Course Description
Introduction
Science is a way of knowing, a process for gaining knowledge and understanding
of the natural world. The Science Core Curriculum places emphasis on understanding
and using skills. Students should be active learners. It is not enough for students
to read about science; they must do science. They should observe, inquire, question,
formulate and test hypotheses, analyze data, report, and evaluate findings.
The students, as scientists, should have hands-on, active experiences throughout
the instruction of the science curriculum.
The Science Core describes what students should know and be able to do at the
end of each course. It was developed, critiqued, piloted, and revised by a community
of Utah science teachers, university science educators, State Office of Education
specialists, scientists, expert national consultants, and an advisory committee
representing a wide diversity of people from the community. The Core reflects
the current philosophy of science education that is expressed in national documents
developed by the American Association for the Advancement of Science and the
National Academies of Science. This Science Core has the endorsement of the
Utah Science Teachers Association. The Core reflects high standards of achievement
in science for all students.
Organization of the Science Core
The Core is designed to help teachers organize and deliver instruction. Elements
of the Core include the following:
- Each grade level begins with a brief course description.
- The INTENDED LEARNING OUTCOMES (ILOs) describe the goals for science skills
and attitudes. They are found at the beginning of each grade, and are an integral
part of the Core that should be included as part of instruction.
- The SCIENCE BENCHMARKS describe the science content students should know.
Each grade level has three to five Science Benchmarks. The ILOs and Benchmarks
intersect in the Standards, Objectives and Indicators.
- A STANDARD is a broad statement of what students are expected to understand.
Several Objectives are listed under each Standard.
- An OBJECTIVE is a more focused description of what students need to know
and be able to do at the completion of instruction. If students have mastered
the Objectives associated with a given Standard, they are judged to have mastered
that Standard at that grade level. Several Indicators are described for each
Objective.
- An INDICATOR is a measurable or observable student action that enables one
to judge whether a student has mastered a particular Objective. Indicators
are not meant to be classroom activities, but they can help guide classroom
instruction.
- SCIENCE LANGUAGE STUDENTS SHOULD USE is a list of terms that students and
teachers should integrate into their normal daily conversations around science
topics. These are not vocabulary lists for students to memorize.
Seven Guidelines Were Used in Developing the Science Core
Reflects the Nature of Science: Science is a way
of knowing, a process for gaining knowledge and understanding of the natural
world. The Core is designed to produce an integrated set of Intended Learning
Outcomes (ILOs) for students.
As described in these ILOs, students will:
- Use science process and thinking skills.
- Manifest science interests and attitudes.
- Understand important science concepts and principles.
- Communicate effectively using science language and reasoning.
- Demonstrate awareness of the social and historical aspects of science.
- Understand the nature of science.
Coherent: The Core has been designed so that, wherever
possible, the science ideas taught within a particular grade level have a logical
and natural connection with each other and with those of earlier grades. Efforts
have also been made to select topics and skills that integrate well with one
another and with other subject areas appropriate to grade level. In addition,
there is an upward articulation of science concepts, skills, and content. This
spiraling is intended to prepare students to understand and use more complex
science concepts and skills as they advance through their science learning.
Developmentally Appropriate: The Core takes into
account the psychological and social readiness of students. It builds from concrete
experiences to more abstract understandings. The Core describes science language
students should use that is appropriate to their grade level. A more extensive
vocabulary should not be emphasized. In the past, many educators may have mistakenly
thought that students understood abstract concepts (such as the nature of the
atom) because they repeated appropriate names and vocabulary (such as "electron"
and "neutron"). The Core resists the temptation to describe abstract
concepts at inappropriate grade levels; rather, it focuses on providing experiences
with concepts that students can explore and understand in depth to build a foundation
for future science learning.
Encourages Good Teaching Practices: It is impossible
to accomplish the full intent of the Core by lecturing and having students read
from textbooks. The Science Core emphasizes student inquiry. Science process
skills are central in each standard. Good science encourages students to gain
knowledge by doing science: observing, questioning, exploring, making and testing
hypotheses, comparing predictions, evaluating data, and communicating conclusions.
The Core is designed to encourage instruction with students working in cooperative
groups. Instruction should connect lessons with students' daily lives.
The Core directs experiential science instruction for all students, not just
those who have traditionally succeeded in science classes.
Comprehensive: The Science Core does not cover all
topics that have traditionally been in the science curriculum; however, it does
provide a comprehensive background in science. By emphasizing depth rather than
breadth, the Core seeks to empower students rather than intimidate them with
a collection of isolated and forgettable facts. Teachers are free to add related
concepts and skills, but they are expected to teach all the standards and objectives
specified in the Core for their grade level.
Useful and Relevant: This curriculum relates directly
to student needs and interests. It is grounded in the natural world in which
we live. Relevance of science to other endeavors enables students to transfer
skills gained from science instruction into their other school subjects and
into their lives outside the classroom.
