Which reaction took the least amount of time in the…
While placing the paper towel down onto the water, the amount of force I used varied for each trial. To combat this, a mechanism that applies equal force down onto the paper towel each time could have been used. That Brand #4 and Brand #2’s lines on the graph are rather erratic indicates that these known sources of error may have affected the…
Basically deviation produces a negative response to counteract or nullify the deviation. it is a 'feeding back' of the disturbance to the status quo. due to the liver being part of the digestive system, as we know when blood glucose levels fall, the liver glycogen is converted into glucose in order to top up those crucial energy levels in cells. this is an example of a negative feedback…
Another source of error could have been that since the experimentation was over a two day timeframe, one group could have used two different bubble bottles to create their bubble populations. For example, the first soap bubble group tested was the one without help and this population of bubbles survived at least ten to twenty seconds after hitting the ground, but the next day, a different bottle was used and when doing experimentation for the bubble population with help, the bubbles had a tendency to pop immediately upon hitting the ground, which would have made it appear as though the populations without help did survived longer than the populations with help because two different bubble bottles were…
Throughout the text ‘The Wave’ written by Todd Strasser, displays power as a recurring theme. For instance, Laurie Saunders publishes a school newsletter about the cons of The Wave, and shows various different stories from numerous students. Previous Wave member, David Collins gets stuck in The Waves power as he physically abuses his girlfriend, Laurie Saunders for going against what he believed…
In the experiment, I tested how soapy water would affect the amount of droplets the penny can hold. The results of my experiment show that the penny holds less droplets of soap water. When the soap is added to the water, the soap collides with water breaking down the tension. As a result, it harder for the droplets to hold together. To find whether my hypothesis was right, I did several of trials to figure out whether my hypothesis was correct.…
The experiment that I will be conducting focuses on how fast one tablet of Alka seltzer can dissolve in various temperatures of water. The core of this procedure is to determine the impact that temperature has on how fast something dissolves. My hypothesis for this experiment would be that the Alka Seltzer that dissolves the fastest would be the one that was placed in the water with the highest temperature. There will be controlled and manipulated variables explained throughout the experiment. The two main things used in this experiment will be the solute and the solvent, which is Alka Seltzer and water.…
Under the Wave off Kanagawa, also known as “The Great Wave”, is one of the most famous pieces of art in the world; and questionably the most well-known work of Japanese art. The print displays the inspiration of Dutch art, and demonstrated to be inspiring for many artists working in Europe around the nineteenth century. It is part of a sequence of prints called “Thirty-six views of Mount Fuji”, which Hokusai created between 1830 and 1833. It is a multicolored woodblock print, prepared with ink and color on paper that was roughly 10 x 14 inches. “Ukiyo-e” is the term for Japanese woodblock prints created during the Edo Period.…
Cause Scientists don’t know for sure how rogue waves form, but they have some theories. Tsunamis on the other hand, are caused by earthquakes, landslides, and volcanoes. Tsunamis mostly occur in the Ring of Fire. The Ring of Fire is in the Pacific ocean.…
The average absorbance rate in figure 2 presents the different levels of reaction in terms of the chemical compounds. Comparing the average values (Team 1 representing our results) there is not much of a pattern when viewing the absorbance for each specific test tube for each team. Although, there are some values that were around the same range including test tube 2. As for enzyme change, the high amount of enzymes increases the absorbance that shows an increase in reaction as seen in test tube 4 (figure 1). However, because of the decrease at 30 minutes the results take a shift.…
HYPOTHESIS: As the ice cubes melt in the warm water, the melted water from the ice should flow towards the bottom of the cup because the melted colder water is denser than the surrounding water. PURPOSE: The purpose of this experiment is to improve my ability to observe an experiment. In addition, it will help aid me in making proper observations while also drawing conclusions. RAW MATERIALS:…
GRAVITATIONAL WAVES, HOW CLOSE ARE WE? PHSCS 222 Collective Paper November 23, 1999 #123 #272 #666 #895 The Detection of Gravitational Waves, How Close Are We? Since the realization that the general theory of relativity predicts gravitational waves, there have been attempts to actually detect these waves. Indirect observations have been made that support their existence but no direct measurement.…
Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx.…
PURPOSE/QUESTION The question that we will answer using this laboratory report is, “How is the rate of dissolving sugar affected by changing the temperature of the water, changing the rate of stirring, and changing the size of the crystal?” The independent variable of each laboratory experiment is different, however they are all being changed to get consistent and effective results for one dependent variable. The three independent variables are the temperature of water, rate of stirring and size of the crystal and the dependent variable of the all the experiments is the rate of sugar dissolving. HYPOTHESES Below are the laboratory experiment hypotheses that we have formed as a group to figure out what will happen to the rate of dissolving under…
A wave is a disturbance of energy. Sound and light are both disturbances in energy, and they both travel in the forms of waves. While sound travels in a longitudinal wave, light travels through a transverse wave. From a perspective of a human, sound and light on earth is very different compared to sound and light in space. These waves have differences in speed, form, shape, and other properties.…
