High school chemistry teachers in U.S. and U.S. territories can apply for a Hach Professional Development grant to fund up to $1500 of expenses. Applications will be accepted through January 4th. Qualified expenses include registration, travel, tuition, books/resources and substitute teacher pay. Activities must be completed by August 31, 2017.
If your not familiar with the video series "The Mystery of Matter, Search for the Elements" then I highly recommend their use as part of your curriculum. The Mystery of Matter: Search for the Elements is a PBS series about the amazing human story behind the Periodic Table. The videos, most of them 4-12 minutes long, draw on the interviews, re-enactments, animations and photographs that were shot and collected for the PBS series, with supplementary animations and images as needed. In all, the videos make up about three hours of programming. I shared several of the video clips with my high school students and they really seemed to enjoy them mentioning the reason was because the videos were done using actors to tell the stories and it was similar to watching a movie.
In teacher preparation, the Vygotsky based theory of formative assessment is integral because teachers and teacher educators who recognize their knowledge as knowledge in formation are better prepared to recognize the value of students’ knowledge. After all, most learners find it easier to build upon prior knowledge when learning material as opposed to having the material dissociated from prior experience and viewed as a completely new and isolated material.
The ACS Committee on Chemical Safety has published new Guidelines for Chemical Laboratory Safety in Secondary Schools. This document is organized with the R.A.M.P. concept – Recognize the hazard, Assess the risk of the hazard, Minimize the risk of the hazard, and Prepare for emergencies. The online document includes two pages for each letter that could be printed and posted in the classroom to reinforce these principles of safety. The documents are provided to strengthen the safety practices of teachers and help them to promote a culture of safety that their students will take with them throughout their academic and professional careers.
This week I had the opportunity to attend part 2 of a 3 day PD for Gizmos, courtesy of a district grant working with ExploreLearning. In a room full of middle school science colleagues (half of whom I knew), I was able to glean a ton of great information.
AMTA will be hosting a distance learning Chemistry 2 course that will run from January 19th -April 27 (15 weeks), with an open house to prepare with technology on January 12th. It will be led by expert chemistry modeling leaders Larry Dukerich and Brenda Royce.
In July of 2016 we learned the names of the four new elements that were confirmed in January; Nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og). Although the newest superheavy elements complete the seventh period of the Periodic Table, curiosity has been reignited in our classrooms as students ask, what’s next?
“What we Call Misconceptions May be Necessary Stepping Stones Toward Making Sense of the World” is an article identifying how misconceptions can be turned into sense-making exercises and classroom conversations to help students come to meaningful, and eventually “correct” views of scientific concepts.
Most chemistry teachers I know do flame tests with their students. It ties in well with many topics, is colorful and the kids enjoy seeing the colors and burning stuff. There are many applications. For years I always mentioned that astronomers use the idea of the flame test. They simply look at stars and examine the spectra from the light of these stars. They then match the spectra with the elements and then they can see and infer what elements are millions of light years away. I always mentioned this but never was able to demonstrate it.
The American Modeling Teachers Association(link is external) has announced a new webinar series to be hosted by experts in the field. The webinars will include a variety of topics and are free to members. Space is limited to the first twenty-three teachers to sign up, but each session will be recorded and made available to wait-listed teachers. The webinars will be hosted on GoToMeeting.
