Constants? White Potato

Temperature (Manipulated )or Dependent Variable?

Aluminum Foil and & Zip Lock Bag -Independent Variables Experimental Design 1. Gather materials
2 Cut potato halves
3. Place in refrigerator for 1 hour
4. Take out and sat on counter @ room temp for 5 mins
5.Used kitchen thermometer to check temp
6.One half in foil & other half in plastic

Background Research Hypothesis-I think aluminum foil will keep things colder because of the physical make up of aluminum foil compared to that of plastic which is clear and can be seen through. If then aluminum foil on the other hand can not be seen through therefore I think this is why aluminum keeps things colder because it is protected from the light slowing down drop in temperature. Hypothesis
Purpose- The purpose of this experiment is to find out which product keeps things colder: aluminum foil or plastic wrap. To investigate, one items (white potato). One item will be placed inside a plastic bag and one item will be wrapped in aluminum foil. At the conclusion of the experiment, the results will help determine which was is the best at keeping items cold. Purpose Topic was chosen to give a picture of what my project is about and the object that I will be using to show the outcome Jawaun Brown

The at the end of the experiment the aluminum foil kept the potato colder because of the physical make up of aluminum foil compared to that of plastic bag. The temperature before and after removing the potato from the freezer stayed almost the same or colder when in the foil, but the temperature dropped while in the plastic bag. Conclusions White Potato
Foil
Zip Lock Bag
