Mavrix Crater Ball, High Density PU Bouncy ball

Product Information

Notice how the marbles make craters in the pan. The soil below the surface ( white flour ) is brought to the surface. The semi-log graph certainly shows a straight line, so the relationship between drop angles greater than 25 degrees and the crater length is exponential. However this still leaves the question of those early angles, why aren’t they following any kind of trend?

Harvey, Samantha, et al. (2013, July 2). Meteors & Meteorites: Overview. National Aeronautics and Space Administration (NASA). Retrieved July 11, 2013. Firstly, for the final experiment, the landing tray was not long enough to slow down balls travelling at high speed. A longer tray would have been able to produce a wider range of results. Central uplifts: mountains formed because of the huge increase and rapid decrease in pressure during the impact event. They occur only in the center of craters that are larger than 40 km diameter. 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.Coming in a bright neon purplecolour, they're easy to follow in the air.Bounce it on walls, pavements and any other hard surface, play a game with your friends and see who can bounce it higher!

Why do craters form?

The crater length does indeed vary proportionally to the vertical height, but the crater depth appears to have no relationship whatsoever with the height (therefore the entry speed). It only appears to be affected by the entry angle, which determines the vertical component of the velocity. So this is due to the independence of horizontal and vertical motion – a law which is well demonstrated here. However the length of the crater did not show any strong relationship with the drop height. I would have expected the craters to get shorter as the vertical drop height increased (due the vertical component increasing), which has happened very loosely. The results for this relationship are not sound enough for a conclusion to be made. Fill the pan about 2 cm deep with flour, lightly sprinkle the drinking chocolate to cover the entire surface. b) how did the density of the impact object affect the size of the crater? Did this affect the ejecta rays?

After carrying out the above activity, hand each student a worksheet. Ask them to answer and discuss the questions provided. I would challenge any club golfer to go to their local course and try to hit a six-iron, one-handed, with a one-quarter swing out of an unraked bunker. There are meteoroids traveling around throughout space, and all of the moons and planets have been impacted by meteorites since the formation of our solar system. (Note: they are called meteoroids when they're still in space, and meteorites when they land on a planet or moon). On Earth, we only see a few impact craters because of a couple of different reasons. First, most meteoroids never reach the Earth's surface because they burn up in the atmosphere. This is what we are seeing when we watch a shooting star during a meteor shower ( meteor refers to the visible streak of light). Second, impact craters from meteorites can be changed by geological forces (like earthquakes and continental movements), or eroded away by atmospheric forces (like wind or rain). There is no atmosphere on the moon, which means that falling meteoroids do not burn up and there is no weather to erode away the craters. In fact, the footprints of the astronauts who landed on the moon over 30 years ago are still there, perfectly preserved! Volcanic material in some summitcraters is near the surface, but not visible. Although Mount Fuji is an active volcano and magma and gases sit below the summitcrater, the risk of an eruption is very low. Mount Fuji, Japan’s highest mountain, is one of the most popular places in the country to hike. The pressurised suits severely restricted movement, and due to their helmet's visors they struggled to even see their feet.

Preliminary Experiments

After the "meteorite" impacts the flour, carefully remove the object without disturbing the "crater" left behind. Look at the last five points on the graph – they seem to show a type of exponential shape. The only way to know for sure is to plot a graph of log length against Angle for those last five points. The semi-log graph should be a straight line, if the relationship is exponential.
