Why??Why??First year teaching chemistry!!!
I use Technology!!!!
Wrong place at the wrong time!!!

“ChemDiscovery is a full-year high school chemistry
curriculum that integrates computer programs, activities and text to provide an inquiry-
based learning environment design to adapt to individual learning needs
and learning styles.”
