Why new Science Standards? Reduction of the United States’ competitive economic edge: Shrinking share of patents: Foreign competitors filed over half of U.S. Technology patent applications in 2010 Diminishing share of high-tech exports: U.S. share of high-tech exports is on the decline, while European’s has held steady and China’s has surpassed us.
Why new Science Standards? Lagging Achievement of U.S. Students: • U.S. ranked 14th in reading, 17th in science and 25th in math on the 2009 PISA. Less than 10% scored at the top on only 2 of the 6 performance levels. • U.S. is 12th in HS graduation rate among 36 OECD countries for which data is available. • Over 1/3 of 8th graders scored below basic on 2009 NAEP Science assessment • 78% of HS grads did not meet readiness benchmarks for one or more entry level college courses in MA, Sci, Reading and English
Why new Science Standards? Essential preparation for all careers in the modern workforce: • Many of the fastest growing occupations are those where science and math play a central role. • National Association of State Directors of Career Technical Education Consortium: • 14 of 16 career clusters call for 4 years of science, with remaining 2 calling for 3 years • All 16 call for 4 years of math Conclusion: To keep options open and maximize opportunities, All students should follow a rigorous program in both science and mathematics.
Why new Science Standards? Scientific and technological literacy for an educated society: • Beyond employability looms a larger question of what it take to thrive in today’s society. • Pandemics to energy shortages • Health care and retirement planning • 2003 National Assessment of Adult Literacy indicates that fewer than 1 in 3 college graduates can interpret data tables about blood pressure and physical activity
These facts tell us… • Classsroom experiences need to show the importance of Science in the real world • U.S. needs to employ more engineering in its science curriculum

The Overarching Goal of K-12 Science Education Frameworks… All students….. • Have some appreciationof the beauty and wonder of science. • Possess sufficient knowledge of science and engineering to engage in public discussions on related issues. • Are careful consumers of scientific and technological information related to their everyday lives. • Are able to continue to learn about science outside school. • Have the skills to enter careers of their choice, including careers in science, engineering, and technology.
Three Guiding Principles of the Science Frameworks Children are Born Investigators: • Research shows that children entering Kindergarten have surprisingly sophisticated ways of thinking about the world. • They learn from direct experiences with their environment, everyday activities, pursuing hobbies, watching television, playing with friends. • Research shows that the capacity of young children, from all backgrounds and all socioeconomic levels, to reason in sophisticated ways is much greater than has been long assumed. • Educators can build on what children already know and can do, whether it is a misconception or not. • Implications are for teachers to help students build progressively more sophisticated explanations of natural phenomena in grades K-5, rather than only focusing on factual information in these grades.
Three Guiding Principles of the Science Frameworks Focusing on Core Ideas and Practices: • Determine a limited set of core ideas to avoid coverage of multiple disconnected topics • Allow for deep exploration of important concepts • More Time for students to develop meaningful understanding • To actually practice science and engineering
Three Guiding Principles of the Science Frameworks Understanding Develops Over Time K-12 Learning Progressions: • Describes how students’ understanding matures over time and the instructional supports and experiences that are needed for this to happen. • Supports increasingly sophisticated learning • Each component idea in the frameworks has a set of grade band “endpoints” by the end of grades 2, 5, 8, and 12.
PS1.A: Structure and Properties of MatterHow do particles combine to form the variety of substances one observes? Grade Band Endpoints for PS1.A By the end of grade 2. Matter exists as different substances (e.g., wood, metal, water), and many of them can be either solid or liquid, depending on temperature.Substances can be described and classified by their observable properties (e.g., visual, aural, textural), by their uses, and by whether they occur naturally or are manufactured. Different properties are suited to different purposes. A great variety of objects can be built up from a small set of pieces. Objects or samples of a substance can be weighed and their size can be described and measured. (Boundary: volume is introduced only for liquid measure.)
Grade Band Endpoints for PS1.A By the end of grade 5. Matter of any type can be subdivided into particles that are too small to see, but even then the matter still exists and can be detected by other means (e.g., by weighing or by its effects on other objects). For example, a model showing that gases are made from matter particles that are too small to see and are moving freely around in space can explain many observations including: the impacts of gas particles on surfaces (e.g., of a balloon) and on larger particles or objects (e.g., wind, dust suspended in air), and the appearance of visible scale water droplets in condensation, fog, and, by extension, also in clouds or the contrails of a jet. The amount (weight) of matter is conserved when it changes form, even in transitions in which it seems to vanish (e.g., sugar in solution, evaporation in a closed container). Measurements of a variety of properties (e.g., hardness, reflectivity) can be used to identify particular substances. (Boundary: At this grade level, mass and weight are not distinguished, and no attempt is made to define the unseen particles or explain the atomic-scale mechanism of evaporation and condensation).
Grade Band Endpoints for PS1.A By the end of grade 8. All substances are made from some 100 different types of atoms, which combine with one another in various ways. Atoms form molecules that range in size from two to thousands of atoms. Pure substances are made from a single type of atom or molecule; each pure substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations.Solids may be formed from molecules, or they may be extended structures with repeating subunits (e.g., crystals). The changes of state that occur with variations in temperature or pressure can be described and predicted using these models of matter. (Boundary: Predictions here are qualitative, not quantitative.)
