Ontario Curriculum | Adopted: 2008
A: Scientific Investigation Skills and Career Exploration
A1: demonstrate scientific investigation skills (related to both inquiry and research) in the four areas of skills (initiating and planning, performing and recording, analysing and interpreting, and communicating);
A1.6: Students will: compile accurate data from laboratory and other sources, and organize and record the data, using appropriate formats, including tables, flow charts, graphs, and/or diagrams
Identifying Nutrients
Use a variety of real-world lab tests to analyze common food samples in order to determine if the food is a carbohydrate, a protein, or a lipid. Tests that can be performed include: Benedict, Lugol, Biuret, and Sudan Red. 5 Minute Preview
A1.10: Students will: draw conclusions based on inquiry results and research findings, and justify their conclusions with reference to scientific knowledge
Digestive System
Digestion is a complex process, involving a wide variety of organs and chemicals that work together to break down food, absorb nutrients, and eliminate wastes. But have you ever wondered what would happen if some of those organs were eliminated, or if the sequence was changed? Can the digestive system be improved? Find out by designing your own digestive system with the Digestive System Gizmo. 5 Minute Preview
A1.11: Students will: communicate ideas, plans, procedures, results, and conclusions orally, in writing, and/or in electronic presentations, using appropriate language and a variety of formats (e.g., data tables, laboratory reports, presentations, debates, simulations, models)

C: Pathogens and Disease
C2: investigate the nature and growth of pathogens and the effectiveness of measures intended to prevent their spread;
C2.1: Students will: use appropriate terminology related to pathogens and diseases, including, but not limited to: parasite, epidemiology, pathogenesis, and vector
Virus Lytic Cycle
Release a lytic virus in a group of cells and observe how cells are infected over time and eventually destroyed. Data related to the number of healthy cells, infected cells, and viruses can be recorded over time to determine the time required for the virus to mature within a cell. 5 Minute Preview
C3: demonstrate an understanding of pathogens, the diseases they cause, and ways of controlling their spread.
C3.1: Students will: describe the characteristics and life cycles, including reproductive cycles, of representative pathogens (e.g., lysogenic cycle; lytic cycle; infectious cycle of malaria)

D: Nutritional Science
D2: investigate chemical components of and energy in food, and the processes by which food is digested;
D2.1: Students will: use appropriate terminology related to nutritional science, including, but not limited to: macromolecules, protein, starch, vitamin, carbohydrate, fats, lipids, pepsin, and amylase
Identifying Nutrients
Use a variety of real-world lab tests to analyze common food samples in order to determine if the food is a carbohydrate, a protein, or a lipid. Tests that can be performed include: Benedict, Lugol, Biuret, and Sudan Red. 5 Minute Preview

F: Biotechnology
F2: investigate various techniques used in biotechnology and how they are applied in the food industry and the health and agricultural sectors;
F2.1: Students will: use appropriate terminology related to biotechnology, including, but not limited to: selective breeding, hybridization, replication, mutation, genomics, and gene therapy
Evolution: Natural and Artificial Selection
Observe evolution in a fictional population of bugs. Set the background to any color, and see natural selection taking place. Compare the processes of natural and artificial selection. Manipulate the mutation rate, and determine how mutation rate affects adaptation and evolution. 5 Minute Preview
F3: demonstrate an understanding of biological processes related to biotechnology and of applications of biotechnology in the health, agricultural, and environmental sectors.
F3.1: Students will: explain various methods used, over time, in the field of biotechnology (e.g., use of living organisms to make or modify products, selective breeding to create particular breeds of animals, manipulation of genes to develop organisms with particular traits)

About STEM Cases
Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.
Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap
STEM Cases take between 30-90 minutes for students to complete, depending on the case.
Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.
Multiple grade-appropriate versions, or levels, exist for each STEM Case.
Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
