What's Going On

We're working hard on understanding matter and changes in matter.

Vocabulary Quiz Friday 12/2

Update

We wrapped up our Weather and Water Cycle Unit and have begun learning about matter.

No tests scheduled this week.

Here are the new vocabulary words and definitions

Vocabulary Matter/Changes in Matter

Matter—Anything that takes up space and has mass.

Element—a pure substance that cannot be broken down into simpler substances by chemical reactions

Atom—the smallest unit of an element that has the properties of that element

Molecule—two or more atoms joined together

Property—a characteristic or quality of a material or substance. These properties include: mass, volume, density, shape, color, hardness, texture, odor, taste, attraction to magnets and temperature.

• Mass—The amount of matter a substance or object has.
• Volume—The amount of space an object or substance occupies.
• Density—a measure of how many particles are packed together into a certain amount of space

State of matter—The form matter can take (e.g., solid, liquid, gas).

• Solid—matter with a fixed volume and shape
• Liquid—a state of matter with a defined volume but no defined shape
• Gas—a state of matter without any defined volume or shape

Change of State - the process of changing (by heating or cooling) one form of matter into another form of matter with different characteristics

Physical change—A type of change that involves the physical properties of a substance.

Chemical Change—a chemical reaction; a process that changes a substance into new substance

Mixture—a combination of substances that can be physically separated from one another

Dissolve—to add a solid material to a liquid in such a way that its particles completely disperse into the liquid, usually becoming invisible within the liquid

Solution—a mixture in which a solid and a liquid or two liquids are mixed so evenly, that it is not possible to see the separate particles

Suspension—a heterogeneous mixture in which fine particles are suspended in a liquid or gas where they are supported by buoyancy

Solubility—the ability of a substance to be dissolved in a liquid

This Week....

Working on our weather unit.  Student have been recording weather data.

Vocabulary Quiz will be Friday on the Weather and Water Cycle list.

We've been learning about different Native American groups.  Student are working to create books for a kindergarten class.  These look AMAZING!
