By reading the new volume of the liquid substance amount one will then subtract the initial milliliter amount from the final volume reading, thus giving you the volume of the rock sample. Using the mass of the sample rock obtained one will then divide the final volume reading unveiling the density of the
Its outer boundary is around 2,890km beneath the earth’s surface. 3. The Mantle: The mantle is the layer between the crust and the outer core, which is the broadest section of the Earth. It has a wideness of roughly 2,900.
To find the density of the three coins, I followed a short and simple procedure. First, I used the triple beam balance to find the mass of each coin to the nearest tenth of a gram. Next, I filled the graduated cylinder with 50 mL of water. Then I put the quarter in the graduated cylinder. In my data table, I recorded the volume of the quarter and the the water in the graduated cylinder.
On our paper we predicted the amount of pennies that could fit in the boat before it sank. We tested the boat in the water and added pennies one by one. We then calculated the mass of pennies that fit in the boat and the density of it. The purpose of this Lab was to make a boat that holds as many pennies as possible and understand how to calculate
This would be the ideal place to analyze the natural formation of earth. Moody
During the experiment, observations were made of their color, mass, height, and width. This data shows percent mass change of the gummy bear and how the gummy bear was affected by the salt water. It also displays how the height and the width of the gummy bear changed because of the salt water, which made the gummy bear more compact. The more salt that was added to the distilled water, the more compact it was, however, if there was not a lot of salt in the mixture, it became large and fragile. The mass of the gummy bear was increased as a result of less salt being added with the distilled water.
It cannot be denied that our indigenous population has suffered severely since the colonisation of Australia. While the movement towards reconciliation is undoubtedly gaining widespread support, unfortunately many misconceptions are still prevalent and the future of many indigenous Australians is still uncertain. Disadvantage is still experienced by an unacceptable number of the population. Statistically, indigenous people have poorer health, opportunities for education, life expectancy, employment options and the majority live in the remote areas of Australia. As well as this
Observations Variable Observations Size of “rock” Trial #1 Trial #2 Trial #3 Small (Dropped from 30cm) Marble fell near the surface.
We will have the demonstrations of the simple machines. The students will go to each machine, in a group, and experiment
We only used one material which was the weight in this experiment. The weight had a smooth surface which may have allowed it to slip easily compared to a material that has rougher sides. An object with a smoother surface has less friction and when gravity acts upon it, it will slide easily thus at a lower angle causing a low coefficient. Q5.
Conclusion In conclusion, it can be devised from the previously mentioned information, that the theory of snowball Earth is still surrounded by mystery. Evidence supporting the theory are unable to absolutely assert that the Earth was covered entirely with ice at some time of the geological scale. Moreover, perhaps the name of the theory itself “Snowball Earth” requires rethinking as the Earth was not just a white ball especially with the presence of regular active volcanoes. Thus, continuous effort and farther investigations must take place to solve the mystery of such
There are many things Scientists’ do to figure out what is inside Earth’s layers, two ways scientists’ use to find what is inside Earth’s layers are studying meteorites and using direct observation. When studying meteorites Scientists’ use what the meteorites are made of to figure out what Earth’s layers are made of. Meteorites are all made of different materials that tell Scientists’ what’s inside Earth’s layers. Some meteorites are stony and are “rich in olivine and pyroxene.”
The Expanding Earth is explained by the fact that the planet could gradually grow larger. According to Nikola Tesla, a scientist, compared the process to the expansion of the Earth to a dying star. The Expanding Earth hypothesis has never been proven wrong, but it has been widely proved with many other theories. Throughout this research paper explains how professors of geology and scientists examine the supporting evidence of how the Earth has been constantly unchanged for thousands of years. The Expanding Earth theory is the reason why the Earth has expanded.
In this experiment, the amount of water lost in the 0.99 gram sample of hydrated salt was 0.35 grams, meaning that 35.4% of the salt’s mass was water. The unknown salt’s percent water is closest to that of Copper (II) Sulfate Pentahydrate, or CuSO4 ⋅ 5H2O. The percent error from the accepted percent water in CuSO4 ⋅ 5H2O is 1.67%, since the calculated value came out to be 0.6 less than the accepted value of 36.0%.This lab may have had some issues or sources of error, including the possibility of insufficient heating, meaning that some water may not have evaporated, that the scale was uncalibrated, or that the evaporating dish was still hot while being measured. This would have resulted in convection currents pushing up on the plate and making it seem lighter by lifting it up
The core is the innermost part of the Earth, approximately 3000 kilometers or 1864 miles below the surface, made up of an iron-nickel alloy, which becomes a solid at the very center due to the enormous
