Title: what the lab is about
Background: some information to give context to your reader
Purpose: what you hope to study
Materials: everything needed for the experiment
Procedure: what you do with these things to study the purpose
Data: any numbers, charts, tables or information using numbers
Observations: anything not explained by your numbers above
Error Analysis (optional, but required in college): what went wrong, possible reasons or explanations, when proving something or synthesizing something, what is your yield, percent error, and why
Conclusions: think back to your purpose-what did you discover, how would you improve upon this in the future, what lessons could be shared with others?
Example:
Title: Making Chocolate chip cookies
Background: Home made chocolate cookies are the best, so making them at home is a necessary skill
Purpose: To make chocolate chip cookies at home
Materials: flour, sugar, butter, sugar, vanilla, sugar, chocolate chips (nuts optional, but yucky)
Procedure: Pre-heat oven to 550°F, mix ingredients, test for taste, put blobs on greased cookie sheet and bake for 45 minutes.
Data: 12 totally burned cookies, 25 grams each
Observations: cookies were burnt to a crisp, inedible and quite stinky
Error analysis: temperature was too high, baking time was too long
Conclusions: next time we try this, we should reduce temp and cooking time
