Impact Simulator
Disasters: Geology vs. Hollywood
Introduction
As we have discussed in class, the Earth has been hit by objects from space in the past, and it will be hit
again in the future. Now, we don’t know what this would look like, but we make some predictions on the
effects of the impact through modeling. In this activity, you will be using an impact simulator to see what
would happen if/when the Earth is hit by another object from space
.
Learning Objectives
●
Visualize how different size objects can impact the Earth.
(1, a)
●
Apply students’ understanding of recurrence interval and probability.
(1, 2, 5, a)
●
Critically analyze governments’ role in preventing hazards.
(2, 5, a, b)
Part 1
: The simulator
This activity uses the website simulator
Down2Earth
. You can vary any facet of an asteroid impact and
see the damage that results. Before we begin, I encourage you to play around with the website. Change
the parameters (distance from the impact site, etc.), look at the data view, etc., just to get acquainted with
the details of the simulator
.
For this activity, we are standardizing certain details. A couple things before you get started: pay attention
to units (i.e. km, mi, in, ft, etc.) and click on the “data view” for impact details
.

surface at a velocity of 9.54 km/s
2.
What type of damage would you expect to see at a distance of 5 km?
Small buildings made of primarily wood would collapse, windows and bridges would collapse,
trees would blow away.
