I am an industrial chemist, who recently became certified to teach secondary science in Maryland public schools. My goal is to contribute to the training of future scientists in a meaningful way for the duration of my career. I also want to work on my own professional development through interaction with other teachers, scientists and other professionals. I have many interests including reading literature and poetry, museums, art,cycling and tennis. I have a houseful of pets that I enjoy taking care of. I am looking forward to working with the NSTA and its affiliates.

Hi Dorothy, The interactive PPTs must require a subscription now...they were excellent as I remember. The same company has other science resources at : There are PPTs; not sure whether they're interactive. Hope all is well; I had a teaching interview today by ambush LOL. They told me it was a certification meeting, but surprised me ...

Mario, I just found an excellent free NSTA book chapter that you might like to read. It has exhibits, flow charts and tables that attempt to organize and connect the many facets (theories, standards and practice) of the complex field of educational assessment.It's entitled, "A Rational for Assessment". It should read, "A Rationale for Assessment", but the editor must have missed the typo. Never...

Hi All, This morning, I read a very good NSTA book chapter on assessment entitled, " A Rational for Assessment". This actually should be called, "A Rationale for Assessment", and the chapter presented an excellent overview of the field of assessment and its connection to standards and educational theory. There's a helpful teacher checklist and other informative tables and exhibits. It's well wo...

5 Bringing Chemistry Instruction into the 21c
I was very impressed with this resource. It shows how green chemistry can be used to practically cover a wide-range of traditional theoretical chemistry concepts such as: •Rates of reaction •Catalysis •Chemical cycles •Energy •Thermochemistry •Experimental design •Law of Conservation of Matter •Stoichiometry •Percent yield •Solubility •Polarity •Phase change •Organic chemistry •Synthesis The presenters explained three different experiments in detail with pictures of the lab setups which was very helpful. The calorimetry experiment is highly relevant to addressing the challenges that we, as a society, face concerning future energy conservation. I think that students will appreciate learning about relevant concepts such as 'atomic economy' and translating that concept to the processing level at the pilot and manufacturing plants. I think that teaching models based upon green chemistry offer the opportunity to branch out into application, which to my mind is the best w

5 Great Visuals and Linked Resources
Excellent presentation of a fascinating subject. It's amazing how brain scanning and digital imaging has revolutionized medicine. To see the physical changes that take place within the brains of long-term drug users was interesting. I'm very curious to learn what experimental methods they used to detect changes to the chromatin. Are changes found during meiosis? Are the changes passed on to offspring? To what extent, and on which level? The presentation has many informative diagrams of the brain and visuals depicting the mechanisms of neuro-transmission. I would include some of them in a lesson for secondary science students. There are also many linked free resources provided. As a teacher, I'm interested in the impulse-control region of the brain because many of my students have little to no impulse control which disrupts their classroom learning experience.

2 Better Inquiry Resources Available
Why are the authors suggesting to make a model based on kinematics to explain a phenomenon that occurs at reduced gravity? The article has a good rubric for scoring student inquiry methods, but I wouldn't use their methods as a template.
