Dinosaurs-- Extinct?

For my science project, the topic that I have decided to do is one that I am very intrested in-- dinosaurs and what destroyed them.

What this comes down to is that I am trying to show how the dinosaurs came to be extinct and remake this in a controled enviroment. Here are the steps that I followed to make this happen:

1. I took 1 shoebox, filled it with dirt/soil.

2. I found a bunch of bugs/insects of all sorts and placed them carefully in the soil.

3. Placed the box full of bugs/insects onto the ground below the deck beside my house.

4. I went up on my deck and took 1 large rock (the largest I could find that would fit in the shoe box, this was the comet).

5. I dropped the comet from the top of my deck. It fell SO HARD down into the shoebox.

6. The comet exploded into the dirt (this represented the comet exploding into the dirt of the earth).

7. I took the box into the house and took a hairdryer and blew it into the shoebox to represent the heat blast that would have come from the comet but it was not quite hot enough the bugs just seemed to be made comfortble by this so I took the box and put it into the microwave and turned it on high for at least 3 mins., maybe more.

8. After I had blasted the bugs/dinousaurs with heatwaves from the comet, the ice age was of course close to follow so I put the shoebox with the bugs/dinosaurs into the freezer over night because the ice age lasted about a million or so years so I figured to make it scale that it should be left in there for good long while anyway.

9. After the box had been in the freezer overnight I took it out and examined the box carefully.

10. None of the bugs had survived as far as I could tell. They did not move an inch.

11. Therefore, I can say with confidence that none of the dinousaurs survived the comet blast or ice age. This was drawn from the dead bugs.  Therefore it is my conclusion that the dinousaurs are all dead.
