Science for Kids
Browse K-8 science lessons built around observable phenomena, evidence, models, and systems thinking instead of trivia-only pages. Science is currently live for Kindergarten through Grade 8, with 37 topics and 120 worksheets.
What's Live in Science
Science is currently live for Kindergarten through Grade 8, with 37 topics and 120 printable worksheets. Use the grade hubs below to browse the sequence, or start with one of the stronger grade and topic entry points on this page.
The science library now covers Kindergarten through Grade 8 with live lessons, printable worksheets, practice, teaching guides, glossary support, and standards alignment. The sequence moves from observable needs, weather, and simple motion into ecosystems, Earth systems, matter, energy, engineering design, a Grade 6 bridge into cells, particle models, forces, and plate tectonics, a Grade 7 expansion into biodiversity, heredity, chemical reactions, and waves/light systems, and a Grade 8 extension into Newtons laws, energy transfer, chemistry models, and Earth history with climate evidence.
This subject hub works best when you want a cleaner entry into a science strand. You can start with living things and habitats, move into forces and weather systems, or use the Grade 5 through Grade 8 Earth, matter, and systems topics as a bridge into more formal middle-school science reasoning.
- Animal needs and weather observation in Kindergarten
- Plant growth, light and sound, and motion in Grade 1
- Habitats, matter, and weather in Grade 2
- Life cycles, adaptations, climate, and forces in Grade 3
- Energy, Earth processes, ecosystems, Earth systems, and engineering design in Grades 4 and 5
- Cells, particle models, forces, and plate tectonics in Grade 6
- Biodiversity, heredity, chemical reactions, and waves/light systems in Grade 7
- Newtons laws, energy transfer, chemistry models, and Earth history with climate evidence in Grade 8
Standards Snapshot
Science currently maps to 71 unique standards across NGSS.
Grade Spotlights
These are the strongest grade-level entry points in the live science library when you want a narrower place to begin.
Grade 1 Observable Science
Strong for plants, light, sound, and simple motion with concrete examples.
Open Grade 1 →Grade 3 Systems and Survival
A good transition into traits, adaptations, weather patterns, and forces.
Open Grade 3 →Grade 5 Earth and Ecosystems
Best for deeper systems thinking before middle-school science expands.
Open Grade 5 →Grade 6 Science Bridge
The strongest first middle-school science hub for cells, matter models, motion, and plate tectonics when students need a real evidence-and-model bridge.
Open Grade 6 →Grade 7 Systems and Evidence
A stronger middle-school set linking ecosystems, heredity, chemistry, and wave-based information systems.
Open Grade 7 →Grade 8 Physical and Earth Systems
The clearest pre-high-school science bridge for force laws, energy transfer, chemistry models, and climate evidence.
Open Grade 8 →Common Goals for Parents and Teachers
Use these entry points when you already know the skill or strand you want to support and need a clean starting page.
Teach plant growth with clear structures and observations
Use plant parts, needs, and growth support that still feels concrete to younger learners.
Open worksheet →Build ecosystem understanding before bigger systems work
Use habitats and ecosystem pages that connect living things, needs, and environmental change.
Open lesson →Support force and motion reasoning with models
Use Grade 3 practice to strengthen push, pull, friction, and balanced-force thinking.
Open worksheet →Move into Grade 5 systems science cleanly
Use food webs, matter cycling, Earth systems, and engineering design as stronger pre-middle-school anchors.
Open guide →Start middle school with evidence and systems thinking
Use Grade 6 topics that connect hidden models, Earth evidence, and physical interactions instead of isolated facts.
Open lesson →Extend middle school into Grade 7 with stronger science explanations
Use ecology, heredity, chemical reactions, and wave systems to keep science grounded in models, evidence, and cause-and-effect reasoning.
Open guide →Move Grade 7 models into Grade 8 systems science
Use Grade 8 force, energy, chemistry, and climate topics to deepen middle-school reasoning without drifting into thin survey content.
Open lesson →Use This Subject Hub When You Need To
The science subject hub is strongest when you want a phenomenon- and systems-based path through the library instead of a pile of disconnected topic pages. It helps families and teachers move from observations into models, evidence, and explanation across life, Earth, and physical science.
Featured Learning Paths
These short cross-grade routes group live topics that work especially well together, so the subject hub can guide progression instead of only listing pages.
Living Things and Habitats
Follow a life-science path from animal needs into plant growth and then broader habitat and ecosystem relationships.
Best for classrooms or families focusing on living things, survival, and environment connections.
Start this path →Weather, Earth, and Environmental Change
Move from simple weather observation into climate patterns, landforms, and ecosystem change across upper elementary.
Useful for learners who need a coherent Earth-science and environment sequence.
Start this path →Grade 5 Science Readiness Path
Use the strongest Grade 5 topics to support deeper system and cause/effect reasoning before middle school.
A strong bridge for students preparing for more formal middle-school science courses.
Start this path →Grade 5-6 Science Systems Bridge
Move from upper-elementary Earth and ecosystem reasoning into cells, motion, matter, and plate tectonics in Grade 6.
Best for students transitioning from upper-elementary science into middle-school explanation and modeling.
Start this path →Grade 6-7 Science Systems Bridge
Carry Grade 6 hidden-structure and Earth-system thinking into Grade 7 ecosystems, heredity, chemistry, and wave-based communication systems.
A strong path for students moving from Grade 6 science bridge topics into fuller Grade 7 systems and evidence work.
Start this path →Grade 7-8 Science Systems Bridge
Move from Grade 7 chemistry and wave models into Grade 8 force laws, energy transfer, chemistry structure, and Earth-climate reasoning.
A strong route for students moving from Grade 7 models and evidence into fuller Grade 8 physical and Earth-system reasoning.
