TRANSCRIPT
Grade 7 Science - 2015, The Archdiocese of Cincinnati
GRADE 7 SCIENCE
The Archdiocese of Cincinnati has established the following Science standards based on the most
current teachings which are aligned to Ohio New Learning Science Standards. In addition, these
Standards are infused with Catholic Identity and Catholic values. This curriculum gives parents,
students, and teachers the knowledge, understanding, and skill set students need to acquire and satisfy
the Archdiocesan Science Standards for Grade 7.
SCIENCE APPLICATION
Grade 7 students are expected to meet each year’s grade-specific standards. Students retain and master skills
learned in the preceding grades, and will further develop their skills to gain exposure to a range of texts and
tasks. Rigor is infused throughout this Graded Course of Study (GCS) along with relevance to further foster
the values of Catholic teaching.
Science for Grade 7 is divided into four standards:
Science Inquiry and Application (SIA)
Earth and Space Science (ESS)
Life Science (LS)
Physical Science (PS)
SIA – Students in Grade 7 learn that learning Science requires inquiry. They learn that Scientific Inquiry is a
way of knowing and a process of doing science. They will acquire an understanding of scientific inquiry and
discover patterns, trends, structures, and relationships that may be described by simple principles. These
principles are related to the properties within and between systems. Scientific inquiry is enhanced through
activities in which students develop knowledge and understandings of scientific ideas as well as an
understanding of how scientists study the natural world that was of God’s design and creation.
ESS – Grade 7 students know that God is the Supreme Creator of Earth. Grade 7 students will focus on
Earth’s hydrologic cycle and patterns that exist in the atmospheric and oceanic currents. Students will also
focus on the relationship between thermal energy and the currents, as well as the relative position and
movement of the Earth’s sun and moon.
Students in Grades 5-8 must develop the ability in Earth and Space Science to:
1. Explain how the hydrologic cycle illustrates the changing states of water as it moves through the
lithosphere, biosphere, hydrosphere and atmosphere.
2. Analyze how thermal-energy transfers in the ocean and the atmosphere contribute to the formation of
currents, which influence global climate patterns.
3. Explain how the atmosphere has different properties at different elevations and contains a mixture of
gases that cycle through the lithosphere, biosphere, hydrosphere and atmosphere.
4. Summarize the relative patterns of motion and positions of the Earth, moon and sun cause solar and
lunar eclipses, tides, and phases of the moon.
Grade 7 Science - 2015, The Archdiocese of Cincinnati
LS – Students focus on the impact of matter and energy transferred within the biotic component of the
ecosystem.
Students in Grade 5-8 must develop the ability in Life Science to:
1. Analyze and explain the continuous transfer of matter between one organism to another, and between
organisms and their physical environments.
2. Explain why in any particular biome, the number, growth, and survival of organisms and populations
depend on biotic and abiotic factors.
PS – Students study the empirical evidence for the arrangements of atoms on the Periodic Table of Elements.
The conservation of mass and energy, and transformation and transfer of energy is also learned.
Students in Grades 5-8 must develop the ability in Physical Science to:
1. Determine the properties of matter by the arrangement of atoms.
2. Explain how energy can be transformed or transferred but is never lost.
3. Analyze how energy can be transferred through a variety of ways.
SUMMARY – SCIENCE GRADE 7
All 7th
grade students know that all forms of life on earth were created by God. 7th grade Science Standards
offer focus for instruction throughout the school year to ensure adequate exposure to a range of texts, tasks,
and application, and to give students ample knowledge and skills to be prepared for the next level of science.
In addition 7th
grade Science standards can be connected to The Catechism of the Catholic Church for
reference for topics, issues, and/or questions that may arise in Science class. The following may be used:

Grade 7 Science - 2015, The Archdiocese of Cincinnati
Inquiry Based Science One of the biggest differences between this Graded Course of Study (GCS) and previous Science Graded
Courses of Study (GCS) is the focus on inquiry based learning. Inquiry based learning is based on the philosophy of
constructivist learning. That is the idea that students must be able to create their own understanding of concepts.
There are several levels to inquiry based learning. These range from no inquiry to open inquiry.
When there is no inquiry, teachers tell the students the facts and expected to repeat these facts to prove their
knowledge. In open inquiry, students are given the materials to learn. The students are expected to create their
own knowledge. This will lead them to a greater understanding and long-term retention of the material.
