Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=599&id=599 Abstract:This case explores two-species interactions, especially mutualism, and presents students with a problem, namely, the inconsistent treatment of the concept of mutualism and symbiosis in many textbooks. It begins with a question that students will probably not feel qualified to answer: Is the equation of mutualism and symbiosis in a textbook correct? It then guides students through...

Document: http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=272&id=272 Abstract: This case is an exploration of the process of natural selection using white clover (Trifolium repens) as an example. In general, two forms of white clover can be found around the world in various habitats. One type is able to produce cyanide in its leaves, while the other is not. This variation within the clover species,...

Document: Valence Graphic Organizer Abstract: Number of valence electrons for the atoms of this group

Document: Draw an Atom Learning Task (1)   Abstract This task was begun in the Unit, Finding Order; in this unit, this task is repeated after instruction on the wave-mechanics model of the atom.  

Document:ElementRoundtable   Abstract: Element Silent Roundtable Task-This task is an example of an activating, team-building strategy. Each student will write with a different color marker. When instructed to start, one member of the group will write the name of an element on the board, then pass it to the right. Each member of the group will add one element...

Document: Chemistry Unit 2 – Finding Patterns Abstract: This unit, Finding Patterns, takes an inquiry approach to understanding the patterns of properties that exist among the elements. These patterns in properties are then linked to the wave-mechanics concept of atomic structure and the quantum atom. Beginning with isotopes and average atomic mass, as a way of understanding the importance of the...

Document: Science Unit 3 (Revised)-1 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 review...
