Mô Tả

Science certainly does not need to be complicated formulas, heavy text books and geeky guys in white lab coats with thick glasses. Science can be really simple and is actually only about understanding the world you live in!
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 projects in this book, you will learn about science in the best possible way – getting your hands dirty & doing things yourself!
Specially chosen to appeal to kids in grade 7, 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 iodine to test for the presence of starch in foods to understand how chemical analysis works, make a ‘Berlese’ funnel to catch soil-burrowing insects, make a depth indicator similar to the gauges used on ships, and make an electrical light bulb to learn about the resistance in electrical conduits!
Other fun experiments include using chromatography to predict the ‘fall’ colour of a green leaf tree, make your own barometer to measure the air pressure and predict the weather, study what effect high or low temperatures have on a magnet, build your own rain alarm and many, many more!
The 40 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 in grade 7! 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!
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…
