Lab Experiments (Write protocols based on the videos then complete your protocols as you perform experiments in class):

1. Weighing
2. Measuring Volume
3. Making Slime

Data analysis and calculations (Use these if you need help with your data and calculations)

1. Measurements
2. Significant figures

Bring 2 printed copies of your protocol developed during the Developing a Protocol session.

Part 1:

(Lab skills) Create slime using the best protocol you created from your last lab class.

(Lab skills) Presented protocol: (include the protocol from your own group in as much detail as was presented)

(Analysis) Performed protocol: (add any details that you added to the presented protocol when it wasn’t explicit: ex. stirring, order of mixing, length of time between additions, mixes, etc.)

Part 2: Create slime using the protocol from another group that was created in your last lab class.

(Representation) Presented protocol: (include the protocol from the other group in as much detail as was presented)

(Lab skills) Performed protocol attempt 1: (add any details that you added to the presented protocol when it wasn’t explicit: ex. stirring, order of mixing, length of time between additions, mixes, etc.)

(Lab skills) Performed protocol attempt 2: (add any details that you added to the presented protocol when it wasn’t explicit: ex. stirring, order of mixing, length of time between additions, mixes, etc.)

1. (Analysis) Identify the variable(s) that you changed in the slime-making experiment.
2. (Analysis) Describe the effect each change had on the created slime (texture, color, stretchability, stickiness, etc.) (You may use pictures as supporting evidence, just make sure that you add captions to each image.)
3. (Analysis) Compare your slime from last lab class to the slime you made today following your own protocol. (You may use pictures as supporting evidence, just make sure that you add captions to each image.)
4. Analysis) Compare your slime that you created following another team’s protocol to the slime the other team created following their own protocol. (You may use pictures as supporting evidence, just make sure that you add captions to each image.)
5. (Analysis) Compare your slime that you created following your own protocol to the slime another team created following your protocol.
6. (Assumptions and analysis) Fill in the following table using the observations and data from your experiments.

Write a minimum one-page (12 font, single spaced) discussion on the experiment conducted this week.  The assignment will be graded on completeness, clarity of the explanations and the meaningful integration of the collected and calculated data. Correct grammar and appropriate format for the chemical formulae and chemical reactions is expected. You may use the outline included at the end of this document on how to build your essay to address each category.

1. (Existing knowledge, research, and views) Slime is a polymer. Define a polymer and give at least 3 other examples of polymers you encounter every day.
2. (Analysis) Identify the monomer in this polymerization reaction.
3. (Existing knowledge, research, and views) Identify the role of the contact solution, glue, and baking soda in the slime formulation.
4. (Lab skills) Describe how you varied on component while holding the others constant in the process.
5. (Analysis) Give a supported argument why it is important to vary only one component at a time in an experiment.
6. (Experimental design) Propose another experiment to modify your slime protocol. Don’t hesitate to test your protocol and share your pictures!
7. (Analysis) Identify at least one other area of your life where having a clear and detailed protocol is essential. Don’t hesitate to provide a sample protocol!
8. (Acquiring competencies) Based on your experience reproducing your own and your colleagues’ experiments, describe how much detail was or would have been helpful in the provided protocol to confidently perform the experiment.
9. (Acquiring competencies) Based on your experience reproducing your own and your colleagues’ experiments, describe how much detail was or would have been helpful in the description of the product to make you confident in your ability to reproduce their results.
10. (Analysis) Describe at least one take-away from this experiment that you will use to improve your experimental protocols or data collection process for future experiments.
