The science in a Topic students’ book Ships provides a range of activities that enable children to develop ideas about floating, balance and stability. There are models to make and test which lead to ideas about the centre of gravity of stable and unstable objects. Ways of propelling and steering ships and the use of pulleys are studied. Instructions for students are well illustrated by drawings and photographs. The teacher has an active role, as indicated in the relevant sections of the Teacher’s Guide, in providing materials and reinforcing the questions that lead the students to investigate, create and find information.
