States of matter_l12

California Science Standard
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.

Content Objectives
After 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 & gases
4. Compare and contrast the energy and motion
of molecules in solids, liquids & gases

Language Objectives
After 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.
