# Global Atmospheric CO2 Concentration (800,000 Year Timeline)

|

Synopsis
• This resource displays global atmospheric carbon dioxide concentration data in the form of an interactive chart and a table.
Teaching Tips

Positives

• This interactive resource provides two different ways for students to explore data (chart and table).
• The site explains how the data was collected.

• There are multiple layers of data to explore and navigate. Teachers should familiarize themselves with the various capabilities of the interactive. For instance, selecting the "play" arrow will move through the chart/table to show how the data has changed over time.
• Because the interactive provides so many options for viewing the data, students may need clear instructions as to which dataset to explore.

Differentiation

• As part of a science history lesson, this interactive could be used to explore the technological advancements that may have led to changes in COin the atmosphere.
• This interactive also lends itself to exploring ratios and percentages, so it could be used during math lessons.

Scientist Notes

Datasets used contain estimates of the global atmospheric concentration of CO2 from ice core samples (Dome C core). This resource is recommended for teaching students long-term trends of global CO2 concentration in the atmosphere.

Standards
• Next Generation Science Standards (NGSS)
• ESS3: Earth and Human Activity
• MS-ESS3-4 Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.
• MS-ESS3-5 Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.
• Common Core Math Standards (CCSS.MATH)
• Expressions & Equations (6-8)
• CCSS.MATH.CONTENT.8.EE.B.5 Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
