# Human Energy Systems | Activity 1.3

### Target Student Performance

Students use data on Arctic sea ice to construct graphs showing patterns in changing coverage over time.

### Resources You Provide

- pencil (1 per student)

### Resources Provided

- 1.3 Graphing Arctic Sea Ice PPT
- 1.3 Graphing Arctic Sea Ice Worksheet
- 1.3 Grading the Graphing Arctic Sea Ice Worksheet
- Website to retrieve data: http://nsidc.org/data/seaice_index/archives/image_select

### Setup

Print one copy of the 1.3 Graphing Arctic Sea Ice Worksheet for each student. Prepare a computer and projector to display the PPT. If you plan on having students retrieve data themselves, prepare a computer with an Internet connection for each student or pair of students.

### Assessment

Look at students’ arctic sea ice graphs before the next activity. Note the axis titles chosen by the students and use this to gauge how well they understand the information in the graph. Use the 1.3 Grading the Graphing Arctic Sea Ice Worksheet for a model version of the graph. If students had trouble constructing the graph you may need to revisit this activity before moving on.

### Tips

Have students practice inputting one data point into the graph as a group and let them ask clarifying questions before completing the entire graph.
