What’s the Matter?CAST 2011
Meg Young, Lamar High School
George Hague- inspired chemistry teachers across the nation.
Rosendo Garcia- worked hard to make ACT2 a great organization.
Find their story on the ACT2 website. Dr. Diana Mason continues to mentor high
school teachers in Texas.
Find mentors
Mentors/ Professors: Dr. Larry Peck &Robert Beck Clark
Find a teaching partner: Roberta Young
Join ACT2 and STAT Come to the Biennial Conference at Mary Hardin Baylor. June 24-28, 2011
Go to Chem Ed 2013 in Waterloo, Canada 7/28-8/1, 2013
Go to a BCCE 2012 at Penn. State Present at CAST next year.
Attend a Material Science Camp.
Network
Edmodo – Join the DFW group by entering 7zuap0.
Edinformatics- find state tests on chemistry. Since you won’t see any STAAR released items for a few years, use other state test questions. Use VA, MA, and New York.

Learn to make podcasts: speaker Jonathan Bergmann.
Use JING for short podcasts.
Teaching aids
Take Chem 13 News from Waterloo, Canada Excellent high school resource. Take the Journal of Chemical Education. Take Wired to learn about technology.

Worksheets for presentation at
Formulas: H2O, HOH Lewis Dot Diagrams: Ball and stick diagram:
Spacefilled model:
Use water molecule kits.
Help students picture matter.
Use pictures on worksheets Use common objects to model matter such
as nuts and bolts, pop beads, small balls, beans, etc.
Look for POGIL worksheets. POGIL is process oriented guided inquiry lessons. These always include a “model” that leads the student to develop understanding about how matter interacts.
Modeling matter for students
Go to a POGIL workshop Look at POGIL materials online: TED talk on POGIL
http://www.pogil.org/about/straumanis-ted-talk
Rewrite worksheets to model POGIL style. It really makes a difference.
Learn to use paint or a draw program to make pictures or models.
POGIL
To help ESL students, add pictures of the polyatomic ions. Use paint to make pictures.
INIRETT _____________________ ENITTAR _____________________
Scrambled ions
Nuts and bolts can be used to model % composition.
Have students weigh a bolt and 3 nuts to find the % composition of the compound BN3.
Use nuts and bolts to model elements, compounds, and mixtures.
Use Nuts and Bolts
Stoichiometry occurs in everyday life. The Arlington GMC plant makes 4-wheel drive SUVs. There are 1350 SUVs without wheels. There are 2500 wheels available.
Reaction: __ SUV body(s) + __ Wheel(s) __ Wheeled SUV(s)
10. How many finished SUVs can be made?_________ 11. What is the stoichiometric ratio of trucks to
wheels? ___________ 12. Which of the materials is in excess? ___________ 13. How much of the excess material is left over? ____ 14. What limited the amount of product made? ______
Use everyday life examples
Did you know that you can put 2 tablespoons of popcorn in a brown lunch sack and microwave it?
I use an air popper at school. Most students have never seen popcorn pop. Easy to mass before and after to find the % water. It should be between 13-15% water.
% water of popcorn

Use Music to help students.
Students must be able to identify precipitation reactions, acid-base reactions, and redox reactions:
Nitrogen + hydrogen ammonia N2 (g) + H2 (g) NH3(g)
TEKS 10H
Acid-base (Neutralization)
Oxidation-reduction
Precipitation Double displacement
Single displacement Synthesis Decomposition Combustion
Have students move from station to station and record information about chemicals.
Use station labs

Check out ptable or emd pte for IPad Look for animations: http://www.btinternet.com/~chemistry.diagrams/
Hspec_animation2.swf animation that shows why elements have a spectrum http://winter.group.shef.ac.uk/orbitron/ shows the shapes of the orbitals http://jersey.uoregon.edu/vlab/elements/Elements.html shows the absorption and emission spectrum of the
elements. http://intro.chem.okstate.edu/WorkshopFolder/

Chemical heritage magizine Napoleon’s Buttons, The Disappearing
Spoon, The Immortal Life of Henrietta Lacks, Chem 13 News The Science Teacher Journal of Chemical Education
Reading is fundamental.
Check out Elements, Compounds, and Mixtures Worksheet II
He was a master at using paint to make pictures. This is one of the few
electronic copies that I have. I am sharing it to honor his memory. Example of Heterogeneous mixture.
In memory of Cole Hardison
Have a great school year.Come to the DFW meetings. HOPE TO SEE YOU AT MARY HARDIN BAYLOR. Contact me at [email protected] or [email protected]
Have a great CAST
