Protect eyes from sunlight
1 · Learn
Sunlight helps us see during the day, but looking directly at the Sun can damage eyes. We must never look at it, including through a lens or binoculars.
A hat and suitable sunglasses can help protect us outdoors when used as adults advise. They do not make staring at the Sun safe. Study shadows or use approved indirect observations instead.
2 · Worked example
I want to learn about the Sun's position. I observe a shadow on the ground with an adult, not the Sun itself.
3 · Your turn
Do sunglasses make it safe to stare at the Sun? What could you observe instead?
Check your answer
No. You could safely observe a shadow on the ground under adult supervision.
4 · Apply your learning
Plan an outdoor observation with an adult, including shade and eye-safety rules. Record a shadow, not a direct view of the Sun.
Adult guidance and safety
Never improvise solar viewing devices or use optical equipment for direct viewing.

My observation notebook
With an adult, look at a safe real example or a checked photograph. Name the example and say which you used. Record what you actually notice. Do not taste plants or materials, approach unknown animals or invent missing observations.
Ask your teacher for support with the method and recording. A prediction is what you think might happen; an observation is what you actually see, hear or feel safely.
