Motion Series
- Shedding Light on Motion Overview
- The Shedding Light on Motion series is a visual treasure trove of demonstrations, animations, and explanations of all things Motion.
  From the production of visual effects in movies, to sport, to car safety, to transport (including rockets, planes, and trucks), our knowledge of the physics of motion has completely transformed our world.
  So check out the incredible Shedding Light on Motion series and bring your students up to speed on this topic the easy way!
STAR LAWS Series
- STAR LAWS Overview
- Hello there!
  The word astronomy comes from the Greek words astron which means star and nomos which means “law”. Astron nomy therefore translates literally as STAR LAWS.
  Astronomy is the study of the laws of nature that govern how stars and other bodies in space appear to move across the sky, how they form, and how they change over time.
  The STAR LAWS series is perfect for young Padawans everywhere.
  These ARE the videos you're looking for!
Atoms Series
- Shedding Light on Atoms Overview
- "How do we know about atoms if we can't even see them?"
  
  This is by far the most common question we are asked as Science teachers. The Shedding Light on Atoms series brilliantly answers this question, as well as many more!
  
  The series teaches students not just what we know about atoms, but also how we know what we know about atoms.
  
  No other resource even comes close to covering all the essentials of Chemistry in such a brilliant way!
Energy Series
- Shedding Light on Energy Overview
- The Shedding Light on Energy series allows teachers to teach the topic of Energy without actually using much energy.
  Energy is everywhere. It surrounds us and penetrates us; it binds the galaxy together!
  So train up your students in this all-important topic using this outstanding series.
Heat Series
- Shedding Light on Heat Overview
- The Heat is on in your classroom! This series allows you to stay cool while you teach the topic of Heat.
  Using highly engaging visuals and outstanding explanations, the Shedding Light on Heat series teaches students everything that they need to know about heat.
Light Series
- Shedding Light on Light Overview
- Come with us from the swimming pool into space and from the depths of the ocean to the end of the rainbow where we shed some light on light! This 6-part series covers your whole light course, from reflection to refraction to human vision and more.
  How good is this series? Your students will soon see!
Sun and Earth (Climate Science) Series
- Shedding Light on the Sun and Earth Overview
- This series introduces students to the basics of climate science. We examine what causes seasons, how the movement of the sun across the sky affects the renewable-energy industry, what causes winds, how the climate of a region is affected by its proximity to oceans, and a whole lot more.
  It's the series you need in the current climate!
Electricity Series
- Shedding Light on Electricity Overview
- Electricity has completely transformed our world and millions of people are employed in industries that are directly related to its production and its use. This series covers all the essentials of electricity.
  High Voltage Education!
Acids and Bases Series
- Shedding Light on Acids and Bases Overview
- Though many people are not aware of it, acids and bases play a huge role in every aspect of our lives. They can be found everywhere, from our farms to our kitchens and from our power stations to our industrial plants.
  This series explains what acids and bases are and how the chemical reactions they undergo are a part of our everyday lives.
Nuclear Radiation Series
- Shedding Light on Nuclear Radiation Overview
- Nuclear Radiation can be very dangerous but it can also be very useful to us.
  This series makes it easy to learn all the essentials of nuclear radiation, including
  • atomic structure, isotopes, and nuclides;
  • what alpha, beta, and gamma radiation are and how we have learned to harness their power and;
  • the concept of half-life.
