http://www.chm.davidson.edu/vce/index.html: Virtual Chemistry Experiments. This is a series of tutorials, or learning progressions, on topics gasses and chemistry. The experiments are a bit difficult to run at times. Perhaps very good, or good. Chemistry focus so there are some physics mistakes in the material, but overall it can be useful for thermodynamics classes.

Singapore Air Quality Data Visualization PSI Tool

Singapore Air Quality Data Visualization.zip
Singapore Air Quality Data Visualization.html

Explore real environmental data with this interactive PSI (Pollutant Standards Index) visualization tool. Students can analyze air quality trends across Singapore's regions, comparing PM2.5, PM10, and O3 levels over different time periods and seasons.

Data Features:

• Real Singapore air quality data

• Multiple regions (North, South, East, West, Central)

• Different pollutants (PM2.5, PM10, Ozone)

• Time series visualization

• PSI scale with health categories

PSI Scale:

0-50: Good (Green)

51-100: Moderate (Yellow)

101-200: Unhealthy (Orange)

201+: Hazardous (Red)

Learning Objectives:

Read and interpret line graphs

Compare data across regions

Identify trends and patterns

Understand environmental health impacts

Develop data literacy skills

Scientific Inquiry:

Pattern Recognition: When is air quality worst?

Comparison: Which region has cleanest/worst air?

Causation: What events affect air quality?

Prediction: Based on patterns, what happens next?

Real-World Context: Connect to haze events

Classroom Integration:

Geography: Singapore regions and environment

Science: Air pollution and health

Math: Graph interpretation and statistics

Civics: Environmental responsibility

Current Events: Link to real news about haze
