Science experiments are an awesome part of science that allows you to engage in cool and exciting hands on learning experiences that you are sure to enjoy and remember! By working through our science experiments, you will learn about science in the best possible way – by doing things yourself! Sure, you can learn a lot in science class or by doing your homework, but there's nothing quite as much fun as learning by getting your hands dirty by doing some safe & fun science experiments! Specially chosen to appeal to kids in grade 7 & 8, each experiment answers a particular question about a specific category of science and includes an introduction, list of the materials you need, easy-to-follow steps, an explanation of what the experiment demonstrates as well as a learn more and science glossary section! Each of these easy-to-understand sections helps explain the underlying scientific concepts to kids and will inspire them to create their own related experiments and aid in developing an inquisitive mind. Amongst many others, you will use red cabbage as an indicator to test if a substance is an acid or base to understand how chemical analysis works, construct a rocket to see how objects fly, use the power of air pressure to crush a tin can, and make an electrical light bulb to learn about the resistance in electrical conduits! Other fun experiments include using iodine to test for the presence of starch in foods, using chromatography to predict the 'fall' colour of a green leaf tree, making a humidity detector to predict the possibility of rain, producing a huge heap of foam with an exothermic reaction, proving the rotation of the earth with Foucault's pendulum, making an inclinometer or dipping compass, making a simple astrolabe to measure the altitude of objects in the sky, measuring the humidity level with your own hygrometer, Build your own rain alarm, foxhole radio, telegraph, rheostat, Franklin bells device, biosphere, Snellen chart, Von Frey device, air pressure rocket, kaleidoscope and many, many more! The 60 projects contained in this science experiment e-book cover a wide range of scientific topics; from Chemistry and Electricity to Life Sciences and Physics... there are even experiments on earth science, astronomy and geology all designed for young students from grade 7 to 8! With this book, you are sure to find a project that interests you. When you are interested in a certain science topic, you will have more fun, and learn more, too! Science can be real simple and is actually only about understanding the world you live in! Science certainly does not need to be complicated formulas, heavy text books and geeky guys in white lab coats with thick glasses. Science experiments are an awesome part of science that allows you to engage in cool and exciting hands on learning experiences that you are sure to enjoy and remember! By working through the science experiments in this book, you will learn about science in the best possible way – by doing things yourself. Designed with safety in mind, most of the items you will need for the experiments, such as jars, aluminium foil, scissors and sticky tape, you can find around your home. Others, such as magnets, lenses or a compass, you will be able to buy quite cheaply at a hobby shop or hardware store.
