 In an inquiry classroom, teachers facilitate the construction of new knowledge by activating and then pursuing the inquisitive nature of each learner. (Golden Apple Foundation, 2003) It is recommended that students explore the concepts through interactions with the hands-on activities prior to using the powerpoint presentations.  Powerpoint presentations have been created for the convenience of the teacher and are intended for use as a supplement to the hands-on activities. Teachers may modify and adapt them as they choose to meet the needs of their students. NOTE to the Teacher

Carbon Journey ELF Activity: Energy 1C

Carbon as a gas compound: carbon dioxide, CO 2. Image: Image: Carbon as an element in a solid compound: coal. Image: Carbon as an element in a solid compound. This is the mineral calcium carbonate, or limestone, CaCO 3. Carbon in Compounds

Here you see the larger reservoirs: atmosphere, oceans, fossil fuels, the land, and the biosphere. TERRESTRIAL BIOSPHERE OCEANS FOSSIL FUELS ATMOSPHERE Image: The Carbon Cycle The movement of carbon through Earth’s systems is influenced by many geological, biological and physical processes.

Carbon Sinks and Reservoirs Images: Photosynthesis is a process where plants remove carbon dioxide from the atmosphere and using the energy from the sun, create sugars, proteins and other solid carbon-based compounds within the structure of the plants.

Carbon Sinks and Reservoirs Shells formed by marine animals remove carbon from the atmosphere and the ocean.

Carbon Sinks and Reservoirs Images: Some of the single-celled organisms which absorb dissolved carbon dioxide from the oceans Satellite image showing chlorophyll blooms in the oceans. These blooms indicate large amounts of single-celled organisms undergoing photosynthesis.

Carbon Sinks and Reservoirs Sediments being formed at the bottom of the ocean--these sediments play an important role in long term carbon storage. Sediment cores from the ocean floor showing another‘sink’ where carbon is stored.

Carbon Sources Volcanoes release large amounts of carbon dioxide and other gases into the atmosphere. Fires take solid carbon stored in trees and shrubs and return it to the atmosphere in the form of carbon dioxide. The burning of fossil fuels to produce heat and electricity return large amounts of carbon dioxide into the atmosphere.

Carbon Sources Another process that moves carbon dioxide from the soil to the atmosphere is the decomposition of organic material, such as wood or peat by bacteria and fungi.

The carbon cycle has been going on throughout the history of the Earth.
