Sound and light aren’t just sensations picked up by our senses—they’re examples of science at work in the wonderful world around us! Budding scientists will delight in the text’s age-appropriate experiments, which are made easy through step-by-step instructions and photos. Each experiment is accompanied by a question-and-answer feature that answers common questions encountered while experimenting, and a concluding quiz tests reader’s knowledge of these important science concepts.
Have you ever wondered how a telescope brings objects closer or how cameras take pictures? How boats float or aeroplanes fly? All of these seemingly complicated things can be explained by basic science. With the help of this book, you will construct many weird, wonderful and wacky experiments that you can have hours of fun with! Is the deadline for your science fair project quickly approaching? Not to worry, the 'Last Minute Science Fair Ideas’ series is written in an easy to follow format that will guide you to create an exciting science project for the upcoming fair. The science projects in each of the books of this 4-volume series are conveniently sorted according to the approximate time required to complete each experiment. 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 1 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! Amongst many others, you will use the shadows of the sun to tell the time to understand how the earth rotates, construct a simple water turbine to see how hydro power is generated, make beautiful patterns on a wall to experiment with sound waves, and let a light bulb shine using a lemon as a battery to learn about electricity! Other fun experiments include making a kaleidoscope, periscope, telescope, intruder detector, doorbell, relay, fruit powered battery, recycled paper, cold pack, smoke bomb, water turbine, air pressure rocket, camera obscura, insect trap, water clock, water purifier, light bulb, inclinometer, sun dial, moon box and many, many more! When making these gadgets, you’ll discover that science is a part of every object in our daily lives, and who knows, maybe someday you will become a famous inventor 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 store.
