Scientist — a step-by-step lesson for grown-up and child
This lesson teaches the scientist’s loop — observe, guess, test, look again — and runs a first experiment with jars and a spoon.
What is this?
A scientist is a discovery helper who asks "why?" and finds answers by testing carefully.
What does it mean?
Scientists work in labs, outdoors and in space. They watch closely, make a guess (a hypothesis), run experiments, measure what happens and share results with other scientists.
What does the child need to know?
The scientific loop in child words: LOOK, GUESS, TRY, LOOK AGAIN. Guessing is not cheating — it is the first step of every real discovery.
Why this matters
The scientist mindset is the gift that keeps giving: "let’s find out" beats "because I said so", and a flopped experiment becomes "interesting!" instead of failure.
What it teaches
Curiosity routines, guess-before-test inhibition (thinking before doing), observation vocabulary, outcome reasoning, and flop-resilience.

Say this to your child
“"A scientist looks, guesses, tries and looks again. If we wonder about something, we can be scientists too: we guess first, then we find out!"”
Step by step
- Show the card: "This is a scientist. Scientists find out why things happen by testing them."
- Find the tools: what might be in those flasks and papers? "Scientists write everything down."
- Teach the loop with your hands: eyes (look), finger to chin (guess), hands (try), eyes again (look again!).
- Explain the golden rule: "A guess is a good beginning. Scientists guess FIRST, then test — the test tells the truth."
- Run the three-jar experiment now: guess, tap, listen, compare.
Look closer at the picture
Ask: what is the scientist holding or mixing? What might be inside the jars? Is the scientist writing something down? What colour is the "science" on this card?
Ask your child
"What does a scientist do first — guess or test?" "What are YOU wondering about this week?" "What happened in our jar experiment? What would you try next?"
What your child can say or do
The loop chant: "Look, guess, try, look again!" And the flop line, borrowed from every lab: "Interesting! Let’s try it another way."
Out in the real world
Scientists are everywhere: weather presenters, bakers testing recipes, gardeners testing soil. When anyone says "let’s test it", name it: "that is science!"
Try it together
Three-jar sound test: jars filled full, half and empty of water. Before tapping: everyone guesses which sounds highest. Tap with a spoon, listen, line them up low-to-high. Then the real experiment: can you play a tune?
Understanding check
Ask: "What does a scientist do first? What comes after the guess? What did our jars show us?" Look-guess-try + a remembered result = pass.
Parent tips
Write down your child’s guesses like a real lab book — being taken seriously fuels scientists. Say "interesting!" to surprises, including messy ones: data is data.
Staying safe
Kitchen-lab rules: nothing gets tasted, goggles (or swimming glasses) for anything splashy, and a grown-up runs any experiment with heat or liquids.
