Level 3 · Science S3.1

Cells

All living things are made of tiny cells, and each part of a cell has a job.

Learn the signs of life, look at cells through a drop of water and a microscope, and draw plant and animal cells. See how special cells suit their jobs, how cells join into organs, how things spread by diffusion, and how one cell can be a whole living thing.

For parents and teachers

For learners who can read a page alone and use the four operations. In many schools this fits children of about 11 to 13, and older learners can use it too. Activities use water, jars, beans, cloth and dough. Nothing is tasted. Anyone who looks through a lens or a drop of water must never point it at the Sun. A learner can work alone: every exercise has its answer and the reason for it.
