SC.8.STM: Structure and Transformation of Matter (Physical Science)

SC.8.STM.U: Enduring Knowledge ? Understandings

SC.8.STM.U.1: all matter is made of tiny moving particles called atoms, which are far too small to see directly through a microscope. The atoms of any element are alike but are different from atoms of other elements.

 Element Builder

SC.8.STM.U.3: elements do not break down during chemical reactions (e.g., heating, exposure to electric currents, reaction with acids).

 Chemical Equations

SC.8.STM.U.4: the idea of atoms explains the conservation of matter: If the number of atoms stays the same no matter how they are rearranged, then their total mass stays the same. The atoms that are present today are the same atoms that have always existed.

 Chemical Changes
 Chemical Equations

SC.8.STM.S: Skills and Concepts

SC.8.STM.S.1: classify substances by how they react in given situations

 Mineral Identification

SC.8.STM.S.2: analyze models/representations of elements and basic atomic structure

 Element Builder

SC.8.STM.S.3: describe and illustrate the movement of elements between organisms and their physical environment and within the Earth system

 Cell Energy Cycle

SC.8.STM.S.4: analyze factors that may influence the movement of elements among the solid Earth, oceans, atmosphere and organisms

 Cell Energy Cycle

SC.8.STM.S.5: investigate the relationship between the seemingly indestructible nature of the atom and the concept of conservation of matter

 Chemical Changes
 Chemical Equations

SC.8.MF.U.2: preconceived expectations can influence what people actually observe, preventing them from detecting other results. In order to maintain objectivity, different investigators should investigate the same question independently. For example, Newton?s Laws are widely accepted because they have been verified by so many different observers.

 Effect of Temperature on Gender
 Growing Plants
 Seed Germination

SC.8.EU.S.2: identify a variety of landforms on the Earth?s surface that have undergone changes (both fast and slow) and investigate the forces responsible for those changes

 Rock Cycle

SC.8.UD.U.1: all cells contain specialized parts that are structured to efficiently perform the cell?s essential functions.

 Cell Structure
 Paramecium Homeostasis
 RNA and Protein Synthesis

SC.8.UD.U.3: organisms have nervous systems that allow them to react to changes in their surroundings and within themselves. Some of their reactions (e.g. pain response) are determined genetically while others (e.g. pushing a button to obtain food) are learned.

 Human Homeostasis

SC.8.UD.U.4: patterns (e.g. reproductive method, number of body segments, type of skeleton) are helpful in classifying organisms based on how they are related. Science considers details of internal and external structures to be more important than behavior or general appearance.

 Dichotomous Keys

SC.8.UD.S.1: investigate, model and explain the functions of the specialized parts within the cell

 Cell Structure
 Paramecium Homeostasis
 RNA and Protein Synthesis

SC.8.UD.S.3: investigate how the nervous systems of various organisms allow them to react (e.g. vomiting, avoidance) to internal (e.g., food toxins) and external (e.g., predator encounter) stimuli

 Human Homeostasis

SC.8.UD.S.4: describe the role of genes/chromosomes in the passing of information from one generation to another (heredity)

 Human Karyotyping

SC.8.BC.S.3: research the most common fossils used to support theories of biological change

 Human Evolution - Skull Analysis

SC.8.ET.U.1: energy can be transferred in many ways, but it can neither be created nor destroyed.

 2D Collisions
 Air Track
 Energy Conversion in a System

SC.8.ET.U.6: changes that occur to any one component of an ecosystem may influence the entire system, since all of the components are interrelated. The relationships that exist can be determined by observing the flow of energy.

 Food Chain

SC.8.ET.S.1: explain the law of conservation of energy and infer where energy goes in a number of real-life energy transformations

 Energy Conversion in a System
 Inclined Plane - Sliding Objects

SC.8.ET.S.2: identify the energy transformations that occur in the ?production?, transmission and use of energy by people in everyday life (e.g., electric power, automotive fuels, food)

 Food Chain
 Prairie Ecosystem
 Rabbit Population by Season

SC.8.I.U.2: the matter in an ecosystem is constantly transferred between and among organisms and the physical environment. While the form and location is continuously changing, the total amount of matter in the system remains constant.

 Cell Energy Cycle

SC.8.I.S.3: model the flow of energy and transfer of matter within ecosystems, communities and niches

 Carbon Cycle
