State of Matter - Atoms
Students examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.
Curated OER
The Nature of Matter
Students compare and contrast how the theory of atomic structure has changed over time. They explore how different people have contributed to our knowledge of the atom and its structure. Students identify how matter is made of discrete...

Review Sheet for Matter Test
In this matter activity, students answer five questions about the law of conservation of mass. They identify substances as solids, liquids, gases or mixtures and they identify given items as matter or energy.
Curated OER
Atom and Eve
Students research and define an atom using a concept map. They design and create a model of an atom, labelling all the parts, and write a journal entry.
