Exploring Materials: Liquid Crystals
Source Institutions
In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
Which Powder is It?
Source Institutions
In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Changing Colors
Source Institutions
In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.
Finding Colors
Source Institutions
In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.
Whale Cart
Source Institutions
In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).
Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
Exploring Structures: Butterfly
Source Institutions
In this activity, learners investigate how some butterfly wings get their color.
Bubbles: Using Controls
In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.
Sand, Plants and Pants
Source Institutions
In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
