surface area vs rate of time Introduction: In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches.…
Get on Board! The book Sugar in the Blood by Andrea Stuart, describes the genealogical research about the Ashby Family. Her research on the Ashby family begins with the journey of George Ashby, who sailed from England to Barbados. In Barbados, he would struggle to make a living. George Ashby like many other immigrants did not know how to work the land.…

In this unit of my 9th grade Physical Science, we are learning and experiencing with labs. In this week's experiment, my class did the paper towel lab. Here, we tested the quality of three different paper towel brands, Viva, Up&Up, and Bounty. Each lab group was testing for a certain quality of each brand, such as strength and absorbency. Through different experiments, each lab group came to the conclusion that one paper towel brand had more strength or better absorbency than the other two.…
CONCLUSION: Two weeks ago, Soundings XVI performed Lab Experiment Number Two. Lab Experiment Number Two was similar to the previous, Lab Experiment Number One. The prompt was to compare the results of pennies dropped in water, versus the result of pennies being dropped into milk, both at 100 mL. The main purpose of this lab was to further discuss more scientific parts of this lab, such as the surface tension when the cylinder was close to overflowing for both the milk and water. Before performing this lab, my group and I created a hypothesis to reflect upon and to state what we believed would dictate the results.…
The purpose of the experiment was to investigate the effect of the different liquids on the gummy bears. We saw how the gummy bears change color, shape, and size. What my hypothesis is that I thought all the gummy bears were all gonna shrink, but what actually happened was all of the gummy bears except for one got bigger. I think everything was fine in the experiment so nothing went wrong. Now that we experienced the experiment, I think I still have some questions like “What will happen if you leave the gummy bear inside the water for like more than one day?”…
Does it Screen? Alexander Hamm Period 2 Ms. Ulrich 11/29 (Graphic that represents the lab) Abstract: My experiment is about testing which brand of sunscreen works best, Equate, Banana Boat, or Coppertone.…
Diffusion Hello today we will be talking about a skittle sure a skittle is delicious but did you know it could be used for many more than just eat. Did you know that you can make an experiment with just a skittle and some water well that’s exactly what we did got a petri dish and filled it up with water then we put the skittle in the middle of the dish. As soon as we placed the skittle in the water it stated dissolving and the water turned orange the skittle got tiny and the top of the skittle got rough.…
We used 5 different sucrose solutions: 0%, 10%, 20%, 30%, and 40%. One group had an ‘Unknown’ sucrose solution, this would give us the opportunity to use all of our data collected from all the groups to figure out what the sucrose percentage would be. We first weighed our eggs at 0 minutes to the nearest 0.1 g and recorded our results. Next, each group put their eggs into mason jars containing the 5 different sucrose concentration levels and 1 unknown. In 15-minute intervals, each group would…
My science fair project involves soda bubbles and temperature. I chose this project because I’m interested in the viscosity(a chemical in soda) that is part of a soda/liquid, and how the viscosity is affected by the temperature of the liquid. I am also interested in bubbles specifically their length of time, so it would be interesting to see how the length of time is affected by temperature. The question that I am going to answer is, how does the temperature of soda affect the length of time of bubbles? The independent variable in the project being done is the temperature.…
We chose to conduct this experiment because both Amber and I are interested in athletics and the science side of it. There have been several researchers studying the effects of caffeine, and they believe it can enhance athletic performance and agility in sports. Because of this we believe if caffeine levels are increased, then time taken to run a lap will decrease when time is a function of caffeine level. To test this we will have a group of ten subject male and female who around the same athletic capabilities. Then, we will give them a set volume of liquid at different caffeine levels to see if the subjects running time changes with the caffeine.…
The purpose of the bath bomb experiment was to examine the fizz by adding extra cornstarch to the bath bomb recipe will affect the overall outcome. If there is more cornstarch added to the bath bomb, then the bath bomb will be less fizzy because cornstarch acts as a dry filler that controls the reaction between baking soda and citric acid. The experiment calls for two different recipes. The first one was the normal recipe which blue was used as the coloring. The other recipe was the extra cornstarch recipe which red was used as the coloring.…
The independent variable in this experiment was time which was 10 minute intervals. The dependent variable was the weight of the raisin before and after each interval. And the control was the water temperature each raisin was placed in, which was Hot, room temperature, and cold. Hypothesis:…
This is because glycerin will prevent the snow from falling rapidly as it is a ‘thick’ fluid. In other words, it has a high viscosity, but water has a low viscosity (low thickness), thus glycerin will thicken the water (changes the water). Therefore, this mixture of liquids inside the beaker decelerates the snow because the gravity is pulling it down. Suggest what the results would be if the hypothesis was supported if the hypothesis was supported, the object will take the longest time to reach the base of the beaker when mixed in the water and glycerin solution.…
The aim of the project is to prove whether or not adding sugar and salt to water will affect the freezing point of the water and will therefor take longer to freeze. Variables Independent Variables: the independent variables are the amount of salt and sugar added to the solution. Dependant Variables: the dependent variable is how long the solution takes to freeze Controlled Variables: the controlled variables are the temperature in the freezer which remains constant and the amount of…
