Students will complete this digital vocabulary glossary (digital VocabuGlossary or DVG) one of two ways. You can assign this for students to fill out at the beginning of the unit to front load vocabulary or you can have students complete the terms that were used in class that specific day for a ticket out system. I personally prefer the quality of the work that comes when students are asked to work on it at the end of each class period. There are 15 terms included and are based off of 8th grade Science TEKS for Texas.
