How Peer Review Works

🧪Lab Brief #2

Scientific Argument.

🎯 Your mission

Predict it first. Then prove yourself right (or wrong).

⚡ The twist

Nature loves to surprise the careful watcher.

🤯

Mind = Blown

🔬 The more you look, the more nature shows you.

🔮

Make a hypothesis first

Before you start: write down what you think will happen, and why.

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

Step 1 — Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 — Do

Build a working anemometer using paper cups and straws. Calibrate it by counting rotations in a known wind speed.

Step 3 — Observe

Note any unexpected results and think about why they happened.

Step 4 — Record

Share your findings with the class or a partner and discuss what you learned.
