The questions in this book were written to support the teaching of Edexcel iGCSE. However the majority of them are also suitable for GCSE.
They are at a range of levels, from simple practice to more complex, thought-provoking challenges. The majority of problems should stretch and challenge the reader.

""Some of the questions really made my top set think."
"Great for setting prep."
"Once I'd done these I really felt ready for my iGCSE exams.""

Electricity and magnetism are a huge part of our lives, and we often take these forces for granted. Before eBooks, computers, and remote control toys, though, scientists put a lot of effort into discovering how they worked, and how they could capture that energy to make our lives easier. Through their explorations, the connection and relationship between electricity and magnetism was discovered. Scientists and inventors found ways to bring electricity to the people who wanted and needed it. And, while we benefit from the discoveries that have already been made, there is always more to learn Whether you try the activities in this book as a fun unit study, as part of your homeschool science lessons, as an extra project for school or a science fair, or just to discover new things, you'll get an up-close look at electrical and magnetic forces. Enjoy the SHOCKING discoveries you make as you enjoy the PULL of science

Car Models that Zoom launches high speed building, creativity, learning, and fun. Make a car model in minutes. Start with a cardboard frame and add motors to create hovercraft, solar-powered models, cable cars, and more. Explore ways to power your models with balloons, rubber bands and electric motors. In the classroom and at home kids learn science fundamentals as they fast prototype their models to get them going farther and faster. They are encouraged to be creative and try their own ideas. Materials are inexpensive and easy to find. The models have been tested by the author in his teacher workshops in 25 countries around the world.

These giant books containing exciting projects and experiments take a hands-on approach to science concepts. Hundreds of simple and easy experiments explore the various scientific principles behind natural phenomena like friction, centrifugal force, and the underlying laws of physics that help make machines work. These fun yet practical experiments make it easy for anyone to become a rocket scientist Sound and light may seem like things we know everything about, but by conducting these easy to navigate science experiments using these seemingly straight-forward concepts, young learners will see that there is "much" more than meets the eye. Through these informative and easy to conduct experiments and activities, budding scientists will discover the interesting and often-changing characteristics of materials in their everyday world.

This best-selling classic provides a graduate-level, non-historical, modern introduction of quantum mechanical concepts. The author, J. J. Sakurai, was a renowned theorist in particle theory. This revision by Jim Napolitano retains the original material and adds topics that extend the text's usefulness into the 21st century. The introduction of new material, and modification of existing material, appears in a way that better prepares the student for the next course in quantum field theory. Students will still find such classic developments as neutron interferometer experiments, Feynman path integrals, correlation measurements, and Bell's inequality. The style and treatment of topics is now more consistent across chapters. The Second Edition has been updated for currency and consistency across all topics and has been checked for the right amount of mathematical rigor.

There are four books in the series: Electricity and Magnets , Sound and Light , Forces and Motion and Matter and Materials . Each title contains 20 tried and tested experiments. The experiments are all safe to do, use household materials, are manageable but absorbing, and offer rewarding results. Readers are told how long each experiment lasts, what materials are needed and what the results mean. Eye-catching illustrations and engaging text make this the perfect book for the budding scientist!

Simple machines make all of our lives easier on a daily basis. In this informative book, young readers will be introduced to many uses of the lever, pulley, inclined plane, wheel and axle, screw, and wedge.
