Lesson 4: "Inventing" the Subsystem Concept
http://www.fossweb.com/modules3-6/LeversandPulleys/index.html Use the activity to identify an entire system and see how each subsystem affects the outcome of the entire system. (Needs to have Shockwave installed.)
http://www.rube-goldberg.com/html/gallery.htm Examine images of "Rube Goldberg" machines. These machines depict one system with a number of subsystems. The machines are typical of old cartoons.

Lesson 13: Liquid and Solid Butyl Stearate
http://iknowthat.school.aol.com/AOLAtSchool/matter/science_desk.html Use this interactive simulation to show how water changes from liquid to gas to liquid to solid.
http://www.bbc.co.uk/schools/scienceclips/ages/9_10/changing_state_fs.shtml Allows students to change a block of ice into liquid, solid, and gas then observe the changes.
http://www.bbc.co.uk/schools/scienceclips/ages/9_10/gases_fs.shtml Students can see how matter changes and observe the changes to see that the amount of material stays the same.
