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.
Making Vocal Cords
Source Institutions
In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.
Supporting Structures
Source Institutions
In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.
Build a Borneo Glider
Source Institutions
In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So
Bending Light
Source Institutions
In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Breathing Machine
Source Institutions
In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.
Model Eardrum
Source Institutions
In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.
Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about
Rainbow Refraction
Source Institutions
In this activity, learners will explore how light can refract or break apart into different colors.
Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
Crazy Camouflage
Source Institutions
In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
