1 Introduction This 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: www.macromedia.com If you have any problems using this software, please do not hesitate to contact us.

2 KS3 Chemistry 7E.Acids and alkalis 7F.Simple chemical reactions 7G.Particle model of solids, liquids and gases 7H.Solutions 8E.Atoms and elements 8F.Compounds and mixtures 8G.Rocks and weathering 8H.The rock cycle 9E.Reactions of metals and metal compounds 9F.Patterns and reactivity 9G.Environmental chemistry 9H.Using chemistry The aim of our Interactive KS3 Chemistry CD-ROMs is to cover the requirements of KS3 Chemistry in a comprehensive and stimulating fashion. This is done using numerous high quality animations, interactive exercises and a total of over 600 slides.
6 Exercise: Apparatus Draw a diagram for the apparatus shown in the photograph.
7 Exercise: 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.Which particle orbits the atom? Neutron, proton and electron Proton and neutron The proton The electron
8 Exercise: Which Elements? 1.For the compounds below, write down the names of the elements present. a) NH 3 b) CH 4 c) H 2 SO 4 d) CaCl 2 e) CO f) NaCl g) SiO 2 h) Fe 2 O 3 Nitrogen and hydrogen Carbon and hydrogen Hydrogen, sulfur and oxygen Calcium and chlorine Carbon and oxygen Silicon and oxygen Sodium and chlorine Iron and oxygen
11 CFCs 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.
12 UK Production Of CFCs Comment on the information shown.
13 Copper & Silver Above 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.
21 Chemical Changes In chemical changes a new substance is made and the change is hard to reverse. Making glass Burning coal Baking a cake Rusting Boiling an egg Is eating food a physical or chemical change? Discuss! Examples of chemical changes?
22 Diffusion We can use potassium permanganate crystals added to water to study diffusion.
23 Factors If you increase the concentration of the reactants, there is more chance of the particles colliding so the rate of reaction increases. What factors affect the rate of a reaction? higher concentration lower concentration
24 Settling Gravity causes the sand particles to settle to the base of the beaker.
