Reflection: Accountability Mixtures Labs Day 2: Separating Mixtures and Rates of Dissolving - Section 7: Closure: Separating Mixtures Writing "Put Your Finger On It"


Peer editing is a valuable piece of the writing process.  There are so many benefits that result from this type of practice.  First, without creating time for it, middle school students tend to be in a rush and neglect to take part in the revision process.  Taking time to revise writing will dramatically improve the writing of your students.  What I have learned from using the "Put Your Finger On It" tool, is that it is those students that cannot effectively write that benefit the most.  

For some students, they are not even aware of what effective 7th grade writing looks like.  Simply reading other student's work that reflects mastery, can provide them with a model to improve their own writing.  Furthermore, with this specific strategy, students can make realizations about what they do not understand.  If you hold students accountable to actually physically "put their finger on" the criteria, they often realize that they don't know what some of the criteria are.  For example, students might raise their hand and say, "How can you be sure that 'the discussion explains how the lab supports the claim'?" or "What does it mean to 'have a clear claim'?"  In asking these questions, I can provide individual support to students and students can identify the pieces they don't understand themselves.  Often after explaining questions like these (even though they are editing other students' work), students respond, "Oh!  I need to fix that in my own writing too!" Thus, peer editing not only pays dividends for a current piece of writing, but it can serve as a process to improve students future writing as well.

Mixtures Labs Day 2: Separating Mixtures and Rates of Dissolving

Unit 4: Physical Properties: Molecular Arrangement and Phase Changes
Lesson 3 of 12

Objective: Students will be able to write a detailed procedure and model various methods that mixtures can be separated by physical means.

Big Idea: Students develop their own procedures to separate a mixture and then carry out their plan using lab tools of their choice!
