Last Minute Science Fair Ideas: Vol 4 – Due In a Week or More

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 50 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 science 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 make a simple astrolabe to measure the altitude of objects in the night sky, make dirty water pure and drinkable to understand how evaporation & condensation works, make beautiful patterns on a wall to experiment with sound waves, and build a ‘Franklin bells’ device for detecting high voltage lightning storms and learn about static electricity!
Other fun experiments include: growing your own crystals along a piece of string, making your own homemade perfume, measuring the extend of creeping soil on hillsides, making a water barometer to measure the air pressure, checking the wind speed with your own anemometer, building your own rain alarm, building your own foxhole radio, sending Morse code signals with your own telegraph, mummifying an orange, growing plants in your own hydroponic garden, testing the effects of acid rain on ocean life, studying the complete life cycle of a meal worm 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.
