Alka-Seltzer Experiments
http://www.alka-seltzer.com/as/experiment/student_experiment.htm Alka-Seltzer Experiments Not only does Alka-Seltzer help you to feel better fast, it's also pretty cool to watch! The familiar fizzing you hear when you drop an Alka-Seltzer tablet into a glass of water is the result of a chemical reaction. It's also the perfect tool for demonstrating some very nifty science principles; things like the factors affecting the rates of chemical reactions, or the colors produced by a chemical reaction. The Effect of Temperature on Rate of Reaction | The Effect of Particle Size on Rate of Reaction | The Effect of Concentration of the Reactants | Factors which effect the rate of chemical reactions | Chemistry Colors - Mix and Match | It's Chemical! | Why does Alka-Seltzer | Alka Rockets | |

Crossword on Simple Chemical Reactions 7F
http://www.docbrown.info/ Crossword on Simple Chemical Reactions Quiz - QCA 7F KS3 science chemistry at Doc Brown's Although the site centres around UK science courses, the study notes and revision quizzes should prove useful for chemistry revision of any science course taken by 11-18 year old school-college pupils-students around the English speaking world. I've tried to indicate the US grade levels and other countries if supplied with the information. |

QCA Scheme of Work: Science KS3 Unit 7F
http://www.standards.dfes.gov.uk/schemes2/secondary_science/sci07f/ KS3 (England) Science Unit 7F: Simple chemical reactions This unit is part of the scheme of work the shows how the science programme of study (PoS) for key stage 3 can be managed more easily. The scheme is not statutory; you can use as much or as little as you wish. You could use the whole scheme or individual units. The sections on ?sing this scheme?and ?equencing the units?can help you to decide how you want to use the scheme. You may also wish to combine these units with units from another subject. The ?ombining units?section gives information on exploiting powerful links between subjects. 1. What is a chemical reaction? 2. How do acids react with metals? 4. How do acids react with carbonates? 5. What new substances are made when materials burn in air or oxygen? 7. What is produced when fuels burn? 8. What is needed for things to burn? |
