Data Plotting and Fitting
This Data Plotting and Fitting page was developed as a third year laboratory for the School of Physics, University of New South Wales. The program will plot data into several different graphs. Graphs include a line graph, linear regression fit, exponential fit, power fit, Gaussian fit and Cos squared fit. The program can also calculate fit for the data if required.

Daisy World Model
The Daisy World model is intended to illustrate a mechanism through which biota might optimize their environment by means of negative feedback. The model offers a very simplified approach to a feedback system and can provide an introductory lesson in how models work. The aim of the model is to implement and test a mathematical model describing possible influence of biota on an abiotic (climatic) system using GAWK and GNUPLOT. The model tests the hypothesis that biota can influence the planetary

Central Limit Theorem Applet
The Central Limit Theorem applet demonstrates the central limit theorem using simulated dice-rolling experiments. An "experiment" consists of rolling a certain number of dice (1-5 dice are available in this applet) and adding the number of spots showing. This experiment is "performed" repeatedly, keeping track of the number of times each outcome is observed. These outcomes are plotted in the form of a histogram. According to the Central Limit Theorem, if the number of dice rolled is not too smal

Sun's Impact on Earth's Temperature
In this activity, middle school students view NASA images and movies of Venus, Earth, and Mars to deduce weather patterns and manipulate computer models to test competing hypotheses. By completing this activity, the learner will compare weather patterns observed on Venus, Earth, and Mars; manipulate computer models to investigate the influence of solar distance and atmosphere; evaluate various solar system hypotheses using a computer model.
