Curious Crystals
Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Grow an Alum Crystal
What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and water. You may...

Crystal Ice Art
This isn't just an art lesson, it's a science lesson too. Kids draw a lovely winter scene and then paint over it with a solution of epsom salts and water. They make predictions, then observe how crystals form as the water evaporates...

Ghost Crystals - Light & Water
Woo, ghost crystals, just in time for Halloween! Young scientists experiment with light and water as they make and observe ghost crystals. The lesson does not include the process for making the crystals, but provides a web link where a...

Why Does Water Dissolve Salt?
Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule.

Crystal Growing
Students grow crystals and document their observations by recording timeing and growth. Additional characteristics of crystals are observed under a black light, by growing under different conditions and mineral content is determined.

Properties of Salt
Young scholars see how the properties of salt affect the color of flame, the flow of electricity, and the freezing temperature of water. They identify salt and sugar crystals under a microscope and discuss various practical uses of salt.

Snowflake Bentley
Students explore crystals through the story Snowflake Bentley and then create crystal pictures of their own. In this interdisciplinary instructional activity, they create a crystal web chart on chart paper, design artificial snowflakes,...

Properties of Salt
Students discuss certain properties of salt and how it is used every day as well as harmful uses. They experiment with salt to see it conduct electricity, form crystals and water freezing temperature. They complete a worksheet to record...

Crystals
Young scholars investigate patterns in solids, the structures of crystals and rocks made up of minerals. In this crystals lesson plan, students review solids, make patterns with Styrofoam balls, make crystals in the lab and observe their...

Watching Crystals Grow
Students observe crystal growth of Epsom salts and the variables that hinder or help their nucleation and growth. They illustrate a series of drawings/pictures as the crystals grow. They look for the different shapes they form as well...

Crystals: What Are They and What Holds Them Together
Students are introduced to the characteristics of crystals and what keeps them together. Using the Periodic Table, they examine the various elements and develop a model of an atom. In groups, they place sugar and salt in petri dishes...

Using Dissolving to Identify an Unknown
There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Hydrated Salt
Students plan, design, and carry out an experiment to determine an empirical formula for a hydrated salt X that tell students when all the water has been removed from hydrate crystals.

Growing A Coral Skeleton
Students research the growth of coral. In this coral polyps lesson, students simulate the growth of coral by using available materials to grow crystals. Students record observations in a scientific journal.

You've Got to Be Cool to Make Igneous Rocks
Students describe how igneous rocks are formed, design a classification system to group igneous rocks and develop a controlled experiment to prove that the rate of cooling affects the size of the crystals.
