The Effect of Osmosis on Gummy Bears In this lab, we will examine the effect of the process of Osmosis on gummy bears placed in 5 different solutions. In living things, the cell membrane is what controls the output and input of the cell. In addition, it is selectively permeable, meaning it can differentiate molecules regardless of size. In non-living things, however, it is semi-permeable, meaning it allows certain substances to enter and exit the object without being able to identify it.
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.
Unknown Lab Report Unknown # 25 By: Jenna Riordan March 19, 2018 Bio 2843 1. Introduction Microbiology is the study of microorganisms found in all different environments throughout Earth, from the hot thermal vents at the bottom of the ocean to the ice at the top of a mountain.
The objective of this experiment was to determine the identity of three unknowns existing in a 1:1:1 mixture. An extraction technique was therefore used to identify the unknown acid, base, and neutral as the compounds must first be separated. Extraction is a method of separation that is based on the difference in solubility of each compound in a mixture. There are a couple of necessary requirements for an extraction to be completed with experimental success. In this extraction there were two liquid solvents used, an original solvent (So), and an extraction solvent (Sx).
The experiment overall was nicely conducted, and results were found through the information gathered. The dependent variable was established very quickly; furthermore, we can find the dependent variable was whether the athletes played a contact sport or a sport like baseball, where most concussions come from being hit by the ball. The independent variable is the number of concussions the test subjects obtained. Ultimately they could not control how many concussions each individual obtained but they controlled which individuals were chosen and what test were ran. The results that ran throughout the whole experiment was an overall success, the results show that multiple compared to single occurring concussions do not have an effect on P3 suppression.
The purpose of this experiment was to discover how the flexibility of a hockey stick impacts the distance and velocity at which the puck will travel. If the puck traveled the farthest distance and maintained the greatest velocity then, the puck was launched by the stick with the most flexibility because it was able to generate more force to launch the puck. However, when testing out just the flexibility of the stick alone, it was puzzling to find that the Bauer Vapor x60 Composite Stick was capable of firing the puck a greater distance and at a greater velocity than the Easton 53 Composite Stick. There had to be another factor that was being missed. It was determined that the flexibility of a hockey stick is not the only factor that impacts the distance and velocity of the puck.
So, in the end, one could conclude that using an aluminum bat is better than using a wood bat, simply because of all the recent advancements in science, metal, and engineering. To develop a science experiment of one’s own they would need a baseball field, baseball bats one wood, another aluminum (same length and weight) a bucket of baseballs, a stake to mark where the baseballs land, 7 tape measures (50ft), a pitching machine, a paper pad and pen, an outfielder, a pitcher, and lastly a hitter. The way one would conduct this experiment is by having the pitcher set the pitching machine to a reasonable speed, then have the pitching machine pitch, the hitter hit 15 balls with both bats. After every hit ball have the outfielder put stakes in the ground to mark where the balls landed, then record the distance after with the tape
The first chapter from the book From my bandage to my Freedom By Frederick Douglass, goes into detail of how Douglass come to be a free person. The story takes place in during the civil rights era. The story go into detail of how when douglas was child being a slave his mistress sought out for him to read just like her son should. However this is immediately shot down from her husband saying that she could not do this. Back then it was illegal for salve to know how to read and write.
How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball?
My question looks at how gravity, and the weight and size of different balls affects how long it takes to hit the ground. The balls I choose was the American football, golf ball, baseball, and tennis ball. As learned in this experiment, weight and size affect how fast the ball drop because gravity will cause the heavy ball to drop faster. This means that the heavier ball should fall faster, while the lighter ball should fall slower. I choose this topic because I want to know if ball sizes influence how fast the ball will hit the ground.
Conversely, the lecturer takes the view that some af those balls should have been broken or some damaging should have be seen on those providing that those have been used for hunting or fighting purpose. Whereas, no damage effect is found on stone balls ' surface.
In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
Well you can find out by reading the rest of this paper. “Where does a basketball bounce best. ”Why do different surfaces affect how high a basketball bounces? Different surfaces affect how high a basketball bounces because different types of surfaces absorb more energy than others.
Physics Applied to Soccer Soccer. The most popular game in the world, and yet the most beautiful. This sport is known for its skill and its way of bringing people together. Though what most don’t know is that a great amount of physics can be applied to the game of futbol. From Newton’s Laws of Motion, to things such as friction and inertia, there is so much to learn from this sport.
The Realist Prescriptions of Carr & Waltz The international system of world politics is constantly filled with political conflict, war, and instances in which cooperation between states seems to be a viable option. This constant cycle between war and peace is representative of the ever-changing environment of international structure. Political philosophers and theorists attempt to understand this cycle by producing theories like that of liberalism, constructionism, and realism in order to better understand and compartmentalize the ever changing environment in order to better understand and deal with the issues that arise between states in the international structure. These theories are influenced by the realities in which these theorists
