Unit 2 Assessment Unit 2 Performance Expectations & Science and Engineering Practices (SEP) 1. Lab Equipment- Identify common laboratory equipment, and describe and demonstrate their proper use. 2. Measurement- Make measurements using correct significant figures and units, identify significant digits in a measurement, and apply accuracy and precision. 3. Scientific Notation- Convert between standard and scientific notation, 4. SEP3: Planning and carrying out investigations (Grades 6-8) *Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim. *Conduct an investigation and/or evaluate and/or revise the experimental design to produce data to serve as the basis for evidence that meet the goals of the investigation. SEP3: Planning and carrying out investigations (Grades 9-12) *Plan an investigation or test a design individually and collaboratively to produce data to serve as the for evidence as part of building and revising models, supporting explanations of phenomena, or testing solutions to problems. Consider possible confounding variables or effects and evaluate the investigation’s design to ensure variables are controlled. *Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data, and refine the design accordingly. *Select appropriate tools to collect, record, analyze, and evaluate data. *Make directional hypotheses that specify what happens to a dependent variable when an independent variable is manipulated. 5. SEP4: Analyzing and interpreting data (Grades 6-8) *Use graphical displays of large data sets to identify temporal and spatial relationships. *Distinguish between causal and correlational relationships in data. *Analyze and interpret data to provide evidence for phenomena. SEP4: Analyzing and interpreting data (Grades 9-12) *Consider limitations of data analysis when analyzing and interpreting data. *Compare and contrast various types of data sets to examine consistency of measurements and observations.
