Safe steps in science tests
Suggest and follow safe procedures when exploring and investigating: following safety rules for exploring with the senses, identifying what could go wrong with the equipment or materials in a planned test, adding a safety step to the plan, using equipment carefully and cleaning up
Lesson
Set out your lesson
“A hazard can cause harm. A safety step must match what could go wrong. We will move a spoonful of water onto a sponge, not use hot water or taste materials. If something is unknown, leave it alone and tell the adult. Safety: Adult stays present. Keep water away from outlets and devices. No chemicals, heat, tasting or deliberate smelling. Stop: Stop for spilled water, a cracked cup or an unknown substance. Resume only after adult review; never add hot water.”
Bring to the table
- Plastic cup, room-temperature water, tray and towel
- Clean metal spoon and clean sponge larger than a child’s mouth
- Paper and pencil
Extra for the adult
Worked example. Illustrative example: risk statement: Water may reach the floor and someone could slip. Matching action: keep the cup inside the tray and stop to dry any spill. Answer: this action addresses a slipping risk; wearing a hat would not control that risk.
Optional challenge. Explain why a glass cup would add a different hazard and why plastic avoids it here.
What to notice. Keep the before/after safety list. Note adult supervision, cleanup help and any stopped transfer.

A hazard can cause harm. A safety step must match what could go wrong. We will move a spoonful of water onto a sponge, not use hot water or taste materials. If something is unknown, leave it alone and tell the adult. Safety: Adult stays present. Keep water away from outlets and devices. No chemicals, heat, tasting or deliberate smelling. Stop: Stop for spilled water, a cracked cup or an unknown substance. Resume only after adult review; never add hot water.
Materials: Plastic cup, room-temperature water, tray and towel; Clean metal spoon and clean sponge larger than a child’s mouth; Paper and pencil 1. Before touching materials, list three possible problems: water could spill; a wet floor could be slippery; an unknown material might be unsafe. Add a matching action for each. 2. An adult approves the plan. Put the cup and sponge inside the tray, with the towel ready. State the senses rule: look and touch only approved items; no tasting; no smelling unless the adult explicitly approves. 3. Use the spoon to transfer one spoonful of room-temperature water onto the sponge. Say which safety action you are following as you move the spoon. 4. Look for water outside the tray before a second transfer. If there is any, stop and let the adult help dry it before continuing. Do not create a spill on purpose. 5. Empty the cup with adult help, dry the tray, put materials away and wash hands. Mark each planned safety action used or not needed, and explain why one mattered. Done: The learner names a risk, follows matching controls during two transfers and helps complete safe cleanup. Proof: Keep the before/after safety list. Note adult supervision, cleanup help and any stopped transfer. Stop: Stop for spilled water, a cracked cup or an unknown substance. Resume only after adult review; never add hot water.

Check understanding
- Follow science safety rules when exploring a collection: never taste, smell only when the adult says it is safe, tell an adult about an unknown substance and wash hands afterwards
- Before a test, say what could go wrong with the equipment or materials (e.g. hot water, a glass thermometer, spilt water) and add a matching safety step to the plan
- Use equipment carefully during the test, clean up afterwards and explain why each safety step matters
“When your child does a science activity at home — like testing how fast ice melts in warm water — do they think about what could go wrong, follow the safety steps (no tasting, careful with hot water) and clean up afterwards?”
