Marvelous MachinesMarvelous Machines
From the time kids are very young, they seem to love things that go. This week, we’re digging into that curiosity with a collection of puzzles, stories, activities, and more—all about Marvelous Machines. There are lots of reasons to support this fascination. For younger kids, exploring how things work can help build vocabulary and imagination. For older kids, machines can be an introduction to engineering and help develop essential life skills. Creativity, for example, is inherent to the design process, while optimism is important in believing that every machine can be improved. Communication and collaboration help engineers find those areas for improvement, and they may also need to make ethical considerations as they think about any unintended consequences or challenges. We hope these activities inspire and spark your kids’ curiosity to learn more!
