My action plan for this experiment will be to test three different methods to determine which will be the best at cleaning a rusty penny. I will observe which methods are most successful at cleaning than the others. The method that works best will be determined based on the results of the method with and without salt. According to the research that I have conducted, acid alone does not clean as well as acid and salt, due to the breakdown of copper oxide caused by the vinegar and salt. This will support my hypothesis for this experiment that a rusty penny placed in a solution of vinegar and salt will clean a rusty penny better than placing a rusty peen in cleaning vinegar only. To implement my plan, I will use the necessary materials to
A: The reaction with water and vinegar was the most useful in this experiment. The physical properties were very self explanatory because the texture of the powders was all different expect icing sugar and cornstarch. Also the Ph levels were very similar of six and seven for corn starch and icing sugar respectively. d) Q: How confident do you feel about your identification of the
This experiment was done to test and observe how natural selection works. The Construction Bugs were tested in a flowery meadow to see which colored bugs survive and which do not. Natural Selection occurred because the bugs with odd colors that stood out in the flower meadow did not survive. These were the orange, dark blue, and pink bugs.

If the number of nails increases to 2, than will the amount of paperclips attracted increase? Five trials were conducted using this variable. The measures of central tendency were calculated. The minimum amount of paperclips attracted to the electromagnet was 2. The maximum amount attracted to the electromagnet was 20 paperclips. The mean was 10 paperclips. A range of 18 was noted with the lowest number being 2 and the highest being 20. No mode was observed while the tests were conducted. The median number of paperclips was 8.5.
Stainless steel reamer: It does not rust and it does not give you the funky taste of plastic. So, what you get is pure, citrusy goodness in your juice.
The experiment, focuses on the effects of acidic drinks on teeth. In this experiment, the scientist is trying to answer which liquids; Arnold Palmer, Coffee, Coca Cola, V8 Splash Tropical Blend, and crest pro-health toothpaste, affect your tooth enamel the most. The Independent Variable are four ounces of each liquid, and the dependent variable is the staining of teeth. The Constants are the toothpaste, toothbrush, the amount of time the eggs stay in the liquid, and the type of eggs used. The units used while measuring the effect of liquids on teeth is ounces.
As I do this experiment the thing I am going to be changing is the
The research our experiment was founded on was that carried out by Taylor and Faust (1952). They carried out an experiment on 105 student’s, which was designed in the method of the game ‘twenty questions’. The students were split into teams of one member, two members and four members. They were then told that the experimenter would keep an object in mind whether it is animal vegetable or mineral was also stated, and they were then allowed 20 questions and guesses to reveal the identity of the object. In there experiment they found that the group of two members performed better than the group of four members in terms of how many guesses and questions it took them and how long it took them to deduce the identity of the object. However Taylor and Faust found that the efficiency did not differ in any significant way.
Apple cider vinegar is not used for health reasons but also as cleansing argent whereby it removes bacteria, germs, odor and even stains and spots. It breaks down fat, mucous and phlegm that are in the body. This improves a person’s health and the functions of the liver, bladder and kidneys. Apple vinegar can also be used in place of lemon or lime when call by the recipe.
In the experiment we have a time taker, tapper, and 3 observers. The tank should have a black line straight down the middle of it, however, if the 10 gallon tank does not already have a line down the central part of the tank, take a sharpie and draw one exactly down the middle. Once you acquire the tank make sure there are 8 fish in the tank, if not, position 8 fish in the tank. The first trial that was done required the tapper and the time taker with 3 observers. The tapping began for 10 seconds while the fish behavior was observed by the 3 of us observers. After the 10 seconds the results were verified and discussed among the observers. There was an elimination period for 1 minute, and trial 1 was repeated again for the second time making it trail 2 for 20 seconds. The results were documented once again and discussed. The second trail that was done required a little more focus to assure the tapping and placement was the same as the one before. After 20 seconds the results were recorded. There was a rest period for 1 minutes, and trial 2 was repeated making it trial 3 for 30 seconds. The results were
The second best practice of generating and testing hypothesis occurs in this lesson when students are given the objective of proving if the statement: was the Nile River a gift to the ancient Egyptians accurate. By using this hypothesis, students know what the objective of the lesson is, and what question they must answer in order to prove
I picked the science experiment elephant toothpaste this year, because it seems interesting and fun. It is also a way to test if the removal of oxygen in these experiments will actually work. I have four different experiments. Two out of the four experiments I am testing, is to see if there is a different reaction time and size between yeast and potassium permanganate and the percentage of the hydrogen peroxide. My third and fourth are tests of elephant toothpaste is to see if adding cornstarch has a color reaction to the potassium iodide to make it look like it is “glowing”, or if the yeast and fluorescent dye will make it look “glowing”. I think the elephant toothpaste that uses 50% hydrogen peroxide and potassium permanganate will have the
acid and water to see how it affects the rate of reaction. I will use
Planning and Method. Any experiment needs variations as well as fairness to be a true success. The two variations I will include in this experiment shall be: 1) The number of paperclips on the bottom of the helicopter. 2)
For the purposes of the exploration, volunteers will be labeled, Spectator A, Spectator B, Spectator C, and Spectator D. Throughout this exploration, the coins used will be in CAD. The magician brings $1.96 to a table, consisting of six pennies, six nickels, six dimes, and four quarters. Spectator A is asked to pick up one coin. Spectator B is asked to pick up a different valued coin. This process is repeated for Spectator C and Spectator D. Then, the performer asks Spectator D to pick up coins which adds up to four times the value of the original coin taken. Spectator A is asked to pick up the same value of coins they picked up before. Spectator B is asked to pick up double the value of coins they picked up, and Spectator C is asked to pick up three times the initial value of the coin they were asked to pick up. The magician then turns around and correctly identifies the initial value of the coin picked up by each of the spectators.
