8th Science
The student knows and applies scientific concepts and principles to understand the properties, structure, and changes in physical, earth/space, and living systems.
Understand how properties are used to identify, describe, and categorize substances, materials, and objects and how characteristics are used to categorize living things.
Grade Level Expectation: PR01 1.1.1 Properties of Substances (continued)
For changes in the state of matter, go to CH03 Conservation of Matter and Energy
Grades 6-8
Understand how to use physical and chemical properties to sort and identify substances.
Evidence of Learning
WASL and Classroom:
Given a description of an appropriate system, items may ask students to:
a) Identify, categorize, or describe substances using physical and/or chemical properties (i.e. boiling point, density, freezing point, mass, acidity (pH), magnetism, and solubility).
b) Identify an unknown substance using properties of known substances.
c) Identify or describe how the mass of an object is the same when measured anywhere in the universe at any normal speed.
d) Identify or describe why substances with the same volume or same mass may have different densities.
e) Identify or describe the volumetric properties of solids, liquids, and gases (e.g. a gas has the same volume as its container).
Grade Level Expectation: PR02 1.1.2 Motion of Objects
Grades 6-8
Understand the positions, relative speeds, and changes in speed of objects.
Evidence of Learning
WASL and Classroom:
Given a description of an appropriate system, items may ask students to:
a) Identify or describe the relative position or change in position of one or two objects.
b) Identify or describe an object’s motion as speeding up, slowing down, or moving with constant speed using models, numbers, words, diagrams, or graphs.
c) Identify or describe the speed of an object relative to the speed of another object.
Classroom:
· Measure the relative position or change in position of one or two objects.
· Measure the speed of an object relative to the speed of another object.
Grade Level Expectation: PR03 1.1.3 Wave Behavior
Grades 6-8
Understand sound waves, water waves, and light waves, using wave properties including amplitude, wavelength, and speed. Understand wave behaviors including reflection, refraction, transmission, and absorption.
Evidence of Learning
WASL and Classroom:
Given a description of an appropriate system, items may ask students to:
a) Identify or describe how sound waves and/or water waves affect the motion of the particles in the substance through which the wave is traveling (e.g. air molecules vibrate back and forth as sound waves move through air).
b) Identify or describe how the observed properties of light, sound, and water are related to amplitude, frequency, wavelength, and speed of waves (e.g. color and brightness of light, pitch and volume of sound, height of water waves, light waves are faster than sound waves).
c) Identify or describe the behavior of light waves when light interacts with transparent, translucent, and opaque substances (e.g. objects appear the color blue because the object reflects mostly blue light and absorbs all the other colors of light, transparent objects transmit most light through them, lenses refract light).
d) Identify or describe the behavior of sound waves and/or water waves as the waves are reflected and/or absorbed by a substance.
e) Identify or describe the changes in speed and/or direction as a wave goes from one substance into another.
Grade Level Expectation: PR04 1.1.4 Forms of Energy
For changes in energy, go to ST02 Energy Transfer and Transformation
Grades 6-8
Understand that energy is a property of matter, objects, and systems and comes in many forms.
Evidence of Learning
WASL and Classroom:
Given a description of an appropriate system, items may ask students to:
a) Identify or describe the form(s) of energy present in some matter (substance), an object, or a system (i.e. heat energy, sound energy, light energy, electrical energy, kinetic energy, potential energy, and chemical energy).
b) Identify or describe the form of energy stored in a part of a system (i.e. energy can be stored in many forms; ‘stored energy’ is not a form of energy).
c) Compare the potential and/or kinetic energy of parts of the system at various locations or times (i.e. kinetic energy is an object’s energy of motion, potential energy is an object’s energy of position).
Note: Heat energy is not light energy. Sunlight is does not have heat energy because sunlight has no matter; sunlight is not hot. Light energy from the Sun or any other source must be transformed into the heat energy of a substance to have a temperature or be ‘hot.’
Grade Level Expectation: PR05 1.1.5 Nature and Properties of Earth
Materials
For the weather effect of the water cycle go to CH06 Hydrosphere and Atmosphere
For identifying water’s state of matter, go to PR01 Properties of Substances
For water changing state, go to CH03 Conservation of Matter and Energy
Grades 6-8
Understand how to classify rocks, soils, air, and water into groups based on their chemical and physical properties.
Evidence of Learning
WASL and Classroom:
Given a description of an appropriate system, items may ask students to:
a) Identify or describe the properties of minerals and rocks that give evidence of how they were formed (e.g. crystal size and arrangement, texture, luster, cleavage, hardness, layering, reaction to acid).
b) Identify or describe the properties of soils that give evidence of how the soils were formed (e.g. chemical composition, particle type and size, organic materials, layering).
c) Identify or describe how Earth’s water (i.e. oceans, fresh waters, glaciers, ground water) can have different properties (i.e. salinity, density).
d) Identify or describe how the atmosphere has different properties at different elevations.
Grade Level Expectation: PR06 1.1.6 Characteristics of Living Matter
Grades 6-8
Understand how to classify organisms into groups by their external and internal structures.
Evidence of Learning
WASL and Classroom:
Given a description of an appropriate system, items may ask students to:
a) Identify or describe how organisms can be classified using similarities and differences in physical and functional characteristics (both internal and external).
b) Identify, describe, or explain an inference about whether organisms have a biological relationship or common ancestry based on given characteristics.
