Independent variable
The independent variable for the experiment is the Styrofoam, cotton balls and house insulation.
The dependent variable for the experiment is the temperature changing and the water melting. The Controlled variables are the box, the temperature of the hot water before it is going to be placed in the lunch box and the size of each lunchbox.
Purpose
For me, enjoying a perfect lunch is to have a perfect meal. All, meals need to be either cooled or heated. Without it, many people can't enjoy food like they do at home. Some might even choose to go for a less healthy choice. I would always have a rock hard lunch in winter and a melted soggy dessert in the summer. When I tried looking online for a heated lunch box, all of …show more content…
Make sure you repeat steps 1-3 so in the end you have three lunch boxes.
5. After that, take your Styrofoam block and place it on top of one of the halves of the cereal box. Align the Styrofoam and the lunch box together and cut off the extra Styrofoam piece that is not under the lunch box.
6. For the Styrofoam insulation, take your container and create an outline of the container size on the Styrofoam.
7. Later, take your blade and scrape all the Styrofoam off the marked area. Doing this, you will be able to create a small hole where your container will perfectly fit.
8. Then take your Styrofoam piece and place it in one of the cereal boxes, creating the Styrofoam insulation.
9. For the cotton insulation, open the cotton bag and place all of the cotton balls on the bottom of the box. Then, use your hands and create a small hole big enough for the container to fit.
10. Later, place a bag so it is covering the cotton balls and it is covering the hole. Next place the container in the hole of cotton balls.
11. To create the House insulation lunch box create a whole layer of house insulation at the bottom of the box. Make a hole so the container can perfectly fit inside the lunch …show more content…
For the cotton balls in 30 minutes it lost 0.8 millimeters of water from the ice. When another 30 minutes past only 1.25 millimeters were melted. In a total time of one hour and thirty minutes 15 millimeters were melted from the ice cube. When two hours passed, the ice cube lost 17.5 millimeters and when two hours and thirty minutes past 22.50 millimeters were melted. Finally, when three hours passed 27.5 °c millimeters melted. The original temperature for the hot water was 87°c and when it was in the lunchbox it became 45 °c. When one hour passed the temperature of the water became 40°c. For the house insulation, in thirty minutes it lost 0.5 millimeters of water and in an hour it lost 1.25 millimeters. In an hour and a half it lost 10 millimeters, in two hours it lost 17 millimeters and in two hours and thirty minutes it lost 21.25 millimeters. Finally, when three hours passed 34 millimeters of water was melted from the ice cube. After thirty minutes, the house insulation became 50°c and when one hour passed the temperature was 42 °c. Out of the three insulators I used the best one was the Styrofoam. When thirty minutes passed only 0.5 millimeters of water melted. One hour passed and 1.25 millimeters melted. In an hour and a half 10 millimeters melted and in two hours 16 millimeters melted. Finally, in two hours and thirty minutes passed 19 millimeters passed and in three
