What effect does geography have on air quality? Use this model to explore the effect of point-source pollution, geography, and wind on regional air quality.
Explore the interactions that cause water and oil to separate from a mixture. Oil is a non-polar molecule, while water is a polar molecule. While all molecules are attracted to…
This activity uses a model of the Virtual Ecosystem with three species in it: grass, rabbits, and hawks, enabling the students to explore the effect of predation on the prey…
If there are air leaks in a house, you might expect that their effect would be magnified on a windy day. The wind creates greater air pressure on the windward…
…maximum heights of the moving objects and discover how long each object is in the air before hitting the ground. Quadratic Word Problems Part 1 is the second of four…
…real-world data as you explore the interactions of factors that affect a region’s air quality. You will not be able to answer the module’s framing question at the end of…
The interactions of electrons with matter have great explanatory power and are central to many technologies from transistors, diodes, smoke detectors, and dosemeters to sophisticated imaging, lasers, and quantum computing….
Explore the role of charge in interatomic interactions. The forces attracting neutral atoms are called Van der Waals attractions, which can be weak or strong, depending on the atoms involved….
Explore how hydrophobic and hydrophilic interactions cause proteins to fold into specific shapes. Proteins, made up of amino acids, are used for many different purposes in the cell. The cell…
Observe how a chemical reaction evolves over time and affects the balance of potential and kinetic energy in the system.