Grade Band Endpoints for PS1.A By the end of grade 12. Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states. The structure and interactions of matter at the bulk scale are determined by electrical forces within and between atoms.Stable forms of matter are those in which the electric and magnetic field energy is minimized. A stable molecule has less energy, by an amount known as the binding energy, than the same set of atoms separated; one must provide at least this energy in order to take the molecule apart.
Grade Band Endpoints for PS1.A You can see the learning progressions and how learning becomes more sophisticated from 2nd grade through 12th grade
8 Practices for K-12 ClassroomsWhat Students Should Be Able To Do! • Asking Questions (for science) and defining problems (for engineering) • Developing and Using Models • Planning and Conducting Investigations • Analyzing and Interpreting Data
8 Practices for K-12 Classrooms • Applying 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
Practice 1: Asking Questions and Defining Problems Questions are the engine that drive science and engineering. • Science asks • What exists and what happens? • Why does it happen? • How does one know? • Engineering asks: • What can be done to address a particular human need or want? • How can the need be better specified? • What tools and technologies are available, or could be developed, for addressing this need? • Both science and engineering ask: • How does one communicate phenomena, evidence, explanations, and design solutions?
Learning Progression for Asking Questions and Defining Problems Students at any grade level should be able to ask questions of each other about the texts they read, the features of the phenomena they observe, and conclusions they draw from their models or scientific investigations. For engineering, they should ask questions to define the problem to be solved and to elicit ideas that lead to the constraints and specifications for its solution. As they progress across the grades, their questions should become more relevant, focused, and sophisticated.
Learning Progression for Asking Questions and Defining Problems Facilitating such evolution will require a classroom culture: • that respects and values good questions • offers opportunities to refine questions and questioning strategies • incorporates the teaching of effective questioning strategies across all grade levels. As a result, students will become increasingly proficient…. • at posing questions that request relevant empirical evidence • at refining a model, an explanation or an engineering problem • at challenging the premise of an argument or the suitability of a design.
Goals for Asking Questions By grade 12 students should be able to: • Ask questions about the natural and human-built worlds—for example: Why are there seasons? What do bees do? Why did that structure collapse? How is electric power generated? • Distinguish a scientific question (e.g., Why do helium balloons rise?) from a nonscientific question (Which of these colored balloons is the prettiest?). • Formulate and refine questions that can be answered empirically in a science classroom and use them to design an inquiry or construct a pragmatic solution. • Ask probing questions that seek to identify the premises of an argument, request further elaboration, refine a research question or engineering problem, or challenge the interpretation of a data set—for example: How do you know? What evidence supports that argument? • Note features, patterns, or contradictions in observations and ask questions about them. • For engineering, ask questions about the need or desire to be met in order to define constraints and specifications for a solution.
The Three Dimensions of the Science Frameworks 1. Scientific and Engineering Practices • Asking questions (for science) and defining problems (for engineering) • Developing and using models • Planning and carrying out investigations • Analyzing and interpreting data • Using mathematics and computational thinking • Constructing explanations (for science) and designing solutions (for engineering) • Engaging in argument from evidence • Obtaining, evaluating, and communicating information
2. Crosscutting Concepts • Patterns • Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them. • Cause and effect: Mechanism and explanation • Investigating and explaining causal relationships; testing these relationships across given contexts and using the results to predict and explain events in new contexts. • Scale, proportion, and quantity • Changes in scale, proportion, or quantity affect a system’sstructure and performance
2.Crosscutting Concepts(continued) • Systems and system models • Defining the system under study and making a model of that system provides tools for understanding and testing ideas. • Energy and matter: Flows, cycles, and conservation • Tracking fluxes of energy and matter into, out of, and within systems helps one understand the systems’ possibilities and limitations. • Structure and function • How an object or living thing is shaped and its substructure determine many of its properties and functions. • Stability and change • Conditions of stability and determinants of rates of change or evolution or a system are critical elements of study.
3. Disciplinary Core Ideas Physical Sciences • PS 1: Matter and its interactions • PS 2: Motion and stability: Forces and interactions • PS 3: Energy • PS 4: Waves and their applications in technologies for information transfer Life Sciences • LS 1: From molecules to organisms: Structures and processes • LS 2: Ecosystems: Interactions, energy, and dynamics • LS 3: Heredity: Inheritance and variation of traits • LS 4: Biological evolution: Unity and diversity Earth and Space Sciences • ESS 1: Earth’s place in the universe • ESS 2: Earth’s systems • ESS 3: Earth and human activity Engineering, Technology, and the Applications of Science • ETS 1: Engineering design • ETS 2: Links among engineering, technology, science, and society
What does deep understanding look like instructionally? Instruction must go from just….. • Explaining concepts • Providing definitions and answers • Stating conclusions • Providing closure • Heavy reliance on Lecturing
