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 robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

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

In this activity, learners sample a star field to estimate the number of stars in the universe.

In this activity, learners use simple materials to construct a balloon-powered pinwheel. The pinwheel is a great way to investigate Newton's Third Law of Motion.

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 design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners construct a simple air pressure launcher for paper rockets.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

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

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids.

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.

In this sunny day, outdoor activity, learners observe changes in shadows over time. The activity also helps to develop a sense of the Earth's motion.

In this activity, learners will train to develop upper and lower body strength in their muscles and bones by performing body-weight squats and push-ups.

In this activity (on pages 11-12 of PDF) learners create models of lava layers that have formed on the moon.
