Technical Details

### Teaching Tips

- Educator has to be careful to not allow students to draw too broad of conclusions from one station. For example, a given station may indicate a cooling trend even though the globe as a whole is warming.
- Students unfamiliar with Excel should complete an introductory Excel activity (see resources listed in activity) before working through this activity.
- Students should be able to work through this activity at home or in a computer lab with no supervision.

### About the Science

- Students work with real data for their home region.
- Data used in the activity is only available until 1994, which is acceptable given the activity is about historic data, but certainly not ideal. More recent data is available on the USHCN Website so the educator can update the activity.

### About the Pedagogy

- Activity is primarily a mathematical skill builder, using data from a scientific database.
- Questions posed in the instructions at various points in the activity help keep students on track and help them to abstract from the presented data and see the reason for the statistical analysis.
- Activity relies heavily on Excel knowledge and skills - could be a disadvantage for some less tech-savy students.

**This resource engages students in using scientific data.**

### High School

#### Performance Expectations: 1

HS-ESS3-5: Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change and associated future impacts to Earth systems.

#### Disciplinary Core Ideas: 2

HS-ESS2.D1:The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.

HS-ESS2.D4:Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere.

#### Cross Cutting Concepts: 9

HS-C1.2:Classifications or explanations used at one scale may fail or need revision when information from smaller or larger scales is introduced; thus requiring improved investigations and experiments.

HS-C1.4: Mathematical representations are needed to identify some patterns.

HS-C2.1:Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.

HS-C2.2:Cause and effect relationships can be suggested and predicted for complex natural and human designed systems by examining what is known about smaller scale mechanisms within the system.

HS-C3.1:The significance of a phenomenon is dependent on the scale, proportion, and quantity at which it occurs.

HS-C3.3:Patterns observable at one scale may not be observable or exist at other scales.

HS-C3.5:Algebraic thinking is used to examine scientific data and predict the effect of a change in one variable on another (e.g., linear growth vs. exponential growth).

HS-C4.4:Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models.

HS-C7.2:Change and rates of change can be quantified and modeled over very short or very long periods of time. Some system changes are irreversible.

#### Science and Engineering Practices: 9

HS-P1.3:ask questions to determine relationships, including quantitative relationships, between independent and dependent variables

HS-P2.6:Develop and/or use a model (including mathematical and computational) to generate data to support explanations, predict phenomena, analyze systems, and/or solve problems.

HS-P3.4:Select appropriate tools to collect, record, analyze, and evaluate data.

HS-P3.5:Make directional hypotheses that specify what happens to a dependent variable when an independent variable is manipulated.

HS-P4.1: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-P4.2:Apply concepts of statistics and probability (including determining function fits to data, slope, intercept, and correlation coefficient for linear fits) to scientific and engineering questions and problems, using digital tools when feasible.

HS-P5.2:Use mathematical, computational, and/or algorithmic representations of phenomena or design solutions to describe and/or support claims and/or explanations.

HS-P6.1:Make a quantitative and/or qualitative claim regarding the relationship between dependent and independent variables.

HS-P7.4:Construct, use, and/or present an oral and written argument or counter-arguments based on data and evidence.
