Students zoom in past what any microscope can see to meet the atom — the tiny building block of all matter — and learn how atoms join into molecules to make up everything around us.
Students will be able to…
If you cut a piece of gold in half, then half again, forever — what is the smallest piece you’d get? What is everything made of?
Project this and tap each part. Have students build an understanding of atoms, their particles, and how atoms join into molecules.
Tap any phase to open the teacher moves and student actions.
Cut something in half forever — what’s the smallest piece?
Students investigate.

Three quick checks.
Aligned to Next Generation Science Standards and Common Core literacy. State-standard crosswalks available on request.
Develop models to describe the atomic composition of simple molecules and extended structures.
Develop a model that describes changes in particle motion and state.
Gather information to describe that synthetic materials come from natural resources.
Integrate information presented in different formats to develop understanding.
Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.
Have students decode chemical formulas like H₂O and CO₂, counting how many atoms of each element are in the molecule. A printable formula sheet is in the Science library.
Tap a card to flip it, then rate whether you knew it. Built from this lesson’s vocabulary.
A quick self-check with instant feedback, drawn from this lesson’s key terms.
A print-and-go review sheet with a built-in answer key. Tap “Show answer key” to reveal answers, or print the clean version for students.
