What Makes Something Alive?

Active learning works for this topic because Year 4 students learn best when they can see, touch, and discuss real examples. Movement and observation of objects help them move beyond simple definitions to deeper understanding of what it means to be alive.

Sorting Carousel: MRS GREN Classification

Prepare trays with 20 objects: live worms, dead insects, seeds, robots, leaves, stones. In small groups, students use MRS GREN checklists to sort into living, dead, non-living piles. Rotate trays every 10 minutes, then share and justify one tricky item as a class.

Differentiate between living, dead, and non-living things using specific criteria.

Facilitation Tip

During the Sorting Carousel, circulate with a checklist to prompt students to justify their classifications using all seven processes, not just movement.

What to look for

Present students with images of various items (e.g., a bird, a toy car, a fossil, a mushroom). Ask them to write 'L' for living, 'D' for dead, or 'N' for non-living next to each item and provide one reason for their choice.

Observation Logs: Live vs Still

Provide magnifying glasses and charts. Pairs observe a snail, plant clipping, and plastic toy for 10 minutes, ticking off MRS GREN evidence. Compare logs in plenary, noting what proves 'alive now'. Extend by predicting changes if conditions alter.

Analyze how a rock is different from a plant based on life processes.

Facilitation Tip

For Observation Logs, provide fresh plant samples and dead leaves so students can directly compare subtle signs of life like wilting or color change.

What to look for

Pose the question: 'Imagine a plant could not excrete waste. What would happen to it and why?' Facilitate a class discussion where students use their understanding of life processes to predict the outcome.

Prediction Chains: Process Failures

Distribute cards naming life processes. Whole class brainstorms effects of failure, like no respiration equals death. Chain predictions on a board, then test with wilted vs fresh plants. Groups illustrate one chain for display.

Predict what would happen if a living thing could not carry out one of its life processes.

Facilitation Tip

In Prediction Chains, limit the chain to three steps to keep the discussion focused while still encouraging creative reasoning about consequences.

What to look for

Give each student a card with one of the MRS GREN letters. Ask them to write the full name of the life process and one example of an organism demonstrating it. For example, for 'G', they might write 'Growth - a baby human getting taller'.

Role-Play Stations: Life Processes Demo

Set four stations for groups to act out MRS GREN: mime growth, sensitivity to light. Record videos on tablets. Regroup to watch and score accuracy against criteria, refining performances.

Differentiate between living, dead, and non-living things using specific criteria.

Facilitation Tip

At Role-Play Stations, assign each group one life process and ask them to demonstrate it physically, then freeze while others guess which process they represent.

What to look for

Present students with images of various items (e.g., a bird, a toy car, a fossil, a mushroom). Ask them to write 'L' for living, 'D' for dead, or 'N' for non-living next to each item and provide one reason for their choice.

A few notes on teaching this unit

Experienced teachers approach this topic by starting with clear criteria and revisiting them often. Avoid letting students rely only on movement as a sign of life, and instead guide them to look for multiple processes. Research shows that hands-on classification and role-play help students internalize abstract concepts like respiration and excretion, making them more likely to retain the information long-term.

Successful learning looks like students confidently classifying objects by the seven life processes and explaining their reasoning. They should use terms like respiration and excretion accurately when discussing whether something is living, dead, or non-living.

Watch Out for These Misconceptions

• During Sorting Carousel, watch for students who classify wind-blown leaves or battery toys as living due to movement alone.

  Use the Sorting Carousel checklist to have students verify if the object performs all seven processes. Ask groups to present why they included or excluded each item, forcing them to defend their reasoning with evidence.

• During Observation Logs, watch for students who overlook plant growth or sensitivity to light.

  During the Observation Logs, provide a timer for students to observe the same plant over 10 minutes, noting changes in position or leaf orientation. Ask them to circle any subtle movements or reactions to ensure they notice processes beyond obvious traits.

• During Role-Play Stations, watch for students who believe dead things were never alive.

  In Role-Play Stations, include a dried leaf and a live leaf side by side. Ask students to act out how each one demonstrates life processes differently, then discuss what changed from live to dead.
