Students make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix the calcium carbonate with oil. Finally, record and analyze their observations. Full Review »

Students identify and interpret the Scientific Method and that it can be applied to solving everyday problems. They also test for the the presence of carbon dioxide in exhaled air by blowing through a straw into a solution of calcium hydroxide. Finally, students generate hypotheses to explain the divergent results. Full Review »

Students explore the role of dinosaurs in the carbon cycle. They discuss how dinosaurs obtained carbon for their bodies and how organisms living in the ocean use carbon dioxide to make calcium carbonate shells. Students observe a demonstration of chalk releasing carbon dioxide and explain the chemical reaction that occurs. They diagram and write an essay describing the carbon pathways. Full Review »
