Ethics in Science assesses whether the actions of a scientist were ethical by examining scenarios and describing why each scenario was or was not ethical.

Six teachers share how they approach labs in their physics classes. Thank you very much to Laura Zeller, Shaun Thomas, Will Segal, Janel Morris, and Nick Sourvelis for collaborating with me on this project!

This is a demonstration of how to make combinatorial polymer scaffold libraries for rapid screening of cell-material interactions in 3D. This approach will help accelerate the developmentof new devices for tissue engineering applications

Here, I explain the results and theory underlying mannitol salt agar. I also show a flow-chart that guides the student in interpreting the result correctly.<br/>

In this video, I explain how to determine resistance (R) or susceptibility (S) in bacteria using the disk diffusion method (with bacitracin and optochin).

The video is the second out of three lecture presentations on an experiment involving amylase and pH. The presenter introduces Catherine, who performs the experiment and collects results. Equipment for the experiment is shown and...

The video is the second of three lecture presentations on the amylase and pH experiment. It shows Catherine carrying out the experiment and collecting results. The presenter begins by discussing the equipment that Catherine is using,...

In this video, we will discuss the 1) results & 2) theory underlying the nitrate reduction test (nitrate broth).<b<br/>r/>

Results are first, and theory (somewhat compli<br/>cated) begins at 7:55.

As always, the steps of putting a gene insert into vector/plasmid AND nickel affinity chromatography depend on your specific lab and protocol. Here, we look at the general theory of engineering a poly-His tagged protein and Ni affinity...
