Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

Build A Treetop Walkway
Source Institutions
Build and test a scale model of a rainforest canopy walkway.

Exploring at the Nanoscale
Source Institutions
This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

Portable Sundial
Source Institutions
Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

Paddle Boat
Source Institutions
In this activity, learners build an old-fashioned paddle boat out of simple materials.

Above Water: Buoyancy & Displacement
Source Institutions
In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

Wash This Way
Source Institutions
In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways

A Simple Escapement Mechanism
Source Institutions
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

The Squeeze is On
Source Institutions
Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

Spinning Illusions
Source Institutions
In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.
Building a Community From the Ground Up
Source Institutions
In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

Design a Park
Source Institutions
In this activity, learners are invited to imagine the park of their dreams!

Dinosaur Breath
Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Gelatin Used for Drug Delivery
Source Institutions
In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).

Tall Tower Challenge
Source Institutions
In this activity, learners will use their chosen material to build the tallest tower possible in under three minutes. This activity uses problem solving and fine motor skills to challenge learners.

What Color is Your Air Today?
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.
