    My teaching goal is to help students figure out that science is achievable for everyone and at the same time creating a challenging classroom to help students reach for their own stars and hopefully, to Mars and beyond. Students sometimes need a little inspiration to find that "thing" they  excel at and overcome the weaknesses that hinder them from being successful.

  • I want to thank the community, TBISD, staff, and students for a great and exciting last 14 years out of 27 , but it is time to move onward to the next stage of life called retirement. My goal is to retire to my 15 acreas near Canon City, Co, but for now I will be around the area still. I will try and make it to some of the games and school events.  Remember to keep reaching for the stars and beyond. " You can do it"- waterboy

  • Chemistry---JANUARY 6, 2021 WEDNESDAY

    UNIT 5: CHEMICAL FORMULA AND NAMING- also includes empirial formula and intro to molar mass. Chap 6 Holt textbook- also some redox intro ( chap 19 sect 1 Holt)

    UNIT 6: CHEMICAL REACTIONS- chapter 7 Holt- includes 4 main types of chemical reactions- balacing equations- more on redox reactions-  this is where we pick up some interesting labs/stations/demo

    UNIT 7: THE GREAT STOICHIOMETRY UNIT- NEED THAT CALCULATOR EVERY DAY- will be using dimensional analysis to calculate Avagradro's number, grams, liters etc.  This is the heavy math part of chemistry- you must stay on your toes and practice the problems to be successful.

    UNIT 8: STOICHIOMETRY WITH THE GAS LAWS- will be discovering Pascal, Charles, Boyles, Gay-Lussac gas laws and continue using stoichiometry rules.


    UNIT 10: THERMODYNAMICS INVOLVING CHEMISTRY- specific heat capacity-
