Introduction The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density.
In the distances vs. time graph for slow constant velocity buggy vs. faster constant velocity buggy, both data represent similar linear lines. For instances both buggy start picking up distances at 0.6 seconds and then from there both buggy continue to cover more distance at different pace as time continue. Not onces, did either buggy stop or loses distances which help create the linear line. The differences between the two linear line is that the faster constant velocity buggy has a steeper slope than the slower constant velocity buggy. This mean that the faster constant speed velocity covers more distances compare to the slower constant speed velocity at the same amount of time.

The name of the lab is “Drops on a Penny.” I was expected to find the independant variable, dependant variable, write a hypothesis, and test the experiment. After testing the experiment multiple times, I needed to find the average amount of drops for each trial, graph them, and tell what kind of relationship it is. The last thing I needed to do was rewrite the details of the project and write a conclusion. The point of the experiment was to have the students get used to the idea of a lab, and get familiar with independent and dependent variables.
What questions were asked? At the beginning of his observations Herschcel thought that the planted was a star. However, upon further observation he came to the conclusion that the plant did not move across the universe like the other stars did. After further analysis he soon realized that the object he once thought was a star was actually a planet. He tested this theory with
This lab covered how to use data to calculate the parallax and distance of items. Measuring angles of objects allows us to calculate the distance of these objects. It is also a way for astronomers to determine the distance of stars and other interstellar objects. I feel this is fundamental in gaining the knowledge of how to determine distances in general.
The purpose behind laboratory eleven was to learn about Lewis and VSEPR structure and use these to determine molecular geometry, electron geometry and polarity. According to our book, Chemistry the Central Science, “Molecular geometry is the arrangement in space of the atoms of the molecule.” And, “Electron geometry is the three dimensional arrangement of electrons around an atom according to VSEPR modeling.” Once these models were determined, it was easy to determine the shape of the molecule and whether the molecule is polar or nonpolar. If there is an error in the experiments likely resulted from my inability to use the balloons.
Noisy, and uncooperative students make Frank doubt the technique of using partners. Without success, Frank’s past two attempts of the lab need change. The first attempt separated the activity into stations, but this idea failed severely. While the second attempt required the students to do one process, a period seemed to work on paper, it was a recipe for
It could also help scientists to predict how the rings around planets outside of our own solar system may
Habitable planets are scarce but one will be filled with hope as it will become a home for the human race for millenniums to come; for now it seems Proxima b will have that honor. One of the most historic tools for space-bound research, the telescope is making astronomical bounds in assistance of astronomy research. The Hubble telescope is without a doubt the most influential telescope of all time. While not being the most powerful piece of equipment engineering has to offer, it has played the largest role of any telescope. “The Hubble Space Telescope is not the most prolific exoplanet hunter at astronomers ' disposal, but it has made unique and significant contributions to the discovery and study of dozens of far-off worlds.
Infrared observation works best for tracking relatively newer planets that give off more heat. Gravitational involves microlensing on the other hand works better for cooler planets. Gravitational microlensing involves
The astronomers who are working in the Kepler program were able to find that nearly twenty percent of all stars are Sun-like. This information provides that planets that are in the stars’ gravitational field are potentially habitable. The closest of these habitable zones is only about twelve light years away; one hundred twelve thousand, seven hundred forty years at twenty five thousand miles per hour. This particular habitable zone and its planets can even be seen by the naked eye. In total, of what we can see with telescopes and astronomical tools of that sort and interstellar machines, we know that there are approximately sixty billion habitable planets as of today.
In almost all cases, they are too far away to be seen by a telescope. Two notable methods used to detect exoplanets are the Doppler Method and Transit Method. Doppler Shift Method The doppler shift method works by analysing the doppler effect that occurs when a planet orbits its star. The doppler effect is when a small mass, such as a planet orbits around a larger mass, such as its star, which will cause a shift or wobble as both masses have a gravitational pull towards each other, thus they will both orbit a common central point.
