Grade 3 Science
100% Free for Schools, All School Year
From forces and magnets to ecosystems, life cycles, and weather, our Grade 3 science courses turn big questions into engaging, screen-based discoveries.
Real Science Thinking, Made Approachable
Students build genuine scientific reasoning skills: observing, predicting, testing, and explaining, through interactive lessons designed just for 3rd-grade learners.
Learn Anywhere, On Any Device
All that's needed is an internet-enabled device and an individual student account. Courses run smoothly on desktops, laptops, Chromebooks, and tablets.
Virtual Labs That Feel Like the Real Thing
Kids don't just read about science — they experiment with it. Interactive simulations let students test variables, observe results, and draw their own conclusions.
Learning That Feels Like Play
Mini-games reinforce every lesson's concepts, turning review into something kids actually look forward to.
Built-In Progress Checks
Five review questions close out every lesson, and each course wraps up with a printable 15-question assessment — giving teachers a clear picture of understanding along the way.
Free for Your Whole School, All Year Long
No licensing fees, no per-student costs — just sign up and give every classroom full access to the entire Grade 3 science curriculum for the whole school year.

Force and Interactions
- 5 lessons
What makes things move? Students explore pushes and pulls, balanced and unbalanced forces, friction, and magnetism — testing their ideas through two virtual labs in every lesson. They’ll predict how objects move, compare forces, and discover how magnets attract and repel.
Topics: Pushes and Pulls · Balanced and Unbalanced Forces · Friction · Force Strength and Direction · Magnetism
Relationships in Ecosystems
- 7 lessons
How are living things connected to each other and their environment? Students dig into food chains, food webs, adaptations, and the ripple effects of environmental change — including how humans impact the ecosystems around them.
Topics: Ecosystems · Interdependence · Food Chains & Food Webs · Ecosystem Balance · Adaptations · Environmental Changes · Human Impacts
Life Cycles and Traits
- 7 lessons
Why do offspring look like their parents — but not exactly? Students trace the life cycles of plants and animals and uncover how inherited traits, variation, and environment shape every living thing’s chances of survival.
Topics: Living Things · Plant & Animal Life Cycles · Inherited Traits · Trait Variation · Environmental Influences · Adaptations
Weather and Climate
- 8 lessons
What’s the difference between weather and climate — and can you predict tomorrow’s forecast? Through virtual labs simulating real-world conditions, students explore temperature, humidity, and air pressure, and see how these combine to create rain, snow, and storms.
Topics: Weather & Climate · Weather Measurement · Weather Patterns · Clouds & Precipitation · Extreme Weather · Climate Zones · Weather Forecasting
