💼 Same science, someone's shop
The experiment on the left is the business on the right
An electromagnet on your desk is the motor a wiring shop rewinds. The pH strip in your kitchen is the effluent plant an engineer runs. Each pair shares real vocabulary, and each blueprint shows the money as a range, the licences by name and the worst case before the best.

⚖️ The lab rules
Four promises this bench keeps, and four it asks of you
🧑🔬
Safety before spectacle
Anything with flame, current from the wall, or a chemical stronger than vinegar says so up front and asks for an adult. If a step scares you, stop. That is the right call, not a fail.
🏠
Household means household
When a card says nothing to buy, it means the kitchen, the toolbox and the stationery drawer. No experiment here is a shopping list in disguise.
📓
What you saw is the result
Every page tells you what you should see. If yours came out different, write down what happened and why you think so. That is science. Copying the expected answer is not.
💰
Money as a range, never a promise
Every blueprint shows costs as a window with the year attached, names the licence and its official portal, and pins the worst case next to the best. No agent, no fee, no guaranteed income, ever.
