Modeling and Street Tacos

Modeling attempt

Show the kids an event. Have them develop a model. Have each kid draw and write about the model and force them to ask themselves if this model can explain the event. As a teacher, first say something nice about it and then look for their misconceptions and use this as a formative assessment. Combine the individual models with others. Slowly build a larger model and constantly ask if this really explains the event.

Reflections from Kinetics - Solidifying Why I Teach Method of Initial Rates AND Integrated Rate Laws

I taught my students how to use the method of initial rates. I taught my students rate laws. However, they strugged to differentiate when to use what method. Upon further probing, they struggled to articulate why one might use one method over the other. They could parrot back some ideas ("The rate law tells you about the particles involved in the rate determining step of the reaction."), but I wasn't convinced of mastery and connections.

Mystery of Matter - Facilitating Discussion

I used the teacher guide for the Mystery of Matter video series to create worksheets for students to complete while watching the first two episodes. This can be used if you are leaving the video as a sub plan or if you want to assign the video as a homework assignment. It would also work as an assignment for absent students if you watch the video in class whether you use the worksheet with present students or just guide the discussion per the original teacher notes provided on the Mystery of Matter website. Using this format, you can create your own worksheets from the teacher guides of the other episodes as well.
