1. Tuesday December 1 st, 2015 Day 1 Tuesday December 1 st, 2015 Day 1 Science Starters Sheet 1. Please have these Items on your desk. AR Book 2- Science Starter: Two vocabulary words- Chromosomes- A self-replicating body present in the cells of higher plants and animals, especially observable during mitosis. Cell Cycle- Starts with the formation, then the growth and development, and finally death. Each cell has their own cycle, and it goes at it’s own pace. Agenda
