Book excerpt: Pack up sandcastle-building supplies, sunscreen, and this take-along activity book! In the second book of the Backpack Explorer series from the Editors of Storey Publishing, little beachcombers are encouraged to discover all the wonders of saltwater oceans and freshwater lakes, from identifying shorebirds to learning about the life found in tide pools to listening to the waves and watching the tides. Backpack Explorer: Beach Walk is packed with prompts and activities, including 12 interactive field guides (for shells, jellyfish, and more), sensory scavenger hunts, science experiments such as a Stick Sundial, games, and simple projects including food chain match-ups and driftwood fish. Equipped with a real magnifying glass, stickers, and a beach log for recording shoreline sightings and adventures, this book is the perfect takealong for any beach adventure.
