Document: Unit 3 Section 2 Energy Abstract: This unit introduces students to the topic of energy and the ideas of energy conservation. The students begin by developing understandings about the different forms of energy (i.e. Kinetic and Potential). Students then connect these concepts to develop an understanding about the law of conservation of energy. Furthermore, the unit provides the students...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=304&id=304 Abstract: What is a googol?  Invented by Edward Kasner, an American mathematician who popularized the number in his 1940 book, Mathematics and the Imagination, it is a 1 followed by a hundred zeros. This directed case in estimation and very large numbers was written for a college-level introductory astronomy course, although it could also be used in a variety of...

Document: Science Unit 3 (Revised)-3 Abstract: Unit three is Exploring Change, specifically bonds, energy, and reactions.  The change to be investigated will include indicators of chemical reactions as they relate to chemical bonding and energy changes. Chapters 7 and 8 cover ionic and covalent bonding respectively, while chapters 9 and 19 are the introduction to stoichiometry, chemical reactions. Again, a...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=466&id=466 Abstract: In this dilemma case, the central character, a museum curator, must decide whether or not to show a painting as a hitherto “undiscovered” Cezanne. The stylistic analysis suggests it is for real, but data obtained using different spectroscopic techniques are inconclusive. Students study the data and then make a decision as to whether they believe the painting is...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=243&id=243 Abstract: Does an ice cube melt more quickly in salt water or in freshwater? The answer surprises the group of student science teachers portrayed in this case study. To explain the phenomenon they must figure out the interactions between two clusters of concepts: (1) density and its relationship to floating or sinking, and (2) three modes of heat...
