Claim, Evidence & Reasoning

1. Claim, Evidence & Reasoning Ms. Drake 7th grade Science Brookville Intermediate School

2. Claims- Evidence- Reasoning • Claim- • Answer to the question! • Usually a statement • Evidence- • Observations • Facts • Data from experiment • Quotes • Statistics • Facts • Reasoning- • What do your facts/data mean? • How do your observations support your claim? • Use words such as means, tells, shows, and demonstrates.

3. Let’s try one together!

4. What Shape are Cells? Cells can have lots of different shapes. In this lab, the animal cell was like a wavy circle. The plant cell looked like a rectangle. The bacteria was squiggly. Since all these cells had different shapes, I can tell that cells don’t just have one shape.

The bacteria was squiggly (evidence). Since all these cells had different shapes, I can tell that cells don’t just have one shape (reasoning).

6. Let’s try another one together!

7. Do you think the “scar” on the Atlantic Ocean floor is a ridge or trench? The scar is a ridge. The elevation of the scar is higher than the two stations on either side.

9. One more together!

10. Mr. Garcia: Do you think the climate is changing? Make sure you support your idea with evidence and reasoning. Olivia: I think the climate is changing because this fall has been really warm. Mariela: Does being warm just one fall count as evidence for climate change? Nate: No, climate is long term changes. It is just weather if it is one day or a month or a season. So I think it is changing because the air temperature has slowly gotten warmer over a long period of time. The average temperature has increased 2 degrees over the 100 years.

12. Card Activity • Read your cards and decide which of the four groups they go in- • question • claim • evidence • reasoning

13. Claims- Evidence- Reasoning • Claim- • Answer to the question! • Usually a statement • Evidence- • Observations • Facts • Data from experiment • Quotes • Statistics • Facts • Reasoning- • Logic that ties evidence to the claim. • Detailed explanation for why the evidence led you to make the claim. • Deep explanation of the science concepts or scientific principals
