STEAM problem-solvers and twin mice Sydney and Simon learn about the dangers of pollution-and the power of recycling-in this illustrated chapter book for young readers Last we saw them, Sydney & Simon used science, technology, engineering, arts, and math skills to save wilting flowers in their window box. Now the twin mice are back to apply STEAM thinking to recycling! During a class field trip to the Aquarium, Sydney is upset when she realizes that a green sea turtle has been harmed by garbage that made its way to the ocean. She must convince Simon that even if others don't intend to litter, the garbage everyone puts in a trashcan may accidentally get swept into sewers, streams, rivers, and possibly end up in the ocean. The twins collect data on the trash habits of their household and school and find they are all part of the problem! They need to figure out a way that their family, their neighbourhood, and their school can cut down on garbage production and make better use of their discarded items. Short chapters paired with Peter H. Reynolds's lively illustrations will inspire readers to take a closer look at their recycling habits and implement small changes to make a big difference.
