With Science in a Jar, kids and grown-ups need only gather a jar and a few other inexpensive and readily available household objects to begin investigating and confirming the science at work all around them. The 35+ experiments included cover various scientific disciplines: life science, earth science, physical science, weather, and more. Some activities, like creating a cloud in a jar, are quick experiments that can be performed over and over again. Others, like the earthworm habitat, will be enjoyed over time. Science in a Jar also features several projects that help demonstrate how science and art intertwine-the sometimes overlooked "A" in STEAM! Each experiment is headed by a supplies list and difficulty level, as well as a short description of the project to be undertaken and the scientific principles with which the readers will interact. Directions and photographs guide readers through the scientific method in each experiment, while short features offer multileveled reading opportunities with explanations of terms, interesting quick facts, and brief descriptions of how scientists apply the specific concepts that readers just witnessed in the larger world today. In addition to providing readers with a better understanding of basic scientific concepts, Science in a Jar ignites curiosity, increases confidence to investigate scientific concepts, and fosters a love of science.
