I performed the "Holiday Trees" lab with my chemistry students. Unfortunately, I was not able to ask for ASU input and review of such class as I am at the mercy of a rotating lab schedule and needed to get the lab in quick.
The lab was an actual introduction to solubility curves so its placement in my curriculum will change for the next school year. All crystals formed and students were able to make hypotheses regarding the evaporation rate in our great state of AZ which they did on their own- (wow- learning that was NOT planned!).
Students took their trees home -lab performed this past Wednesday 12/12/07. This lab was done using materials purchased through MSTF.
Students also created a microsilicate garden and we explored properties of several compounds. We were also dealing with rather minute quantities for a high school lab and I was able to share anecdotal stories with my students regarding the quantities that were used when in the Fromme lab and also bring back the vials of Photosystem I and II that I had shared previously with them.
Indeed, the learning is cyclical and continues to go on. This experience has enriched my life and my students lives so much and allowed me to truly share lab experiences with my students and most of the students seem to love my class because of it! After all, chem is still considered a HS elective and I have 35 students in my class. Not one drop and more kept requesting me!
In the end, the desire and zest for science will benefit the community of ASU, the USA, and ultimately the world!
I took pics but they are all on my low-end cell phone so if I ever find out a way- if it is even possible- to post those here, I will.
Thank you CRESMET for this wonderful opportunity!
