• Hello to all!

    • Students:  Log on to your HUB page (Login to The Hub https://houston.itslearning.com/) and click on your Chemistry course.  Then click "Resources."  Send me messages in the HUB 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 HUB 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.
