• Hello to all!

    • Students:  Log on to your Chemistry CANVAS page. You may send me messages in Canvas or use your student account to email me. (You are not bothering me; it is my JOB to answer your school related questions! :-)


    • Parents:  Please have your student sit with you as they log on to his or her Canvas page and click on the chemistry course.  You may contact me through email: cmack1@houstonisd.org.  Be sure to include your name and your student's name.
