Executive Summary
Science 10 develops students’ understanding of living and physical systems through chemistry, energy, genetics, and astronomy. Students investigate how atoms and energy are involved in chemical processes, how energy is conserved and transformed, how DNA contributes to biological diversity, and how evidence supports our understanding of the universe.
The course emphasizes scientific inquiry, evidence, experimentation, modelling, data analysis, and the ability to explain scientific ideas clearly.
Course Overview
Science 10 builds on the scientific knowledge and inquiry skills developed in earlier grades while preparing students for more specialized senior science courses.
Students study chemical reactions, energy transformations and nuclear science, genetics and biological diversity, and the formation of the universe. Throughout the course, these topics are connected by recurring ideas of systems, change, evidence, energy, and scientific explanation.
Students are expected not only to understand scientific concepts, but also to ask questions, conduct investigations, analyze evidence, evaluate methods and conclusions, and communicate what they have learned.
Teaching Approach
Science 10 should provide regular opportunities for students to investigate, model, observe, measure, analyze, and explain.
Laboratory activities and investigations are used where they meaningfully support the science. Students should become increasingly independent in selecting appropriate methods and equipment, collecting reliable qualitative and quantitative data, recognizing sources of error, and evaluating whether evidence supports a conclusion.
A useful recurring scientific process is:
Question → Predict → Investigate → Analyze → Explain → Evaluate
Safety, ethical considerations, environmental impacts, and First Peoples perspectives and knowledge should be incorporated where they are relevant to the scientific questions being studied.
Technology can support data collection, graphing, modelling, simulations, research, and communication, but students should understand the scientific reasoning behind the results.
Course Organization & Resources
At the beginning of the course, a detailed calendar is established to provide students with unit timelines, laboratory and assignment dates, assessment dates, and flexibility for schedule disruptions.
The main instructional sequence is:
Reactions → Energy → Genetics → Astronomy
The course website serves as the central location for lessons, assignments, laboratory activities, handouts, review materials, and assessment information.
Students should have regular access to appropriate laboratory equipment, safety equipment, scientific measuring tools, models, calculators, graphing tools, and digital simulations or data sets where useful.
What Students Learn
Reactions
This unit examines how atoms are rearranged during chemical reactions and how mass and energy are involved in those changes.
Students learn to:
- represent and interpret chemical reactions;
- describe the rearrangement of atoms during chemical change;
- investigate acid-base chemistry;
- apply the law of conservation of mass;
- distinguish between energy-absorbing and energy-releasing processes;
- examine practical applications and implications of chemical processes.
Students should understand that chemical reactions involve rearrangements of matter accompanied by changes in energy.
Energy
This unit explores energy as a quantity that can be stored, transferred, and transformed while remaining conserved. Students examine mechanical energy alongside nuclear energy and radiation.
Students learn to:
- distinguish between potential and kinetic energy;
- apply the law of conservation of energy;
- identify and analyze energy transformations;
- describe nuclear energy and radiation;
- compare processes associated with nuclear energy;
- examine local and global impacts of energy technologies.
The emphasis is on understanding that energy is conserved even as it changes form, and that energy technologies can affect living things and the environment.
Genetics
This unit examines how DNA stores and transmits genetic information, how genetic variation arises, and how that variation contributes to the diversity and evolution of living things. Students also explore how genetic knowledge is applied through modern technologies and the questions those applications can raise.
Students learn to:
- describe the structure and function of DNA and its relationship to genes and chromosomes;
- recognize and represent patterns of genetic inheritance;
- explain how mutations create genetic variation;
- distinguish between natural and artificial selection;
- connect genetic variation and selection to biological diversity and evolutionary change;
- investigate applications of genetics and biotechnology;
- evaluate scientific, ethical, environmental, and societal considerations associated with genetic technologies.
The emphasis is on understanding how DNA, inheritance, variation, and selection contribute to biological diversity and how genetic knowledge can be applied in society.
Astronomy
This unit examines how scientific evidence is used to investigate the origin, structure, and development of the universe.
Students learn to:
- describe the Big Bang theory;
- examine evidence used to support scientific models of the universe;
- describe how components of the universe have changed over time;
- interpret astronomical observations and data;
- examine methods and technologies used to collect astronomical information;
- use models and evidence to communicate explanations about the universe.
Students should recognize that our understanding of the universe is built from observations, evidence, models, and continually improving technology.
Assessment
Assessment is designed to provide evidence of both scientific understanding and the ability to investigate, analyze, and communicate scientifically.
Students are assessed through a combination of:
- assignments and structured practice;
- laboratory activities and investigations;
- data analysis and scientific problem solving;
- models, research, and applied science tasks;
- scientific communication and reflection;
- a final project exploring the life and contributions of a scientist.
Assessment should provide opportunities for students to ask questions, make predictions, select appropriate methods, collect and analyze evidence, apply scientific concepts, evaluate conclusions, and communicate their reasoning.
A successful scientific investigation is not defined only by obtaining an expected result. Students should also be able to interpret their evidence, recognize limitations, and explain what their results support.
Final Note
Science 10 is most effective when students see science as a way of understanding and investigating the world rather than simply a collection of facts to remember.
By the end of the course, students should be more confident asking scientific questions, conducting investigations, working with evidence and data, using models, evaluating scientific information, and communicating explanations.
Above all, students should leave Science 10 understanding that scientific knowledge develops through observation, evidence, testing, evaluation, and the willingness to revise explanations as new information becomes available.
