DO

1. Look at the pictures and videos below. 

2. Look at the picture of the notebook and study the observations that were made by students in the class - Basically MAKE SURE you get to see what everyone else got to see. 

3. Read the guiding questions at the bottom of the page and THINK about them for a few minutes.  What ideas did you come up with? 

4. Do Journal Entry 1-3 /1-4 in classroom.  We did the water and electricity part as a class to work on writing and evidence-based argument and we agreed on the observations and the claim for steel wool.  The assignment for students was to work on the Why section for steel wool.  See this link 

DO NOT 

1. Look up information about this.  This class is about the process of science, developing thinking skills, and constructing explanations.  It is not about answers.  If you look up information you will still need to explain the process using only the evidence from class. 

1. Remember from 7th Grade:  All matter is made of particles (atoms and molecules).  When you are trying to make sense of the observations of steel wool, PLEASE think about this from a particle perspective.  In other words, do not think about the steel wool as a clump of wire, this of it as atoms.  

2. The steel wool has different characteristics before and after being burned.  What might that mean? Recall Mystery Powder takeaway. 

3. What understandings from Water and Electricity might help to understand the observations made of the steel wool?

4. What determines the weight of an object?  What would have to change for the weight to change?  How might that help you think about steel wool on the scale? 

5. In the bell jar, oxygen levels decreased during burning. Where was the oxygen that the sensor was measuring?  Now that their is less oxygen, where could those oxygen particles be?
