### DESIGNING AND MODELLING AN IMPACTORCHAIN REACTION PROJECT

We are welcoming to all participants as the Turkish Partner of the Chain Reaction Project.

Here is our teacher, AydınDemirwho supports us during the 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 free-fall 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 plane that was arranged as diverse angles (heights) to model and concretely demonstrate the impacts of asteroids.

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.

FINDINGS design has not big size and is portable.

angle design has not big size and is portable.

- Increasing angle and diameter of the crater (mass is constant; mass=18,4)
- Increasing angle and diameter of the crater (mass is constant; mass=36,8)
3) Increasing angle and diameter of the crater (mass is constant; mass=99)

diameter

1) design has not big size and is portable.Increasing angle and deepnessof the crater (mass is constant; mass=18,4)

2) Increasing angle and deepnessof the crater (mass is constant; mass=36,8)

3) Increasing angle and deepnessof the crater (mass is constant; mass=99)

Conclusions design has not big size and is portable.

- 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.
- When the angle is increased deepness of the crater is increased, it seems to relatively independent from the mass of the meteor.
- Finally, mass of the meteor important but angle of the meteor also is an important factor in determining the crater diameter and deepness.
