Conclusion - be sure to explain day one's results, as well as the food table.

Attention 7th, 8th period:  I retested egg whites with Benedict's solution.  The test was negative (the liquid remained blue).  Our classroom sample was somehow contaminated.  Please reflect on this in your lab write-up (potential source of error).
