Today’s story

Share What You Found

Dani measured her plants. Eli measured his. The numbers do not match. They start to argue.

Then Dani says, Show me how you measured. Eli says, Show me yours. They put the tables side by side.

Scientists share like that. They explain with evidence and they listen. The steps show how.

    Same every time

    Three rules

    Rule 1Back your idea with evidence.

    Data is stronger than a guess.

    Rule 2Listen before you answer.

    You may learn something.

    Rule 3Disagree with the idea, not the person.

    Kind words keep people working together.
