Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
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).
Going for a Spin: Making a Model Steam Turbine
Source Institutions
In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
Geometry and Algebra: The Future Flight Equation
Source Institutions
In this activity, learners discover how NASA engineers develop experimental aircraft.
Design a Lunar Rover!
Source Institutions
In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
Heavy Lifting
Source Institutions
In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).
Design a Landing Pod!
Source Institutions
In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).
Strengthen a Paper Bridge
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.
Understanding Albedo
Source Institutions
In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
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.
Traveling Nanoparticles Model
Source Institutions
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.
The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
Marble Run!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.
