Scientific Modeling & Systems Thinking
Scientific Models
Students use scientific models. Models represent what cannot be seen.
Conceptual Models
Students use conceptual models. Conceptual models express relationships.
Mathematical Models
Students use mathematical models. Mathematical models enable prediction.
System Components
Students identify system components. Components are the system’s parts.
Inputs
Students identify inputs. Inputs enter the system.
Cell Structure & Function
Cell Theory
Students study cell theory. All living things are made of cells.
Prokaryotic Cells
Students study prokaryotes. Prokaryotes lack a nucleus.
Eukaryotic Cells
Students study eukaryotes. Eukaryotes have membrane-bound organelles.
Cell Membrane
Students study the cell membrane. The membrane controls what enters.
Nucleus
Students study the nucleus. The nucleus holds genetic material.
Cellular Transport & Homeostasis
Diffusion
Students study diffusion. Diffusion moves particles down a gradient.
Osmosis
Students study osmosis. Osmosis is water movement across a membrane.
Active Transport
Students study active transport. Active transport requires energy.
Passive Transport
Students study passive transport. Passive transport needs no energy.
Concentration Gradients
Students study concentration gradients. Gradients drive passive movement.
Cellular Energy & Metabolism
ATP
Students study ATP. ATP is the cell’s energy currency.
Cellular Respiration
Students study cellular respiration. Respiration releases stored energy.
Glycolysis
Students study glycolysis. Glycolysis splits glucose in the cytoplasm.
Krebs Cycle Introduction
Students meet the Krebs cycle. The cycle occurs in the mitochondria.
Electron Transport
Students study electron transport. Electron transport produces most ATP.
DNA, Genes & Chromosomes
DNA Structure
Students study DNA structure. DNA is a double helix.
Nucleotides
Students study nucleotides. Nucleotides are DNA’s building blocks.
Genes
Students study genes. Genes code for proteins.
Chromosomes
Students study chromosomes. Chromosomes package DNA.
Genetic Information
Students study genetic information. DNA stores the instructions.
Protein Synthesis & Gene Expression
RNA
Students study RNA. RNA carries and interprets genetic messages.
Transcription
Students study transcription. Transcription copies DNA into RNA.
Translation
Students study translation. Translation builds proteins from RNA.
Messenger RNA
Students study messenger RNA. mRNA carries the code to the ribosome.
Ribosomes
Students study ribosomes. Ribosomes are the assembly sites.
Genetics & Heredity
Alleles
Students study alleles. Alleles are gene variants.
Genotype
Students study genotype. Genotype is the allele combination.
Phenotype
Students study phenotype. Phenotype is what is observed.
Dominant Traits
Students study dominant traits. Dominant alleles mask recessive ones.
Recessive Traits
Students study recessive traits. Recessive traits need two copies.
Genetic Variation & Biotechnology
Mutations
Students study mutations. Mutations can be harmful, neutral, or beneficial.
Genetic Variation
Students study genetic variation. Variation exists in every population.
Natural Variation
Students study natural variation. Natural variation arises without intervention.

Standards Note
Grade 11 Science in Illinois is guided by the Illinois Learning Standards for Science, which are the Next Generation Science Standards. At high school these are organised into Physical Science, Life Science, Earth and Space Science, and Engineering, Technology and Applications of Science, with performance expectations spanning grades 9–12 rather than assigned to a single grade.
Illinois high schools organise Grade 11 science very differently. Some students take Chemistry, some Physics, some Environmental Science, some an Advanced Placement course, and some an integrated third-year course. This syllabus is deliberately integrated across all four domains so it supports students on any of these pathways. Families should confirm their own school’s sequence and requirements directly.
Illinois requires at least two years of science for high school graduation, and many districts require three. Families should confirm graduation and credit requirements with their own school or district.
Evolution by natural selection is taught as established science, because that is what the evidence supports and what the Illinois science standards require. Students examine fossil, anatomical, molecular, and phylogenetic evidence and reason from it themselves.
Climate change is taught as established science. Students work directly with temperature records, greenhouse gas measurements, ocean and atmospheric circulation, and climate model output, and learn how scientists reach conclusions from converging independent data sets. The course does not advocate for any specific policy response.
Laboratory safety is taught before any practical work. All activities in this course are designed to be safe in a home setting, use readily available household materials, and involve no hazardous chemicals, open flames, or mains electricity. Adult supervision is expected, and students are never asked to perform anything unsafe. Electrical work uses low-voltage batteries only.
The Genetic Variation and Biotechnology module covers genetic engineering, gene editing, genetically modified organisms, and genetic testing. These raise genuine ethical, legal, and social questions on which reasonable people disagree. The course presents the science accurately and the debates fairly, and does not tell students what to conclude.
Content on cells, genetics, genetic disorders, and health is academic biology and is not medical or genetic advice. Questions about individual or family health, or about genetic testing decisions, should be directed to a qualified medical professional or genetic counsellor.
Illinois schools and districts may use different textbooks, laboratory equipment, materials, pacing guides, and assessments. This is not the only Grade 11 Science syllabus available, and no specific resource is required statewide.
This course develops the scientific understanding that statewide and college entrance assessments draw on, but it is not official test preparation and is not affiliated with any assessment or examination programme.
It is important to distinguish between the Illinois science learning standards and the course structure created for this educational programme, which organises Grade 11 science into a month-by-month teaching sequence.
