The claim, evidence, and reasoning (CER) framework can be used to write a good paragraph.

KerryEmmanuel said in an interview with students that at the end of the day it was just raw curiosity.The desire to explain how the world works drives the questions we ask and the investigations we conduct.

We are planning a unit on matter.We have helped students define matter as something that has mass and takes up space by having them observe liquids.I want to start thinking about air.The students want to know if air is or is not important.Is air matter?

We can ask our students what data they need to answer the question, and how they can collect that data.Students will have to determine if the air has mass or not.They might suggest that they weigh a basketball multiple times as they use a pump to add more air.Students can create an explanation once they conduct an investigation.What does a good explanation look like?

Students might suggest that air is important.The weight of the ball increased when we pumped more air into it.One of the characteristics of matter is weight.
