The document discusses the properties of different materials and an activity to observe these properties. It defines soluble and insoluble materials as those that do or do not mix with water. An activity is described where different substances are mixed with water to see if they are soluble or insoluble. Materials can also float or sink in water, with sugar, salt, and sand sinking and wax, oil, and wood floating. Transparency is also discussed, with transparent, translucent, and opaque materials defined based on how much can be seen through them.

2. PROPERTIES OF MATERIAL
• SOLUBLE : Material that mix and become
invisible in water is called as Soluble .

3. PROPERTIES OF MATERIAL
• INSOLUBLE : Materials that do not mix with
water and are still visible are called Insoluble .

5. PROPERTIES OF MATERIAL
• OBJECT THAT FLOAT OR SINK IN WATER
Sinking means object that goes below the water .
Floating means that float on top of water .
Some materials float in water while others sink:
Materials like sand, sugar and salt sink in
water.
Materials like wax, oil and wood float on water.

7. PROPERTIES OF MATERIAL
• TRANSPARENCY
• TRANSPARENT : Materials through which things can
be seen are called transparent. For example, glass, water,
air, test tube.
• TRANSLUCENT : Materials through which things are
only partially visible are called translucent. For
example, butter paper, old glass door.
• OPAQUE : Materials through which we are not able to
see are called opaque. For example, wood, iron, gold.
