Biology 30
Dive deeper into the complexity of living systems through homeostasis, reproduction, genetics, molecular biology, and population dynamics. Biology 30 builds on Biology 20 and prepares students to think critically about the human body, heredity, biotechnology, and ecological change.
Course Units
Nervous and Endocrine Systems
Study how the nervous and endocrine systems coordinate communication, maintain homeostasis, and help the body respond to internal and external stimuli.
Reproduction and Development
Examine human reproductive systems, hormonal regulation, embryonic and fetal development, and the societal impact of reproductive technologies.
Cell Division, Genetics and Molecular Biology
Explore mitosis, meiosis, inheritance patterns, DNA structure, protein synthesis, mutations, and the foundations of biotechnology.
Population and Community Dynamics
Analyze how populations change over time, how species interact within communities, and how ecological models help us understand environmental change.
Alberta Curriculum Outcomes
What You Will Learn
Key understandings and skills drawn from the Alberta Biology 30 program of studies.
Explain how neurons generate and transmit impulses, how synapses communicate signals, and how the nervous system coordinates physiological responses.
Describe the roles of the central and peripheral nervous systems, sensory receptors, reflex arcs, and major structures of the eye and ear.
Explain how endocrine glands and hormones such as insulin, glucagon, thyroxine, ADH, and cortisol help maintain homeostasis through feedback systems.
Describe the structures and functions of the male and female reproductive systems and explain how reproduction supports survival of the species.
Analyze hormonal regulation of the menstrual cycle, pregnancy, parturition, and lactation, and evaluate reproductive technologies from multiple perspectives.
Describe fertilization, implantation, embryonic and fetal development, and the influence of environmental factors and teratogens on development.
Compare mitosis and meiosis, explain chromosome behaviour, and analyze the significance of crossing over, nondisjunction, and chromosome number.
Solve genetics problems involving monohybrid, dihybrid, sex-linked, incomplete dominance, codominance, multiple alleles, and polygenic inheritance.
Explain DNA replication, transcription, and translation, and connect mutations to protein synthesis, inheritance, and genetic disorders.
Analyze population growth models, limiting factors, species interactions, and community change to explain ecological dynamics over time.
Interpret biological data, graphs, simulations, and published evidence to support conclusions and evaluate the reliability of sources and methods.
Assess how science, technology, and society intersect in areas such as hormone therapy, reproduction, biotechnology, genetics, and environmental stewardship.
Attitude Outcomes
Interest in Science
Build curiosity about biological systems, pursue meaningful questions, and explore future pathways in science, health, research, and biotechnology.
Mutual Respect
Recognize that scientific understanding grows through collaboration, multiple perspectives, and thoughtful discussion of ethical and social issues.
Scientific Inquiry
Seek evidence, test ideas carefully, question assumptions, and use biological reasoning when interpreting data, models, and scientific claims.
Collaboration
Work effectively with others during labs, discussions, investigations, and presentations while valuing shared responsibility and communication.
Stewardship
Consider the environmental and long-term consequences of scientific and technological decisions, especially in genetics, reproduction, and ecology.
Safety
Demonstrate safe and responsible behaviour in laboratory work, simulations, dissections, and all science learning environments.
Student Resources
How to Succeed in Biology 30
Learn processes in sequence. For many topics, the order matters: nerve transmission, hormone feedback loops, embryonic development, meiosis, and protein synthesis.
Connect structure to function. When you study a gland, organ, chromosome, or molecule, always ask what its shape or location helps it do.
Practise graphs and data. Biology 30 often includes hormone graphs, inheritance ratios, and ecology data. Do not only memorize notes.
Use diagrams actively. Redraw the neuron, menstrual cycle, stages of meiosis, and DNA to strengthen memory and improve explanation skills.
Say it out loud. Explain concepts verbally as if you are teaching someone else. If you cannot explain it clearly, review it again.
Separate the similar processes. Students often mix up mitosis vs. meiosis, DNA replication vs. transcription, and endocrine vs. nervous control. Compare them directly.
Memorize key vocabulary precisely. Terms like homeostasis, implantation, codominance, transcription, and carrying capacity need exact meaning.
Review a little every week. Biology 30 is dense. Frequent short review sessions work much better than one long cram session before a test.
