Max and Suzy are bored and wish they had a playground in the garden, can the dynamic duo use their engineering know-how to build a swing, slide, and see-saw? Challenges include: choosing the best material to use, how to measure things, and work out how to test their designs. Next steps at the end of the book detail the engineering behind the story, with hands-on activities for children to experiment with the concepts explained, and find out for themselves how things work.
