Objectives

1.  To acquaint children with the various changes that materials undergo.
2.  Students will participate in phenomenological activities illustrating various 
    changes of material. 

Materials needed

beakers
water
ice
hot plate
pictures

Recommended Strategies
                  
     Introduce the concepts of  "liquid" and "solid".  Students will pour water into 
a container from a beaker.  Ask the following questions: 

1. What does the water look like?
2. Can you pour it?
3. If we freeze it, will it still be a liquid?
4. Show an ice cube-observe the ice.
5. How did the water change?
6. Is it still water?

     Experiment:
     1.  Put an ice cube on your plate.  Sit it in a warm place.  Watch it to see 
         what happens to the ice. 

     2.  Record what happens by doing the cut and paste activity on a worksheet. 

     3.  Share the results using discussion and role playing activities.
