Mystery Tubes
Source Institutions
Learners investigate a pre-constructed mystery tube to determine its interior mechanism.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.
Visualizing How the Vestibular System Works
Source Institutions
In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the
Make a "Mummy"
Source Institutions
The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.
Pathways with Friends
Source Institutions
Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.
Earthquake Science: Soil Liquefaction
Source Institutions
This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Macromodel of Microarray
Source Institutions
This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.
The Model Neuron
Source Institutions
In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.
Wind Turbine
Source Institutions
Learners build a wind turbine and test it to see how much energy is created.
Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.
A Mole of Gas
Source Institutions
In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.
Gumdrop Chains and Shrinky Necklaces
Source Institutions
In this activity, learners thread gumdrops together to make a model of a polymer.
Exploring Earth: Land Cover
Source Institutions
This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
Macro-Microarray
Source Institutions
In this activity, learners explore the "nuts and bolts" of gene chips.
Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
