The planning and assessmentdocument is available both in print and on the ministry’s website, at http://www.edu.gov.on.ca.

The Place of Science in the Curriculum

During the twentieth century, science has come to play an increasingly important role in thelives of all Canadians. It underpins many of the technologies that we now take for granted,from life-saving pharmaceuticals to computers and other information technologies. There isevery reason to expect that science and its impact on our lives will continue to grow as weenter the twenty-first century. Consequently, scientific literacy for all has become the goal ofscience education throughout the world, and has been given expression in Canada in theCommon Framework of Science Learning Outcomes, K to 12: Pan-Canadian Protocol for Collaborationon School Curriculum (Council of Ministers of Education, Canada, 1997). Scientific literacy canbe defined as possession of the scientific knowledge, skills, and habits of mind required tothrive in the science-based world of the twenty-first century.

Achieving excellence in scientific literacy is not the same as becoming a science specialist.The notion of thriving in a science-based world applies as much to a small-business person, alawyer, an elementary school teacher, or an office worker as it does to a doctor, an engineer, ora research scientist. While the specific knowledge and skills required for each of these occupa-tions vary, the basic goal of thriving in a science-based world remains the same. Achievementof both excellence and equity underlies the goals of the new science program at the secondarylevel. Accordingly, science courses have been designed for a wide variety of students, takinginto account their interests and possible postsecondary destinations. Some courses have beendesigned to serve as preparation for specialist studies in science-related fields; others have been

3I N T R O D U C T I O N

designed for students intending to go on to postsecondary education but not to study science;yet others have been designed with the needs of the workplace in mind. The overall intentionis that all graduates of Ontario secondary schools will achieve excellence and a high degree ofscientific literacy while maintaining a sense of wonder about the world around them.Accordingly, the curriculum reflects new developments on the international science scene andis intended to position science education in Ontario at the forefront of science educationaround the world.

Science has significant, though varied, connections with many other disciplines. Science isrelated in many ways to the economies of all developed nations, including Canada, and plays amajor role in public and private decisions in many areas of society. It is critical, for example, todecisions and developments relating to sustainable development. Thus, science cannot betaught in isolation, but must be linked to other disciplines. Clearly, many topics studied inmathematics and technological education overlap with topics covered in science. Similar linksexist with geography and other areas of social studies. Communication is, of course, extremelyimportant in science, as it is in all disciplines – both in terms of reading and writing, and in theuse of information technology for collecting, organizing, and expressing information. Thenewer aspects of the science curriculum – especially those that focus on science, technology,society, and the environment (STSE) – call for students to deal with the impacts of science onsociety, and this requirement brings in issues that relate to human values. Science can thereforenot be viewed as merely a matter of “facts”; rather, it is a subject in which students learn toweigh the complex combinations of fact and value that developments in science and technol-ogy have given rise to in modern society.

Subject matter from any course in science can be combined with subject matter from one or more courses in other disciplines to create an interdisciplinary course. The policies and procedures regarding the development of interdisciplinary courses are outlined in the interdis-ciplinary studies curriculum policy document.

The secondary curriculum in science builds on three basic goals that run through every gradeand strand of the elementary curriculum and that reflect the essential triad of knowledge, skills,and the ability to relate science to technology, society, and the environment (STSE). In thesecondary program, these goals vary somewhat according to the type of course (academic orapplied), but they are always present in some form and serve to unify the program (see page 4).Science is approached in all courses not only as an intellectual pursuit but also as an activity-based enterprise operating within a social context.

The content of the secondary science program also builds on the five strands present in theelementary curriculum, although less emphasis is placed on technological education, which isa distinct discipline at the secondary level. In particular, the transition from Grade 8 to Grade9 is a smooth one because of the close alignment of both the elementary and the secondaryprogram with the pan-Canadian Common Framework of Science Learning Outcomes.

Overview

The overall aim of the secondary science program is to ensure scientific literacy for every secondary school graduate. This aim can be achieved by meeting three overall goals for everystudent. The secondary science program, from Grade 9 through Grade 12, is designed to pro-mote these goals:

– to understand the basic concepts of science;

– to develop the skills, strategies, and habits of mind required for scientific inquiry;

– to relate science to technology, society, and the environment.

