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.
Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.
Three Little Pigs
Source Institutions
In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.
Fossil Age Estimation Model
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa
Building a Community From the Ground Up
Source Institutions
In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit
Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.
Luminescence
Source Institutions
In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.
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.
Bird Feeders
Source Institutions
In this activity, learners build a bird feeder or feeders to attract birds for observation.
Cave in a Cup
Source Institutions
In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then
Walk On Water Bugs
Source Institutions
In this activity (on pages 29-35), learners examine water pollution and filtration.
Chromosome Models: Karyotyping
Source Institutions
This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos
Moonlight Serenade
Source Institutions
In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.
Tracking Otters
Source Institutions
This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.
Balloon Staging
Source Institutions
In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.
Digger
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.
Polar Opposites
Source Institutions
In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
Ice on Mars
Source Institutions
In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.
Build a Tree
Source Institutions
This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.
Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