Think of a time when you learned something new or wanted to understand something in greater depth. It
is rare that the learning process is a linear one. Often, you will be intrigued by something you see. Imagine trying to
figure out why ice melts in the sun. In trying to understand this, you make judgments based on both previous
knowledge and personal experiences. You begin to inquire about why does this happen. You explore and this
becomes less of a mystery. Through this process, you know that the sun and melting ice fit together, but you are
not exactly sure how that happens. Sometimes, it does not fit together nicely and old ideas must be broken down
and reconstructed. (The ice still melted at night; why?) It is through these experiences that understandings are
extended. An idea is tested and if it does not work, we go back and retest it. If we go back to the ice example, you
realize that the ice will melt on a warm night just as it will during a warm day. You realize that it is not the sun by
itself that melts the ice. Instead, it is the heat that causes ice to melt.
Though this entire process, you have gained much more knowledge than heat causes matter to change
form. You have learned how to take your previous knowledge and apply it in a specific situation. You have made
observations, tested your ideas, reflected on what did not work, and gathered additional information. Learning is
not a linear process. Learning is a continuous and individual process. As a student, you facilitated your own
learning. This is exactly what inquiry based learning is. It is taking old skills and knowledge and applying them in
new situations. It is learning by doing.
No Inquiry
•The teacher lectures to the class about electricity and circuits.
Direct Inquiry
•The teacher has the students follow a step- by-step lab to create a circuit and light a bulb.
Guided Inquiry
•The teacher gives the students wire, batteries, and a light bulb. The students are told to create a circuit to light the bulb.
Open Inquiry
•The teacher gives the students wire, batteries, and a light bulb. The students are left to create something on their own.
Grade 7 Science - 2015, The Archdiocese of Cincinnati
The teacher still has a very important role in all of this. While students are naturally curious about the world
around them, it is still important for the teacher to lay the groundwork for the class. A question or a problem can
get the students engaged in the instructional task. If we think about marketing, a company needs your attention
before you will buy their product. It does not matter if it is the best product in the world. If you do not know it
exists, you will not purchase it.
When students explore, they are directly involved with the material. This is where they develop the
experiences to build their knowledge. The classroom teacher is necessary at this point to provide the materials
and guided focus.
After the students have completed their explorations, it is time for them to explain what they have
learned. During the explanation process, teachers have a vital role of correcting misconceptions or introducing
formal vocabulary. A student who learned that a ball will continue rolling until friction and gravity act upon it will
have something concrete to think of when Newton’s First Law of Motion is mentioned.
The teacher is also essential in elaboration of the topic. The teacher can raise questions that were not
brought up in the exploration stage. If the students were working with the laws of motion, they can be asked
about which balls will go further on a given surface. It is not possible to explore every situation, but the knowledge
the students gained during the exploration stage will help them in these areas.
Finally, there is the assessment piece. This should be an on-going piece throughout this entire process.
This will allow the teacher to determine whether the student understands the material. Some tools to help you
with this are rubrics, observations, checklists, interviews, and portfolios. Assessment must guide future lesson
planning and may even be cause for modification in the future. For example, if you notice there is a misconception
with many students, you can revisit the concept. If you notice great student interest in a specific area, the class
can be refocused to take advantage of this high level of interest.
Archdiocese of Cincinnati Catholic School’s Office Philosophy of Assessment
Grade 7 Science - 2015, The Archdiocese of Cincinnati
Based on educational research, the following is a set of grading practices organized into guidelines. These
guidelines should provide a framework of effective grading practices. The goal is to support student learning
and encourage student success.
It is important to be aware that the qualities of any grading guidelines are directly dependent on the quality of
diagnostic, formative, and summative assessments used in the classroom. They are not meant to be so specific
when a teacher is not afforded flexibility in the classroom. Instead, these are suggestions and explanations of
grading techniques that have been proven to increase the level of student achievement.
Relate grades to the achievement based on the standards.
The Ohio New Learning Science Standards are aligned to the Archdiocesan Graded Course of Study. Standards are
the basis of determining grades. Specific learning targets should be used to figure grades.
Use performance standards as reference points when determining grades.
Whether symbols, letters, or numbers are used, the students’ scores should reflect whether or not the students
have mastered the standard.
Separate achievement from other non-academic items such as effort, behavior, and
participation.
Grades should only indicate what a student knows, understands, and can do. Effort, behavior, participation should
be reported separately from achievement. Individual achievement, not group achievement should be the basis for
the grade.
Sample student performance. Don’t score everything, and don’t include all scores in grades.
Everything does not need to be scored and include in a grade. Formative assessments are tools to guide future
instruction. You can assess these with rubrics, checklists, scoring guides and a variety of other methods. Scores at
the end of the grading period, after the learning has taken place, should be the determining factor when figuring
grades.
Use quality assessments and accurately record evidence of achievement.
