New York Science — Grade 3
Comprehensive Course Syllabus
Course Overview
Our New York Grade 3 Science course follows the three big Grade 3 storylines of the New York State Science Learning Standards: forces and interactions, inheritance and variation of traits, and weather and climate — all taught through hands-on investigation.
The physical science strand covers forces, motion, balanced and unbalanced forces, magnets, and an introduction to electricity. Children investigate patterns of motion and learn to predict what a force will do — then test whether their prediction was right.
The life science strand covers plant and animal life cycles, traits, inheritance, variation, adaptations, habitats, ecosystems, and food relationships. Children learn that offspring resemble their parents but are never identical, and that traits suit organisms to where they live.
The Earth science strand covers weather, weather patterns, climate, water and Earth systems, natural hazards, and Earth materials. Running through the whole year is engineering design — defining problems, testing solutions, and improving them — alongside scientific models, data, evidence, and STEM projects.
Scientific Inquiry & Investigation
What Is Science?
Children learn that science explains the natural world using evidence. Science asks questions and tests answers.
Scientific Questions
Children frame questions that can be investigated. Testable questions make science possible.
Observations
Children observe carefully and systematically. Observation is the foundation of all science.
Predictions
Children predict outcomes before testing. Predictions must be based on reasoning.
Evidence
Children use observations as evidence. Evidence supports every scientific claim.
Science Tools & Measurement
Rulers
Children use rulers accurately. Rulers measure length in standard units.
Measuring Length
Children measure length in customary and metric units. Length is the most common measurement.
Balance Scales
Children use balance scales. Balances compare mass directly.
Measuring Mass
Children measure mass in grams and kilograms. Mass measures how much matter is present.
Thermometers
Children read thermometers accurately. Thermometers measure temperature.
Patterns in Science
What Is a Pattern?
Children learn that a pattern is something that repeats predictably. Patterns allow prediction.
Identifying Patterns
Children find patterns in observations. Pattern finding is a core science skill.
Repeating Patterns
Children recognise cycles that repeat. Repetition is what makes a pattern.
Patterns in Motion
Children find patterns in how things move. Motion patterns allow prediction.
Patterns in Weather
Children find patterns in weather records. Weather patterns support forecasting.
Forces & Motion
What Is a Force?
Children learn that a force is a push or a pull. Forces change how things move.
Pushes
Children investigate pushing forces. Pushes move objects away.
Pulls
Children investigate pulling forces. Pulls move objects closer.
Motion
Children describe motion precisely. Motion means changing position.
Direction
Children describe direction of movement. Direction is part of describing motion.
Motion & Patterns
Position
Children describe where an object is. Position needs a reference point.
Distance
Children measure how far something travels. Distance is measured along the path.
Direction
Children record the direction of travel. Direction distinguishes different motions.
Fast and Slow
Children compare speeds. Comparison needs the same distance or time.
Straight Motion
Children investigate motion in a straight line. Straight motion is the simplest case.
Balanced & Unbalanced Forces
Balanced Forces
Children learn that balanced forces cancel out. Balanced forces do not change motion.
Unbalanced Forces
Children learn that unbalanced forces change motion. Unbalanced means one side wins.
Equal Forces
Children investigate forces of equal size. Equal opposing forces balance.
Unequal Forces
Children investigate forces of different sizes. The larger force determines the result.
Starting Motion
Children see that starting motion needs an unbalanced force. Objects at rest stay at rest otherwise.
Magnets & Magnetic Interactions
Magnets
Children explore what magnets do. Magnets attract certain materials without touching.
Magnetic Materials
Children identify magnetic materials. Only some metals are magnetic.
Nonmagnetic Materials
Children identify non-magnetic materials. Most materials are not magnetic.
Attraction
Children investigate magnetic attraction. Opposite poles attract.
Repulsion
Children investigate magnetic repulsion. Like poles push apart.
Electricity & Interactions Introduction
What Is Electricity?
Children learn that electricity is a form of energy. Electricity powers most modern devices.
Sources of Electricity
Children identify where electricity comes from. Power stations and batteries are the main sources.
Batteries
Children learn that batteries store energy. Batteries make portable devices possible.
Simple Circuits Introduction
Children meet the idea of a complete circuit. A circuit must be a closed loop.
Conductors Introduction
Children learn that some materials carry electricity. Metals are good conductors.
Engineering Design
What Is Engineering?
Children learn that engineers solve practical problems. Engineering applies science.
Identify a Problem
Children define the problem clearly. A clear problem makes a solution possible.
Define Criteria
Children decide what success looks like. Criteria let solutions be judged.
Identify Constraints
Children identify limits on the solution. Constraints include materials, time, and cost.
Brainstorm Solutions
Children generate several ideas. More ideas mean better options.
Engineering & Forces
Designing Moving Objects
Children design objects that move. Design applies force knowledge.
Ramps
Children investigate ramps and slopes. Steeper ramps produce faster motion.
Wheels
Children investigate how wheels help motion. Wheels reduce resistance to movement.
Rolling Objects
Children investigate rolling. Rolling is easier than sliding.
Pushing and Pulling
Children apply pushes and pulls in designs. Both forces have design uses.
Plant Life Cycles
Seeds
Children examine seeds and their parts. Seeds contain a tiny plant and food.
Germination
Children observe seeds beginning to grow. Germination needs water and warmth.
Seedlings
Children observe young plants. Seedlings grow rapidly with light and water.
Mature Plants
Children observe fully grown plants. Mature plants can reproduce.
Flowers
Children examine flowers and their role. Flowers are the reproductive part.
Animal Life Cycles
Animal Birth
Children learn how animals begin life. Some hatch from eggs, others are born live.
Growth
Children observe animals growing. Growth follows predictable stages.
Development
Children observe animals developing. Development changes body form and ability.
Adult Animals
Children study adult animals. Adults can reproduce.
Reproduction Introduction
Children meet the idea of reproduction. Reproduction continues the species.

Teaching Methodology
Our Grade 3 Science classes are investigation-led. Children predict, test, measure, record, and explain — using evidence rather than memorised facts. Students learn through:

Standards Note
This syllabus is aligned broadly with the New York State P-12 Science Learning Standards (NYSSLS) for Grade 3. It is designed to explain clearly to parents and students what Grade 3 science covers.
New York State schools, districts, and charter schools may use different textbooks, science kits, curriculum programmes, pacing guides, laboratory resources, and assessment systems. This syllabus does not claim that every New York school follows the same programme.
This is not the only official Grade 3 Science syllabus in New York. It is one structured pathway through the Grade 3 standards, created for this educational programme.
It is important to distinguish between the New York State Science Learning Standards and the course structure created for this educational programme, which organises those standards into 32 teachable modules.
