Edible Model of the Sun
Source Institutions
In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.
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.
Invent an Animal
Source Institutions
In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.
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.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
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.
Wind Tube
Source Institutions
In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.
Exploring the Universe: Static Electricity
Source Institutions
This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.
Fossil Dig Site
Source Institutions
In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.
Bird Feeder
Source Institutions
In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.
Black Holes: No Escape
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
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.
Exploring the Solar System: Moonquakes
Source Institutions
In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.
Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
Build A Battery
Source Institutions
The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w
Gravity and Falling
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.
Make a Lake
Source Institutions
Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?
Layered Fossil Parfait: Deeper is Older
Source Institutions
In this activity, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.
Balloon Nanotubes Tabletop
Source Institutions
This activity introduces learners to the structure and properties of carbon nanotubes.
Exploring Forces: Static Electricity
Source Institutions
In this activity, learners investigate what happens when you build up static electricity on plastic balls.