Each of these three goals is defined more specifically within each of the courses that make upthe science program. There are always three goals (stated in each course description) and,within each strand, or unit of science content, always three overall expectations and three setsof specific expectations. The same three goals also provide the basis for assessment of studentachievement in science.

Two types of courses are offered in the Grade 9 and 10 science program: academic and applied.(SeeThe Ontario Curriculum, Grades 9 and 10: Program Planning and Assessment, 1999 for adescription of the different types of secondary school courses.) Courses offered in sciencemust be delivered as full courses, rather than as two half-credit courses.

Teaching Approaches

The expectations in science courses call for an active, experimental approach to learning, withall students participating regularly in laboratory activities. Laboratory activities can reinforce thelearning of scientific concepts and promote the development of the skills of scientific investiga-tion and communication. Where opportunity allows, students might be required, as part of theirlaboratory activities, to design and research a real scientific problem for which the results areunknown.

The goal of relating science to technology, society, and the environment (STSE) is an importantnew feature of this curriculum. In order to attain this goal, connections between science andtechnology and between science and the world beyond the school must be integrated into stu-dents’ learning of scientific concepts and skills. Where possible, concepts should be introducedin the context of real-world problems and issues.

Curriculum Expectations

The expectations identified for each course describe the knowledge and skills that studentsare expected to develop and demonstrate in their class work, on tests, and in various otheractivities on which their achievement is assessed and evaluated.

Two sets of expectations are listed for each strand, or broad curriculum area, of each course.The overall expectations describe in general terms the knowledge and skills that students areexpected to demonstrate by the end of each course. The specific expectations describe theexpected knowledge and skills in greater detail.

The specific expectations are organized under subheadings. This organization is not meant toimply that the expectations in any one group are achieved independently of the expectationsin the other groups. The subheadings are used merely to help teachers focus on particularaspects of knowledge and skills as they plan learning activities for their students.

Many of the expectations are accompanied by examples or sample problems, given in paren-theses. These examples and problems are meant to illustrate the kind of skill, the specific areaof learning, the depth of learning, and/or the level of complexity that the expectation entails.They are intended as a guide for teachers rather than as an exhaustive or mandatory list.

StrandsIn Grades 9 and 10, the following four subdisciplines of science are treated as strands withineach course:

– Biology

– Chemistry

– Earth and Space Science

– Physics

The topics treated within each strand in each of the courses in Grades 9 and 10 are outlined inthe following table. Environmental science is integrated into the curriculum expectations ofevery science course.

Some Considerations for Program Planning in Science

Teachers who are planning a program in science must take into account considerations in anumber of important areas. Essential information that pertains to all disciplines is provided inthe companion piece to this document, The Ontario Curriculum, Grades 9 and 10: ProgramPlanning and Assessment, 1999. The areas of concern to all teachers that are outlined thereinclude the following:

– types of secondary school courses

– education for exceptional students

– the role of technology in the curriculum

– English as a second language (ESL) and English literacy development (ELD)

– career education

– cooperative education and other workplace experiences

– health and safety

Considerations relating to the areas listed above that have particular relevance for programplanning in science are noted here.

Education for Exceptional Students. In planning programs in science, teachers should recog-nize that exceptional students may require focused and specialized directions, as well asadvance instruction and additional practice in the use of equipment. Issues relating to safety inthe laboratory and to students’ ability to read laboratory manuals and use laboratory equip-ment must be addressed before students can be expected to participate effectively. Changes toteaching materials may involve the use of large-print activity sheets, the highlighting of keypoints on print materials, and the use of alternative texts at a suitable reading level. Assessmentstrategies should allow students to demonstrate their understanding of scientific concepts in avariety of ways, such as by performing experiments, creating displays and models, and tape-recording observations. Computer programs may be used to provide opportunities for scien-tific practice and for recording results.

The Role of Technology in the Curriculum. In science, students gain “hands-on” experiencewith technology in the laboratory. Apparatus as diverse as digital balances and volumetricapparatus in chemistry, microscopes and Petri dishes in biology, and air tables and ammeters inphysics provide the kinesthetic learner with unique learning experiences. Computers can beused in science to support laboratory investigations; for example, electronic probes can be usedto monitor variables such as temperature, pH, and velocity. Computer programs can also beused to process class data and to simulate environmental or industrial scenarios, or animal dis-sections. Care must be taken, however, to ensure that computer-assisted laboratory programsare not used in situations where students’ own technical skills should be developed, such as inanalysing and graphing data.

