Use a model to explore leaf photosynthesis and the macroscopic outcome of the photosynthetic reaction.

Sage Modeler is a systems modeling tool to facilitate the building of dynamic models.

Stebbins is a game about evolution. Students collect data as predators eating colored circles on a colored background, being careful to avoid the poisonous ones. Data analysis reveals how the population changes color over time, and can...

Steer a charged particle to a target, and observe forces and fields.

Modeling traffic data is important for urban planning, creating transportation systems, and even predicting how much foot traffic a retail store can expect in a given day. This genre of dynamic data science activities could be classified...

In this dynamic data science activity, students use data to build binary trees for decision-making and prediction. Prediction trees are the first steps towards linear regression, which plays an important role in machine learning for...

Working with large datasets that support exploration of patterns is an essential first step in becoming fluent with data. In this dynamic data science activity, students can access part of the U.S. Census Bureau's American Community...

Students act as astronomers, studying stars in a patch of sky in our own galaxy. Using simulated data from spectroscopy and other real-world instrumentation, students learn to determine star positions, radial velocity, proper motion, and...

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

Generate all polar, all nonpolar, or random proteins and observe how the protein folds in response to these molecular properties. Explore how the potential energy of the system changes over time to draw conclusions about how proteins...

Observe how molecules with hydrophilic and hydrophobic regions move in a mixture of oil and water, and pay attention to changes in potential energy over time. Move and rotate the molecules to see how they interact with their surrounding...

This activity places the control of the environment under the student's control. A field starts off with a uniform light level, and thus capable of growing plants with medium-sized leaves. Students can alter the environment by growing a...

Access and explore large datasets from the National Health and Nutrition Examination Survey (NHANES, 2003). Working with large datasets that emphasize exploration, finding patterns, and modeling is an essential first step in becoming...

In this interactive, drag a pendulum to set its initial height and observe how height is related to potential energy. Then release the pendulum and observe the change from potential energy to kinetic energy, and ultimately to thermal...
