## General Course Information and Notes

### General Notes

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).

**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:

- Ensuring wide reading from complex text that varies in length.
- Making close reading and rereading of texts central to lessons.
- Emphasizing text-specific complex questions, and cognitively complex tasks, reinforce focus on the text and cultivate independence.
- Emphasizing students supporting answers based upon evidence from the text.
- 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. The courses also include speaking and listening standards. For a complete list of standards required for this course click on the blue tile labeled course standards. 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 Special Notes Section:**

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.

## Educational Game

Students attempt to save towns from damage prior to the arrival of several different natural disasters. Students will learn the importance of early prevention and actions to protect others, themselves and their property when faced with a natural disaster. Certain disasters are more appropriate for particular grade levels. Each scenario takes between 20 and 45 minutes to play, depending on the disaster for which your students are trying to prepare. There are five scenarios available, hurricane, tsunami, flood, earthquake, and wildfire. Each scenario can be played on easy, medium or hard difficulty levels. As with life, there are no "perfect solutions" to each scenario and no "perfect score", so students can play multiple times and the scenarios will still be slightly different.These simulation are part of a larger website that provides multiple links for natural disasters.

## Lesson Plans

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

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 CO_{2} 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.

The task could also be used to generate a group discussion on interpreting functions given by graphs.

Type: Problem-Solving Task

The purpose of this task is to illustrate through an absurd example the fact that in real life quantities are reported to a certain level of accuracy, and it does not make sense to treat them as having greater accuracy.

Type: Problem-Solving Task

This task operates at two levels. In part it is a simple exploration of the relationship between speed, distance, and time. Part (c) requires understanding of the idea of average speed, and gives an opportunity to address the common confusion between average speed and the average of the speeds for the two segments of the trip.

At a higher level, the task addresses MAFS.912.N-Q.1.3, since realistically neither the car nor the bus is going to travel at exactly the same speed from beginning to end of each segment; there is time traveling through traffic in cities, and even on the autobahn the speed is not constant. Thus students must make judgments about the level of accuracy with which to report the result.

Type: Problem-Solving Task

This is a challenging task, suitable for extended work, and reaching into a deep understanding of units. Students are given a scenario and asked to determine the number of people required to complete the amount of work in the time described. The task requires students to exhibit MAFS.K12.MP.1.1, Make sense of problems and persevere in solving them. An algebraic solution is possible but complicated; a numerical solution is both simpler and more sophisticated, requiring skilled use of units and quantitative reasoning. Thus the task aligns with either MAFS.912.A-CED.1.1 or MAFS.912.N-Q.1.1, depending on the approach.

Type: Problem-Solving Task

Students explore and manipulate expressions based on the following statement:

A function f defined for -a < x < a is even if f(-x)=f(x) and is odd if f(-x)=-f(x) when -a < x < a. In this task we assume f is defined on such an interval, which might be the full real line (i.e., a=8).

Type: Problem-Solving Task

Students compare graphs of different quadratic functions, then produce equations of their own to satisfy given conditions.

This exploration can be done in class near the beginning of a unit on graphing parabolas. Students need to be familiar with intercepts, and need to know what the vertex is. It is effective after students have graphed parabolas in vertex form (y=a(x–h)^{2}+k), but have not yet explored graphing other forms.

Type: Problem-Solving Task

This resource poses the question, "how many vehicles might be involved in a traffic jam 12 miles long?"

This task, while involving relatively simple arithmetic, promps students to practice modeling (MP4), work with units and conversion (N-Q.1), and develop a new unit (N-Q.2). Students will also consider the appropriate level of accuracy to use in their conclusions (N-Q.3).

Type: Problem-Solving Task

The task is a modeling problem which ties in to financial decisions faced routinely by businesses, namely the balance between maintaining inventory and raising short-term capital for investment or re-investment in developing the business.

Type: Problem-Solving Task

This task provides students the opportunity to make use of units to find the gas needed (MAFS.912.N-Q.1.1). It also requires them to make some sensible approximations (e.g., 2.92 gallons is not a good answer to part (a)) and to recognize that Felicia's situation requires her to round up. Various answers to (a) are possible, depending on how much students think is a safe amount for Felicia to have left in the tank when she arrives at the gas station. The key point is for them to explain their choices. This task provides an opportunity for students to practice MAFS.K12.MP.2.1: Reason abstractly and quantitatively, and MAFS.K12.MP.3.1: Construct viable arguments and critique the reasoning of others.

Type: Problem-Solving Task

This task requires students to recognize the graphs of different (positive) powers of x.

Type: Problem-Solving Task

The primary purpose of this task is to lead students to a numerical and graphical understanding of the behavior of a rational function near a vertical asymptote, in terms of the expression defining the function.

Type: Problem-Solving Task

The purpose of this task is to give students practice constructing functions that represent a quantity of interest in a context, and then interpreting features of the function in the light of the context. It can be used as either an assessment or a teaching task.

Type: Problem-Solving Task

This problem involves the meaning of numbers found on labels. When the level of accuracy is not given we need to make assumptions based on how the information is reported. An unexpected surprise awaits in this case, however, as no reasonable interpretation of the level of accuracy makes sense of the information reported on the bottles in parts (b) and (c). Either a miscalculation has been made or the numbers have been rounded in a very odd way.

This lesson introduces students to Green Chemistry, the design of chemical products and processes that reduce or eliminate the use and/or the generation of hazardous substances. Green chemistry is a proactive approach to pollution prevention that teaches chemists how to develop products and materials in a manner that does not use hazardous substances, thus avoiding much waste, hazards and associated costs. The goal of this lesson is to introduce students to the 12 Principles of Green Chemistry and how they relate to a chemical process. These principles provide a framework for scientists, engineers and chemistry students to use when designing new materials, products, processes, and systems. The Principles focus on sustainable design criteria and have proven to be the source of innovative solutions to a wide range of problems. Through this lesson, students will also use weight and measurement to understand the concept of a recipe as it is applied to a chemical process and think critically about that process and how it might be improved. Students will be asked to use a wasteful, inefficient procedure to make glue and be challenged to improve the procedure-during which they will unknowingly use the 12 Principles. Before starting this lesson, students should have been introduced to the periodic table and properties of matter. The estimated time for this lesson is 50-60 minutes.
