With real-life inspiring STEM challenges, this series gives KS1 readers the building basics for a variety of projects, including towers, boats, bridges, traps and marble runs. These projects in turn support physical science concepts of forces and motion, energy, buoyancy and simple machines. A child-friendly inquiry approach leads to simple, clear answers for KS1. Fun STEM Challenges encourage students to experiment with, test and learn from their designs. It's perfect hands-on learning to build confidence in all young engineers! Part of the Fun STEM Challenges series.
