• the difference between observation and unsubstantiated inferences and conclusions
• potential bias

3. Understand how new data and observations can result in new scientific knowledge.

4. Critically analyze an accepted explanation by reviewing current scientific knowledge.

5. Examine investigations of current interest in science (e.g., superconductivity, molecular machines, age of the universe).

6. Examine the scientific processes and logic used in investigations of past events (e.g., using data from crime scenes, fossils), investigations that can be planned in advance but are only done once (e.g., expensive or time-consuming experiments such as medical clinical trials), and investigations of phenomena that can be repeated easily and frequently.

Use mathematical concepts, principles, and expressions to analyze data, develop models, understand patterns and relationships, evaluate findings, and draw conclusions.

1. Create multiple displays of data to analyze and explain the relationships in scientific investigations.

2. Use mathematical models to describe, explain, and predict natural phenomena.

3. Use technologies to quantify relationships in scientific hypotheses (e.g., calculators, computer spreadsheets and databases, graphing software, simulations, modeling).

4. Identify and apply measurement techniques and consider possible effects of measurement errors.

5. Use mathematics to express and establish scientific relationships (e.g., scientific notation, vectors, dimensional analysis).
