Life Science Program Guide ~2014-2015

7th Grade Life ScienceProgram Guide
2014-2015
Welcome to 7th grade Life Science! The purpose of this document is to guide your daily lesson planning. It details the learning standards and targets of this course, the sequencing of the lessons and learning standards, opportunities for formative and summative assessment, district-approved resources, and strategies for differentiation.
How to Use this Document (Tutorial)
Features of this Program Guide:
Power Standards are referenced in Green and Complementary Standards are referenced in Yellow
The program guide is designed to be implemented following a 5E model. In general, elicit student thinking and background knowledge and engage them in thinking about the concept. Students should have time to explore the big ideas for the unit and then explain the concept or phenomena at hand. Student understanding can be extended, or additional concepts explored. Finally, student understanding is evaluated through formative and/or summative assessment. (For more information)
Assessments and Student Evidence listed are not an exhaustive list, however all students should engage in these fundamental activities. Pieces of the student text are specifically listed when the text is necessary for student explanations and deeper exploration.
The district summative assessments are sequenced into the Program Guide. The dates listed are not required dates for assessment, but are intended to be landmarks through the program guide to assist in planning and pacing. Assessments should be administered during the window referenced.
2014-15 is Year 2 of the transition into Next Generation Science Standards. Science & Engineering practices should guide the investigative work in which students are engaged and teachers should become familiar with the architecture and instructional shifts of the NGSS. Instructional leads will provide support and PD for this transition.
There are four units of study within Life Science, that are detailed in this Program Guide: Ecosystems & Living Things, Cells & Heredity, Evolution & Diversity, Human Body Systems
Ecosystems and Living Things
Ecosystems are complex, interactive systems that include both biological communities (biotic) and physical (abiotic) components of the environment. Ecosystems are dynamic, experiencing shifts in population composition and abundance and changes in the physical environment over time, which ultimately affects the stability and resilience of the entire system. (NGSS Framework, p. 150)
Content Goals:
Students apply their understanding of inquiry and designing controlled investigations and field studies.
Students develop an operational definition of a system and apply it in several contexts.
Students describe characteristics of living things and non-living components of living systems.
Students explain the interaction of living and non-living components of ecosystems. / Essential Questions:
How can I use data to communicate results of an investigation?
When is it helpful to define a system? How can system boundaries change?
How are living things organized?
In what ways are non-living components important in living systems?
What is an ecosystem?
How do living and non-living things interact in an ecosystem?

Note: Students can explore the scientific practices and cross-cutting concepts through this system. The Systems sub-unit can be used here or can be implemented later, at the beginning of the Ecosystems sub-unit.
Note: This investigation is meant to be a formative assessment, in which students demonstrate what they know coming into your classroom. Students’ work should inform lessons that will be needed as these skills come up later in the curriculum.
Note: Consider including a mini-lesson on linear measurement to ensure that students are able to collect accurate measurement data

Classifying Living Things

The curricular sequence was adjusted to begin with the idea of what makes something living and how all living things are organized.

Then students will move into the interaction between living and non-living aspects of ecosystems.

LS1A All organisms are composed of cells which carry on the many functions needed to sustain life
LS2D Ecosystems are continuously changing. Causes of these changes include non-living factors such as the amount of light, range of temperatures, and availability of water, as well as living factors such as the disappearance of different species through disease, predation, habitat

Note: Multiple standards are listed as this is an introductory section. Students are not expected to develop understanding at this point. It is easy to go into too much depth in this section.
CPO Investigations
Note: Emphasize writing questions
Note: Rather than using shoes, students can classify their binders, pasta or anything similar
Note: Investigation 3B may require modeling to help students understand the thought process behind dichotomous keys.

Living Systems
LS1A All organisms are composed of cells which carry on the many functions needed to sustain life
LS1C Multicellular organisms have specialized cells that perform different functions. These cells join together to form tissues that give organs their structure and enable the organs to perform specialized functions within organ systems.
INQG Scientific Reports should enable another investigator to repeat the study to check the results
SYSB The boundaries of a system can be drawn differently depending on the features of the system being investigated, the size of the system, and the purpose of the investigation.

CPO Investigations
Note: Set up the Investigation 2A or 2B, move into Investigation 4A and then return for observations and conclusions
Note: Consider germinating clover seeds on a cotton ball in order to make observations more easily in a smaller system
Note: Investigation 4A is included here because it links the requirement for energy to living things. This will flow into ecosystems.
Note: Jen Chase has Vernier probeware that can be borrowed for Cell Respiration
Note: Students with a shell fish allergy may have a reaction to the brine shrimp.
Note: Students learn to use a microscope in order to look at Brine Shrimp. If you are not using the Brine Shrimp investigation, consider moving the microscope lessons to accompany Cells.
Note: Investigation 2B, the salt concentration table is confusing. Create a data table based on amount of saltinstead of concentration. Students do not need to do these calculations to understand the investigation.
Note: Seeds can also be germinated in a paper towel & petri dish in order to speed up the investigation
Note: The emphasis for this section should be on understanding living systems
Note: Red Cabbage Indicator can be used in place of BTB with students

Note: A field study asks about the relationship between two variables that are generally not manipulated, or controlled, by the researcher.
Note: Students need to practice writing questions for field studies and understand this as a valid investigation.

Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principal.
Content Goals:
Students examine cells microscopically and analyze similarities and differences.
Students can describe relationships between structure and function within different types of cells.
Students distinguish between plant cells and animal cells.
Students explore hereditability by analyzing traits passed from one generation to another. This understanding is applied to the use of Punnett Squares to predict heredity. / Essential Questions:
What are the differences in the structure and function of plant and animal cells?
How do we use models to study living systems?
