The balance of an object mainly involves the dissemination of mass in the object. In a myriad of aspects, balancing yourself or an object can be extremely different especially when we all odds such as gravity is stacked against you. As an example, some teenagers find it hard to balance school, sports and a job. With so much stress and various loads of duties it becomes too heavy for them to handle, and without the right balancing techniques, they can certainly tip over and fall. The same idea applies to the human body and objects in different situations. You find it surprisingly easy walking on the edge of a curb with a heavy backpack in front of you and at the same notion, find it hard for you to walk on the edge of the curb with the backpack …show more content…
The independent variable of this experiment was the placement of the marshmallows and the amount of marshmallows used. The dependent variable was balance of the structure. The methods used to go through with this experiment was quite simple. First, on a skewer, I placed one marshmallow in the middle and one on each end. Second, I placed the tip of my finger under the middle marshmallow and tried to balance the structure on your finger. This was the starting point for building all the other structures. Once I could balance the basic structure, I poked a toothpick pointing up into the top of the marshmallow in the center of the skewer. After, I added one marshmallow on top of the toothpick and push it down until it touches the marshmallow in the middle of the original structure. Next, I made another basic structure and poked a toothpick into each end marshmallow. I added one marshmallow to the end of each of the toothpicks and connect the marshmallows with a skewer so I got a rectangular shape. Then I placed the tip of my finger under the original balance point and try to balance this structure on my finger. Once I could balance it, I determined the center of mass of your structure. I added a toothpick to the top of the marshmallow in the center of the original skewer and poked the toothpick in, pointing up, and push a marshmallow down on it. Next, I placed the tip of my finger under the original balance point. I saw if it balanced or not, and once it did I added one more marshmallow to the toothpick and repeated previous step. After, I started with another basic structure and this time, I poked a skewer into the bottom of each marshmallow on the ends of the first skewer. I connected the two skewers together with a marshmallow, which resulted into a triangular structure. Once again, I placed the tip of my finger under the original balance point and tried to balance the
The name of the lab is “Drops on a Penny.” I was expected to find the independant variable, dependant variable, write a hypothesis, and test the experiment. After testing the experiment multiple times, I needed to find the average amount of drops for each trial, graph them, and tell what kind of relationship it is. The last thing I needed to do was rewrite the details of the project and write a conclusion. The point of the experiment was to have the students get used to the idea of a lab, and get familiar with independent and dependent variables.
Data Analysis Does the mass of a pinewood derby car affect the speed? If the mass of a pinewood derby car affects speed then the more mass the car has, the faster it will go. The procedures for the experiment were; Go get a pinewood derby track, car, scotch tape, quarters, and a timer. Set up the track. Make the derby car with the instructions included with the kit.
In this experiment, we devided each of the different beans. We used mug, black, and coffee beans. By placeing a plate for each bean, We where able dividing each the mug, black, and coffee beans into each plate. After dividing each bean we labled the name and group so we can better understand the difrence between the beans. The meathod of division is very simple and organized, alows to diffrentiate the difrence between each bean.
Anth. 105 Human Species – Lab 3 Report Sirin Gul November 11, 2017 Introduction In Lab 3, we examined the relationships between diet quality, tooth shape and daily travel distance. Evolution has changed how humans and other primates live and survived according to their environment. They are relatively related/similar to each other when it comes to fossil hominins, humans and other primates.
Identify the independent Variable Size of the tablet Identify the dependent Variable Reaction time List the controlled variables The solution (water), temperature, volume of water (200 mls) The amount of Alka- Seltzer How will the dependent variables be measured A stop watch will be started as the pieces of Alka-Seltzer are dropped into 200ml of room temperture water Describe the expected results if the hypothesis is true The 3 smaller pieces of Alka Seltzer will dissolve quicker than the ½ tablet .
In 1980 Candy Lightner was a woman who stood up against drunk driving by creating a club called MADD (mothers against drunk driving). According to their website (madd.org) their mission is “To end drunk driving, help fight drugged driving, support victims of these violent crimes, and prevent underage drinking.” MADD’s goal is for there to be no more victims in the entire United States. That would save thousands of lives that are killed each year from drunk driving.
Catapult Assignment How it worked: My catapult functioned by using built up tension in the 2 vertical popsicle sticks and the elastic band wrapped around the 2 popsicle sticks. The forward momentum is created by using the potential energy in the popsicle sticks and the elastic band; so when it is released, all the potential energy, becomes mechanical energy. My catapult is a slingshot style design.
Through the ins and outs of this experiment, the goal was to see if hanging a chicken feeder on a hook decreased the amount of chicken feed that was consumed by birds. The question that was asked was “If a chicken feeder is hung off of a hook, then will the amount of chicken feed eaten by wild birds decrease?”, and the hypothesis is “if a chicken feeder is hung off of a hook then the amount of chicken feed eaten by wild birds decrease”. There were numerous variables and trials that had to take place for the experiment to perform as desired. The control group was the feeder that was at ground level, and this portion of the trial was tested seven times. The experimental group was the feeder that was not at ground level, but on a hook.
The marshmallow test is a test for kids that are about 4 to 5 years old. The test is to see if the kids don 't eat the marshmallow. There put into a room for 15 minutes with the marshmallow in front of them. If they do not eat the marshmallow to get another one,but if they eat the marshmallow the kid fails. About 15 years later the kids that did not eat it were successful and they had good grades but the kids who ate it,were not so successful and got bad grades.
In this lab there were five different stations. For the first station we had to determine an unknown mass and the percent difference. To find the unknown mass we set up the equation Fleft*dleft = Fright*dright. We then substituted in the values (26.05 N * 41cm = 34cm * x N) and solved for Fright to get (320.5g). To determine the percent difference we used the formula Abs[((Value 1 - Value 2) / average of 1 & 2) * 100], substituted the values (Abs[((320.5 - 315.8) /
In the Penny Boat Lab, we made a boat to hold pennies in water. First, we collected materials we needed which were scissors, a ruler, water, pennies, aluminum foil, a triple beam balance and a container. Using the ruler, we measured the foil 15cm by 15cm, then cut excess pieces. Next, we had to fold the foil into a “boat”. After, we measured the mass of our boat using the triple beam balance.
Balance in art and in other subjects has a few different, indirect meanings but one meaning that could ultimately unify the word is that it allows something to remain in a steady position. In art, balance can generally be symmetrical or asymmetrical. Symmetrical balance is easy to view because both sides of the work can be considered the same; if one were to “fold” the piece then it would match perfectly because one side of the piece is the same as the other side of the piece. For example, the white house and The Holy Place all depict symmetrical balances. Meanwhile, asymmetrical balances are a bit more difficult to comprehend because many people tend to have issues with interchangeably thinking balance means symmetric.
In the experiment each preschooler was put in a private room by themselves and a marshmallow was put on a table before them. All distractions in the room were removed so the only thing the child would be focusing on would be the marshmallow. The child was then given the options of
The Effect of Sugar Concentration on CO2 Production by Cellular Respiration in Yeast Introduction In this lab, our main focus was to find how sugar concentration affect yeast respiration rates. This was to simulate the process of cellular respiration. Cellular respiration is the process that cells use to transfer energy from the organic molecules in food to ATP (Adenosine Tri-Phosphate). Glucose, CO2, and yeast (used as a catalyst in this experiment) are a few of the many vital components that contribute to cellular respiration.
