Following the success of the Little Book of Investigations, this book goes one step further in size, scale and scope. It covers explorations indoors, outside and in the local community, from the water in the tap, the dust on the floor, the mud in the garden, to exploring connections, constructions and other early technological experiments. The natural world, minibeasts, weather, growth, change over time and making changes to materials and the environment are included in this easy to use book. The inventive activities will all also provide opportunities for children to sustain their thinking with other children and adults while using the skills of observation and experiment.
