We celebrate the Week of the Young Child during April 12th-18th, 2015. This is the perfect opportunity for early childhood teachers, parents, librarians etc. to look at how they can incorporate science, technology, and math (STEM) into early childhood classroom experiences this week. Young children are naturally curious about the natural and physical world around them. STEM investigations provide opportunities for young children to observe, compare, contrast, build, be creative, develop critical thinking skills, communicate and collaborate with their peers. The following photos are from STEM lessons I have conducted in early childhood classrooms, as well as photos taken during STEM teacher training workshops for early childhood educators. Suggested early childhood STEM explorations include: block building, building 3-d structures with readily available materials, building boats, designing and building ramps to explore force, motion, and energy concepts, exploring patterns and shapes in nature and in man-made objects, incorporating age-appropriate technology in the early childhood classroom such as rulers, pan balances, magnifying lenses, simple microscopes, digital microscopes, Nabi Junior, levels, and more. I have found that early childhood teachers are really excited about incorporating STEM explorations into their classrooms on a daily basis. For more information on the STEM and Science early childhood teacher training workshops I offer worldwide, year-round complete the contact form on this website. Hope you will be inspired by the photos of young children and teachers being exploring STEM content and practices.
