1.  3/21 - DNA: DNA is the ‘instruction manual’ for all of life’s processes. In order for the body to ‘read’ these instructions, each cell must undergo a process of DNA replication and protein synthesis (transcription and translation). Using the documents provided, describe the process in which the instructions in DNA create proteins.

2.  Acid Base Test is THIS WEDNESDAY  Last week’s packet is due Tomorrow!  Gateway is NEXT MONDAY

3.  RELAY FOR LIFE COMPETITION!!!!!!!! : ) ◦ We will collect $$$ from all classes everyday this week. ◦ You will get an update each day of totals from all classes. ◦ Winning class receives specialty cupcakes provided by me and class free time. Maybe even a surprise thrown in by Mr. Jefferson too! : )

4.  When you glue your indicator paper to your worksheet, use as little glue as possible to make it stick.  Record the color of the pH paper immediately after you take your sample. It will change over time if you wait.  You only need 1 drop when taking our sample.

5.  pH scale: measuring pH indicates whether solutions are an acid or base.

7.  3/24  In order for an ecosystem to develop, it must undergo certain stages called “succession.” Primary and secondary succession must occur in order to produce a climax community. Using the document provided, describe the process in which an ecosystem changes over time to create a climax community. Write a paragraph about succession.

8.  Open up to 3/19  Around the room are pictures. Use these to check the correct boxes for each topic.

9.  Test Tomorrow!  Packet 7 moved to Thursday  Study Guide is due Thursday with the packet  pH Lab from yesterday is due THIS FRIDAY.
