Review: Does Chewing Gum For A Long Time Effect Its Mass?

When we measured the mass of the gummy bear after it was taken out of the water, the mass was much larger than the original gummy bear. To find the change in mass, you subtract the original mass from the mass of the submerged gummy bear. The original mass is 2 grams, and the new mass is 9.4 grams. So, 9.4 grams-2 grams=7.4 grams.So, the change in mass is 7.4

First, each table received 2 gummy bears. Each gummy bear was measured for their height, width, and thickness in mm. Secondly, 150 ml of water was poured into a cup with your group number on it. Then after we recorded our measurements of the gummy bears, one gummy bear (A) was placed in the 150ml cup of water, while the other gummy bear (B) was placed in the Ziploc bag. The gummy bears were measured again after 24 hours. When we checked the gummy bears after 24 hours, gummy bear B in the bag stayed the same, while the height and width of the gummy bear A in the water grew and the thickness shrunk. Originally, the gummy bear A in the water weighed 2.57 grams, measured 12mm thick, 10mm wide and 17 mm tall. After the experiment, gummy bear A

Problem question: Our problem question was, “How does the amount of time chewing affect the mass of the bubblegum?”

In this lab the density of a glass marble was measured. Since the formula for density is mass divided by volume, the the mass of the glass marble alone was measured using an electronic balance. Afterwards, the volume of the marble was measured using the displacement water method. 20 mL of water was added to a 25 mL graduated cylinder and the amount added with correct precision and uncertainty was recorded. Once that step was complete, the graduated cylinder with 20 mL of water was slightly tilted so that the glass marble could be placed inside. The new volume was then recorded with correct precision and uncertainty. Then, the original volume was subtracted from the final volume to calculate the volume of the glass marble with the correct amount

12. Place the magnet on the scale to measure the mass of the object. Record the mass in Data Table 5.

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

Repeat the above step by adding 3 pennies at a time (zeroing the scale at each interval) until you have recorded the mass of 15 pennies.

Using “Step 2”, as outlined in the Background, determine the percent difference for each food. Record the percent difference in Data Table 2.

Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours

Seven various household objects were chosen to measure using a digital gram scale. Each object’s mass was estimated by lab students and recorded in data table 4. A quarter, ball point pen, rubber bulb, large paper clip, green crayon, house key and a copper penny masses were estimated and recorded in data table 4. Each object was placed on the scale individually and its actual measurement was recorded in data table 4. As we started estimating the household objects we were often not correct in our estimations. As we measured more and more objects, we got better in our estimations by comparing objects with known masses and comparing them with the unknown

Step 2: Obtain approximately .25 grams of Aluminum Foil and make observations of the foil. Record the exact mass in your data table.

Chewing gum can help increase alertness and attention. In one study, chewing gum was an A+ advantage. People performed better on verbal and math problems and were about 10 percent more alert when they chopped away. Other research suggests chewing gum can boost brainpower in people of all ages. Middle-school gum chewers received higher grades in math compared to the non-chewers. Gum chewing affects standardized math scores in adolescents. A stick of 5 chewing gum may even be helpful during a long day at the office, since chewing mint or caffeinated gum can decrease sleepiness. A boost of happiness may be found inside the wrapper, too. A stick of gum has proved to increase heart rate and cortisol levels, which sometimes results a better mood. Another study found two week of gum chewing decreased participants anxiety and some symptoms of depression. There may not be a definitive reason for chewing gum magical mental enhancements. Lucky for teeth, the answer isn’t the sugar since scientists have experimented with sugar-filled and sugar-free gum. Some experts

Certain companied that make gum are Trident, 5 gum, Juicy fruit, Extra, Orbit, Eclipse, and many more

This purpose of this experiment is to calculate the thickness of a sheet of aluminum foil. This experiment is necessary because the human eye cannot accurately measure the small thickness of aluminum foil with only a ruler. However, to understand the procedure one needs to understand conversion, density, and volume. Conversion is when one converts one unit to another unit using a conversion factor(e.g. 2.54cm/in). Density is how much mass there is in a certain volume(density=mass/volume) and it stays constant in a substances and mixtures that have the same composition. Volume is the amount of space that an object occupies. The experiment will consist of weighing of aluminum foil, measuring the length and width, then converting these values

Materials and Methods: Using all PPE a weighing boat and a balance were used to measure out 1.1121g of pieces of aluminum can.
