Lunar Lander

(View Complete Item Description)

Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.

Folds and Faults

(View Complete Item Description)

In this activity, students will learn how rock layers are folded and faulted and how to represent these structures in maps and cross sections. They will use playdough to represent layers of rock and make cuts in varying orientations to represent faults and other structures.

Material Type: Activity/Lab, Interactive

Seismic Activity

(View Complete Item Description)

This laboratory activity demonstrates how seismic waves are generated and helps students understand how they can reveal the composition of Earth's inner layers. Students will construct models by filling shoe boxes with various materials, drop rocks on them to generate 'seismic waves', record the waves, and make observations about their differences.

A Flipped-Class Atmospheric Science Curriculum for Middle School Educators

(View Complete Item Description)

Members of the Department of Atmospheric Sciences at the University of Illinois Urbana-Champaign have designed a suite of atmospheric science learning modules for middle school students. The curriculum, which implements a flipped-classroom model, is cross-referenced with Common Core and Next Generation Science Standards. It introduces students to topics such as temperature, pressure, severe weather safety, climate change, and air pollution through short instructional videos and critical thinking activities. A goal of this project is to provide middle school science educators with resources to teach while fostering early development of math and science literacy. The work is funded by a National Science Foundation CAREER award. For a complete list of learning modules and to learn more about the curriculum, visit
