Explore the pattern of earthquakes on Earth, including magnitude, depth, location, and frequency.
Virtually all traits are influenced by environmental factors as well as genetic information. Investigate the effect of both on the health of sand rats, a model for studying diabetes. Examine the genetic composition of sand rats, sort them into different pens, and vary the food source. Collect data to see how both food and genetics […]
How might Earth’s temperature change in the future? Use this model to explore how changing human emissions of greenhouse gases might affect the temperature. The model incorporates positive and negative feedback loops. Ice cover and cloud cover change in response to the level of water vapor and temperature in the model.
This model shows how the size of an object affects how much heat energy it holds and hence how much is needed to heat it up or cool it down. You can explore this by watching the heat transfer between two objects with different sizes and different temperatures.
This model shows how specific heat of an object determines how much heat energy it holds and hence how much is needed to heat it up or cool it down. You can explore this by watching the heat transfer between two objects with different specific heats and different temperatures.
Explore connections between electric forces and molecules using simulations, and explain energy transfers using the conservation of energy.
Develop atomic-level causal models to explain observations of electrostatic interactions.
Hydraulic fracturing is used to produce oil and natural gas from non-porous rock formations. Use this model to explore how such wells are drilled and fractured to release methane from a layer of shale. Like every energy-extraction process, there is the potential for contamination. Use the model to explore how contamination of aquifers might happen […]
Explore the polar molecule interactions known as hydrogen bonds. Despite the ‚Äúbond‚Äù name, hydrogen bonds are a special type of dipole-dipole interaction. Hydrogen bonds between two molecules (or within portions of a larger molecule) when hydrogen atoms bonded to highly electronegative atoms (such as nitrogen, oxygen, or fluorine) interact with electronegative portions of a different […]
Explore how states of matter are related to the strength of intermolecular attractions. The three common physical states of matter are solid, liquid and gas. All matter is made up of atoms, which make up molecules. Atoms and molecules can be weakly or strongly attracted to each other. The way that large molecules interact in […]
