Themes By Eris, Coding Tutorial - Part 1: Getting Started Temperate Deciduous Forest The Temperate Deciduous Forest The temperate deciduous forest occupies much of the middle of the Whittaker diagram, and to those of us who live here, it sure feels that way. Rapid changes from cold and dry to wet and warm or to any of the other corners of the climate envelope are often swift and dramatic. A favorite saying among the natives is "if you don't like the weather, wait a minute". As the diagram indicates, the average annual temperature ranges up to about 20 C down to freezing. Southern Ohio has a different feel to it. More on Forests - Forests in Europe Back

Theories of acids and bases In fact, the reaction between HCl and water is reversible, but only to a very minor extent. In order to generalise, consider an acid HA, and think of the reaction as being reversible. Thinking about the forward reaction: The HA is an acid because it is donating a proton (hydrogen ion) to the water. The water is a base because it is accepting a proton from the HA. But there is also a back reaction between the hydroxonium ion and the A- ion: The H3O+ is an acid because it is donating a proton (hydrogen ion) to the A- ion. The reversible reaction contains two acids and two bases. When the acid, HA, loses a proton it forms a base, A-. Members of a conjugate pair differ from each other by the presence or absence of the transferable hydrogen ion. If you are thinking about HA as the acid, then A- is its conjugate base. If you are thinking about A- as the base, then HA is its conjugate acid. The water and the hydroxonium ion are also a conjugate pair. A second example of conjugate pairs

Mountain Ave., Upland, CA 91786 (909)949-0857 Fax (909)949-2968 E-mail: EllenDomb@compuserve.com This paper was first presented at the Invention Machine Users Group Conference, Feb. 3-4, 1997, in New Orleans, LA USA. TRIZ as practiced in the late 1990's is a large, complex system consisting of a wide variety of tools and techniques. Beginners, however, find this richness overwhelming. The people who are looking for TRIZ training are our customers: Engineers & technical managers Product development teams Manufacturing teams Inventors Strategic planners They have 3 very explicit "Customer Requirements" Fast success Minimum classroom time Familiar terminology, cases, examples There is a fourth customer requirement that has been observed frequently, but is never stated directly by the customers. "Show me what's different, and teach me to use it. The roadmap for simplified TRIZ using the Invention Machine Laboratory (tm) (IM) software is shown below.
Terrific Mini Guide to Help Students Think Critically December 26, 2014 Questioning is the key to critical thinking and through questions students get to explore the deep layers of meanings that would otherwise go unnoticed. Of course not all questions have this analytical ability. For instance, closed questions tend to limit the thinking choices available for students. The same with questions that promote factual recalling. Questions that emphasize the mechanical on the analytical are out of the list. In today's post, I am sharing with you this mini guide created by Foundation of Critical Thinking which you can use with your students to help them better comprehend and apply critical thinking in their learning. I learned about this great resource from a post shared by Education to Save The World. Image credit: Foundation of Critical Thinking
