Kathleen Mortensen 000172880 Integrated Natural Science Applications (INT1) To Freeze or Not to Freeze? A. Project Plan/Problem Statement The purpose of this experiment is to determine how temperature effects the popping of popcorn by comparing storage temperatures and the amount of un-popped kernels. The researcher will ask, “How will changing storage temperatures (independent variables) – freezer, refrigerator, and pantry – affect the amount of un-popped kernels (dependent variable) in microwave popcorn?” To answer the question, the researcher will use seven total bags of the same brand microwave popcorn. Two of the bags will be stored in the freezer, two in the refrigerator and two at room temperature in the pantry.
Int Task 3 Un-popped Popcorn Kernels A. Project Plan I will be conducting an experiment to determine which brand of microwave popcorn leaves the least amount of un-popped popcorn kernels. Problem Statement I will separate the popped kernels from the up-popped kernels and count the un-popped kernels in each bag of microwave popcorn. The independent variable will be the different brands of microwave popcorn. The dependant variable will be the amount of un-popped kernels left over.
*Note that only one kernel of popcorn was used instead of several.

| | Ingredients | 1 12 oz bag chocolate chips (d iry & nut-free) 1 1/2 cups dried cherries (about 1 1/2 5 oz bags) | | Instructions | Put chocolate in glass bowl. Microwave until melted, checking and stirring after each minute. This will take about four minutes. Put cherries into melted chocolate, and stir until all mixed together. Put waxed paper on a cookie sheet.
The independent variable used is the brand of popcorn, and the dependent variable is the percentage of popped kernels per brand of popcorn. Threat Reduction to Internal Validity Threats to the internal validity are anything other than the independent variable that may have an affect on the outcome of the dependent variable in an experiment. In order to reduce the threat to internal validity I used the following steps to maintain the experiment: * I popped three bags of each brand for consistency * I waited 5 minutes between each bag to eliminate over heating * I used the same microwave * I used the same cooking time * I used the same cooking
Take your cookie/jelly pan. Line it with aluminum foil generously. Take the marinated chicken out of your refrigerator, remove one leg piece and shake it up. Let the marinade drip completely. Place it on the cookie sheet/pan (ensure that the skin part covers the chicken).
Each package of Mentos® will be given a different number of dimples. The first package will have no dimples added, so leave the first package alone. 3. The second package will have one small dimple added to each side. Using a sharp, metal skewer or nail, dig into the center of the Mentos® candy to make a small dimple.
You need 3 eggs, a bag of pecans, a bag of coconut, 1/2 stick of butter, a greased 9 by 13 inch pan, a measuring cup, a mixing bowl, and a whisk or an electric mixer. What you want to do first is mix your cake mix, water, oil and eggs in your bowl until moistened. You want to be sure to stir for at least two minutes so you make sure everything is mixed together and you don’t have lumps of cake mix in your cake after you’ve cooked it. If you see lumps, you just have to crush them with a spoon against the side of the bowl. You want to be sure to scrape the sides of the bowl to get all the extra mix off the sides and bottom.
There are four steps in making the icing. In step one heat the butter, sugar, nuts and ginger over medium heat in a saucepan until a paste is formed. Then in step two spoon the icing evenly onto the cake pan. Next, drain the can of pineapple slices; separate and arrange fruit one layer deep on the bottom of the pan on top of the icing. Finally, place a cherry inside each of the pineapple centers.
