Problem Statement
Penelope O'Meara will uncover the chemistry behind saponification to help create an eco-friendly, 21st century, side-hustle at Northern High School from January 1st, 2022 to February 17th, 2022. She will utilize programming tools to develop a soap dish design and prototype, and she will create efficient processes for the creation and packaging of soap.
Constraints and Limitations
Product produced should be sold at a profit
Students should use tools provided or tools from home to produce the product
Products must be made at school under the supervision of Mr. Krieg
Brainstorming
Company Name Brainstorm
Soap Dish and Soap Brainstorms
The Process
Gather the oils into a glass bowl and place them on a hot plate. Turn the hot plate on.
Mix the Sodium Hydroxide and DI water. Heat and monitor the sodium hydroxide and DI water's temperature and Oil's temperature until they are around 5°C of each other.
Obtain the required charcoal and prepare to add it to the hot oils.
Add the charcoal to the oil mixture while mixing it in.
Pour the sodium hydroxide carefully into the oils mixture.
Pour the soap into the mold when trace shows.
Draw a pattern on top of the soap and set it in the fume lid to cure.
Cut the soap block every 2.5 inches.
The Final Products
Orange Creamsicle Soap
Peppermint Charcoal Ying and Yang Soap
Seal Soap Holder
Seal Soap Dish CAD File and Isometric view.
The Next Step for Production
Most Important Artifact (Document)
The most important document from the production team was the improved procedure for making soap. The detailed procedure helped quicken the process of making soaps which leads to an increase in the supply of soap, and ensures that packaging and shipping soap can be carried out in a timely manner. Overall, with the crafting of soap becoming more efficient, Handmade in the Hills (HHM) can sell more soap--adding to the overall profit of HHM.
The next production team should focus on several things:
Creating a procedure for soap orders
Buying the items listed on the shopping list that is on the slideshow
Creating a procedure for online soap orders once HHM goes virtual
Re-counting inventory
Creating a procedure for the first step of the process (measuring out the oils)
Reflection
I applied a lot of chemistry concepts and skills in this project. I used stoichiometry, dealt with specific temperatures, and mixed substances together with the goal of making natural soap. I also had to figure out the potential dangers while making soap. For example, essential oils are extremely flammable and combustible; so when we made our soap, we kept the essential oils far away from the hot plate to avoid an explosion. Another instance would be when we used Sodium Hydroxide—a dangerous chemical. It has the potential to burn off skin, so we exercised lab safety by wearing protective clothing (gloves, long sleeves, long pants, and safety goggles).
Individually, I succeeded in reaching out to people to sell soap. I made 8 sales that totaled 29 soap bars with a profit of $159.50. As the production department, we created procedures that increased the efficiency in making and packaging soaps. The new procedure we wrote is being applied to the soap-making process for the next group. As a class, we successfully made high-quality soap and made a profit of ~$500 in two weeks.
