Each book includes a science experiment that lets readers further explore the topics. I bet that after reading these books, you won’t look at the sky the same way again.

May flowers always line your path and sunshine light your day.
May songbirds serenade you every step along the way.
May a rainbow run beside you in a sky that’s always blue.
And may happiness fill your heart each day your whole life through.
