Exploring Materials: Nano Gold
Source Institutions
In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.
Ramps 1: Let it Roll!
Source Institutions
In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.
Battleships: Searching Algorithms
Source Institutions
This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.
Wheat Evolution: Sedimentation Testing
Source Institutions
In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.
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
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Rubber Band Thermodynamics
Source Institutions
In this demonstration, learners explore the thermal properties of rubber. Learners investigate whether a rubber band contracts or expands when heated.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
One In The Hand
Source Institutions
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
How Do We Convert Electrical Energy into Mechanical Energy?
Source Institutions
In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.
Aerogel
Source Institutions
This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.
Conduction Countdown
Source Institutions
In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.
Shake and Make: Charge Recognition
Source Institutions
In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.
Strong Shapes
Source Institutions
Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!
Go Fly a Kite
Source Institutions
In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.
Smelly Balloons
Source Institutions
Are balloons porous or non-porous? In this activity, learners watch an entertaining Mr. O video and conduct a simple experiment to find out.
Card Flip Magic: Error Detection & Correction
Source Institutions
This magic trick is based on how computers detect and correct data errors.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
