Flash, Crash, Rumble and Roll

"Flash, Crash, Rumble, and Roll" by Franklyn M. Branley is a Let's Read-and-Find-Out Science Stage 2 picture book all about thunder and lightening.

All children are curious about thunder and lightening because of how loud and scary it can be. Even as an adult, when lightening strikes, I find myself leaping towards the window to watch the bright lights flash across the sky. It can be magnificent to look at.

During the elementary years, you can take away some of that mystery and maybe some of the fear by explaining the science behind it all. This book is a perfect tool to get you started.

"Thunder comes after the lightening. The lightening is very hot. It heats the air. The hot air expands very fast. It makes sound waves all along the streak of lightening. The sound waves reach you at different times. When the first one reaches your ears, there may be a loud crash. As more and more sound waves reach you, the thunder rumbles and rolls."


There are also some safety tips near the end of the book such as "If you are swimming, get out of the water", "Stay away from the stove and other big metal things", and "If you are outside, go inside."
