Team Members: Sheila McKinnon, Sandra Broomes and Angela Scott

Objective:

The main objective of the Mini-teach is to show primary & intermediate students 
the three states of matter.

Materials:

One cube of ice
One sponge
Table top for each team
Timer (clock)
Work Sheet

Strategy: 

Give each team an ice cube.  Have the students use what ever they can to melt 
the ice cube, timing from when they receive it.  When finished, be able to 
determine the states of matter by reporting what had happened and how they 
melted their cube.  Then students must hypothesize what happens to the water 
after they wipe it off the table.  
 
Performance Assessment:

3 points--Understand the three states of matter.  Can tell you that the water 
left by the sponge went into the air as water vapor. Was able to verbalize and 
write the process.
2 points--Understood the three states of matter.  Was able to verbalize only 
the solid and liquid.
1 point--Understood the three states of matter.  Was unable to verbalize any of 
the process.
