Saving the Yeast

How would you try to protect a strain of yeast that was particularly sensitive to UV light?

Our Biology students designed their own experiments to compare methods.  Is expired sunscreen okay? Would sunglasses work? How effective is UV blocking clothing? Would aloe vera provide the same protection as a sunscreen formula? Will spray sunscreen protect better than lotion?  Does “natural” sunscreen produce better results?

The posters they presented below show their experimental results.
