Discover how science works.
Ask questions. Investigate ideas. Explain what you discover.
Explore middle school life, physical, Earth and space science through clear explanations, observable examples and evidence-based thinking. Choose a grade pathway or begin with a simple investigation.

Science for every middle school stage.
Explore age-appropriate ideas and questions. These are suggested learning pathways, not a complete grade-by-grade NYS curriculum sequence.
Grade 7
Discover connections.
Explore ecosystems, energy transfer and the ways forces and environmental changes affect systems. Use models to explain cause and effect.
Explore Grade 7 Science →Grade 8
Build scientific arguments.
Explore motion, waves, Earth history and the evidence scientists use to support explanations. Practice comparing competing claims.
Explore Grade 8 Science →Explore the subject
Four ways to see the world.
Science connects everyday observations to bigger questions. Start with a field that sparks curiosity.
Life science
Living things and ecosystems
How do organisms get the resources they need? How do living things interact with one another and their environments?
Practice observing evidence →Physical science
Matter, forces and energy
What causes motion? How can energy move through a system? What clues reveal a physical or chemical change?
Investigate a variable →Earth & space science
Our changing planet
What shapes landscapes? What drives weather patterns? How do observations help us understand Earth and space?
Learn to use models →Scientific practices
Questions, models and evidence
Ask testable questions, plan investigations, analyze information, and explain how evidence supports a claim.
Try the mini-investigation →GENIUS PRACTICE · SCIENCE
Can you spot the variable?
Imagine a student puts identical ice cubes on two different surfaces to see which melts faster. The cubes start at the same size, and both surfaces are in the same room.
Question
What changes?
The surface underneath each ice cube: one metal, one wood. This is the variable the student deliberately changes.
Measurement
What do we observe?
Measure the time each cube takes to melt. Record the results instead of guessing what will happen.
Fair comparison
What stays the same?
Keep the starting ice-cube size, room conditions and measurement procedure as consistent as possible.
Check your thinking
Which is the dependent variable—the result being measured?
Choose an answer to see why it works.
This is a thought experiment for identifying variables; melting rates can depend on material properties and additional conditions. Adult supervision is recommended for any hands-on activity.
How we learn science
Make every explanation stronger.
Ask
Begin with a question.
Turn an observation into a question you can investigate or explain with evidence.
Investigate
Collect useful evidence.
Make measurements, compare observations and track which conditions changed.
Explain
Connect claim and evidence.
Tell what the evidence shows, why it matters, and what you still do not know.
