Caution! Wildlife Crossing
Source Institutions
In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.
Chemical Footprint—Family Activity
Source Institutions
In this multi-part activity learners examine non-point water pollution.
Trading Places: Redox Reactions
Source Institutions
Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.
Box Ecology
Source Institutions
This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.
Tiny Particles, Big Trouble!
Source Institutions
In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Forwards and Backwards: pH and Indicators
Source Institutions
Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).
Paper Animals
Source Institutions
This resource contains ideas and brief instructions on how to build animals out of construction paper and other simple materials.
Robot Hands
Source Institutions
This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.
Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
Designer Ears: Make “better” ears!
Source Institutions
Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.
Seed Orbs
Source Institutions
In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.
Lever Cowboy
Source Institutions
In this activity, learners build a figure that moves and "comes to life" when they pull its string.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
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.
Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
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.
Bark Beetle Infestation Investigation: Estimation and Pheromones
Source Institutions
This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.
