Line Graphs
Students draw line graphs. Line graphs show continuous change.
Bar Graphs
Students draw bar graphs. Bar graphs compare categories.
Scatter Plots
Students draw scatter plots. Scatter plots relate two variables.
Histograms
Students draw histograms. Histograms show distribution.
Scientific Models & Systems
Scientific Models
Students use scientific models. Models represent what cannot be seen directly.
Physical Models
Students build physical models. Physical models are tangible representations.
Conceptual Models
Students use conceptual models. Conceptual models express relationships in ideas.
Mathematical Models
Students use mathematical models. Mathematical models allow prediction.
Systems
Students analyse systems. A system has boundaries and parts.
Matter & Its Properties
Matter
Students study matter. Matter has mass and occupies space.
Physical Properties
Students identify physical properties. Physical properties do not change identity.
Chemical Properties
Students identify chemical properties. Chemical properties describe reactivity.
States of Matter
Students study states of matter. State depends on particle arrangement.
Solids
Students study solids. Solids have fixed shape and volume.
Atomic Structure
Atoms
Students study atoms. Atoms are the building blocks of matter.
Protons
Students study protons. Protons carry positive charge.
Neutrons
Students study neutrons. Neutrons are electrically neutral.
Electrons
Students study electrons. Electrons carry negative charge.
Atomic Number
Students use atomic number. Atomic number identifies the element.
Periodic Table & Elements
Periodic Table
Students use the periodic table. The table organises all elements.
Groups
Students study groups. Groups are vertical columns with shared properties.
Periods
Students study periods. Periods are horizontal rows.
Metals
Students study metals. Metals conduct and are malleable.
Nonmetals
Students study nonmetals. Nonmetals are poor conductors.
Chemical Bonding
Chemical Bonds
Students study chemical bonds. Bonds hold atoms together.
Ionic Bonds
Students study ionic bonds. Ionic bonds transfer electrons.
Covalent Bonds
Students study covalent bonds. Covalent bonds share electrons.
Metallic Bonds
Students study metallic bonds. Metallic bonds share a sea of electrons.
Valence Electrons
Students count valence electrons. Valence electrons form bonds.
Chemical Reactions
Chemical Reactions
Students study chemical reactions. Reactions rearrange atoms.
Reactants
Students identify reactants. Reactants are the starting substances.
Products
Students identify products. Products are what is formed.
Evidence of Chemical Change
Students identify evidence of chemical change. Colour, gas, and heat signal reaction.
Chemical Equations
Students write chemical equations. Equations represent reactions symbolically.
Chemical Reactions & Energy
Exothermic Reactions
Students study exothermic reactions. Exothermic reactions release energy.
Endothermic Reactions
Students study endothermic reactions. Endothermic reactions absorb energy.
Activation Energy
Students study activation energy. Activation energy is the barrier to reaction.
Chemical Energy
Students study chemical energy. Chemical energy is stored in bonds.
Energy Transfer
Students trace energy transfer. Energy moves during reaction.
Solutions, Acids & Bases
Solutions
Students study solutions. A solution is a uniform mixture.
Solutes
Students identify solutes. The solute dissolves.
Solvents
Students identify solvents. The solvent does the dissolving.
Concentration
Students measure concentration. Concentration is solute per volume.
Solubility
Students study solubility. Solubility depends on temperature.

Standards Note
Grade 10 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 science very differently. Some follow Biology in Grade 9 and Chemistry or Physics in Grade 10; others use Physical Science first; others teach an integrated sequence. 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 course requirements directly.
Illinois requires at least two years of science for high school graduation, and many districts require more or specify particular courses. 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 scientific evidence supports and what the Illinois science standards require. Students examine fossil, anatomical, and molecular evidence and reason from it themselves rather than being asked to accept conclusions on authority.
Climate change is taught as established science. Students work with temperature records, greenhouse gas measurements, and climate model output, and learn how scientists reach conclusions from converging independent data sets. Adaptation and mitigation are presented as responses being pursued, not as advocacy for any particular policy.
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 high voltages. Adult supervision is expected for practical work, and students are never asked to perform anything unsafe.
Content on cells, genetics, DNA, and biotechnology is academic biology and is not medical or genetic advice. Questions about individual or family health should be directed to a qualified medical professional.
Illinois schools and districts may use different textbooks, laboratory equipment, materials, pacing guides, and assessments. This is not the only Grade 10 Science syllabus available, and no specific textbook, kit, software, or assessment is required statewide.
This course develops the scientific understanding and reasoning that statewide assessments draw on, but it is not official test preparation and is not affiliated with any assessment programme.
It is important to distinguish between the Illinois science learning standards and the course structure created for this educational programme, which organises Grade 10 science into a month-by-month teaching sequence.
