How can different emulsifiers change a recipe?

Welcome back to my blog. This post is about the second Action Project from my Food class in the STEAM course. In this unit we worked on some math such as variables, exponents, and conversion factors which would become useful for the action project. Leading up to the AP we created a couple kitchen experiments. Our first experiment had to do with leavening agents. We created a "porridge" that was supposed to be similar to making the first bread that our ancestors had made for food with seeds. After creating the porridge I added a banana which could help bring bacteria to the "porridge" so it can rise. The second experiment involved changing emulsifiers. In a brownie recipe we changed eggs with a banana and created two tests. The first test had all the usual ingredients and the second one had the replaced emulsifier. After baking we found the banana test was a different texture than the original test. For this AP we were asked to use a recipe of our choice and replace one of the ingredients with its similar subject like an emulsifier or leavening agent. I chose to create a cookie recipe and change out the emulsifiers. This experiment will be expanded on in the slideshow below.



This Action Project involved a lot of science and math. I enjoyed working on the in-class experiments and collaborating with my classmates in discussion was useful for this AP. Before this was posted we presented what we had for the AP so far and it was nice to see what recipes my classmates had done. While going through this experiment we were required to have some pictures of the process and the final result. Those photos are below. I thought working on this AP was fun. I enjoyed working on some of the math that I still remembered from my eighth grade math class and I thought the science was nice to learn. The emulsifier and leavening agent experiments are really easy to create especially the emulsifier one. If you want to try it for yourself all you need to do is find a recipe and change out one of the ingredients that are emulsifiers. If you follow the same baking recipe you will see some differences and possibly something similar. I hope to see you in the next post.

Input Manipulation Using Python

Welcome back to my blog. This post is for the projects in the Computer Science class. In Computer Science we have been learning about different types of coding and how computers work. We have done math problems in binary code and practiced making something from using python. In these two projects we used python to code a advanced calculator that you can use to find what the temperature in Celsius is based off of your input of your temperature outside in Fahrenheit. The second project here is a code that uses your inputs to create a letter to a state representative to talk about something important to you. Both of these codes have been checked multiple times to see if there were any errors or changes that needed to be made. If you would like to try them out for yourself you can do so by typing in your responses on the right to the questions that are asked. The first project is an advanced calculator that takes an input of a given temperature in Fahrenheit and converts it into Celsius fo...

I Am a Peacebuilder

This post is for the Civic Term class Global Peace. In the three weeks of this class we covered sarvodaya, satyagraha, and Sharpe's 198 Nonviolent Methods of Nonviolence. Sarvodaya and satyagraha were concepts by Gandhi. Sarvodaya explains that all are rising and is supposed to be an answer to all "isms" such as capitalism or communism. The large list of nonviolent methods consists of speeches, marches, strikes, physical interventions, peaceful noncooperation, boycotts, and more. For this project I chose to focus on homelessness in Chicago. In the large city you can find tent cities or people camped on the street in many places. With the weather in Chicago living outside with only a small shelter or none at all can be difficult for surviving. The city is also dotted with empty lots or abandoned land. I believe these plots of land can be redesigned into housing for the homeless. Each person or group of persons depending on their situation would have a small residence where...

The USS Hermit, A Ship to the Future

Hello, this is my Action Project for the class Redesign the Future. In this class we have covered climate change, Bill Gates' 5 Grand Challenges to tackling climate change, circular economy, systems thinking, and some of the Sustainable Development Goals. In this unit we went to The Plant Chicago where we learned about aquaponics, The Hive which talked about bees and their struggle against climate change, Friends of the Chicago River that taught us about our river and its history, Rheaply which showed us their company and an insider view of circular economy, and the Lincoln Park Zoo which told us about select ecosystems and habitats for their animals of all kinds. This unit went very in depth on the concept of systems thinking. We talked about certain actions that were made to solve problems such as the malaria in Borneo but the unintended consequences that followed and how to solve them. This AP is about a design that follows one of the 5 grand challenges and also how can you solv...
