CSERD: NSDL Computational Science Pathway
What is Computational Science?
uses models to demonstrate and visualize concepts
Computational Science…
New Moon? Full Moon?
uses real-life situations to teach inquiry-based math and science concepts
Computational Science…
Greater than 340? Less than 340?
Estimator: The number of stars is greater or less than 340
Computational Science…
helps students learn how to use technology to solve problems
Topples Stands
Computational Science…
uses interactive tools to observe and analyze data

Modern science and mathematics
are more concerned with
pattern recognition and characterization
than with mere symbol manipulation.

Given: If 1 tree is on fire there is a 100% probability that the tree next to it will catch.
Predict: How much of the forest will burn?
Exactly 0% 0%-50%
50%-100% Exactly 100%
Given: If 1 tree is on fire there is a 0% probability that the tree next to it will catch.

Interactivate’s Scatter Plot Activity
Data Points0, 01, 100
As a scatter plot our data looks like:
Given: If 1 tree is on fire there is a 50% probability that the tree next to it will catch.
Predict: How much of the forest will burn?

Interactivate’s Scatter Plot Activity
Red Data Points(0, 0)(1, 100)Blue Data Points(0, 0)(0.5, 45)(1, 100)
As a scatter plot our data looks like:
Hmm… How could we find the overall pattern?
Recognizing the PatternResulting
graph in green from averaging
10 burns at each of the following
probabilities: 0, 0.1, 0.2,
0.3, 0.4, 0.5, 0.6, 0.7, 0.8,
0.9, 1
• Computers help us to model and simulate real world phenomena so we can better understand the world around us.
Would you have predicted that pattern?
The model is only as good as the design.
How does the Fire!! model relate to the real world and how does it not?
