You can read all the books on music and guitars in the world, but that won't make you a great guitar player. You have to actually practise with a guitar to get it right! It is easiest to figure things out by getting your hands 'dirty' by doing! Science works exactly the same way. Yes, you can learn a lot in science class or by doing homework, but there's nothing quite as much fun as learning by getting your hands dirty doing some science experiments! Specially chosen to appeal to kids in grade 3 & 4, 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 make caramel from sugar to understand how chemical reactions works, construct a rocket to see how objects fly, make a self-filling water bowl for pets using air pressure, and make a compass to learn about the attraction & repulsion forces of magnetism! Other fun experiments include Using simple chemistry to make your dull coins shine again, electroplate a nail, make your own homemade perfume, testing the fat and oil content in everyday foods, using the shadows of the sun to tell the time, telling the time with your own water clock, making a rainbow with water and a mirror, using the sun's infra-red rays to cook a potato, mapping how far the sun is from the moon, making your own refrigerator powered by evaporation, making an electrical door bell for your room, making a light bulb shine using a lemon as a battery, learning how to generate electricity by means of induction, study how ants communicate to find their food, testing the effects of acid rain on ocean life, controlling the direction of sound waves by reflecting it with umbrellas, Building your own simple submarine, windmill, pendulum, magnifying glass and many, many more! The 100 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 3 to 4! 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.
