🔬 Science in Everyday Life • Lesson 2/6 ⏱️ Target Time: 12 mins

Passive for Processes & Sequence Words

Discover how natural light behaves in our atmosphere while mastering natural, step-by-step descriptions without unnecessary grammar jargon.

👨‍🏫 For Teachers

• Allocate 12 minutes: 4 minutes for guided rule analysis and 8 minutes for independent student station drills.

• Pair students for Station 4 to compare error fixes before running a rapid whole-class plenary check.

🎒 For Students

• Carefully read through the 4 rules in the blue summary table before starting the exercises.

• Check the bracketed clue (hint) for every question to test your grammar choices.

Lab Rulebook: Scientific Process Rules

Rule Concept	How It Works	Atmospheric Example
1. Present Simple Passive	Use `is / are + past action form` to explain a routine or natural step in nature.	"Sunlight is scattered by the air."
2. by + agent (Who did it?)	Mentioning the actor is optional. Omit it when the doer is obvious, unknown, or not significant.	"Some violet light is absorbed high in the atmosphere."
3. Sequence Words	Use signposts like first, then, next, finally at sentence beginnings to direct the order of events.	"First, sunlight enters the atmosphere."
4. Modal Passives	Combine `can be + past action form` to show what is possible to detect or observe.	"The colours can be seen at sunset."
