Gr 3–6—Science fair partners Charlie and Oliver accidentally activate a time machine that whisks them away to
different ages and places to learn about trash and recycling. A cute, smart, and incredibly informative book about
recycling, upcycling, composting, and other STEAM topics.

A note-taker and a doodler are paired up for a science project that seems them travel through time, gathering information on how humanity has dealt with the problem of trash and learned how to recycle. A few examples are from the distant past, but most are more recent. When the problem of plastic pollution seems too big to face, solutions and innovations are presented - along with the message that scientists and artists are both needed to come up with more ideas. Fun and informative! ( )
