The China Hammer Mystery
Source Institutions
In this activity, learners are asked to examine the differences between two materials in a pair.

Magnetic Sensory Bottles
Source Institutions
In this activity learners will investigate magnetic and non-magnetic items in a sensory bottle.

Clippy Island: An Investigation into Natural Selection
Source Institutions
In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

Exploring the Solar System: Moonquakes
Source Institutions
In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

Show Me the Money
Source Institutions
In this math lesson, learners make wallets or purses and then participate in a variety of money-related activities. First, learners make their own paper money and paper wallets or purses.

Chair Lift Challenge
Source Institutions
In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.

Electrolysis
Source Institutions
Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Trebuchet Toss
Source Institutions
In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

Weight in Space
Source Institutions
In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

Airfoils
Source Institutions
In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.

Water Breathers
Source Institutions
In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

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.

Microbes are Everywhere
Source Institutions
In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

Chemistry Makes Scents
Source Institutions
In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

Pages of a Forbidden Tome
Source Institutions
In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.
