Teacher Reviews
Here's what a teacher thought of this essay
Awarded 5 stars for excellent scientific knowledge and well planned out methods. Great detailed predictions at the start and clear analysis of the results. Only one improvement would be to add in some background knowledge about alcohols - primary, secondary and tertiary.