The Internet is a particularly valuable source of scientific information that students should betaught to access. In addition, some programs enable students to conduct scientific investiga-tions and then use the tools of electronic communication to compare their results and analyseswith those of students in other parts of Canada and around the world.

43S O M E C O N S I D E R A T I O N S F O R P R O G R A M P L A N N I N G I N S C I E N C E

English As a Second Language and English Literacy Development (ESL/ELD). Science pre-sents particular linguistic challenges to all students because of its specialized terminology andlanguage structures. Science teachers who have ESL/ELD students in their classes shouldrespond to the special needs of these students, providing support with respect to their compre-hension and use of language in a scientific context.

Career Education. Ongoing scientific discoveries, coupled with rapidly evolving technologies,have resulted in an exciting environment in which creativity and innovation thrive, bringingabout new career opportunities. Today’s employers seek candidates with strong critical-think-ing and problem-solving skills and the ability to work cooperatively in a team environment –traits that are developed through participation in the science program. The program should bedesigned to give students an opportunity to explore science-related careers.

Cooperative Education and Other Workplace Experiences. Through participation in science-related learning activities in commercial, industrial, government, or academic laboratory settings, students can experience the application of knowledge and skills in specific areas ofscience in settings outside the school. These experiences give students the opportunity topractise and develop their own skills in problem solving, critical thinking, teamwork, and thesafe and accurate use of scientific procedures and tools. In addition, they provide students witha clearer sense of the nature of careers in science-related fields.

Health and Safety. Teachers are responsible for ensuring the safety of students during class-room activities and for teaching students to assume responsibility for their own and others’safety. They must model safe practices and communicate safety expectations to students inaccordance with school board and ministry policies.This concern for safety in science requiresthat students demonstrate:

– knowledge about the materials, tools, processes, and procedures used in science;

– skill in performing tasks in the laboratory;

– knowledge about health and safety concerns and about the care of living things (plants andanimals) that are brought into the classroom;

– concern for the health and safety of self and others.

Students demonstrate the knowledge, skills, and habits of mind required for safe involvementin science when they, for example:

– maintain a well-organized and uncluttered work space;

– carefully follow the instructions and example of the teacher;

– identify possible health and safety concerns;

– follow established safety procedures;

– suggest and implement appropriate safety procedures in new situations;

– comply with Workplace Hazardous Materials Information System (WHMIS) legislation.

The achievement chart that follows identifies four categories of knowledge and skills in science – Knowledge/Understanding, Inquiry, Communication, and Making Connections.These categories encompass all the curriculum expectations in courses in the discipline. Foreach of the category statements in the left-hand column, the levels of student achievement aredescribed. (Detailed information on the achievement levels and on assessment, evaluation, andreporting policy is provided in The Ontario Curriculum, Grades 9 and 10: Program Planning and Assessment, 1999.)

The achievement chart is meant to guide teachers in:– planning instruction and learning activities that will lead to the achievement of the curricu-

lum expectations in a course;– planning assessment strategies that will accurately assess students’ achievement of the cur-

riculum expectations;– selecting samples of student work that provide evidence of achievement at particular levels;– providing descriptive feedback to students on their current achievement and suggesting

strategies for improvement;– determining, towards the end of a course, the student’s most consistent level of achievement

of the curriculum expectations as reflected in his or her course work;– devising a method of final evaluation;– assigning a final grade.

The achievement chart can guide students in:– assessing their own learning;– planning strategies for improvement, with the help of their teachers.

The achievement chart provides a standard province-wide method for teachers to use inassessing and evaluating their students’ achievement. Teachers will be provided with materialsthat will assist them in improving their assessment methods and strategies and, hence, theirassessment of student achievement. These materials will contain samples of student work(exemplars) that illustrate achievement at each of the levels (represented by associated percent-age grade ranges). Until these materials are provided, teachers may continue to follow theircurrent assessment and evaluation practices.

To ensure consistency in assessment and reporting across the province, the ministry will pro-vide samples of student work that reflect achievement based on the provincial standard, andother resources based on the achievement charts. As these resources become available, teacherswill begin to use the achievement charts in their assessment and evaluation practices.

