General Course Information and Notes

General Notes

While the content focus of this course is consistent with the Biology I course, students will explore these concepts in greater depth. In general, the academic pace and rigor will be greatly increased for honors level course work. Laboratory investigations that include the use of scientific inquiry, research, measurement, problem solving, laboratory apparatus and technologies, experimental procedures, and safety procedures are an integral part of this course. The National Science Teachers Association (NSTA) recommends that at the high school level, all students should be in the science lab or field, collecting data every week. School laboratory investigations (labs) are defined by the National Research Council (NRC) as an experience in the laboratory, classroom, or the field that provides students with opportunities to interact directly with natural phenomena or with data collected by others using tools, materials, data collection techniques, and models (NRC, 2006, p. 3). Laboratory investigations in the high school classroom should help all students develop a growing understanding of the complexity and ambiguity of empirical work, as well as the skills to calibrate and troubleshoot equipment used to make observations. Learners should understand measurement error; and have the skills to aggregate, interpret, and present the resulting data (National Research Council, 2006, p.77; NSTA, 2007).

Honors and Advanced Level Course Note: Advanced courses require a greater demand on students through increased academic rigor.  Academic rigor is obtained through the application, analysis, evaluation, and creation of complex ideas that are often abstract and multi-faceted.  Students are challenged to think and collaborate critically on the content they are learning. Honors level rigor will be achieved by increasing text complexity through text selection, focus on high-level qualitative measures, and complexity of task. Instruction will be structured to give students a deeper understanding of conceptual themes and organization within and across disciplines. Academic rigor is more than simply assigning to students a greater quantity of work.

Special Notes:

Instructional Practices
Teaching from a range of complex text is optimized when teachers in all subject areas implement the following strategies on a routine basis:

  1. Ensuring wide reading from complex text that varies in length.
  2. Making close reading and rereading of texts central to lessons.
  3. Emphasizing text-specific complex questions, and cognitively complex tasks, reinforce focus on the text and cultivate independence.
  4. Emphasizing students supporting answers based upon evidence from the text.
  5. Providing extensive research and writing opportunities (claims and evidence).

Science and Engineering Practices (NRC Framework for K-12 Science Education, 2010)

  • Asking questions (for science) and defining problems (for engineering).
  • Developing and using models.
  • Planning and carrying out investigations.
  • Analyzing and interpreting data.
  • Using mathematics, information and computer technology, and computational thinking.
  • Constructing explanations (for science) and designing solutions (for engineering).
  • Engaging in argument from evidence.
  • Obtaining, evaluating, and communicating information.

Literacy Standards in Science
Secondary science courses include reading standards for literacy in science and technical subjects 6-12 and writing standards for literacy in history/social studies, science, and technical subjects 6-12.

You may also download the complete course including all required standards and notes sections using the export function located at the top of this page.

English Language Development ELD Standards
Teachers are required to provide listening, speaking, reading and writing instruction that allows English language learners (ELL) to communicate information, ideas and concepts for academic success in the content area of Science. For the given level of English language proficiency and with visual, graphic, or interactive support, students will interact with grade level words, expressions, sentences and discourse to process or produce language necessary for academic success The ELD standard should specify a relevant content area concept or topic of study chosen by curriculum developers and teachers which maximizes an ELL's need for communication and social skills.

Lesson Plans

The Surprising World of Complex Systems:

This lesson introduces students to complex systems and to basic concepts from the field of system dynamics that lie at the heart of systems thinking. These concepts include stocks and flows, feedback loops, unintended consequences, and the basic principle that the behavior of complex systems can best be understood by looking at the system as a whole, and specifically by analyzing the system’s underlying structure. The lesson introduces these topics through an immersion in (and a role-play simulation of) the dynamics of urban recycling systems, many of which have been thrown into crisis in the past two years. Through this current-affairs example of complex systems in crisis, we identify some key structural features that help to explain how these systems behave over time. We also discover how well-intentioned action can cause negative unintended consequences when we try to intervene in a complex system without understanding how it operates.

Type: Lesson Plan

Elasticity: Studying How Solids Change Shape and Size:

This lesson's primary focus is to introduce high school students to the concept of Elasticity, which is one of the fundamental concepts in the understanding of the physics of deformation in solids. The main learning objectives are: (1) To understand the essential concept of Elasticity and be able to distinguish simple solids objects based on degree and extent of their elastic properties; (2) To appreciate the utility of the elastic force vs. deformation curve through experiments; (3) To be aware of potential sources of error present in such experiments and identify corrective measures; and (4) To appreciate the relevance of Elasticity in practical applications.

Type: Lesson Plan

CO2: Find Out What It Means to You:

This BLOSSOMS lesson discusses Carbon Dioxide, and its impact on climate change. The main learning objective is for students to become more familiar with human production of Carbon Dioxide gas, as well as to gain an awareness of the potential for this gas to effect the temperature of Earth’s atmosphere. This lesson should take about an hour to complete. In order to complete the lesson, the teacher will need: printed copies of signs representing the different products and processes that take place in the carbon cycle (included), samples of matter that represent those products, handouts for the students to create a graphic of the carbon cycle (included) and graph paper or graphing software for students to create graphs. In the breaks of this BLOSSOMS lesson, students will be creating models of the carbon cycle as well as observing experiments and analyzing data from them. It is hoped that this lesson will familiarize students with ways in which carbon moves through our environment and provide them with some personal connection to the impact that an increased concentration of CO2 can have on air temperature. The goal is to spark their interest and hopefully to encourage them to ask and investigate more questions about the climate.

Understanding molecular polarity by changing the electron-negativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity. See how it works for real molecules in 3D.

Some learning goals:
•predict bond polarity using electron-negativity values
•indicate polarity with a polar arrow or partial charges
•rank bonds in order of polarity
•predict molecular polarity using bond polarity and molecular shape

Norn Genetics:

This is a simplified, interactive demonstration of genetic principles. Using a fictional species named the Norn, students can predict the outcome of genetic crosses (mono and di-hybrid, sex-linked, and multiple-allele). This could be used to strengthen the students understanding of genetics, practice Punnet squares, or practice calculation of genotypic/phenotypic ratios. However, it is unlikely to be useful as an independent assignment (if used as designed).

Type: Virtual Manipulative

Membrane Channel Simulations:

This interactive cell membrane simulation allows students to see how different types of channels allow particles to move through the membrane.

Sample learning goals:

  • Predict when particles will move through the membrane and when they will not.
  • Identify which particle type will diffuse depending on which type of channels are present.
  • Predict the rate of diffusion based on the number and type of channels present.
