Today you will share, evaluate, and comment on at least two of your peer's lab CER's.
Each of you will be required to evaluate two CER's.
Remember the example that we did as a class to ensure fair grading. (The example is below). Once, complete you will want to read over the next lab and add any vocabulary from the packet into your vocabulary section, and start preparing for your formal lab write up which should be typed up on Word and shared with me.
Today we will be working on creating Bohr models and understanding electron configurations. We will draw models for the first 20 elements on the periodic table to help us understand atomic structure, protons, neutrons, and electrons. We also will need to use the Bohr model to help us place these electrons.
For the PhET CER many of you are feeling challenged, that's good it means you are thinking. Here are a few questions I want you to ask yourself about the question, "What is the difference between chemistry and nuclear chemistry?"
Welcome back to class everyone. After Snowmegeddon and and Mid-Winter break hopefully you are all rested up as we hit the ground running today.
First, we will work with our partners on our initial model for this unit. You will be partners for this entire unit as the deadline for changing seats has passed so hopefully you are ready to work. After you have had a time to work on the model we will be doing the "Build an Atom" lab. This is a PhET simulation lab which you will be working with your partner and has two parts. Part I is about working through the lab and is due tomorrow. Part II (found below) is writing your CERERER (Due at the beginning of class on Friday).
