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.
Exploring Tools: Special Microscopes
Source Institutions
In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.
Space Stations: Sponge Spool Spine
Source Institutions
In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Sled Kite
Source Institutions
In this activity, learners build a sled kite that models a type of airfoil called a parawing.
Going for a Spin: Making a Model Steam Turbine
Source Institutions
In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
Catapult
Source Institutions
In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.
Pyramids and Triangles
Source Institutions
Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.
Castle Basics
Source Institutions
In this four-day lesson, learners identify three-dimensional forms in castle design, research different parts of the castle with a focus on their uses, and design and enlarge a banner for the great ha
Living Bones, Strong Bones
Source Institutions
In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh
Exploring Strange New Worlds
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
Giant Museum: Create a Scale Model
Source Institutions
In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?
Earth's Water: A Drop in Your Cup
Source Institutions
This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
Make a Balloon-powered Nanorover
Source Institutions
In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.
I Want to Hold Your Hand
Source Institutions
In this activity, learners construct a robot-like hand to demonstrate how data is collected when using robotic technology.
