Carbon Sequestration in the Mid-Columbia

February 19, 2009

null

Pete McGrail, PNNL scientist, sent us a copy of his Powerpoint for a Pasco-Kennewick Rotary presentation and some references to other links on the Internet. The following article is based on these resources.

One of the great energy sources of the US is coal. We have vast supplies of the stuff, but there is a problem. When you burn coal to produce heat, generate electricity, or drive machinery, huge amounts of carbon dioxide are produced. Whether one believes that global warming is man made or not, there can be no doubt that dumping megatons of carbon dioxide into the atmosphere cannot be a good thing. A solution is needed if we are to take advantage of our coal reserves in the future.

Science Instruction in Oregon and Washington

April 1, 2002

A RECENT REPORT INDICATES THAT SCIENCE INSTRUCTION IN CALIFORNIA IS WOEFULLY INADEQUATE
null

I am sorry to report that in the dozens of Oregon schools I have visited in the past four years, the actual teaching of science in grades K-5 is not a lot different from that reported in California. Grades K-2 rarely reported any regular science instruction at all. The norm in grades 3-5 was two 1/2-hour sessions per week (alternating with social studies). The nature of the curriculum was almost universally fact-oriented content while instruction was primarily reading from texts.

What’s Worth Knowing, and What Role Can Inquiry Play? (Notes for Wenatchee Keynote)

March 28, 2002

null

To answer the question in the title, we will examine some of the major societal trends and the educational needs created if these trends continue into the future. A brief look at the domains of learning will be followed by a review of what we know about how we learn and some models that seem to be compatible with this view. Of those discussed, we will focus on Science Inquiry as a tool that can be used by science and math teachers to empower their students in their roles as life-long learners.

Scientific Inquiry Performance Task

Brief Overview of Task:

Students will use the property of paper to absorb liquids and to transmit the liquid along a strip at different rates depending on the liquid, the type of paper, and other variables. For young students the teacher will set up the experiments with student activity somewhat limited. For older students the control of the experiments is transferred to the students.

INVENTION!

By
Dr. Bob Valiant

Children are great inventors. They have not developed the inhibitions that restrict many of us from exploring far-out ideas and novel solutions. The trick is to come up with ideas for what to invent and then to organize for possible solutions. Here are some ideas for the teacher and for the students to come up with some exciting new inventions.
