ABSTRACT
This chapter explains that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object. It identifies the effects of air resistance, water resistance and friction that act between moving surfaces. The chapter describes scientific procedures and clear instructions that outline the simple equipment required for carrying out each procedure. It provides National Curriculum assessment indicators and illustrates how to carry out the primary science experiments and what results to expect. Suggestions for adapting each procedure or activity to the special needs and interests of the students are discussed.
