📋 What it is
Living things share traits: they grow, use energy, respond to their environment, and reproduce.
🗣️ Coach says
How do you know if something’s alive? Living things all grow, take in energy, react to their surroundings, and can make more of themselves. A rock does none of these; a plant does all four.
🧠 Memory hook
Alive = grows + uses energy + responds + reproduces. All four, or it’s not living.

Why did the sun go to school?
To get a little brighter!
😲 Whoa!
There are more bacteria living on and in your body than there are human cells — you’re a walking ecosystem.
✅ Quick check: A candle flame “grows”, uses energy, and moves. Is it alive?
Say your answer out loud first — then reveal.
No — it fails the full test: it can’t respond meaningfully or reproduce, so it’s not living.
Life requires ALL the characteristics together, not just one or two.
🧪 Try it! (2 minutes)
Look at three things (a plant, a toy, a pet). For each, check the four signs of life. Which pass all four?
