1. Ask students to list some examples of objects with lustre.

2. Ask students to list some soft and hard objects around them.

3. Ask for five examples each, of objects that float and those that sink in water. What about testing these same materials to see if they float or sink in other liquids like oil? Ice is denser than water but it floats. Why?

4. Ask the students to list out some transparent, opaque and translucent objects.

5. Make a paper boat. Place it in water. Watch it float and write your observations.
