Measuring Things

Scientists do not guess — they measure. Length uses rulers and meters. Mass uses scales and grams. Time uses stopwatches and seconds. Temperature uses thermometers and Celsius. Pick one: measure something in your house right now and write down what you found with its unit.

I measured [object].
Result: [number] [unit].
Tool used: [ruler, scale, stopwatch, or thermometer].
02

Reading Data

Data is just organized observations. Look at this temperature record, then write one sentence about the trend you notice and what you would predict for Day 6.

Day 1: 14°C · Day 2: 17°C · Day 3: 15°C · Day 4: 19°C · Day 5: 22°C
Trend: [your sentence].
Day 6 prediction: [your prediction].

Your Lab Setup

Real scientists set up their workspace before they start. List 5 items you would want in your personal invention lab — tools, materials, or equipment. Explain what each one is for.

1. [item] — [what it is for]
2. [item] — [what it is for]
3. [item] — [what it is for]
4. [item] — [what it is for]
5. [item] — [what it is for]

Complete all three steps first.
