Optics: A Fairy Tale by Sarah Allen

Standard

opticsOptics: A Fairy Tale by Sarah Allen, e-book, 23 pages, published in 2013.

The woods surrounding Isabelle’s village are full of monsters. The villagers know it is not safe to enter the woods, but Isabelle must go to cut some wood to help her family survive. She discovers a monster stuck in a tree, and helps it. In return she is shown a special mirror in which she can capture the monsters’ souls so that they will stop terrorising her village.

This book introduces the properties of convex and concave mirrors and lenses in a fun and entertaining way. The mirror in the story is a large spherical concave mirror, like a big bowl on its side. In this mirror, Isabelle can see and trap the souls of the monsters that have chased her. She sees that the images of the souls change size and location when the monsters move closer to or further away from the mirror’s surface, and on the concave side, the images are upside-down. Through the telling of this story, I learnt a bit about optics. Being able to put this information into the context of a story will help me to remember the properties of concave and convex mirrors, and in turn, lenses.

There is a small section at the end of the story that explains these concepts in simple language. It covers the centre of curvature, focus and image location with simple diagrams to aid understanding.

Optics: A Fairy Tale is part of an educational series by Sarah Allen. This blend of fairy tale and physics is suitable for high school students and up. It simplifies some optics basics, helping to prepare physics students for more complex concepts.

Fluid Mechanics: A Fairy Tale by Sarah Allen

What an interesting concept! Learn about physics through the telling of a fairy tale. The first section of the book tells the fairy tale, while the second part goes over the physics concepts that were found within the story.

Once upon a time there was a princess… and she rocks! She becomes queen, and goes off to face the wizard that has stolen her baby daughter, and put her beloved husband into a never-ending sleep. Her husband’s brothers help her out in her quest, giving her a magical golden ball and a silver boat.

The fairy tale showed the Archimedes’ Principle, Buoyancy Force, Bernoulli’s Principle and Archimedes’ screw in action. The story was well written, and I enjoyed it. I also liked the Queen, who shows innovation, perseverance and courage along her quest. She faced the wizard, and solved his conundrum, using fluid mechanics, allowing the reader to explore an example of these concepts. They were then explained more fully in the second section. Simple diagrams were used to help illustrate the physics. This is a great way to introduce physics to younger students, or anyone having difficulty getting their heads around it. I found it was quite easy to understand the science in this format, and it hardly seemed like learning at all!

Suitable for kids from upper primary through high school and beyond, Fluid Mechanics: A Fairy Tale is a fantastic introduction to this interesting subject. More Sarah Allen science books are available through Amazon.
