Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

Landing the Rover
Source Institutions
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).

Mold Growth
Source Institutions
In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

How Quick Are Your Responses?
Source Institutions
In this activity (on page 134 of the PDF), learners explore reaction time.

3...2...1 Puff!
Source Institutions
In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

My Angle on Cooling: Effects of Distance and Inclination
Source Institutions
In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

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

Making Regolith
Source Institutions
This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Cooling Off
Source Institutions
In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

How Long Can You Hold Your Breath?
Source Institutions
In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

Particle Detection
Source Institutions
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.

FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

Newton Car
Source Institutions
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.

Out of Sight: Remote Vehicle Activity
Source Institutions
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.

Counting Your Lucky Stars
Source Institutions
In this activity, learners sample a star field to estimate the number of stars in the universe.

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

Size, Mass, Area, and Volume
Source Institutions
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.

Angles and Area
Source Institutions
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.

Crew Strength Training
Source Institutions
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.
