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.
Macro-Microarray
Source Institutions
In this activity, learners explore the "nuts and bolts" of gene chips.
Clay Bridges
Source Institutions
In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.
Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.
Column Chromatography
Source Institutions
In this activity, learners separate the components of Gatorade using a home-made affinity column.
To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).
Gas Model
Source Institutions
This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.
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.
Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.
Cylinders and Scale
Source Institutions
In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.
Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
Viral Packaging
Source Institutions
In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.
Breakfast Proteins
Source Institutions
In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.
Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.
Carbon Configurations
Source Institutions
In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.
Make Your Own Telescope
Source Institutions
Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.
Ionic Bonding Puzzle Lab
Source Institutions
In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.
Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
Toilet Model
Source Institutions
In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.
