This resource turns historical co₂ levels into a complete, ready to use review for Grade 9-12 earth science, covering the same NGSS standard from three different angles.
Students will answer questions such as "What was the CO₂ concentration in the atmosphere around 1750, prior to industrialization?", "Which location is known for providing real-time CO₂ data since the late 1950s?", and "Which gas is primarily responsible for the greenhouse effect related to climate change?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned earth science unit. The unit also covers the Carbon Cycle, Photosynthesis, Oceanic Carbon Sequestration, Fossil Fuels and Carbon, Volcanism and the Geological, and Human Contributions, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard HS-ESS2-6.
