Developing Protocol
VIDEO LINKS:
Lab Experiments (Write protocols based on the videos then complete your protocols as you perform experiments in class):
Data analysis and calculations (Use these if you need help with your data and calculations)
The pre-lab must include Experimental Protocol, Chemical Table and Equipment Table. The lab report includes all sections.Experimental Protocol
(Analysis) Watch the experiment videos. Take notes on the protocol. Stop the video and re-watch as necessary to acquire the details of the procedure. Write out the protocol for each part of the experiment. (It can be written in sequential steps. Complete sentences are not necessary.) This is the protocol you will follow, so be detailed.
Chemical Table
(Representation) Prepare your chemical table including the materials you use in the experiment. Here is a general template that you may use.
| Chemical Name | Chemical Formula | Molar Mass (g/mol) | Hazards | Reference | PPE |
| Sodium Chloride | NaCl | 58.5 | Skin irritation | https://fscimage.fishersci.com/msds/21105.htm | |
Equipment Table
(Analysis) Identify the equipment (type AND size) needed for the experiment and include the name and an image (picture) of each. Be sure to describe the equipment, how to use it, and why it is suitable for this use.
| Equipment Name | Equipment Picture | Intended Purpose |
Data Collection
(Acquiring competencies) Following your detailed protocol, perform all the experiments. Record your observations and take pictures of your key steps in the process. Your observations and images need to be incorporated in your data section and this section should be as detailed as possible as you will use this information to complete your discussion.
Part 1:
(Acquiring competencies) Create slime using the protocol from the video.

Part 2:
(Acquiring competencies) Vary 1 ingredient in a systematic way, observe and record the protocol and results (this can be done with all the ingredients, as long as only one is varied at a time).
