- slowing research
- letting us observe things we could not before
letting us observe things we could not before
Hint: Microscopes and telescopes are examples.
Question 2

Question 3
Can scientists use data from other sources?
- yes, such as research others have published
- no, never
- only from television
yes, such as research others have published
Hint: Science builds on shared knowledge.
Question 4
The results do not match your hypothesis. This is…
- a failure
- useful, since you learned something
- cheating
useful, since you learned something
Hint: Refuted ideas still teach.
Question 5
Which is an observation?
