The Penny Lab Hypothesis

In my experiment, I compared if the side of a penny affected how many drops of water it can hold. I took 2 pennies, one on the head and one on the tails. I took a dropper and filled it with water. I then dropped the water onto the penny and counted how many drops of water it could hold until the water went on the paper towel. My hypothesis was that the tail side of the penny could hold more water, and it did. According to my data, the tail side average was about 1 whole drop away from the head average. This means that the tail side could hold more water. The exact average of the head side on the penny was 23 drops. The average of the tail side of the penny is 24.72727273 drops. That was super close. Although I made sure my hand was the same

In 2011, it cost 2.4 cents to produce the penny. The penny was first minted in 1857. It cost 2.4 cents to make the penny. Also the United States loses 1.8 cents for every penny being made. In conclusion we should get rid of the penny. The United States should get rid of the penny because it is people are not using them, cost to much, and other countries have already dropped the penny.

Describe the experimental method, state its advantages and disadvantages, and distinguish between independent and dependent variables.

Money is crucial in many ways or everyday events like for buying food, paying rent, etc. Money has its own value but not all currency is used. Money has its own value but not all currency is used. The penny has the least amount of currency and is found on the sidewalk, sofa, in between car seats because nobody benefits form the penny. It doesn't have enough value to be kept around so lets just end the penny ones and for all.

The penny should be removed from the United States department of treasury. The worthless one cent coin is useless in today's economy, and in people's everyday life. The penny has been around for many years going back to 1787, and throughout the years prices increase, and the value of the penny decreases. So why waste money on producing these "unnecessary" coins?

There also will be an agreement where if the subject feels uncomfortable with the experiment he or she is free to stop and leave. If I was to conduct this experiment then my hypothesis would be if that a person can read 15 cards straight in a row consecutively then the person ESP abilities. If the person cannot then he or she does not have ESP abilities. In this experiment the cards would be the independent variable and the dependent variable will be the person's ability to read the cards. An independent variable is the variable that is change or controls in a scientific experiment in order to see the effects of being tested for the dependent variable; which, the dependent variable is the variable being tested and measured inside experiment. In order to make this experiment more experimental than correlational research, scientists would isolate and manipulate only the independent variable and observe its effect on the dependent variable in order to establish a cause and

The independent variable in this situation is the color of the paper given. The experimental group of 12 year old students is the group being administered the yellow colored paper. The results from this is going to be compared to the control group of 12 year olds who are going to be taking the same math test

Based on the experiment of ‘The Value of a Penny: Mass Lab”’, it is seen from the data table and believed that 1982 was the year that the penny started to devalue. The prediction of the year 1968, had a percent error of 0.71%(when rounded to the nearest hundredth). It is seen from the data that starting from 1960 to 1981, the mass of the penny was around 3.1 and 3.2 grams which shows it remained similarly constant. Then, after the decrease of 0.6 grams from 1981 to 1982, the range from 1982 to 1997 stayed at around 2.5 and 2.6 grams. This supports the claim because it shows how much the mass of the penny has altered over the course of almost around 40 years. After doing research, https://www.usmint.gov stated that before 1982 a penny was composed

Received a call from Krystal reporting that her penny hopper constantly experienced pick failure. From Trainer provided picture, there is something interfering with dispensing disc movement and actually caused some damage this component. Trainer reported that she and a WM assistance manager were not able to rotate this disc in any direction at all.

Like every other science project, mine starts with a question. How does bridge structure affect the weight bearing capacity? is the question. If I change the bridge structure on the most popular bridges, then those specific bridges will be capable of holding longer and hold larger amounts of weight. is the hypothesis. The three types of variables used are independent, dependent, and control variables. These variables include the location of the bridge, the bucket, the amount of water, the supplies, and the climate I experiment in.

* In every experiment there are variables that affect the way an experiment will go. The three types of variables that are measured are Independent, Dependent, and Controllable variables. In my experiment the Independent variable is the three different models of paper airplanes that I have chosen to make and experiment with. The Dependent variable includes the distance the paper airplane goes. The Controlled variable is me making sure that I throw the paper airplanes from the same starting point a well as the same weather conditions. The controlled variable is the one that cannot be changed because it would affect the other two variables. In this case I threw them in my house since I have a very long hallway that leads into the front family room and there is no furniture that would interfere with the results.

The control date remained the same throughout the experiment. Each indicator bead stayed at “5” on the UV color guide. The experimental data varied. The beads that were under the sweatshirt and the t-shirt fabric had a “2” on the UV color guide, while the hat fabric had a “1.” First, I said that the sweatshirt fabric would make the bead have the lowest number on the UV color guide. I was wrong because the sweatshirt fabric scored a “2.” Next, my hypothesis said that the t-shirt fabric would cause the bead to have a darker color than the sweatshirt fabric. That was incorrect because the t-shirt also scored a “2,” just like the sweatshirt.

European Pennyroyal, Latin name Mentha Pulegium, has been a prized medicinal herb since Classical times. The plant is also known by the common names Lurk-in-the-ditch, Pudding Grass, Squawmint, and Mosquito Plant. American pennyroyal is a related plant, known in Latin as Hedeoma Pulegoides. It is a low-growing plant in the mint family with highly aromatic leaves, and whorls of pinkish-white flowers on square stems.

The experimental hypothesis of this experiment is that people would perform better at work with faster music as opposed to slower music. The independent variable for this experiment would be the speed of music, while the dependent variable in this experiment would be the performance of the two secretarial pools depending on the type of music the pools listened to. Since the experiment’s purpose was to find if fast music truly enhances people's work performance, the experimental group is the group expected to work with fast music. In which case, the control group would be the pool expected to work with slow music. The control group used for the experiment was not appropriate, because there should have been one group who were asked to work without
