7th Grade Science
a. Matter and Properties
b. Quarter: One
II. Unit 1: Properties of Matter Unit Length 4 weeks
During this unit, students will realize that matter is anything that has mass and takes up space. That element’s are the basic building blocks of matter and can be identified by their physical and chemical properties. Furthermore, students will use the periodic table to gather information about the properties of oxygen, hydrogen, carbon, iron, and aluminum. Students will then be introduced to measurement skills needed to make observations and gather information and use mathematical operations to analyze and interpret data. In addition, students will identify questions to be answered through scientific investigation.
b. Standards for Unit #1:
CT State Grade Level Expectations (Draft)
GRADE-LEVEL CONCEPT 1:u Mixtures are made of combinations of elements and/or compounds, and they can be separated by using a variety of physical means.
GRADE-LEVEL CONCEPT 2: u Pure substances can be either elements or compounds, and they cannot be broken down by physical means.
SCIENTIFIC LITERACY TERMINOLOGY: Characteristic property, mass, weight, volume, density, solubility, boiling point, mixture, solution, particle, atom, element, molecule, compound, metal, non-metal, chemical reaction