Encourages Good Assessment Practices: Student achievement
of the standards and objectives in this Core is best assessed using a variety
of assessment instruments. The purpose of an assessment should be clear to the
teacher as it is planned, implemented, and evaluated. Performance tests are
particularly appropriate to evaluate student mastery of science processes and
problem-solving skills. Teachers should use a variety of classroom assessment
approaches in conjunction with standard assessment instruments to inform their
instruction. Observation of students engaged in science activities
is highly recommended as a way to assess students' skills as well as attitudes
in science. The nature of the questions posed by students provides important
evidence of students' understanding of and interest in science.
Intended Learning Outcomes for Seventh and Eighth Grade Integrated
Science
The Intended Learning Outcomes (ILOs) describe the skills and attitudes students
should learn and demonstrate as a result of science instruction. They are an
essential part of the Science Core Curriculum and provide teachers with a standard
for evaluation of student learning in science. Instruction should include significant
science experiences that lead to student understanding using the ILOs.
The main intent of science instruction in Utah is that students
will value and use science as a process of obtaining knowledge based upon observable
evidence.
By the end of seventh and eight grades students will be able to:
- Use Science Process and Thinking Skills
- Observe objects and events for patterns and record both qualitative
and quantitative information.
- Sort and sequence data according to a given criterion.
- Develop and use categories to classify subjects studied.
- Select the appropriate instrument; measure, calculate, and record in
metric units, length, volume, temperature and mass, to the accuracy of
instruments used.
- When given a problem, plan and conduct experiments in which they:
- Form research questions.
- Discuss possible outcomes of investigations.
- Identify variables.
- Plan procedures to control independent variable(s).
- Collect data on the dependent variable(s).
- Select appropriate format (e.g., graph, chart, diagram) to summarize
data obtained.
- Analyze data and construct reasonable conclusions.
- Prepare written and oral reports of their investigation.
- Distinguish between factual statements and inferences.
- Use field guides or other keys to assist in the identification of subjects
studied.
- Manifest Scientific Attitudes and Interests
- Read and look at books and other science materials voluntarily.
- Raise questions about objects, events, and processes that can be answered
through scientific investigation.
- Maintain an open and questioning mind toward ideas and alternative
points of view.
- Check reports of observations for accuracy.
- Accept and use scientific evidence to help resolve ecological problems.
- Demonstrate Understanding of Science Concepts and Principles
- Know and explain science information specified for their grade level.

been taught.
- Compare concepts and principles based upon specific criteria.
- Solve problems appropriate to grade level by applying scientific principles
and procedures.
- Communicate Effectively Using Science Language and Reasoning
- Provide relevant data to support their inferences and conclusions.
- Use precise scientific language in oral and written communication.
- Use correct English in oral and written reports.
- Use reference sources to obtain information and cite the sources.
- Use mathematical reasoning to communicate information.
- Construct models to describe concepts and principles.
- Demonstrate Awareness of Social and Historical Aspects
of Science
- Cite examples of how science affects life.
- Give instances of how technological advances have influenced the progress
of science and how science has influenced advances in technology.
- Understand the cumulative nature of the development of science knowledge.
- Recognize contributions to science knowledge that have been made by
both men and women.
- Demonstrate Understanding of the Nature of Science
- Science is a way of knowing that is used by many people, not just scientists.
- Understand that science investigations use a variety of methods and
do not always use the same set of procedures; understand that there is
not just one "scientific method."
- Science findings are based upon evidence.
- Understand that science conclusions are tentative and therefore never
final. Understandings based upon these conclusions are subject to revision
in light of new evidence.
- Understand that scientific conclusions are based on the assumption that
natural laws operate today as they did in the past and that they will
continue to do so in the future.
- Understand that various disciplines of science are interrelated and
share common rules of evidence to explain phenomena in the natural world.

Seventh Grade Integrated Science Core Curriculum
Physical, earth, and life science content are integrated in a curriculum with
two primary goals: (1) students will value and use science as a process of obtaining
knowledge based on observable evidence, and (2) students' curiosity will
be sustained as they develop the abilities associated with scientific inquiry.
Theme
The theme for Seventh Grade Science is structure.
The concept of density is used to help understand the sorting and distribution
of matter on Earth. Seventh graders should begin to relate the structure of
matter to the properties of materials. The "Benchmarks" in the seventh
grade Core emphasize "structure" as an organizing concept to understand
matter. All substances are made of smaller parts and are themselves parts of
larger wholes. When parts come together, the whole often has properties that
are very different from its parts. Inherited traits are carried on structures
called genes. Structure is used to classify plants, animals, rocks, stars, and
other things. Classification is a way to give a unique description to all things.
Inquiry
Seventh grade students should design and perform experiments, and value inquiry
as the fundamental scientific process. They should be encouraged to maintain
an open and questioning mind to pose their own questions about objects, events,
processes, and results. They should have the opportunity to plan and conduct
their own experiments, and come to their own conclusions as they read, observe,
compare, describe, infer, and draw conclusions. The results of their experiments
need to be compared for reasonableness to multiple sources of information. It
is important for students at this age to begin to formalize the processes of
science and be able to identify the variables in a formal experiment.
