Living, Dead or Never Alive? Free KS1 Science Worksheet

What this worksheet teaches

The aim is for children to recognise that some things are living, some were once living but are now dead, and some have never been alive. This sounds straightforward to an adult, but it is a genuinely demanding idea for a five to seven year old. Young children often assume that anything that moves is alive (a car, a river) and that anything still is not alive (a sleeping animal, a seed, a tree). This worksheet uses six carefully chosen items – a plant, a butterfly, a dry leaf, a cut log, a rock and a toy car – so that children meet all three categories and can compare them directly. Sorting them and giving a reason is what moves children from naming to genuine understanding.

The seven life processes, explained simply

Scientists decide whether something is living by checking whether it can do the seven life processes, sometimes remembered with the word MRS GREN: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition. At KS1 children are not expected to know all seven by name, but the idea sits behind the topic. A useful, age-appropriate shortcut is to ask: does it grow, does it need food or water, can it have babies or make seeds, and does it sense the world around it? A plant ticks these boxes; a rock and a toy car never could. A dead leaf or a cut log is the interesting middle case: it cannot do these things now, but it once did, because it grew on a living tree.

Common misconceptions to watch for

Two misconceptions come up again and again. The first is the ‘moving means alive’ idea: children frequently classify a toy car, the wind or running water as living because they move. Gently steer the conversation back to growing, feeding and reproducing rather than movement alone. The second is confusing ‘dead’ with ‘never alive’. A dead leaf and a rock are both still and silent, so children lump them together. The key question to ask is, ‘Was it ever part of something living?’ A leaf grew on a tree, so it was once alive; a rock was never alive. Treating the cut log and the dry leaf as discussion points, rather than right-or-wrong answers, helps these distinctions land.

How to use this sheet at home or in class

Begin by colouring the picture together and naming each item out loud. Then read the tick statements and decide as a pair which things are, or were once, alive. The writing task asks for a reason about one tricky example – encourage a full sentence such as ‘A leaf is dead because it grew on a living tree.’ To extend the activity, take the idea outdoors: a quick hunt in a garden or park for one living thing, one dead thing and one never-alive thing makes the categories real and memorable. The worksheet pairs naturally with later Year 2 work on habitats and food chains.
