Recycling Rules: Understanding Recycling and a MRF
Source Institutions
In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
MarsBound!: Mission to the Red Planet
Source Institutions
MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.
Exploring Materials: Graphene
Source Institutions
In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.
We Have Capture!
Source Institutions
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.
Off Base
Source Institutions
In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
Biomimicry: Synthetic Gecko Tape Through Nanomolding
Source Institutions
In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
Stabilization Wedges Game
Source Institutions
This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.
Tools of Magnification
Source Institutions
In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.
Water Tower Challenge
Source Institutions
In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.
Sticky Engineering Challenge
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.
Wind Tunnel Testing
Source Institutions
In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.
Life Vest Challenge
Source Institutions
In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.
Clipper Creations
Source Institutions
In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.
Target Practice
Source Institutions
In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
Interactive Gumball Machine
Source Institutions
In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
Keep Out!
Source Institutions
In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.
Extreme Kicking Machine
Source Institutions
In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.
Blowin' in the Wind
Source Institutions
In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.
Infrared Investigations
Source Institutions
In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
