Illinois Science — Grade 4
Comprehensive Course Syllabus
Course Overview
Our Illinois Grade 4 Science course is built around energy, waves, structure and function, and Earth processes — the four big ideas of the Grade 4 standards. It opens with inquiry, investigation skills, measurement, data representation, and scientific models.
The physical science strand covers energy in five forms and how it transfers, motion and forces including friction and gravity, patterns of motion, waves, sound, and light, followed by matter, changes in matter, and the properties of materials including conductivity.
The life science strand focuses on structure and function: plant structures, animal structures from skeletons to sensory organs, plant and animal life cycles including metamorphosis, and adaptations.
The ecology strand covers ecosystems, food chains and food webs with producers, consumers, and decomposers, and ecosystem interactions including competition, predation, and human effects.
The earth science strand covers Earth materials, rocks and minerals with property testing, weathering and erosion, landforms, weather, climate, and the water cycle, followed by natural resources and environmental science.
The course closes with engineering design with criteria and constraints, STEM challenges, and science, technology and society, before a full year-end review.
Introduction to Scientific Inquiry
What Is Science?
Students learn what science is. Science explains the world using evidence.
Scientific Questions
Students ask scientific questions. Testable questions can be investigated.
Observation
Students observe carefully. Observation is where science starts.
Curiosity
Students build curiosity. Curiosity drives every investigation.
Evidence
Students gather evidence. Evidence decides whether an idea holds.
Scientific Investigation Skills
Planning Investigations
Students plan investigations. A plan makes fair testing possible.
Variables Introduction
Students meet variables. Variables are the things that can change.
Fair Tests
Students design fair tests. A fair test changes only one variable.
Measurement
Students measure accurately. Measurement makes data comparable.
Tools
Students use scientific tools. The right tool gives the right answer.
Scientific Measurement
Length
Students measure length. Rulers give exact lengths.
Mass
Students measure mass. Scales give an exact reading.
Volume
Students measure volume. Marked containers give exact volumes.
Temperature
Students measure temperature. Thermometers give numerical readings.
Time
Students measure time. Timing matters in many experiments.
Data Collection & Representation
Data Tables
Students make data tables. Tables organise raw results.
Tally Charts
Students use tally charts. Tallies count quickly in fives.
Bar Graphs
Students make bar graphs. Bar height shows the amount.
Line Plots
Students make line plots. Line plots show the distribution.
Picture Graphs
Students make picture graphs. Each picture stands for a number.
Scientific Models
What Is a Model?
Students learn what a model is. A model represents something real.
Physical Models
Students build physical models. Physical models can be handled.
Diagram Models
Students draw diagram models. Diagrams show structure clearly.
Earth Models
Students use Earth models. Globes model the whole planet.
System Models
Students model systems. Systems have parts that interact.
Energy Around Us
What Is Energy?
Students learn what energy is. Energy makes things happen.
Forms of Energy
Students identify forms of energy. Energy takes several distinct forms.
Light Energy
Students study light energy. Light energy travels from a source.
Sound Energy
Students study sound energy. Sound energy travels through matter.
Heat Energy
Students study heat energy. Heat moves from hot to cold.
Energy Transfer
Energy Movement
Students study energy movement. Energy always moves somewhere.
Heat Transfer
Students study heat transfer. Heat moves by conduction, convection, and radiation.
Light Transfer
Students study light transfer. Light travels in straight lines.
Sound Transfer
Students study sound transfer. Sound needs a medium to travel through.
Electrical Energy
Students study electrical transfer. Electricity carries energy along wires.
Motion & Forces
Motion
Students study motion. Motion is change of position.
Position
Students describe position. Position needs a reference point.
Direction
Students describe direction. Direction says which way something moves.
Distance
Students measure distance. Distance tells how far something moved.
Speed Introduction
Students meet speed. Speed relates distance to time.
Patterns of Motion
Motion Patterns
Students find motion patterns. Patterns make motion predictable.
Direction Changes
Students study direction changes. Forces change direction.
Speed Changes
Students study speed changes. Forces speed things up or slow them down.
Position Changes
Students track position changes. Position change is motion.
Cause and Effect
Students link forces to motion. Every change in motion has a cause.
Waves
What Is a Wave?
Students learn what a wave is. A wave carries energy without carrying matter.
Wave Patterns
Students study wave patterns. Waves repeat in regular patterns.
Energy and Waves
Students link energy and waves. Waves transfer energy.
Light Waves
Students study light waves. Light travels as waves.
Sound Waves
Students study sound waves. Sound travels as pressure waves.
Sound
Sound
Students study sound. Sound is energy travelling as waves.
Vibrations
Students study vibrations. Sound comes from vibrating objects.
Sound Sources
Students identify sound sources. Every sound has a source.
Pitch
Students study pitch. Pitch describes how high a sound is.
Volume
Students study volume. Volume describes sound strength.
Light
Sources of Light
Students identify light sources. Light sources make their own light.
Natural Light
Students study natural light. The Sun is our main natural light.
Artificial Light
Students study artificial light. People make light with lamps.
Light Travel
Students study how light travels. Light travels in straight lines.
Reflection
Students study reflection. Light bounces off surfaces.

Teaching Methodology
Our Grade 4 Science classes are investigation-led and evidence-based. Students design fair tests, measure with real tools, graph their results, and explain their conclusions using evidence. Most units include something they can try at home with safe everyday materials. Students learn through:

Standards Note
Grade 4 Science learning in Illinois is guided by the Illinois Learning Standards for Science, which incorporate the Next Generation Science Standards and describe expectations across life science, physical science, earth and space science, and engineering design.
Illinois schools and districts may organise science instruction differently and may use different textbooks, kits, instructional materials, pacing guides, technology, activities, and assessments. The exact sequence and depth of topics may vary by school or educational provider.
This syllabus represents a broad Grade 4 Science pathway designed to support Illinois science learning expectations. It is not the only Grade 4 Science syllabus available, and no specific textbook, kit, assessment, software, or instructional resource is required statewide.
Content on adaptations, ecosystems, Earth processes, and human impact on the environment is presented factually as established science, at a level appropriate for this age group.
All hands-on activities are designed to use safe, everyday materials and should be carried out with adult supervision. Students are taught electrical and heat safety, never to look directly at the Sun, and to protect their hearing during sound investigations.
It is important to distinguish between the Illinois science learning standards and the course structure created for this educational programme, which organises science into a month-by-month teaching sequence.
