This is a STEM-based lesson that can be taught in class or online. Students will analyze Weddell seal pup growth data, collected by the Growing Up on Ice, B-030, research team. To use this lesson virtually, include the data cards and have students either construct graphs and upload an image of their graph, or construct a graph and share using the technology that is used online in the classroom.
This lesson is Algebra 1 based. Students will apply skills to:
- Analyze data
- Represent and solve equations graphically
- Draw a line of best fit
- Write equations based on data
- Construct a graph including title, labeling axis, plotting data
- Provide students with PDF of Weddell seal pups data cards (in Lesson Materials) for each group.
- Print copies of worksheets for class (if virtual omit graphing section or use web application.
- Color pencils/markers, rulers, calculators may be useful. If using for stats class or computer apps class modify Excel file, it contains answers.
- Students should be divided into groups of four (though activity can be modified to work in smaller groups or alone).
- Provide each student with a worksheet, questions 1-7 are answered without Weddell seal pup data cards. The data cards include the data to construct graphs.
- Microsoft Excel: Students can use data to construct graphs in Excel.
- Students can insert trend lines and calculate slope and y-intercept and interpret what each means. Slope being growth rate and y-intercept, being predicted size at birth.
- Statistics students can evaluate if these equations are “acceptable” and support their claim with evidence.
Data can be used to build models of Weddell seal pups growing.
- Additional information about Weddell seals along with maps where data were collected can be found at https://icyseals.com/education
- Lesson Materials include data, graphs, trendlines, and R2 values.
Student worksheets including graph construction will be assessed.