Good science instruction requires hands-on science investigations in which
student inquiry is an important goal. Teachers should provide opportunities
for all students to experience many things. Seventh
graders should investigate living organisms at the cellular level through firsthand
observations. Students can find excitement through identifying things such as
insects, plants, and rocks by using field guides. Students should enjoy science
as a process of discovering the natural world.
Relevance
Seventh grade core concepts should be integrated with concepts and skills from
other curriculum areas. Reading, writing, and mathematics skills should be emphasized
as integral to the instruction of science. Personal relevance of science in
students' lives is an important part of helping students to value science
and should be emphasized at this grade level. Developing students' writing skills
in science should be an important part of science instruction in the seventh
grade. Students should regularly write descriptions of their observations and
experiments. Lab journals are an effective way to emphasize the importance of
writing in science.
Providing opportunities for students to gain insights into science related
careers adds to the relevance of science learning. Some of the Seventh Grade
Science Core objectives expose students to fundamental concepts of genetics;
this is an excellent opportunity for students to broaden their understanding
of careers in genetics.
Character
Value for honesty, integrity, self-discipline, respect, responsibility, punctuality,
dependability, courtesy, co-operation, consideration, and teamwork should be
emphasized as an integral part of science learning. These relate to the care
of living things, safety and concern for self and others, and environmental
stewardship. Honesty in all aspects of research, experimentation, data collection,
and reporting is an essential component of science.
Resources for Instruction
This Core was designed using the American Association for the Advancement of
Science's Project 2061: Benchmarks For Science Literacy and the
National Academy of Sciences' National Science Education Standards
as guides to determine appropriate content and skills.
The Seventh Grade Integrated Science Core has online resources called Sci-ber
Text, an electronic science textbook; web resources listed by Core objective
Safety Precautions
The hands-on nature of science learning increases the need for teachers to use
appropriate precautions in the classroom and field. Proper handling and disposal
of chemicals and microorganisms is crucial for a safe classroom.
Appropriate Use of Living Things in the Science Classroom
It is important to maintain a safe, humane environment for animals in the classroom.
Field activities should be well thought out and use appropriate and safe practices.
Student collections should be done under the guidance of the teacher with attention
to the impact on the environment. The number and size of the samples taken for
the collections should be considered in light of the educational benefit. Some
organisms should not be taken from the environment, but rather observed and
described using photographs, drawings, or written descriptions to be included
in the student's collection. Teachers must adhere to
the published guidelines for the proper use of living things, equipment,
and chemicals in the classroom. These guidelines are available on the Utah Science
Home Page.
The Most Important Goal
Science instruction should cultivate and build on students' curiosity
and sense of wonder. Effective science instruction engages students in enjoyable
learning experiences. Science instruction should be as thrilling an experience
for a student as opening a rock and seeing a fossil, watching the colors change
in a chemical reaction, or observing the consistent sequence of color in a rainbow.
Science is not just for those who have traditionally succeeded in the subject,
and it is not just for those who will choose science-related careers. In a world
of rapidly expanding knowledge and technology, all students must gain the skills
they will need to understand and function responsibly and successfully in the
world. The Core provides skills in a context that enables students to experience
the joy of doing science.
Core Standards of the Course
Science Benchmark All matter is made up of atoms that are far too small to see. Atoms are in perpetual motion and the more energy they contain the faster they move. Atoms combine to form molecules. Matter is made up of atoms and molecules that have measurable mass, volume, and density. Density is a measure of the compactness of matter. Density determines the way materials in a mixture are sorted. This property of matter results in the layering and structure of Earth’s atmosphere, water, crust, and interior.
Models are used to describe the structure of Earth.

Science Benchmark Living things are made of smaller structures whose functions enable the organisms to survive. The basic unit of structure in all living things is the cell. Cells combine to form tissues that combine to form organs. While all cells have common structures, there are differences between plant and animal cells. Cell details are usually visible only through a microscope.
Reproduction passes information from parent to offspring. Asexual reproduction requires one parent and produces nearly identical offspring. Sexual reproduction requires two parents, and provides variety in a species. This variety may allow the species to adapt to changes in the environment and help the species survive. A species may change due to the passing of traits naturally or by techniques used and developed by science. Genetic information is passed on in a predictable manner.
Standard 3
Students will understand that the organs in an organism are made of cells that have structures and perform specific life functions.

Language science students should use: acquired trait, asexual reproduction, genetics, nucleus, organ, organism, osmosis, system, tissue, inherited trait, offspring, sexual reproduction, cytoplasm, diffusion, membrane, chloroplast, cell, cell wall
Science Benchmark Classification schemes reflect orderly patterns and observable distinctions among objects and organisms. One of the most general distinctions among organisms is between plants and animals.
Biologists consider an organism's structural features more important for classifying organisms than behavior or general appearance. Geologists classify earth materials based upon structure. Chemists classify matter based upon structure. Classification systems may change as science develops new knowledge.
