Crafting Scientific Claims with Evidence

The video tutorial introduces the Claim, Evidence, Reasoning (CER) format used in science. It emphasizes the importance of supporting claims with evidence and explains how reasoning ties evidence to claims. The tutorial provides an example using silicon to demonstrate the CER process and concludes with an activity for students to practice the format.

What does the 'C' in CER stand for?

• Claim

• Conclusion

• Content

• Context
