Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.
Avalanche
Source Institutions
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.
Erosion and Floods
Source Institutions
In this activity, learners create models of erosion and floods and learn to recognize both in their environment.
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Pollution and Lung Health
Source Institutions
Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
Catapult
Source Institutions
Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.
Pocket Solar System: Make a Scale Model
Source Institutions
This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
LEGO Orrery
Source Institutions
Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.
Biobarcodes: Antibodies and Nanosensors
Source Institutions
In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.
Mystery Tubes
Source Institutions
Learners investigate a pre-constructed mystery tube to determine its interior mechanism.
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.
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.
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.
The Squeeze Box
Source Institutions
In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.
Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.
