If absent, you can complete the packet using your textbook. Skip the "presenter problem" portion if absent.

Due at the END of next period.
Complete ALL writing in the attached GoogleDoc. DO NOT cut and paste writing from another document or website. Your writing will be inspected with a playback feature to ensure integrity. Writing not completed in the GoogleDoc will not be eligible for credit. You will have a chance to revise your work before your final submission. 

Remember, all writing is completed as an INDIVIDUAL. This is YOUR introduction to the experiment. A sample introduction is not attached to reduce risk of plagiarism. The PDF narrative instructions provide example introductions from different experiments, should you wish to view those.

-----------------
Components of the Introduction:

Stating the Question
What was the purpose of your experiment? The question should be scientific/empirical/testable. Reference your lab planning worksheet. It is fine to phrase it in a sentence using how instead of a true question.
Examples: The purpose of this investigation was to observe how increasing temperature affects enzyme rates. or How does increasing temperature affect the rate of enzymatic reactions?
Stating Hypotheses and Predictions
What did you expect to occur? Reference your lab planning worksheet.
Background Information
Include explanations for all terms and concepts relevant for understanding your investigation and why you made your initial prediction(s). 
Example 1 Experiment testing the effect of wavelengths of light on photosynthesis: basic explanation of photosynthesis, explanation of photosynthetic pigments and absorption spectra, basic explanation of visible light, connection between light absorption and photosynthetic rates
Example 2 Experiment testing the effect of temperature on cellular respiration: basic explanation of cell respiration, explanation of enzymatic structure, explanation of the effect of temperature on rates of reactions and protein structure, connection between cell respiration and enzymes
Knowledge that you have to seek a reference for should be cited. If you can explain the Light Reactions from your memory, you are welcome to leave it in your own words. If you need to reference your notes or the textbook to support your description, those need to be cited even though you rephrase the explanations in your own words. Lectures can be cited in text as (Pierson, 2024), the lab manual (CollegeBoard Lab Manual, 2011) and the textbook (Campbell, 2001).

NOTE: Though the narrative explanation of the Introduction section uses first person "we/I/us," the norm in scientific writing is to not use first person. Try and avoid it, when possible.
Yes: In this study, the oxygen consumption of germinating peas was measured to investigate the relationship between cellular respiration and temperature. 
No: In this study, we measure the oxygen consumption of germinating peas to investigate the relationship between cellular respiration and temperature.
