Science Homework Help

1. Title (1 pts):Title including date

2. Objective (4 pts):Indicate the purpose of the experiment (Example: To separate the components of a dye solution using chromatographic techniques)

3. Principle (5 pts):Explain the theory behind any techniques used. If a reaction occurs write out the complete reaction. The reaction scheme should include the masses, moles, molecular weights, and theoretical yields of the reactants and products under the chemical structures. (Example: Column chromatography separates mixtures using mobile and stationary phases based on the polarities of the components within the mixture.)

4. Procedure (5 pts):Write the procedure of the lab in your own words. 

5. Observations (5 pts):Note any observations from your experiment. These must be written in ink during the lab period and attached to the report when it is turned in. (Example: The color bands of the dyes within the column).

6. Discussion (15pts):Describe observations here. Explain any observations that do not agree with referenced values. (Example: Contamination of dye solution may have caused components to be unexpected color).

7. Results (5 pts):A very short statement of the results from your experiment including percent yields if applicable. (Example: 3.52 g of pure white caffeine was obtained with a yield of 73.6%).

8. Post-Lab (10 pts):Any post-lab questions assigned should be answered in this section.
