What You'll Learn
Peer review is how scientists check each other's work. Before research is published, other experts evaluate the methods, data, and conclusions to ensure they are valid.
Key Words
Tap a word to see its definition.
Materials Needed
- straws
- paper clips
- cups
Safety First
- Have an adult check your set-up before you start, and tidy everything away afterwards.
Steps
Look at the vocabulary words and write a definition for each in your own words.