Assessments should match what the student is expected to learn, this is called relevant learning. There are many
tools (e.g. portfolios, rubrics, interviews) other than the standard paper and pencil tests to assess a student’s
understanding of the material.
Discuss and involve students in the assessment and grading processes throughout the
learning cycle.
One method that has continued to increase student achievement is involving them in the assessment process.
Grade 7 Science - 2015, The Archdiocese of Cincinnati
Students should be involved in all steps of this process. At the most basic level, students can simply understand
how their grades will be determined. As assessment becomes more student- centered, the students can develop
rubrics, maintain their own assessment records, self- assess, and communicate their achievement to others
(student-led conferences).
Reading Standards for 7th Grade Science Key Ideas and Details: 1. Cite specific textual evidence to support analysis of science and technical texts. 2. Determine the central ideas or conclusions of a text; provide an accurate summary of the text
distinct from prior knowledge or opinions.
Grade 7 Science - 2015, The Archdiocese of Cincinnati
3. Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
Craft and Structure: 4. Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they
are used in a specific scientific or technical context relevant to grades 6-8 texts and topics. 5. Analyze the structure an author uses to organize a text, including how the major sections contribute
to the whole and to an understanding of the topic. 6. Analyze the author’s purpose in providing an explanation, describing a procedure, or discussing an
experiment in a text. Integration of Knowledge and Ideas: 7. Integrate quantitative or technical information expressed in words in a text with a version of that
information expressed visually (e.g., in a flowchart, diagram, model, graph, or table). 8. Distinguish among facts, reasoned judgment based on research findings, and speculation in a text. 9. Compare and contrast the information gained from experiments, simulations, video or multimedia
sources with that gained from reading a text on the same topic. Range of Reading and Level of Text Complexity: 10. By the end of grade 8, read and comprehend science/technical texts in the grades 6-8 text
complexity band independently and proficiently.
Writing Standard for 7th Grade Science Text Types and Purposes: 1. Write arguments focused on discipline-specific content. a. Introduce claim(s) about a topic or issue, acknowledge and distinguish the claim(s) from alternate
or opposing claims, and organize the reasons and evidence logically. b. Support claim(s) with logical reasoning and relevant, accurate data and evidence that
demonstrate an understanding of the topic or text, using credible sources. c. Use words, phrases, and clauses to create cohesion and clarify the relationships among claim(s),
counterclaims, reasons, and evidence. d. Establish and maintain a formal style. e. Provide a concluding statement or section that follows from and supports the argument
presented. 2. Write informative/explanatory texts, including the narration of historical events, scientific
procedures/experiments, or technical processes. a. Introduce a topic clearly, previewing what is to follow; organize ideas, concepts, and information
into broader categories as appropriate to achieving purpose; include formatting (e.g., headings), graphics (e.g., charts, tables), and multimedia when useful to aiding comprehension.
b. Develop the topic with relevant, well-chosen facts, definitions, concrete details, quotations, or other information and examples.
c. Use appropriate and varied transitions to create cohesion and clarify the relationships among ideas and concepts.
d. Use precise language and domain-specific vocabulary to inform about or explain the topic. e. Establish and maintain a formal style and objective tone. f. Provide a concluding statement or section that follows from and supports the information or
explanation presented.
Grade 7 Science - 2015, The Archdiocese of Cincinnati
3. Students’ narrative skills continue to grow in these grades. The Standards require that students be able to incorporate narrative elements effectively into arguments and informative/explanatory texts. In science and technical subjects, students must be able to write precise enough descriptions of the step-by-step procedures they use in their investigations or technical work that others can replicate them and (possibly) reach the same results.
Production and Distribution of Writing: 4. Produce clear and coherent writing in which the development, organization, and style are
appropriate to task, purpose, and audience. 5. With some guidance and support from peers and adults, develop and strengthen writing as needed
by planning, revising, editing, rewriting, or trying a new approach, focusing on how well purpose and audience have been addressed.
6. Use technology, including the Internet, to produce and publish writing and present the relationships between information and ideas clearly and efficiently.
Research to Build and Present Knowledge: 7. Conduct short research projects to answer a question (including a self-generated question), drawing
on several sources and generating additional related, focused questions that allow for multiple avenues of exploration.
8. Gather relevant information from multiple print and digital sources, using search terms effectively; assess the credibility and accuracy of each source; and quote or paraphrase the data and conclusions of others while avoiding plagiarism and following a standard format for citation.
9. Draw evidence from informational texts to support analysis, reflection, and research. Range of Writing: 10. Write routinely over extended time frames (time for reflection and revision) and shorter time frames
(a single sitting or a day or two) for a range of discipline-specific tasks, purposes, and audiences.
