First Science STEAM words for Preschoolers! Children love hands on science experiments, and they love learning new words! And in Scientists for a Day, John and Emma get to spend the day with Emma's mom, who is a real scientist! They visit the laboratory, where they don their safety goggles and lab coats. They watch Emma's mom pour a liquid from a boiling flask into a beaker. The steam that rises is a chemical reaction! They also get to see tiny cells through a microscope, and after lunch, they even do a fun experiment of their own! Written with preschool curriculum vocabulary words in mind, each page features one or more science term, all of which are defined on the last spread. Relatable and entertaining, the story ends with Emma and John wanting to grow up to be scientist!
