Mavrix Crater Ball – Gift Giant

Balls of similar mass and varying diameters were chosen for this experiment. Again the drop height was kept constant at 35cm and the balls were dropped 3 times. The surface of the moon is marked by millions of craters, some are just a few metres long and some hundreds of kilometres. Most formed a long time ago when comets, asteroids and meteorites crashed into the moon’s surface. Craters on Earth This first experiment is a fairly simple one, however it is necessary – it will serve as a test for the equipment and methods used. By piecing together this evidence, scientists can study craters on Earth and link them to different periods of Earth's history. This involves many different types of scientists, including astronomers, geologists, chemists, paleontologists, and meteorologists (who actually study weather, and not meteorites). This has led to an interesting hypothesis being proposed about the formation of a sea, the extinction of the dinosaurs, and even the origins of life!

The pressurised suits severely restricted movement, and due to their helmet's visors they struggled to even see their feet. Some volcanoes are calm enough that scientists can get close to the lava in the summitcrater. Mount Erebus, a volcano in Antarctica, has a lava lake in its summitcrater. Lava lakes are where magma has bubbled up to the surface. Volcanologists can fly over Mount Erebus’ summitcrater to see how the lava lake is behaving and predict future behavior. The second graph also seems to show a linear relationship, but once again a single anomalous result is apparent. The large depth for the drop from 50cm suggests that the sand might have been less compact than usual, as this would have meant that the ball penetrated deeper than usual, with the grains being further apart. f) Was the flour visible at any time during the investigation i.e. in some impacts, or all impacts or none? Flatten the flour/cocoa surface and repeat the experiment twice more with the same impact object, adding the results to your table.

Sprinkle the surface of the flour with a thin layer of cocoa powder. Make sure it is evenly spread. Drop the impact object from this height and use the stopwatch to time the descent. The stopwatch must be stopped once the impact object has hit the flour/cocoa. On the left axis (y-axis), plot the average diameter of the crater (in cm), and on the bottom axis (x-axis), plot the diameter of the meteorite (in cm). Floor: bowl shaped or flat, characteristically below surrounding ground level unless filled in with lava. Another linear relationship – this time it is looser though. This could be due to the masses of the balls being slightly different. It was very difficult to find balls with similar masses – it would have been near impossible to find so many balls with identical masses.The issue is that there are multiple crater scaling laws, each with different assumptions, as Horedt & Neukem (1984) show (title of paper is Comparison of six crater-scaling laws). Need it in a hurry? We are also able to offer before 12 noon and Saturday delivery services. See here for information on these services The impact was so powerful the crater is called the Chicxulub Extinction Event Crater. Scientists say half the species on Earth—including the dinosaurs—went extinct as a result of the impact. The event was more than a billion times more explosive than all the atomic bombs ever detonated on Earth.

Apart from this one result, the graph clearly shows a linear relationship between the height dropped and the resulting impact crater. The next graph (overleaf) is possibly the weakest set of results. The depth once again has not been affected by the velocity of the ball, so this is encouraging. The angle of impact must be the only factor affecting the depth of a crater.Calculate the average crater diameter by adding up the three measurements and then dividing your answer by three. Write the answer in your data table.

Ejecta rays: blanket of material surrounding the crater that was excavated during the impact event. Ejecta becomes thinner away from the crater.
bright streaks starting from a crater and extending away for great distances. See Copernicus crater for another example. Durian and his colleagues dropped balls of many different materials and densities–from silicone rubber to ceramic–into materials such as sand, popcorn, and ice cream sprinkles. But the materials didn’t matter much; the depth was mainly affected by the density and diameter of the ball and the height from which it was dropped. Their crater diameters followed the “energy to the 1/4 power” rule of thumb, but the depth didn’t depend on energy in a simple way. This result doesn’t contradict the work of de Bruyn’s team because the UCLA researchers defined depth by measuring to the bottom of the buried ball, which was deeper than the bottom of the crater. Repeat steps 4-10 for all of your objects, each time recording the diameter of the three craters and the averages in the data table in your lab notebook. Impact craters are not unique to the Moon. They are found on all the terrestrial planets (Mercury, Venus, Earth and Mars) and on many moons of the outer planets. John de Bruyn, of Memorial University of Newfoundland in St. John’s, Canada, says that his group wasn’t originally interested in craters at all, but was considering the crown-shaped splash that appears when an object is dropped into a liquid. “We had just acquired a high-speed camera, and my post-doc was interested in seeing crown splashes in sand.” It turned out that sand doesn’t splash like a liquid, but the resulting pits looked a lot like craters on the moon.

Refer to your spreadsheet. Using the two equations below, calculate the kinetic energy of each impact object as it hit the surface. Notice how the marbles make craters in the pan. The soil below the surface ( white flour ) is brought to the surface.
