Work with your partner to record in your science notebook exactly what you did to save Fred. You may wish to draw a picture or a diagram to explain your procedure.

There are many ways to solve problems!

What if you were studying human beings in order to solve a problem?

• What kinds of experiments are possible when you study human beings?

• How can you collect evidence in these situations?

What Causes Pellagra?

• Turn topage A-8in your textbook

• Notice – – Challenge– Computer icon

Scientific Analysis is different than other types of writing.

It is important that certain elements be addressed in your analysis.

Analysis of Evidence

Target

What is the key word in this evaluation?

Notice the ‘target’ arrow.

Recognizing Relevant EvidenceWhat to look for:States correct and relevant evidence (such as facts, data and observations).

4

Response accomplishes level 3, AND goes beyond in some significant way, e.g. questioning or justifying the source, validity, and /or quantity of the evidence

3Identifies key evidence with the appropriate number of facts, data, and observations

2Missing key evidence OR insufficient number of facts, data, and observations

1Missing key evidence AND insufficient number of facts, data, and observations; OR states opinion as facts.

0 Missing; illegible, or offers no evidence.

Analysis Questions

In groups of 4, write a response to the analysis questions on page A9/A10Table 1 – question 1Table 2 – question 2Table 3 – question 3Table 4 and 5 – question 4

Target

What is the key word in this evaluation?

What is a ‘trade off’?

A trade off is somethinggiven up in choosing onething over the other

Using Evidence to Make Trade- OffsWhat to look for:Response uses evidence to compare multiple options (what is gained and what is given up – pros/cons) in order to make a choice

4

Accomplishes level 3 AND goes beyond in some significant way. For example, suggesting additional evidence that would influence choices or questioning the validity or quantity of evidence and explaining how it influences choice.

3

Uses relevant and accurate evidence to compare multiple options, and makes a choice based on the comparison.

2

Compares options using evidence BUT reasons or choices are incomplete and/or part of the evidence is missing; OR only one complete and accurate perspective has been provided.

1States at least one option BUT only provides opinions and/or uses inaccurate or irrelevant evidence.

0

Missing, illegible, or completely lacks reasons and evidence.

Tonight’s Homework

• Using the guidelines from the Trade Off rubric, answer:
