Project.
PURPOSE OF THE PROJECT
Within this project our aims are to…
(1) investigate how the celestial bodies that may
crash into earth ground create craters
(2) establish a scientific model demonstrating
diameters and deepness of the craters
WHY WE STUDY AN IMPACTOR?
Since both amateur and Professional astronomers
have in wonder the effect of celestial bodies on earth
Our hypothesis: Our initial hypothesis is that
diameter and deepness of the craters depend on
hitting celestial bodys’ mass and angle of incidence
Link to school science: This project is about collision
course and we constructed a primitive impactor
DATA COLLECTION
We designed a system that we had chance to investigate how freefall objects have impacts the ground.
However, as we had seen from several videos no meteor or
asteroids do not smash into the earth surface like a free fall object
rather they hit with diverse angles.
Therefore, we intentionally changed the falling
angle of a meteor or an asteroid-like
substance that we used diverse sized marbles
We dropped the marbles from a specially designed inclined
plane that was arranged as diverse angles (heights) to
model and concretely demonstrate the impacts of
asteroids.
MATERIAL DESIGN PROCEDURES
In a fish tank we filled out soil to model the layers of the
earth. Fish tank is transparent, thus, layers are seen easily
The ground or the uppermost layer is filled with
flour to see the effects of hits of the marbles. Two
meters are fastened up to two edges of the fish
tank to measure angle and height.
An inclined plane is stayed to create angular smashing. Our
design has not big size and is portable.

Conclusions
1) When the angle is increased (from 10 to 80)
diameter of the crater seems to increased, but there
is critical point as 30 degrees, up to 30 degrees
diameter is increased, then for higher degrees
dramatically decreased.
2) When the angle is increased deepness of the crater
is increased, it seems to relatively independent from
the mass of the meteor.
3) Finally, mass of the meteor important but angle of
the meteor also is an important factor in
determining the crater diameter and deepness.
