In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

This demonstration activity models how Venus appears from Earth.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this activity, learners construct a robot-like hand to demonstrate how data is collected when using robotic technology.

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

In this activity, learners build water-propelled engines from soft drink cans.
