Support it Or Solve it yourself

For our Food course we had to create a presentation explaining either the Pros or Cons of GMOs. I chose to challenge myself and be a Pro GMOs, during my project I found that this was a position with a lot of people defending so I tried to be with it and prove that it is good. I agree that GMOs do provide food and sustenance to be people who don’t have it and have many other values. However I still do think that GMO food is not as healthy as organic food with all the right genes.  Overall I am proud of my project and am impressed by how much research i did to defend such a hard side.

Leavening Agent in a Baking Recipe

May 13, 2013, by

For our Eat course our unit two action project was to create a lab report. We did this to explore the different chemical reactions of food. We made cupcakes and learned how to substitute an important missing ingredient, baking soda. We did this by learning how to create a new leavening agent by having a acid and base ingredient from the pH scale. To replace the baking powder I used olive oil and applesauce. Below you’ll see the results in my lab report. One thing i’m proud of in this project  is doing all the different calculations and the conversions from US metric to millimeters. One thing I really struggled with during this project was making sure that all my calculations are right. Please have a look at my lab report below:

Introduction:

This report will be talking about substituting a leavening agent in a cupcake recipe  by having a basic and an acidic ingredient. I got a cupcake recipe and I had to make it without the baking powder which is the leavening agent. In order to replace this I looked at the pH scale and according to that I got one basic and one acidic ingredient. My first substituted ingredient is olive oil that have a pH of 8 which leads to it being basic. My other ingredient was the applesauce it have a pH of 3.5 that is acidic.  With that I feel that my cupcake is going o have a great apple taste.

Research Question:

My guiding question that I will be answering in the report is, What happens when you replace baking powder to olive oil and applesauce in a recipe?

Hypothesis:

If I mix apple sauce with oil then they will react and make a leavening agent.

Materials/ Ingredients for one cupcake:

  • 1/12 Cup sugar
  • 1/24 Cup butter
  • 1 Egg
  • 1/6 tsp Vanilla extract
  • 3/24 Cup all-purpose flour
  • 1 3/4 tsp Baking powder
  • 1/24 Cup milk

Replacement:

  • 1/4 Olive oil
  • 1/2 Applesauce

Materials:

  • Oven
  • Cupcake Pan
  • Measuring Spoons
  • Mixing Bowl
  • Measuring Cup
  • Whisk
  • Spatula

 

Procedure:

  1. In medium bowl, cream together the sugar and butter

  2. Beat in the eggs, one at a time, then stir in the vanilla

  3. Combine flour and baking powder, add to the creamed mixture and mix well

  4. Finally stir in the milk until batter is smooth

  5. Pour or spoon batter into the prepared pan

  6. Add the leavening agent into each cupcake spot(
    for experimental group only)

Data

Control group:  It is nice and crusty, it is moist from the inside, it rose properly

Experimental group: raised from the edges, sinked  from the middle, sides are crunchy, chewy on the middle.

Calculations/Recipe in Metric:

Formula used:

1 cup- 240 mL

1 tsp- 5 mL

Conclusion:

Overall based on looking at the data I show above I can tell that my cupcake experiment with the leavening agents I predicted was wrong, but it had a great taste. My cupcakes had sunken down from the center instead of rising and the edges is what rose. they had a chewy taste and for my final recipe I had chose cupcake number 6 because it had the apple sauce taste, chewy, and it was crunchy from the sides. With all that I can say it was a great experiment to try and even though my prediction had failed I can still say: It didn’t rise, but it did have a great taste.

Creative Cupcakes

May 13, 2013, by

The purpose of our Food Action Project was to look more deeply into chemical reactions and their impact on the food we bake. We focused specifically on leavening agents, such as baking soda and baking powder. We learned that these leavening agents are what helps our food, in this case cupcakes, to rise in the oven. We wrote a research paper about an experiment we conducted involving the substitution of different leavening agents, using the pH scale. I am happy with the result of my paper and the fact that I was able to complete this assignment with the help of my classmates. To find out more about my research, feel free to read my paper below:

For my first Action Project in Street Math our goal was to relate math to electricity using a real world application.  It was difficult to find an equation that could be related to the real world application of electricity. I did this project by using Pythagorean Theorem to find the length of angled streets. You can see my presentation below if you would like to learn more.




My Garden

April 18, 2013, by

In my food redux course, I created a garden that show foods that we have researched on. My favorite part about this project was looking at different vegetables and flowers and learning about the time they  are planted and harvested.  One main thing I learned in this process is a lot of tips for gardening. Please view my sliderocket below and check out my garden!




