Elements & Properties - All Activities
Spelling, matching, typing, and a study guide on one page. Reuse the same ELL-friendly definitions for Tier 2 and Tier 3 words from the Periodic Table and matter properties.
Beginner ELL Core Idea
- Matter has properties.
- Heat can change matter.
- Mass stays the same.

The columns of the periodic table. Elements in the same one share similar chemical properties.
Elements that have a mix of metal and nonmetal properties.
Elements that are typically shiny, bendable, and good at conducting heat and electricity.
Elements that typically lack shine and tend to be brittle rather than bendable.
The rows of the periodic table.
The characteristics that describe matter, such as color, hardness, or melting temperature.
The specific temperature at which a liquid turns into a gas.
How something appears to the eye, based on the wavelengths of light it reflects.
Substances made of two or more different elements chemically bonded together.
A measure of how well a material allows heat or electricity to pass through it.
The scientific rule that mass is neither created nor destroyed — it just gets rearranged.
A measure of how much mass is packed into a given amount of space.
The basic substances that make up all matter — each one cannot be broken down into anything simpler by chemical means.
A measure of how well a material resists being scratched or dented.
A measure of how easily a material can be bent or hammered into a new shape without breaking.
The specific temperature at which a solid turns into a liquid.
A chart that organizes all known elements by their properties and atomic structure.
A change of state — like solid to liquid, or liquid to gas — without changing what the substance is made of.
A measure of how well a substance dissolves in another substance, like sugar in water.
A measure of how thick and slow-flowing a liquid is.
