  • 1. 8th 8th Grade Science Curriculum Map IntroductionThis document contains all mandated Arizona state standards for 8th grade science. The standards have been organized into units and clusters. Theunits represent the major domain or field of scientific study under which the identified standards fall. The cluster represents the collection of similarconcepts within the larger domain. Within these units and clusters the performance objectives have been sequenced to represent a logical progressionof the content knowledge. It is expected that all teachers follow the sequence of units and clusters as described in the following document. OrganizationApproximate TimeApproximate times are based on a 60-minute instructional session for grades 6-8 and a 30-minute instructional session for grades 4 and 5. Allunits and clusters must be taught prior to the third quarter benchmark assessments.Essential QuestionsEssential Questions are to be posed to the students at the beginning of the cluster and revisited throughout the cluster. They are designed to facilitateconceptual development of the content and can be used as a tool for making connections, higher order thinking and inquiry. The students should beable to answer these on their own by the end of the cluster.Big IdeasBig Ideas are the essential understandings that are critical for students’ learning. These are the enduring understandings we want students to carrywith them from grade level to grade level. Answering the Essential Questions is indicative of a student mastering the Big Idea, however they are notalways synonymous. Thus, in cases that the answer to the Essential Question does not include all components of the Big Idea, the Big Idea (for teacheruse) has been provided in italics.Common MisconceptionsThese are common misunderstandings students bring to the learning process. Being aware of such misconceptions allows us to plan for them duringinstruction.Content and Skill/Process StandardsThis document has been organized by content standards and skill or process standard. The content standards are those that represent knowledgespecific to the scientific domain outlined in the unit (strands 4-6). The skill/process standards represent the skills involved in scientific inquiry, scientifichabits of mind and/or scientific advancements and opportunities (strands 1-3). The content and skill/process standards have been paired to representpossible combinations of performance objectives from strands 1-3 with performance objectives from strands 4-6. As described in the Arizona statestandards, strands 1-3 are not intended to be taught in isolation; thus, the pairing of these performance objectives provides a possible context forteaching these performance objectives. Each time, the performance objective should be taught to a deeper level of understanding and/or should beconnected to the other performance objectives in the cluster.8/13/2012 1 Isaac Elementary School District
  • 2. 8thCommon Core/Cross CurricularThe standards in the Common Core/Cross Curricular column represent possible reading, writing, math and language standards that can be reinforcedor taught through the science standards with which they are paired. These standards will be added as the Common Core curriculum is developed for4th-8th grade.PriorityWith input from grade level teachers, standards have been prioritized in two ways. The content standards have been prioritized using a three-pointscale. Essential standards represent those that are heavily weighted on state/national exams, foundational, and/or applicable in multiple contexts.Important standards are those that are applicable in many contexts and less heavily weighted on state/national exams. Useful standards are thosewith the least weight on state/national exams and are likely only useful in a specific scientific context. This is denoted in the priority column with thecodes E (essential), I (important) and U (useful). This label applies to the content standards only. The skill/process standards that are a priority forthis grade level are highlighted in blue and are expected to be mastered at this grade level.Key VocabularyThe key vocabulary that should be taught for each of the performance objectives is listed under key vocabulary. These vocabulary words are codedas tier one (1), tier two (2) or tier three (3). Tier one words are those that are very common and should not be explicitly taught. Tier two words arehigh utility words that can be used across content areas or contexts. Tier three words are content specific words.ResourcesThe two types of resources listed are the Lab/Activity resources and the Web/Core Resources. All are suggestions that teachers may use to supportinstruction. They are aligned to the performance objectives listed in the same row. The Web Resources are useful Internet links that can be used forthe teacher’s edification prior to instruction or as a tool during instruction. The core resources are suggested pages from the adopted texts. Similarly,the Lab/Activity resources are possible labs or activities that support the performance objectives with which they are paired.Unit/Cluster ProjectThe Unit/Cluster Projects are possible projects that teachers can use to support students in making connections, critical thinking, higher order thinking,and/or spiraling curriculum. Unit projects support standards from all clusters within a unit while cluster project support the standards in a particularcluster. While it is not required that a teacher do a project with every unit or cluster these resources will support project-based instruction andpractice should the teacher choose to implement them.AssessmentThe assessment section of the map has been left blank for teachers to plan the dates that they will give a formative assessment for the cluster. It isexpected that each cluster be assessed using a common formative assessment.OtherPerformance objectives may appear more than once. Each time they should be taught within the context of the cluster and/or revisited to a deeperlevel of knowledge. Underlined segments of a PO indicate an additional piece of the PO that was likely not covered in previous clusters. [Brackets]will occasionally appear though out the document and indicate clarification of the PO. Bracketed information is not a part of the PO itself.8/13/2012 2 Isaac Elementary School District

