Final test: science experiments and STEM — Science experiments for kids

What you do

Find the experiment, use the idea — “decide which experiment a question is about, then use its science”

1. 1. Read the question and find its experiment.
2. 2. Use that experiment’s science idea.
3. 3. For a fair test: one thing changed, the rest kept the same, one thing measured.
4. 4. For safety: an adult helps, nothing goes in the mouth, no heat, sharp tools or plug points for children.

Use it for: Final revision before a science olympiad, science fair or school exam.

Worked example: 🛟 Which rule keeps you safe when working with sunlight? → never look at the Sun
