1. If you have late homework, please show me.
WELCOME, BIO-NINJAS
Today you will need: Writing Utensil, Bellwork Sheet, Journal.
If you have late homework, please show me.
Bellwork: Quick Write. At least 35 words.
Summarize what you have learned this week in Biology.
When you finish. Open your Journal and set up a page called “TAXONOMY REVIEW”.

2. Standard B8.B
