Description
In this activity you will use the provided template to have students make a paper model of the lac operon. Students will manipulate the pieces to simulate how the repressor prevents RNA Polymerase from transcribing the genes. They will also be able to see that when lactose is introduced into the system, the repressor is inactivated and transcription can occur. It is used in tandem with a fully animated Powerpoint so you can explain what is happening as they are manipulating the pieces. Teacher instructions are included.

Great as review for AP Bio
The powerpoint is really good resource
Unclear. I wasted my money on this purchase.
Like that students could move the pieces
Thanks!
There's an issue with the way the operator and promoter are depicted. The lac operator is DNA downstream from the promoter, which is also DNA. Instead, the materials depict the operator and promoter as if they are large, non-DNA molecules that are bound to each other at right angles and then to the DNA that codes for lac Z, Y, and A (which is anachronistically referred to as "lac X"). As a teacher, you can explain your way around this... but why risk incorporating misconceptions on an already-difficult concept?
These materials might work for lower grade levels, but again, why risk students incorporating misconceptions? It is certainly not sufficient for higher education, the level for which I downloaded it.
Great resource
I loved that students were able to physically move the pieces around and see what was happening in the process.
