A visual reader collection that looks at the sourcing of materials of objects we use every day, from aluminum foil to plastic bags. The explanations of polymer science for young audiences are particularly well done here and really dig into the fossil fuel questions younger readers may have. The text is light with vocabulary scaled to match readers’ levels, but inclusive of critical science literacy terms for growth. VERDICT A good addition to libraries looking to expand their environmentalist collection related to sourcing to bridge younger generations.