Planting A Garden

Garden

My Unit 1 Action Project for my Food Redux course was to create and plan a ten-plant garden, and calculate what the volume of soil for that garden was going to be. I also had to discover and calculate how many living organisms were going to be in my garden creation. I learned about how different organisms interact with each other, and which ones go best with each other. I learned how to calculate living organisms and I was able to gather the confidence to present my garden plan infront of tow U of C professors! I am proud of my garden and what I learned while making it. I now know how to create a fully functioning ecosystem.

The reasoning behind the organisms I chose to plant in my garden is very simple. I wanted an aesthetically pleasing garden that observers would enjoy looking at. My garden is worth planting for many reasons. Not only will it be nice to look at, but also gardens are good for the earth. Gardens help keep the soil clean and nice, and they are a lovely gateway into other things, for example cooking your own meals. Once you being to cook your own food, your friends, neighbors, and family will be inspired to do the same.

Another reason my garden is worth spending time on is because it has many different organisms in it, so there is a lot of variety. There are ten different types of plants in my garden idea, and each goes very well with the other. Happy flowers equal happy and healthy soil. View my presentation below.



Uranium Research Paper by LF

For my unit project in my fuel class, I studied a source of energy and it’s pollutant. In my research paper I wrote about Uranium, my chosen energy source, and the pros and cons of the energy. The purpose of this assignment was to write a research paper, learn the set up of a paper, and prepare for more advanced studies. I am proud of the things I learned about Uranium and the extra research I did. I learned that this specific type of paper is very hard to write, and requires a lot of information and research, hence the name “Research Paper.”

 

Introduction

In this paper, I will talk about an energy and its pollutant. The energy I was assigned is Uranium (Uranium is a relatively common metal, found in rocks and seawater), and a pollutant that comes from it is radioactive dust. I will discuss its pros and cons, and its relationship to the carbon footprint. A basic nuclear equation is 235U + 1 neutron = 2 neutrons + 92Sr + 140Xe + ENERGY. In that reaction, 1 neutron splits the atom. When the atom is split, 1 additional neutron is released.

 Math and Carbon Footprint

Living on earth, we use many different types of energy. Some examples of these are gas, oil, electric, propane, and wood. The usage of all this energy and how much a person uses is called the carbon footprint. When using these resources, according to the EPA (Environmental Protection Agency) calculator, my own carbon footprint would be 20,852 lbs. CO2/year.
This relates to my pollutant because during the production of nuclear energy, Uranium is present and radioactive dust is emitted into the air. Uranium is related to some people’s carbon footprints, however not mine, because I don’t set off bombs.

 Pros and cons of Uranium in the environment

It’s easy to come across cons in terms of the use of Uranium. For example, it is not reusable. During my search for the positive effects Uranium has on the environment, I came across something interesting. Uranium power is being looked at in a new way, according to an article written by Jim Thomas. Jim speaks about benefits of using Uranium. He explains, “The most obvious benefit is the large reduction in carbon dioxide emissions in comparison to coal or natural gas fired power plant.” Another fun fact I discovered is that it is also used as a shield against radiation, even though a byproduct of Uranium is radioactive dust.

Conclusion

In conclusion, I thought it was interesting that Uranium was being viewed in a new way, and different ways of using it were being discovered, however Uranium does not have a good impact on our environment. There are a lot more negative side effects than positive ones. For example, the radioactive dust emitted when mining for Uranium, and its negative impact on the plants and animals around the mines.

A story about a pendulum

March 7, 2013, by

For my final Action Project in my math and science class (Light & Sound), we all learned about a time keeping device, I chose the pendulum.  This was an extremely interesting project, mostly because I got to research Galileo, who in my opinion is the best engineer ever.  Although this project was interesting, it was hard to figure out the math of the concept.  Building the prototype of a pendulum was equally difficult.  See my report below.

 

My device looks is a pendulum.  It consists of two metal poles to hole it up, and a rope with a metal bar on the end to go from side to side hitting the metal poles and making a sound.  Every one second it hits the bar, each time it hits the first bar, hits the second bar, and goes back to hitting the first bar it completes one cycle.  The math behind a pendulum is pretty simple once you figure it out:

 1 cycle equals three seconds.
30 cycles equals one minute.
1,800 cycles is one hour

X = Cycle
Z = Seconds

10x = 30z
100x = 300z

In 1602, The Italian scientist Galileo Galilei studied the property of a pendulum. Galileo discovered the crucial property that makes pendulums useful as timekeepers, called isochronism; the period of the pendulum is approximately independent of the amplitude or width of the swing. The pendulum is an extremely key device in history for timekeeping. When Galileo invented it, it was instantly a famous and amazing idea. It goes on forever all by itself and requires very few materials. When technology wasn’t available back in the 1600’s, a sundial was the most precise timekeeping device.
