Quiz Reminder

Honors classes: you have an open notes quiz on Friday which will count towards a notebook grade. We will not be swapping notebooks like we did for the last quiz: you will keep your notebook for the entire quiz.

General class: your quiz is on Saturday, on Friday we will be making up the "What happened in the eggsperiment" sheet.

No 54321 due this week

Because of the short week and the quiz on Friday for Honors and on Saturday for General, there's no 54321 due this week.

Parents Weekend

Today we had open mini classes for parents to come see what we're all about. Here's what we did:

A Block played the board games they made yesterday (see below).

B Block did a mini microscope lab looking at onion and cheek cells (thanks Ms. Goodrich!)

C Block played photosynthesis trivia and read a short article about the pastures of the seas.

E Block played bio jeopardy hosted by Alex.

Biology Board Games

Today during A block, students made biology boardgames using their knowledge of cells and macromolecules. The plan is to play their orginal games with their parents tomorrow. You can click on a picture to make it larger.




Science Sidewalk

It was a b-e-a-utiful Friday afternoon but B Block had a test coming up. The compromise: make chalk murals on the walk between Meservey and Berry to review.

The Great Eggs*periment

Check out the Great Eggs*periment (aka: how we saw osmosis and diffusion in action).
