Why do Antibiotics stop working? | An NGSS aligned lesson

I have been struggling to rework my lessons to meet the NGSS framework.  It's so easy to just stand up in front of the students and lecture, but I know that is not the best way for students to learn.  I am one who need example lessons so I can model my redesigns around them.  That is why I like exemplars like this.  I can see how it should be done so I know what to do when I am making my own updates. 

This lesson is actually part of a 29 lesson unit so there are lots of examples to look at. Looking at them, they are very detailed (I mean down to the minute).  If you are like me you don't have to make this level of detailed lesson plans.  Despite this, it is something that I want to work on, little by little, and I like have examples like this to look at.  Also, I can test these lessons out with my students and find out what works and what doesn't so I can make changes.

I would love to hear what you are doing to transition your lessons to NGSS (or your state's version of it).

Video Clips for the Chemistry Classroom

I like showing video clips in class because I think it's a good way to grab my students' attention and spark curiosity.  When I can, I like finding clips from old TV shows and movies (not necessarily old to me, but old to our students, lol). 

I usually just save videos I like to a YouTube playlist or bookmark them so I can find them later.  What I have been doing lately is to include them in PowerPoint presentations so that I don't forget to show them.  The problem is that I usually don't want to show the whole clip.  Sometimes I will include a note to myself in the presenter notes of where to start and stop.  There are lots of sites out there where you can clip videos to specific times if that works better for you.

Here are some that I use in my Chemistry class to help you get started because we all know a search of videos about chemistry is going to give you so many results (many that aren't good for the classroom).  Share with us some chemistry videos you've used.
