General Remarks: You are encouraged to work in pairs to complete the labs. However, copying from other pairs will not be tolerated and will be penalized accordingly. Accuracy in calculation, neatness in presentation and rigor in explanation all count! You are engaged in a science — be as accurate and precise as you can be. Please consult your Instructor if you're unsure of what's expected of you. Show all work! Show all your calculations where a quantitative answer is expected. Simply writing down a number for an answer will not receive credit.
