Science Topics

SimScientists focuses on topics in middle school science in which students learn concepts that involve understanding systems in the world around us. Our work is based on helping students to reason with and about models of science systems.

Ecosystems covers students' understanding of the roles of organisms in food webs and the interdependencies among them. Students observe organisms, create food webs, explore population models, and design experiments about limiting factors.


Atoms and molecules covers the nature of matter, the relationships between energy and the physical states of matter, and how chemical changes occur. Students make predictions, design experiments and analyze data.


Climate includes developing an understanding of the relationship between the latitude and differential heating and how it affects climate patterns. Students describe and interpret observations, predict relationships, vary model parameters to simulate climate characteristics.
