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.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Diaper Dissection
Source Institutions
This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.
Supercooled Water Drops
Source Institutions
In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.
Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.
Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.
Crystal Stencil Stars
Source Institutions
In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.
Salt Crystal Garden
Source Institutions
In this activity, learners will explore saturated solutions and discover how crystals form.
Growing Rock Candy
Source Institutions
In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.
Crystals: Grow Your Own Garden
Source Institutions
In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.
