SEEd - Grade 6
Strand 6.2: Energy Affects Matter 6.2.2
2 class periods of 45 minutes each
This is a model where the students act as molecules to show the arrangement of particles in the 3 states of matter. An extension is done to show the motion of the particles relative to the state, and how temperature also affects motion and arrangement. This activity can be done by having class discussion and drawings on the board or using the more detailed student sheet.
Ask how the student particles could represent real particles and take up as little space as possible. Take some ideas, and end up having them squeeze together touching shoulders.
Ask how the student particles could represent real gas molecules and take up as much space as possible. Take ideas, and end up having them spread out as far as possible so no one is touching.
Ask how the student molecules could represent real liquid molecules & be close but not too close. Take ideas, and end up having them spread out, but need to be within arms reach of other student particles.
Extension to 3 a & b: 30 min (students would do this all day if you let them, especially if you let them take turns being in charge) 15-20 min. is needed for students to fill out paperwork.
Discussion Break: Fill in diagrams and discuss questions and ways to mend the model to be more accurate. (You may want to remind them that previously solids were close enough to be touching shoulders, and liquids were within arms reach) Possible corrections: solids will not take up the whole room, but student molecules: are only in 1/2 of the room, or need to be touching shoulders. In this case, they will end up making several solid clumps