To support this process, the ministry will provide the following:– a standard provincial report card, with an accompanying guide– course profiles– exemplars– curriculum and assessment videos– training materials– an electronic curriculum planner

The Achievement Chart for Science

45T H E A C H I E V E M E N T C H A R T F O R S C I E N C E

When planning courses and assessment, teachers should review the required curriculumexpectations and link them to the categories to which they relate. They should ensure that allthe expectations are accounted for in instruction, and that achievement of expectations isassessed within the appropriate categories. The descriptions of the levels of achievement givenin the chart should be used to identify the level at which the student has achieved the expec-tations. Students should be given numerous and varied opportunities to demonstrate theirachievement of the expectations across the four categories. Teachers may find it useful to pro-vide students with examples of work at the different levels of achievement.

The descriptions of achievement at level 3 reflect the provincial standard for student achieve-ment. A complete picture of overall achievement at level 3 in a course in science can be constructed by reading from top to bottom in the column of the achievement chart headed“70–79% (Level 3)”.

Explanatory Notes

The following definitions are intended tohelp teachers and parents/guardians use thisdocument.

Acceleration.The rate of change of velocity.

Astronomical Unit.The average distanceof the Earth from the Sun.

Atomic structure. The configuration ofsubatomic particles within an atom (e.g., anatom of hydrogen has the structure of oneproton in its nucleus surrounded by oneelectron).

Bioaccumulation.The process by whichsubstances (poisons, chemicals, etc.) collect inanimal tissue in progressively higher concen-trations towards the top of the food chain.

Biosphere. The portion of the planet Earththat supports life, and the living organismswithin it.

Celestial object. A naturally occurringbody in the skies, such as a star, planet, orasteroid.

Cell. The smallest component of a livingsystem.

Chemical property. A characteristic of asubstance that describes its ability to enterinto a chemical reaction (e.g., an acid’scapacity to be neutralized by a base; the ten-dency of iron to rust).

Chemical reaction. A process in whichnew substances with new properties areformed (e.g., the burning of wood to formsmoke and ash, with heat given off).

Compound. A substance made up of twoor more elements (e.g., water is a compoundconsisting of two elements, hydrogen andoxygen).

Current electricity.The flow of electricityin a circuit through a conductor.

Displacement (in the context of physics).The shortest directed distance movedbetween two points or the distance movedin a given direction.

Ecology.The study of all the interactionsthat occur within the biosphere.

Ecosystem. A group of living organismsthat, along with their abiotic (i.e., non-living) environment, form a self-regulatingsystem through which energy and materialsare transferred.

Electrostatics.The study of electricity atrest. It is concerned with electrical chargesthat move very little.

Element. A type of substance that cannotbe broken down into simpler substances(e.g., iron, sulphur, oxygen).

Investigation. See scientific investigation.

IUPAC. International Union of Pure andApplied Chemistry. Scientists have organizedIUPAC as a governing body for scientificcommunication that specifies rules forchemical names and symbols.

Light year. The distance travelled by lightin one year.

Meteorology. The study of the atmosphereand weather systems.

Motion sensor. An ultrasonic device thatmeasures the distance between the deviceand the object being pointed at.

Operational definition. A way of definingphysical quantities which shows how theyare observed, described, and measured (e.g.,“Electric current is the rate of flow of chargepast a point and is determined by measuringthe charge that passes a point each second”).

Periodic table. A graphic arrangement ofelements into rows and columns, devised byMendeleev in the nineteenth century, basedon patterns of similar properties.

49E X P L A N A T O R Y N O T E S

Photo-gate. A timing device used inmotion experiments. The timing processbegins when the timed object intecepts thebeam of the photo-gate and ends when thebeam is restored.

Physical property. A characteristic of asubstance that does not involve its changinginto another substance (e.g., density, hard-ness, smell).

Robotics.The use of machines (nowadays,usually electronically controlled) to replacehuman actions.

Scientific investigation. An investigationthat involves the systematic application ofconcepts and procedures (e.g., experimenta-tion and research, observation and measure-ment, analysis and dissemination of data) thatrequire skill and habits of mind which arefundamental to the development of scientificknowledge and that have proven over timeto be useful in advancing scientific knowledge.

SI.The international system of measurementunits, including such terms as kilogram percubic metre and metre per second (from theFrench Système international d’unités).

Solar system.The system of planets andother celestial bodies governed by the Sun.
