6. Repeat steps 1-5 two more times so that you have a total of three trials for this bag of potato chips. Use the same weight of potato chips for each trial. Also, use new graph paper and fresh wax paper on the scale and on top of the potato chips. Record your observations about the size of the grease stains in your lab notebook in a data table.Count how many squares are covered in grease.
Rinse and dry out beaker. 5) Measure 150ml of syrup into the beaker. Make sure egg is covered. Predict what will happen to the egg. 6) Gently place the egg in syrup and weigh it on the scale.
Experiment Date: 11/22/2014 Date Submitted: 11/25/2014 TITLE: Caloric Content of Food PURPOSE: To measure the energy content of various food items, as well as become familiar with energy units like calories and joules. PROCEDURE: First, weigh your empty beaker, fork, beaker with half water, mass of marshmallow walnut popcorn, and the test tube holder. Then record the temp of the water in the breaker. The next thing you do is light the marshmallow on the fork and hold under the beaker making sure to stir the water occasionally. Once the marshmallow is completely burnt, record the temp of the water and weigh the fork with the marshmallow.
Testable Question: What will happen if you put one package of mentos into water, vinegar, or diet coke respectively? Initial Observation and Research: Water, vinegar, and diet coke are different in their composition. Hypothesis: One package of mentos + regular water = no reaction One package of mentos + vinegar = some bubble created One package of mentos + diet coke = an eruption is created with lots of mentos Material and Supply: 1L of water, 1.5 L of vinegar, 2L of diet coke, some stick, 3 packages of mentos, some business cards, some regular paper Procedures: 1. A tube was made by rolling a piece of paper and stick. 2.
HYPOTHESIS: I believe that no matter the amount of jelly on the bread, landing jelly-side down will not always be the case. MATERIALS: 1 jar of jelly 2 pieces of newspaper 1 1oz measuring cup 1 yard stick 9 pieces of white sandwich bread PROCEDURE: 1. Measure the jelly out into the cup so it is filled completely. You will do this three times as you will need to cover one side of 3 pieces of 2. Measure the jelly out into the cup only half way so you can cover only half of the surface of three more pieces of bread.
Since the amount of chocolate covering each peanut isn’t measured out there must be a difference in the mass of the M&Ms. The size of the peanuts would vary as well because there is no set mass for a peanut and nothing can control whether or not every single peanut has exactly the same mass. Methods: The M&Ms for the experiment were collected from an even larger bag of M&Ms. The larger bag was a bag of mixed colors so the color blue was chosen to be the color that we sampled. Five blue M&Ms were collected from the top of the bag and five blue M&Ms were collected from the bottom of the bag in order to give us an even more random sample to work with.
They have a couple different varieties of the candy, but most consist of the same ingredients. For example, the candies have a hard candy shell that is colored in a few of the primary colors, and inside the shell there is a chocolate filling. One of the types of M&M’s has a peanut inside the shell as well as the chocolate filling. As most people know, all the M&M candy taste the same no matter what color shell they have because they’re all the same on the inside. The M&M candy is a medium that I feel can help educate the public about racism and why judging someone based on their appearances isn’t the right thing to

Open up one bottle of your diet coke and place on a flat surface. 2. Open your box of mentos and take out two mints. 3. Drop the mints into the Diet Coke and stand back.
Describe an example of the child’s finemotor skills observed Ashley used the superior forefinger grasp to pick up the half spiked ball and the plush lady bug on the floor. She used the pincer grasp to grasp the cheerio Tara (her mother) had placed on the red plate. With Ashley’s fist she held the spoon at the very top of the handle. Felix used his hands and fingers to link together the link toys and to strum the strings of the toy guitar. Felix was using his small motor development to pull the plush circle out of the mirrored plush wedge toy and then push it back in along with the square and triangle.
