Slime Lab Report

Materials: Observation 1; 1 cup of water, 2 cups of sugar, 1 glass jar, 1 wooden skewer, 1 plate and 2 clothespins. Observation 2; 1 cup of water, 3 cups of sugar, 1 glass jar, 1 wooden skewer, 1 plate, 5 drops of red food coloring, and one plate.

The materials that were used/needed in this experiment were a penny, water, soap, rubbing alcohol, a pipet, and a beaker.

Students will place a potato cube into a test tube and add 3 ml of H202 into each tube. Then students will wait one minute and record the height in cm of the bubbles and rate how rapidly the solution bubbles on a scale of 0-5. (0=no reaction, 1=slow,……. 5= very fast.)

The materials used during the experiment included three plastic cups, three gummy bears, masking tape, marker, balance, calculator, tray, one plastic spoon, a measurement tray, and a ruler. The three plastic cups were used to hold the tap water, salt water, and sugar water. The masking tape and marker were used to label each cup with the

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Next, during the experiment, it was observed that the hole in the lifesaver was not big enough for Sam to go through it. It was also observed that Sam and the lifesaver were both very fragile in the sense that they could be reshaped or stretched easily. In contrast, during the lab, it was observed that to go through with the procedures four paperclips are needed. Further, into the lab, it was noticed that the lifesaver needed to be stretched at least 4 more mm for sam to go through the lifesaver. The hypothesis was proven to be correct because after reshaping the paper clips from their original form it was

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

We first started this experiment by obtaining twelve 15ml test tubes, in which we placed in a rack and labeled each with what

Pictures will be provided of the experiment. Materials used in obtaining the pictures are a bag of regular (NOT peanut) M&Ms (about 8 oz), plastic vernier caliper, and 100 ml plastic graduated cylinder.

I will purchase all the materials for the experiment and then perform the experiment. I will pour oil in three bowls and then out each detergent in a bowl. Pictures will be taken after each detergent is in a bowl. I will also observe all three bowls after and se which detergent broke up the oil the best. All data will be recorded in the data table.

It used mass, temperature, length, volume, density, and making a dilute solution. I learned the importance as well as the difficulty of making proper measurements in a lab setting. If one measurement is off, it will throw the entire equation off. This will give either incorrect or inaccurate results.

This experiment was to test what is in each part of a Big Mac. The test was to see what macromolecules are in each of the ingredients. The ingredients that were tested were lettuce, special sauce, pickle, onion, cheese, meat, and bun. The ingredients were tested with all four of the chemicals. They were Lugol’s solution which tested for starch, Benedict’s solution which tested for sugar, Sudan IV which tested for lipids, and Biuret reagent which tested for protein. Each chemical found if that ingredient contained either proteins, lipids, starch, and/or sugar.

We then recorded the initial color. We placed each tube in boiling water for one minute and recorded the color results and gave our conclusion. To test for starch using Lugol’s solution, we reused the test tubes and added a squirt of the solution. We recorded the final color and then our conclusion for each content. To test for lipids using paper towels, we placed a drop of solution and we let it stand for one minute. We then recorded our observation, if it was dry or not dry and wrote our conclusion for each sample. To test for proteins using Biuret’s reagent, we added a squirt of stock solution plus a few drops of Biuret’s solution. We wrote the initial color. We then shook the solution and waited for two minutes before recording the results. After the two minutes, we wrote the final color and conclusion for each content. For the unknowns, we wrote the odor and appearance of each content and then tested the benedict’s, starch, lipid, and protein test and wrote our conclusion.

Materials: Substances A, B, C (water), D, 1 test tube of water, unknown plastic, Tweezers, test tube rack

In order to perform this lab, the students will require a measuring tape and calculator.
