States of
MatterLesson 1
Standard 3: States of Matter: Standard 3D: Students know
the states of matter (solid, liquid,
gas) depend on molecular motion.
California Science Standard
Standard 3: States of Matter: Standard 3E: Students know that in solids the atoms are closely locked in position and can only vibrate; in liquids the atoms and molecules are more loosely connected and can collide with and move past one another; and in gases the atoms and molecules are free to move independently, colliding frequently.
California Science Standard
Content ObjectivesAfter this lesson I should be able to:1. Name the three states matter can exist in.2. Compare and contrast the properties of solids,
liquids and gases.3. Compare and contrast the arrangement of
molecules in solids, liquids & gases4. Compare and contrast the energy and motion
of molecules in solids, liquids & gases
Language ObjectivesAfter this lesson I should be able to:1. Read and listen to a lecture and write
Cornell notes.2. Watch a video and write the main
ideas.3. Write a list of common solids,liquids
and gases.
