Rock On!

Vocabulary development can depend on many things, repetition, connections, visuals, conversation, and, of course, interest. Children, no matter their age, deserve the real words to describe what they are desiring to learn about. All of my vocabulary cards are written with this idea in mind.

Yesterday I posted the igneous rock. I love to talk with my students about the Latin root of igneous igne meaning fire.  They usually have heard of ignite and ignition. Some of the other words are ones I never knew until I was ready to learn them with my kids!

igneous (adjective)

1. Of fire, fiery; typical of fire; relating to or characteristic of fire. 2. In geology, formed by solidification from a molten or partially molten state (used of rocks or relating to rocks so formed): “Granite and basalt are igneous rocks.” 3. Relating to a rock that was formed by solidification from molten or partly molten material; one of the three principal classification of rocks along with metamorphic and sedimentary: “Such materials are a result of, or are produced by, the action of great heat.”
ignescent (adjective)
A reference to something that produces sparks of fire or that which can emit sparks or burst into flame: “He was using ignescent flint to cause sparks.”
ignible (adjective)
Something which is able to cause sparks or fire: “Since he had ignible trash, it was easy to burn all of it in the fire place.”
ignic (adjective)
Of or pertaining to fire: “The ignic heat from the fireplace helped to keep them warm during the winter.”
ignicolist (s), ignicolists (pl) (noun forms)
A fire-worshipper or fire-worshippers: “There were ignicolists who were known to worship fire as a form of a god.”
ignitable(adjective)

That which can be burned or set on fire.
ignite
1. To cause to burn. 2. To set fire to. 3. To subject to great heat, especially to make luminous by heat. 4. To arouse or kindle the passions of ; excite.
igniter
1. One who ignites. 2. A device to set fire to an explosive or combustible.
ignition
1. An electrical system, usually operated by a magneto or battery, that provides the spark to ignite the fuel mixture in an internal-combustion engine. 2. The point at which a substance begins a process of combustion, or the means by which this process begins.Ignitionoccurs when the heat produced by a reaction becomes sufficient to sustain a chemical reaction.Today’s word is metamorphic rock. It’s name comes from Greek roots. Metamorphic comes from the Greek words meta and morph. Meta means change and morph means form. So we get metamorphic meaning to change form. That is just so cool to kids, like a transformer or a shape-shifter!
