the twentieth century.CFCs usage includes as coolants in refrigeration systems and air conditioners, as solvents to clean electronic components and in the manufacture of plastic foam.Countries are now trying to limit the production of CFCs because of their adverse effect upon the ozone layer.Even though worldwide production of CFCs has decreased, because the CFCs remain active in the atmosphere for many years it is expected that the ozone layer will only recover by the middle of the twenty first century.

13Copper & SilverAbove you can see some copper powder that has just been added to silver nitrate solution. When copper is added to a solution of silver nitrate, copper will displace the silver from the solution.
21Chemical ChangesIn chemical changes a new substance is made and the change is hard to reverse.Examples of chemical changes?Making glassBurning coalRustingImage copyright JSH Education LtdBoiling an eggBaking a cakeIs eating food a physical or chemical change? Discuss!
22DiffusionImage copyright JSH Education LtdWe can use potassium permanganate crystals added to water to study diffusion.
23What factors affect the rate of a reaction? higher concentrationlower concentrationImage copyright JSH Education LtdIf you increase the concentration of the reactants, there is more chance of the particles colliding so the rate of reaction increases.
