Se presentará a los estudiantes un relato histórico del cambio climático global y las acciones humanas que pueden haber afectado esos cambios. El fuego ha sido utilizado por los seres humanos a lo largo de la historia para modificar su entorno, en particular los bosques, en beneficio de los seres humanos. Con el tiempo, el manejo de los bosques ha cambiado y el resultado es un aumento de incendios forestales catastrófico. Este caso explora el uso del fuego como una herramienta de manejo forestal para mejorar la salud de los bosques, disminuyendo así la incidencia de incendios catastróficos y el papel que juega el fuego en el cambio climático.

Patterns Biology is the culminating course in the 3-year high school Patterns Science sequence. Patterns Biology focuses on three-dimensional (3D) learning through culturally responsive, phenomena-based storylines that intertwine the disciplinary core ideas of biology with the scientific and engineering practices and crosscutting concepts as described in the Next Generation Science Standards (NGSS).

The Patterns High School Science Sequence (https://hsscience4all.org/) is a three year course pathway and curriculum aligned to the Next Generation Science Standards (NGSS).

Each course utilizes:
- Common instructional strategies
- Real world phenomena
- Design challenges to engage students and support their learning.

The curriculum is a combination of teacher-generated and curated open-content materials. The Teacher-generated materials are shared freely under a Attribution-NonCommercial-Sharealike Creative Commons License.

This short activity provides a way to improve understanding of a frequently-published diagram of global carbon pools and fluxes. Students create a scaled 3-D visual of carbon reservoirs and the movement of carbon between reservoirs.

This series of activities is designed to introduce students to the role of sediments and sedimentary rocks in the global carbon cycle. Students learn how stable carbon isotopes can be used to reconstruct ancient sedimentary environments. Students will make some simple calculations, formulate hypotheses, and think about the implications of their results. The activity includes an optional demonstration of the density separation of a sediment sample into a light, organic fraction and a heavier, mineral fraction.

Students use information from Project Drawdown to learn about the sectors where climate solutions are being implemented to help slow down climate warming. Students construct a plan for using specific solutions to reduce and remove the amount of carbon dioxide in the atmosphere, and make a claim describing how their plan could work to keep global temperature change below 1.5 ÂC.

This activity describes the flow of carbon in the environment and focuses on how much carbon is stored in trees. It goes on to have students analyze data and make calculations about the amount of carbon stored in a set of trees at three sites in a wooded area that were to be cut down to build a college dormitory.

Students will compare the basis of the derivatives for different plastics in order to determine their expected carbon-14 content. They will then compare ratios of carbon-14 to carbon-12 in plastic samples and categorize the sample according to its percent bio-based composition. Teacher Background Information: This lesson is more of a context design to be used with an existing nuclear chemistry lesson plan. The goal is for students to see the applicability of nuclear chemistry beyond carbon-dating by showing how carbon-dating can be used to determine the carbon sources of products.  Students will need a basic understanding of the carbon cycle, and nuclear equations. The lesson will need students to learn about half-lives halfway through the lesson and that is left open to teach as you wish. There is room for extension to mass spectrometry if you want to incorporate it here for AP Chemistry or as an honors extension. I would suggest using the Flinn POGIL on Mass Spectrometry.   

This is a jigsaw activity in which students are assigned to research one step out of five in the geochemical process stages of the organic carbon cycle. Students then teach their step in cross-step groups until everyone understands all five process stages.

Students explore the increase in atmospheric carbon dioxide over the past 40 years with an interactive online model. They use the model and observations to estimate present emission rates and emission growth rates. The model is then used to estimate future levels of carbon dioxide using different future emission scenarios. These different scenarios are then linked by students to climate model predictions also used by the Intergovernmental Panel on Climate Change.

This is a series of 5 guided-inquiry activities that examine data and models that climate scientists use to attempt to answer the question of Earth's future climate.

Tom Barclay and Hannah Wakeford will talk about what we have learned so far in our exploration of exoplanets to look for biomarkers, signs of alien life.

Students explore the carbon cycle and the relationship between atmospheric carbon dioxide concentrations and temperature. Students create and compare graphs of carbon dioxide and temperature data from one local (Mauna Loa, Hawaii) meteorological station and one NASA global data set. These graphs, as well as a global vegetation map and an atmospheric wind circulation patterns diagram, are used as evidence to support the scientific claims they develop through their analysis and interpretation.
