Level 4 · Science S4.1
Cells, photosynthesis and respiration
How cells are built, how they work, and how they get energy.
Look closely at animal, plant and bacterial cells, learn how to measure them under a microscope, and follow how substances move in and out. Then see how cells divide, how enzymes speed up reactions, and how photosynthesis and respiration pass energy through living things.

For parents and teachers
For learners who can follow a written argument and have met cells, plants and the body in earlier books. In many schools this fits learners of about 14 to 16, and older learners can use it as a reference. Each chapter takes two or three short sessions. A learner can work alone: every exercise has its answer and the reason for it. The Try it activities use water, salt, a potato, yeast and sugar, balloons and household bottles. Nothing is tasted. An adult should cut the potato, or the learner uses a table knife on a board, and an adult should be near for anything that uses warm water. Experiments that need a microscope, a lamp and special equipment are described as things scientists do, with a household version where one exists.
