Scientific information can help people make decisions about health, technology, energy and the environment. Good decisions consider evidence, uncertainty, benefits, risks and different viewpoints. A scientific answer is not always the only factor in a community decision.
Example
Choosing how to reduce household waste involves evidence about materials, local recycling systems, cost and convenience.
Key terms
Risk:
The chance that something harmful may happen.
Benefit:
A positive outcome or advantage.
Evidence-based decision:
A decision informed by reliable information.
Questions
1. This week, the key science idea is:
how evidence informs everyday science decisions
memorising a definition without using evidence
choosing an answer before looking at observations
ignoring the conditions that affect a result
2. Which key term means “The chance that something harmful may happen.”?
Risk
Benefit
Evidence-based decision
Variable
3. Which key term means “A positive outcome or advantage.”?
Benefit
Risk
Evidence-based decision
Prediction
4. Which key term means “A decision informed by reliable information.”?
Evidence-based decision
Risk
Benefit
Conclusion
5. Which action best helps a student learn about science decisions in everyday life?
weigh evidence, benefits and risks for one local environmental choice
Copy an answer without checking it
Skip the observations
Use only a guess
6. Why is evidence important when studying science decisions in everyday life?
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 evidence informs everyday science decisions?
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 science decisions in everyday life. 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 science decisions in everyday life?
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 science decisions in everyday life rather than just repeating words?
weigh evidence, benefits and risks for one local environmental choice
Reciting the title only
Choosing the longest answer
Skipping the task
13. How can the key terms help when discussing science decisions in everyday life?
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 science decisions in everyday life 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 science decisions in everyday life?
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 science decisions in everyday life?
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 science decisions in everyday life?
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 science decisions in everyday life 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 evidence informs everyday science decisions
memorise unrelated facts
avoid asking questions
choose answers at random
