Genre: Informational

Summary: This book shares about sound. It brings the science of sound to readers in an understandable way. It shares about sound waves, sound barriers, sound energy, ultrasound, and various ways we hear and experience sound (especially through musical instruments.)

Review: I like this book! I think parts of it could be read aloud and then other parts could be read individually. I like how many examples are used, allowing many ways different readers can connect to the show more content. The integrity of science is maintained throughout this book, and the glossary in the back is a way for students to get clarification on definitions if needed. + show less

This book gives a variety of examples to students on how they can see and use sound in their everyday lives. The book explains how sound is all around us and how it affects our lives. There are pictures that visually show the different elements of sound so students can fully understand where sound comes from. The book provides real life examples of people using sound so students can see how it is used in a daily life occurrence. There are so many components of sound that the book talks about show more which makes the book interesting for students. It also provides information about how to make different objects that produce sound which students can make and see how the sound is created from that object. It is very hands on allowing them to have a clear understanding. show less

Two page spreads each containing a project having to do with time. Some are pretty challenging. The principles are not explained fully, but there are other books for that. The later projects are a bit of a stretch because too conceptual. The instructions for the projects are kind of incomplete, but the book compensates by having a large number of pictures.

1. A year long calendar showing duration of day and night.
2. A simple orrery without a drive train.
3. A perpetual calendar, good from 1600 show more to 2299. This kind of design is actually marketed as a desk toy here and there.
4. A paper globe.
5. A time zone cylinder. It is another mechanical computer, allowing the determination of relative time.
6. A quadrant, to determine elevations generally, and also latitude from the elevation of the north star.
7. A sundial.
8. A universal sundial.
9. A nocturlabe.
10. A candle clock.
11. A water clock.
12. A pendulum clock.
13. An electronically driven large face clock, you need to cannibalize a smaller clock from this.
14. Running video images backwards.
15. An activity log.
16. Make your own time capsule.
17. A geologic time spiral, showing the various eras.
18. A potted plant.
19. A project about the speed of light.
20. A project about relativity. show less

This is a book about simple science experiments. I would use this book for younger students, but it has a good lesson in the book called find the light. i thought this would be a great way to show students how plants need sunlight to survive!
