Description

If you look at the words on a printed page through this crystal, you'll see double. These natural, nearly transparent crystals exhibit the property of "birefringence", i.e., they can break light into two distinct polarized beams. By rotating a polarizing filter over the crystal, it is possible to view one image at a time! This is a great hands-on demonstration and wonderful when displayed using an overhead projector. Each crystal is about 2 x 2 x 4 cm.

The crystals are pretty much exactly what I wanted for some laser experiments with birefringence. thanks, Bob

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary Middle School High School

2-PS1-1

Students can use Calcite to plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.

5-PS1-3

Students can use Calcite to make observations and measurements to identify materials based on their properties

DCI-2/PS1.A: Structure and Properties of Matter.

A great variety of objects can be built from a small set of Calcite pieces.

MS-PS1-1

Using Calcite, students can develop models to describe the atomic composition of simple molecules and their structures or properties.

MS-PS1-3

Students can investigate Calcite in an investigation to describe that synthetic materials come from natural resources and can have an impact on society.

HS-PS1-7

Students can use Calcite to construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the Periodic Table and knowledge of the patterns of chemical properties.

DCI-HS/PS1.A: Structure and Properties of Matter.

The Periodic Table orders elements horizontally by the number of protons in the atom's nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.
