Light travels in straight lines. A shadow forms when an object blocks light, and reflection happens when light bounces from a surface. Smooth, shiny surfaces produce clearer reflections than rough surfaces because their reflected light is more orderly.
Example
An opaque ball placed between a torch and a wall makes a shadow because it blocks the light.
Key terms
Reflection:
Light bouncing from a surface.
Shadow:
A dark area where light is blocked.
Opaque:
Not allowing light to pass through.
Questions
1. This week, the key science idea is:
how light produces shadows and reflections
memorising a definition without using evidence
choosing an answer before looking at observations
ignoring the conditions that affect a result

Shadow
Opaque
Variable

Shadow
Reflection
Opaque
Prediction
4. Which key term means “Not allowing light to pass through.”?

Conclusion
5. Which action best helps a student learn about light, shadows and reflection?
test how changing a torch position changes the size of a shadow
Copy an answer without checking it
Skip the observations
Use only a guess
6. Why is evidence important when studying light, shadows and reflection?
It helps us explain what is happening and check our ideas
It means we never need to observe carefully
It replaces all questions with guesses
It only matters after a test is finished
7. Which statement best connects to how light produces shadows and reflections?
It is a useful focus for this science investigation.
It has nothing to do with science learning.
It means evidence is unnecessary.
It can only be studied in a laboratory.
8. A student records observations carefully while exploring light, shadows and reflection. What are they building?
Evidence they can use to explain a pattern
A reason to ignore the results
A way to avoid checking their method
A random conclusion
9. Which is the best scientific habit for light, shadows and reflection?
Notice details, record evidence and explain your reasoning
Change several things at once and guess
Use only the first result you see
Avoid comparing observations
10. If two observations appear different, what should a scientist do first?
Look for evidence and check what conditions were different
Choose the result they prefer
Delete both observations
Assume one must be wrong without checking
11. What makes the example in this lesson useful?
It links a real situation to the science idea
It avoids using any evidence
It proves every situation is identical
It replaces the need for careful thinking
12. Which response shows a student applying light, shadows and reflection rather than just repeating words?
test how changing a torch position changes the size of a shadow
Reciting the title only
Choosing the longest answer
Skipping the task
13. How can the key terms help when discussing light, shadows and reflection?
They make explanations clearer and more precise
They make observations unnecessary
They remove the need for examples
They are only useful in a spelling test
14. A claim about light, shadows and reflection should be strongest when it is:
Supported by observations or measurements
Based only on a guess
Copied without understanding
Unrelated to the investigation
15. Which is the fairest way to improve an investigation of light, shadows and reflection?
Keep a clear method and check results carefully
Change the question halfway through
Choose results before testing
Leave out inconvenient evidence
16. Why might another scientist repeat work about light, shadows and reflection?
To see whether the evidence and pattern hold up
To make the original evidence disappear
Because one result is always enough
To avoid recording data
17. A student has evidence that does not match their first idea. What is the best response?
Revise the explanation to fit the evidence
Ignore the evidence
Change the result to match the idea
Stop the investigation immediately
18. Which conclusion is most responsible after studying light, shadows and reflection?
A conclusion that explains what the evidence supports and notes limits
A conclusion that claims more than the evidence shows
A conclusion with no evidence
A conclusion based on a favourite answer
19. How does light, shadows and reflection connect to real life?
It can help people make observations and evidence-based choices
It has no possible application beyond a quiz
It means everyday evidence is never useful
It can only be discussed by experts
20. What is the best next step after completing this week’s investigation?
Explain what you found using the key terms and evidence
Forget the observations immediately
Assume every result will be the same
Avoid reflecting on the task
21. The most important outcome of this topic is to:
use evidence to understand how light produces shadows and reflections
memorise unrelated facts
avoid asking questions
choose answers at random
