Chemistry Puns? I'm in my element (Image) linking to chemistry notes page from home page (and they might be giants - meet the elements)

BIG Ideas!!

1. Matter is made of both elements and compoounds.
2. Matter has physical properties that can be used for classification.
3. Matter has physical properties that can be used for classification and identification.
4. Chemical changes result in new substances with different properties.

Unit 3: Properties of Matter: The student will...

• know that an element and a compound are pure substances.

• know that elements are represented by chemical symbols and compounds are represented by chemical formulas

• recognize that a limited number of many known elements comprise the largest portion of solid Earth, living matter, oceans, and the atmosphere.

• compare metals, nonmetals, and metalloids using physical properties such as luster, conductivity, or malleability.

Unit 4: Density: The student will...

• measure and record the mass and volume of regular and irregular objects.

• calculate density.

• use density to identify an unknown substance.

Unit 5: Chemical Reactions: The student will...

• identify the formation of a new substance by using the evidence of a possible chemical change such as production of gas, change in temperature, production of a precipitate, or color change.
