Bricks

Series: Threads S.
Hardback
A series which encourages readers to take a closer look at some of the products which they see and use every day, by making collections, observations, and trying simple activities. Here, the many kinds of brick are investigated showing how they are made in a factory and from modelling clay. The book tells about some of the many different kinds of brick we use to build houses, factories and bridges and asks questions such as: why do some bricks have holes through the middle? And what happens to bricks when they are fired in a kiln?
