The Mythbusters observed the myth that driving whilst talking on the phone is as dangerous as driving drunk. They formed their hypothesis that driving on the phone is as dangerous as driving drunk. Then, they tested their hypothesis. They created an experiment that would have participants drive a car through a course three times. Each time a participant went through the course, they experience different conditions. The first time, both participants drove through the course normally. This served as the control group for the experiment. The second time, participants were asked questions over the phone while they completed the course, and, the third time, they were drunk when they drove through the course. Throughout the experiment, there were several independent variables in place to ensure that only one variable was being tested.
Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.
The purpose behind the egg drop project is for students to understand the concept of momentum, collision, impulse and force. To do this, they will create a protective carrier that will surround the egg. The egg will then be dropped from a certain height. The device that is created should weigh enough to increase the time of impact, therefore decreasing the force of impact on the egg so it doesn’t crack.
For this project, I made a capsule for an egg that is to be dropped from about twenty feet. This capsule that I made was not what I was thinking at first but when I started to build it, I saw that this capsule would hold better than the one that I was thinking which was a triangular capsule with the egg in the middle but I saw later one that the egg would break if it hit one of the flat sides. The capsule is a cube that is made out of the tongue depressors and I used most of the yarn for the big cage and I used the Elmer’s glue to glue the tongue depressors together. I used pieces of the paper clips to hold the popsicle sticks together with the tongue depressors and some
Next, during the experiment, it was observed that the hole in the lifesaver was not big enough for Sam to go through it. It was also observed that Sam and the lifesaver were both very fragile in the sense that they could be reshaped or stretched easily. In contrast, during the lab, it was observed that to go through with the procedures four paperclips are needed. Further, into the lab, it was noticed that the lifesaver needed to be stretched at least 4 more mm for sam to go through the lifesaver. The hypothesis was proven to be correct because after reshaping the paper clips from their original form it was
6. Fe (NO3)3, Ferric nitrate, is much more active than ferrous. It could be identified by its reddish color and when mixed with thiocyanate, it reveals a “bloody” red color.
Students will carefully observe acts of aggression and prosocial behavior on television, report their observations, and analyze their data to draw conclusions.
So my guess was correct again. The blue water did slowly enter the red water.
C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.
The outcome of the experiment was that the bag exploded when the chemicals mixed together and released off air pressure till the bag exploded. When doing this the experiment and watching the outcome had been surprising. The glycerine didn’t explode like the vinegar did in the first one because those chemicals never mixed. The tissue made the lab last alot longer. It didn’t matter if either the tissue was used to hold the baking soda in place, or the napkin. The results somewhat had matched up with the hypothesis of the bag exploding. On the other hand it was surprising that the lab to so
The Hedwig glass beaker is one of the significant material that designed or made by the Muslim craftsman. The relics were associated with some sort of super natural power because as water touched by St. Hedwig lips it turn into win. On the top of the relic there are a lion, griffin, an eagle, and a tree figures. The first observation that I made on this relic is the design of the figures that seen on the top of the relic was made with sharp lines.
Four eggs that were previously soaked in vinegar were placed into four beakers with different levels of a glucose solution. The four beakers were filled with distilled water, 0.5M glucose, 1.5M glucose and 2.0M glucose. After the eggs were placed in the solutions, they were left for 60 minutes but weighed every 15 minutes to record whether there was an increase or a decrease in mass. The various masses were recorded as well as the percent change in mass. These were then recorded as line graphs. From this it was able to be determined if the egg had been in a hypotonic, hypertonic or isotonic solution, thus being able to determine if osmosis had occurred.
Scientists Heather Bateman and Mélanie Banville tested three sites (non-urban, urban rehabilitated, and urban) for the abundance and diversity of reptiles. The experiment was well designed for many reasons. First, the scientists who performed the experiment provided a lot of reliable data. For example, the data stated that reptile abundance for non-urban habitats was 42 reptiles, urban rehabilitated habitats was 36 reptiles, and urban habitats was 6 reptiles. Also, the experiment contained many types of species. 7 of the 8 species were lizards and one was a snake (Western Diamond-backed Snake). The same 8 species were tested at each site. The combination of reptiles showed the movement of different species and which species are the most sensitive
In biology class, we wondered what evidence we could gather through shell-less eggs so we could show osmosis and diffusion through the egg inner membranes. My hypothesis for the egg in cranberry juice was that the color would change to red. My hypothesis for the egg in La Croix would be that the texture would become rougher and it would become smaller. My hypothesis for the egg in syrup was that the color would become brown and the egg would become larger. I believe with the knowledge I had at the time, that my hypotheses were not convincing because I did not explain why I thought the eggs were going to change, I just stated it. In a controlled experiment, the independent variable is the only variable that can be adjusted, while the dependent
When analyzing the IR spectrum of Ruthenium complex with DMSO, the prominent peak is presented at 1105.54 cm−1. This peak indicates that S=O bonded in DMSO. For DMSO, the frequency is around 1050 cm−1. From our spectra obtained for DMSO where the S=O peak is at 1017.65 cm−1. Since the bond appears at a higher frequency, this shows that the bond is strengthened by the reaction. This indicates that when the copper metal was combined with DMSO, it bonded with the Sulfur atom. Combining ruthenium with sulfur atom caused it to donate a pi electron as a back donation.
