SC.912.P.8.1

Differentiate among the four states of matter.
General Information
Subject Area: Science
Grade: 912
Body of Knowledge: Physical Science
Idea: Level 2: Basic Application of Skills & Concepts
Standard: Matter -

A. A working definition of matter is that it takes up space, has mass, and has measurable properties. Matter is comprised of atomic, subatomic, and elementary particles.

B. Electrons are key to defining chemical and some physical properties, reactivity, and molecular structures. Repeating (periodic) patterns of physical and chemical properties occur among elements that define groups of elements with similar properties. The periodic table displays the repeating patterns, which are related to the atom's outermost electrons. Atoms bond with each other to form compounds.

C. In a chemical reaction, one or more reactants are transformed into one or more new products. Many factors shape the nature of products and the rates of reaction.

D. Carbon-based compounds are building-blocks of known life forms on earth and numerous useful natural and synthetic products.

Lesson Plans

Modeling the Kinetic Theory:

Students will engage in a directed inquiry lab to model the kinetic theory of matter. In the end, students should have a firm grasp of how matter's behavior is changed when its structure is changed during phase transitions.

Type: Lesson Plan

Why so dense?:

  • This lesson is designed as an introduction to standard SC.912.P.8.1 and allows students to compare the properties of the three main phases of matter (solid, liquid, and gas) before competing cooperatively to build the most dense or solid structure possible in a guided inquiry activity.
  • The lesson plan follows the 5E model and incorporates elements of the guided inquiry and POE (predict, observe, and explain) models. Students will be evaluated summatively with the use of argument building.

Type: Lesson Plan

BIOSCOPES Summer Institute 2013 - States of Matter:

This lesson is designed to be part of a sequence of lessons. It follows CPALMS Resource #52957 "BIOSCOPES Summer Institute 2013 - Thermal Energy" and precedes CPALMS Resource #52961 "BIOSCOPES Summer Institute 2013 - Solutions." The lesson employs a predict, observe, explain approach along with inquiry-based activities to enhance student understanding of states of matter and phase changes in terms of the kinetic molecular theory.

Type: Lesson Plan

Behavior of Gases: Disaster at Lake Nyos:

Students, through discussion and structured inquiry, will learn about the behavior of gases under various conditions. Students will be able to apply these concepts to everyday objects such as soda bottles, fire extinguishers, hot air balloons, propane tanks, and aerosol products.

Type: Lesson Plan

Shake it up:

Students will model molecular motion with everyday materials (shaker bottles) then associate their model/actions to the phase transitions of water while graphing its heat curve from data collected during a structured inquiry lab.

  • Students can predict how changing a variable among pressure, volume, temperature and number influences other gas properties.
  • Students can predict how changing temperature will affect the speed of molecules.
  • Students can rank the speed of molecules in thermal equilibrium based on the relative masses of molecules.
