Secondary pupils can “train” a teenage athlete - there’s a choice between swimmer, sprinter or basketball player - and improve their science at the same time. Beat the Best is an excellent CD-Rom from the British Heart Foundation. You watch video sequences as you improve your understanding of veins and arteries, red and white blood cells and gaseous exchange in alveoli and capillaries. Then you apply your knowledge as you set up an exercise and diet regime for the on-screen performers, and check your own health habits at the same time. Beat the Best can be ordered from the distributors Dataforce, quoting code G211.