  • 4. 8th Essential Questions Big Ideas  All matter can be categorized into three groups. What are they and  Matter can be classified by its chemical and physical what is the difference between them? properties as well as its structural composition (element, compound, mixture). Matter can be classified as an element (a single type of atom), a compound (two or more elements chemically bonded together that cannot be separated by physical means) or a mixture (two or more elements or compounds that are in the same space but not bonded together and can be separated by physical means).  Mixtures can be heterogenous or homogeneous.  Milk purchased at most stores says, “pasteurized and homogenized.” What does that mean and why would we do it to our milk? Pasteruized and homogenized means that the milk has been processed to stay fresh longer and to prevent it from separating.  Matter has observable properties.  Suppose I were to find an unknown liquid in the classroom. What tests could I do to figure out what it is? To identify the unknown liquid we could, among other things, heat it to find its boiling point, cool it to find the freezing point, test the pH, and leave it at room temperature to find its common state. This data could be compared to charts with data for various known substances to identify the unknown substance.8/13/2012 4 Isaac Elementary School District

  • 10. 8th Essential Questions Big Ideas  Is it possible to have speed but no velocity?  Both speed and velocity can be measured. No. If something is moving it is moving in a given direction therefore, it will have speed and velocity. We can however, only choose to measure speed without the direction.  Velocity-time graphs and distance-time graphs show motion.  What does a flat line on a velocity-time graph mean? What does a flat line on a distance-time graph mean? On a velocity-time graph, a flat line represents a constant velocity but on a distance-time graph, the flat line represents no motion or an object at rest.

It is dangerous to drive on icy roads because even if they brake, the moving cars are likely to continue moving. The ice creates less friction between the wheels, giving the car more inertia, making it difficult to stop.  In football, the linemen are typically very big. Why are the biggest  Newton’s Second Law of Motion: the force required players usually the blockers? to accelerate an object is proportional to the mass of the object (F=m x a) The linemen are usually the biggest because they are there to protect the quarterback. They need to be very difficult to move so that other players cannot get to the quarterback and he has time to throw the ball.  Two children standing on skateboards face one another and push on  Newton’s Third Law of Motion: all forces occur in each other’s hands.

Both children will be pushed away from one another on their skateboards.  Newton’s Laws affect daily life in a variety of ways.  How have Newton’s Laws of Motion influenced daily human life? These laws are the basis for most engineering and evidence of them can be found everywhere. Door hinges, airbags, seatbelts, airplanes, trampolines, and helmets are just a few examples of how the Laws of Motion have influenced daily human life.8/13/2012 13 Isaac Elementary School District

  • 17. 8th Approximate Time: 7 days Essential Questions Big Ideas  How are mitosis and meiosis alike and different?  Both mitosis and meiosis are cell division but mitosis facilitates growth, development and repair while meiosis facilitates reproduction. Mitosis and meiosis are alike in that they are both forms of cell division. They are different in that mitosis produces two cells that are exact copies of one another while meiosis produces four cells that each only contains half a set of chromosomes.  What would occur if all mitosis stopped?  Mitosis produces exact copies of cells, allowing organisms to grow, develop and repair. If all mitosis stopped, organisms could not grow, develop or repair.  What would occur if all meiosis stopped?  Meiosis produces haploid cells that allow organisms to reproduce. If meiosis stopped, organisms could not reproduce.8/13/2012 17 Isaac Elementary School District

If this is the case there is a ¼ chance that the couple will have a child with Tay-Sach’s Disease.  Industrial chemical waste can cause genetic mutations. Genetic mutations in any given species can be dangerous to the balance of an ecosystem. Additionally, they can be dangerous to the entire species if the mutation is unfavorable and passed on to other generations. Everyone should be concerned with practices such as this for many reasons. First of all, the contaminants can enter the water system and spread to other communities. Second, the contaminants can cause genetic mutations in organisms in the environment. If mutations occur this will negatively affect the whole ecosystem.8/13/2012 19 Isaac Elementary School District
