Grade: 7, 8
Hypothesis: If the center of Earth was solid/liquid and edible, then the layers would consist of graham crackers and Jell-O. Experimental design:
Materials: Graham crackers
Tooth picks
Whipped cream
Food coloring ( blue green)
Paper sticky notes
Jello, premade or powder
Red (inner core
Orange (outer core)
Yellow (mantle0
Plates bowl
Procedure:
1. Gather all the ingredients and materials needed for the experiment.
2. Make the jello (if the jello is powder). If the jello is already premade start mushing the jello. Don’t break too much.
3. Put graham crackers in a zip lock bag and smash it with a hammer until it is fine. After they are smashed or processed, put them in a bowl and put it aside. …show more content…
Take the jello recently mashed jello and add them to the plate/bowl. Layer them according to the colors. (Yellow for the mantle, orange for the outer core, and red for the inner core.) Then add the crushed graham crackers to represent the crust.
5. Put some whipped cream in a bowl then add 7 drops of food coloring. Stir until you get the color needed (blue green). Add more food coloring if necessary.
6. Label each part using the toothpicks and paper/sticky notes. Enjoy eating!
The dependent variable was making earth with jello and graham crackers. The independent variable was changing the outer layer of earth using graham crackers and whipped cream.
The control of the experiment is the layers of earth and the constant is keeping the jello and crust in place. Data
