PROJECT DUE THURSDAY....
ALMOST DONE! yaya. I understand heat waves.... and what it has to do with making cookies.

I am almost done.... yayayayaya. Today I downloaded the videos of the cookies baking and I have gathered all my information/ observations! I am ready to finish the project and make the poster and perfect everything :)

I can't wait to show everyone!

I am almost done!! I cleaned the oven and I am ready to video tape my cookies being made!! The final result with cookies being related to physics is almost done!!

INFORMATION FOR FINISHED PROJECT

• convection oven has a fan that circualtes the heat/ air movement and a regular oven does not
• the formal definition of a convection oven is: a cooking device that cooks the food because of the circulation of hot air from the fan
• because of the fast moving air the convection oven doesnt have to be on as high of a temperature as a regular oven, and the food will still cook in a fast time.
• the fan in a convection oven works well because the fan circualtes the hot air and cook the food more evenly. The convection oven elminates "hot spots".

Next task:
video tape the cookies being made in convection and regular oven.
then...

• observe the difference (hopefully there will be a noticable one)
• make a diagram showing the waves in the oven and explaining the process of why it works this way ext..
• PERFECT IT.

Today I evaluated what I am going to do with the finishing of my project. I researched what convection literally means, and now I am going to make the distinctive differences between both ovens. I also am going to make the cookies and take a video of them in the oven. hopefully the video works out and you can see the cookies being made, and what the heat has to do with it. I am exciting to finish my project and make the final steps on my project! Physics in making cookies is almost done!!!!!! :)

 This website is all about heat transfers, with definitions of Convection and conduction.
In my experiment I am using a convectoin oven, so this website made things more clear for me.
In convection heat transfers this is what happens:
The heat transfers is by the air or water moving away from the heat source taking energy with it.
Convectoin above a hot surface happens because the hot air expands. It becomes less dense and the heat rises, cooking whatever you are making! :) I think that the convection oven works because the heat waves in the oven rise, with energy transfering with it. This I believe is what makes the cookies in the convectoin oven
Over the next few days I am going to research more about making cookies in the oven and connecting it to these facts I learned today. So I don't have to say "I think or I believe" I will be able to say "I know."
This diagram below is examples of Heat transfers. It gave me an idea of what heat transfers go on in a persons everyday life.

To be able to explain and present my physics project on making cookies I need to understand convection and conduction. These are two forms of heat.
For my project I will be using a convection oven, so I need to research and figure out how the heat in the oven cook the cookies, and make them so wonderful. :) Also as a physics student I am going to learn about all the ways physics plays into baking this treat.
For my final presentation I am going to create a poster that explains all the ideas I have stated above. Hopefully I will also be able to bring in some cookies!

First Post

Today I made my first blog, it was easy and now i am ready to start my project. My project for this semester is going to be about making cookies and the physics behind it. Im interested in testing it out, and learning about how our everyday activities (making cookies is frequent for me) play into the world of physics.
