Welcome back to class after a long break. I hope that each of you are refreshed and ready for the second quarter. Wow! The first quarter is finished. Do a self check-in: Where am I as a learner getting ready for high school?
Several classes have passed since we performed the phase change lab. Today we will discuss this lab as we begin our discussion about states of matter and phase changes.

October Process Words
Phase Change Lab Review
Lab Process and Error analysis
Tasks:
Process: Look back at your procedures. Did each group follow the procedure? How often did you collect data? Was this too much, not enough? What would be your recommendations for future experiments? What makes your procedure good enough for “anyone” to follow it?
Error Analysis: In each experiment, there are things happen which alter the results of the experiment or possibly affect your outcomes. In this experiment, what are items that could have impacted the experiment?
Your job is to have a discussion regarding this topic and then create a clear whiteboard presentation that examines the process and error of the lab.
Connection to atomic level - solid state
Task - connect the observations that you made to activity at the atomic level. Your focus is the solid ice. What was happening at the atomic level? What did you see? What happened as the ice was placed into water? What happened as heat was added?
Your job is to have a discussion regarding this topic and then create a clear whiteboard presentation (diagrams please!) that examines the this atomic level.
Connection to atomic level - liquid state
Task - connect the observations that you made to activity at the atomic level. Your focus is the liquid water. What was happening at the atomic level? What did you see? What happened when ice was added? What happened as heat was added?
Your job is to have a discussion regarding this topic and then create a clear whiteboard presentation (diagrams please!) that examines the this atomic level.
Connection to atomic level - liquid - vapor transition
Task - connect the observations that you made to activity at the atomic level. Your focus is the liquid water - vapor transition. What was happening at the atomic level? What did you see? What were the first signs that a phase change was happening? What were the bubbles?
Your job is to have a discussion regarding this topic and then create a clear whiteboard presentation (diagrams please!) that examines the these atomic levels and transition.
Graph Analysis
Recreate the graph on your whiteboard and where each state of matter exists. Pick apart the line segments. What happens as heat is added over time? Identify major transition points.

For next class
Several classes have passed since we performed the phase change lab. Today we will discuss this lab as we begin our discussion about states of matter and phase changes.
Objectives:
- Identify characteristics of the three basic states of matter (solid, liquid, gas)
- Describe what happens to a substance when the state of matter (phase) changes
- Evaluate the procedure of a lab.
Language objectives:
- Use the vocabulary inventory sheet to consider the vocabulary words of this unit.
