Physics AP C_UNIT #1

Grade 11/12- APC Physics
Title of the Unit of Study:
UNIT #1: Introduction to Physics
21st Century Theme: Making measurements, creating and interpreting graphs
CCSS Science and Technical Standards Reading:
Cite specific textual evidence to support analysis of science and technical texts, attending
to important distinctions the author makes and to any gaps or inconsistencies in the account. (HS-PS21),(HS-PS2-6)
CCSS Science and Technical Standards Writing:
WHST.11-12.2 Write informative/explanatory texts, including the narration of historical events,
scientific procedures/ experiments, or technical processes. (HS-PS2-6)
WHST.11-12.7 Conduct short as well as more sustained research projects to answer a question
(including a self-generated question) or solve a problem; narrow or broaden the inquiry when
appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject
under investigation. (HS-PS2-3),(HS-PS2-5)
NGSS/Content Standards:
Planning and Carrying Out Investigations
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 (e.g., number of trials, cost,
risk, time), and refine the design accordingly. (HS-PS2-5)
Analyzing and Interpreting Data
Analyzing data in 9–12 builds on K–8 and progresses to introducing more detailed statistical analysis, the
comparison of data sets for consistency, and the use of models to generate and analyze data.
Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to
make valid and reliable scientific claims or determine an optimal design solution. (HS-PS2-1)
Concepts and Skills:
1. Measurements are limited by the precision of the instruments used to make the measurements
2. Graphing dependent vs independent variables to represent relationships between measured data
3. Interpreting a graph and extract key information such as the slope and y intercept
4. How to draw conclusion based on experimental evidence with appropriate level of confidence
5. How to write a lab report
Essential Question(s):
1. What is experimental precision and how does it affect experimental measurements?
2. How do I create a graph to represent the relationship between experimental data?
3. What conclusion can I draw from a graph of experimental data?
4. How does experimental errors affect my conclusion?
Higher Order Thinking Questions:
1. How do errors in each measured parameter combine to affect the precision of the final answer
2. How can you draw a best fit straight line if not all the points fall on that line?
3. How can you claim the data is linear if some points do not fit on the line?
Learning Outcomes/Content Objectives:
Students will be able to:
1. Design experiments to make relevant measurements to measure density
2. Make measurements and correctly use significant figures to represent the precision of the
3. Plot the dependent and independent variables on an X/Y graph and draw a best fit line for the data
4. Use Excel to model the data and calculate the slope of the best fit line
5. Draw a conclusion based on the shape of the data on the graph
6. Write a lab report to summarize the experiment and its conclusion
