The sugar used in this experiment was created by mixing ten milliliters of starch,glucose, and regular countertop sugar. This was transferred into the joint water bottle tunnel using a funnel. Both ends of the tunnel were sealed shut and each measurements were taken every three minutes and final measurements were taken after 21 minutes. The results were
In this lab, we soaked a gummy bear in water for twenty four hours to see the effects osmosis would have on it. When we got our gummy bear we would take its measurements and soak it in water. After twenty four hours we would take it out and record the measurements again and find the percent change. The question that we addressed in this lab was, what would happen if you soaked a gummy bear in water for twenty four hours? I hypothesized that after this time the gummy bear would increase in size.
We are doing a gummy bear lab. Gummy bears come in different sizes, shapes, and colors. Gummy bears are squishy, chewy, and sticky, they are made of sugar which are glucose and glucose are carbohydrate. We predict that during this stage of lab the solute and solvent will go through the stages of hypertonic, hypotonic and isotonic. We get 4 gummy bears and 4 cups filled half way with different types of liquid, such as Salt-Water, Coffee-Creamer, Vinegar, and Soda.
I’m going to talk about other researcher experiment on “How long would it take to get to the center of the Tootsie Roll Pop”. Also my point of view on what I think about their say on their experiment about “How long would it take to get to the center of the Tootsie Roll Pop”. On the Tootsie Roll web page they had three scientific studies that have attempted to determined on how many licks it take to get to the center of the Tootsie Roll Pop. The first one is from a Purdue University where a “A group of engineering students from Purdue University reported that its licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. Twenty of the group's volunteers assumed the licking challenge-unassisted by machinery-and averaged 252 licks each to the center”.
I never realized how gross wild strawberry and tangy citrus flavored Trident® Layers TM chewing gum tasted after 15 minutes. 58.6% of the mass of my sugar free piece of gum was lost after the experiment. Because the company had claimed that the gum contains no sugar, a type of sweetener must have been added instead. The flavor created by the sweeteners faded as the gum was chewed for a longer time. The sweetener had been absorbed and on its way to be digested little at a time.
During the experiment, observations were made of their color, mass, height, and width. This data shows percent mass change of the gummy bear and how the gummy bear was affected by the salt water. It also displays how the height and the width of the gummy bear changed because of the salt water, which made the gummy bear more compact. The more salt that was added to the distilled water, the more compact it was, however, if there was not a lot of salt in the mixture, it became large and fragile. The mass of the gummy bear was increased as a result of less salt being added with the distilled water.
A good example of how someone could turned out if they were abandoned perhaps, the monster from the book Frankenstein-Chapter 5. He was abandoned by his creator and left to fend for himself, he was never taught anything and later on in his life he began to murder the family members of his creator in hopes of torturing him. If he were to have been cared for by Victor the monster could have had an easier time applying himself to the outside world.
Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with
Next, weigh out 5 grams of sugar and 1 gram of yeast. Once in proportions, add it to test tube A. Thoroughly mix around the sugar, yeast, and tap water. You can do this by shaking the test tube gently. Make sure you do not turn it upside down. Then, cover the top of the test tube with a balloon and gently place it into a 400mL beaker filled up about half way (about 250mL) with water.
The ICEHOTEL does a very good job of effectuation, the idea building ventures by using techniques of non-predictive control, seeing the future as fundamentally unknowable as it’s filled with surprise after surprise. On one hand, the simplicity of the idea as not a lot of technology was involved in this venture and on the other and the improbability of anyone building a new venture which is an igloo in the Arctic Circle. The overall idea, but also to grow it which eventually grows into partnership with Richard Branson shows how improbable it really is. Entrepreneurs start ventures based on the skills and people they know.
Only the heated solution caused the balloon to expand, suggesting that the increase in temperature is linked to the balloon’s expansion. Furthermore, as the solution was only heated to 60°C, no water vapor was produced to fill the balloon, suggesting the gas was produced solely by the yeast. Thus, the yeast reacted to the heat, supporting the claim that yeast can respond and is alive. Sources of error in this experiment could have included incorrect preparation of solutions. The solutions of yeast, water, and sugar, could have been measured incorrectly causing the control and experimental solutions to be different.
Bears with thicker coats have a higher survival rate A population will change over time. Survial rate of bears with thicker coats rises, population of bears with thin coats will gradually decrease 3. In ostriches, there are 2 types: ones that run fast and those that run slowly.
Two of the same types of plants were used, in order for the results to be reliable. One of the plants was labelled DISTILLED whereas the other was ACIDIC, so the results don’t get mixed. The DISTILLED plant was used as a controlled variable, where normal spring water was used (pH 7.3) The ACIDIC plant was the one the experiment had taken place on, this was where lemon water was used (pH 2.0) Throughout the experiment pictures were taken, so one will be able to notice the colour change on the acidic plants, as it had started to slowly die. With both plants you are able to notice that they had both started to grow flowers, but more the spring watered plant than that on the lemon juice watered one. The results of the plant growth was recorded to we would be able to notice the amount it had grown, this would be the water compared to lemon juice.
They gobbled down the marshmallow immediately. The rest struggled hard to resist eating it. They covered their eyes, talked to themselves, sang, played games, even tried to go to sleep. The preschoolers who were able to wait were rewarded with two marshmallows when the researcher returned.
The thinner the container the slower the reaction as there are less particles which the substances can collide with. Use the same sized container for every experiment
