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.
Modeling Day and Night
Source Institutions
In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.
How Do Viruses Recognize a Target Cell?
Source Institutions
This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Space Stations: Bones of Contention
Source Institutions
In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.
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).
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
The Game of Life: Stem Cell Edition
Source Institutions
In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
Bend It, Break It
Source Institutions
In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.
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.
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.
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.
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
Pathways with Friends
Source Institutions
Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.
