As a high school or undergraduate Mathematics teacher, you can use this set of computer-based tools to help you in teaching topics such as Differentiation, Derivatives of Polynomials, and Tangent Line Problems in Introductory Calculus.

This lesson plan allows students to perform polynomial differentiation and solve tangent line problems using climate data such as atmospheric CO2 concentrations data since 1950.
Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in Mathematics.

Use this lesson plan to help your students find answers to:

1. Plot a graph and find the polynomial equation to model the average yearly atmospheric CO2 levels from 1950 to 2017 (using data records provided).
2. Compare and analyze the rate of change of atmospheric CO2 levels by applying Polynomial Differentiation.
3. Based on observed trends, what will the atmospheric CO2 level be in 2100?

Reading (30 – 45 min) A reading that introduces the topics of differentiation
and derivatives of polynomials. The resource also includes exercises.
Micro-lecture (video) (~10 min) A micro-lecture (video) that explains polynomial differentiation
with examples and practice questions.
It also includes a tutorial on tangents of polynomials.
Classroom/ Laboratory activity (~60 min) A classroom/laboratory activity to learn and apply polynomial differentiation and solve tangent line problems for global average CO2 data from 1950 to 2017.

Here is a step-by-step guide to using this lesson plan in the classroom/laboratory. We have suggested these steps as a possible plan of action. You may customize the lesson plan according to your preferences and requirements.

1.Introduce the topic through a reading and exercises
2. Play a micro-lecture (video)
3. Conduct a classroom/ laboratory activity
  • • Then, help your students apply the learned concepts through a hands-on classroom/laboratory activity, “Mauna Loa Yearly Average CO2”, by Thomas J. Pfaff at Sustainability Math. This activity uses atmospheric CO2 data from the Mauna Loa site for the period 1950 to 2017.
  • • This activity will help students to
  • •  observe the trend in increasing atmospheric CO2 levels
  • •  infer the approximate year when atmospheric CO2 levels could cause global temperatures to increase by 2°C (leading to serious climate change-related problems)
  • • determine the desired trends in atmospheric CO2 levels that could help in avoiding or mitigating such climate change-related consequences
  • • Download the material in the project, “Mauna Loa Yearly Average CO2”, under Calculus I – Differentiation Related Projects.
  • • Conduct the exercises 1-6 to predict atmospheric CO2 levels in the future. (Optional: exercises 7 and 8).
  • •  Discuss the possible impact of these trends on global temperature and climate.
