Happy New Year!
New assignments are available on the assignments page. We start off the New Year with a "paper" lab — there is no pre-activity assignment, and you do not need to print off the "element cards" or the "graph paper". All will be waiting for you!

Some lab groups had some difficulty with the precipitation reaction well plate spilling when they tried to turn the plate over to view the results. I took pictures with Elmo of a nicely done plate viewed on a black background and a white background. These may help you interpret your results.

Using my SmartPen with no audio, I wrote out a VSEPR table like the one we did in E-block, started in G-block, but haven't yet started in F-block. You may find it a useful resource for the Molecular Modelling activity you are working on during my absence. I suggest you print off a copy!
