Reflection: Pacing Mixtures: Characteristic Properties - Magnetism and Solubility - Section 4: Lab Prep


Often, I find that the constraints of  time make decision-making difficult in the classroom. This day is an example of that. With more time, I would do these labs on separate days with more discussion and in-depth work on conclusion writing.  

However, with only 10-15 days for this unit, I couldn't take the time. I found that over 75% of the students did well on both the labs, indicating that they could handle the truncated schedule. Yet, that does mean that 25% of the students did not. It makes me wonder if those students needed more processing time. Next year, I might try differentiating this lesson by having some groups do both labs and some do only one.

Mixtures: Characteristic Properties - Magnetism and Solubility

Unit 8: Mixtures: Characteristic Properties
Lesson 3 of 11

Objective: Students will be able to identify the characteristic property of magnetism and solubility and use it them to separate two simple mixtures.

Big Idea: Separation. Getting the peas away from the carrots.
