Discussion
Brief Introduction
The materials that surround us may be classified as solid, liquid or gas. Solid
are materials with definite size and shape. Solids have different properties and
characteristics. But these materials can also undergo change when they are
exposed to temperature or when they are mixed with other materials.
Learning Competency to be developed:
Classify materials based on their properties and uses
Objectives:
At the end of this activity, learners should be able to
1. Identify materials based on the ability to absorb water, float, sink
and undergo decay
2. Describe materials based on the ability to absorb water, float,
sink and undergo decay
3. Appreciate materials that can absorb water, float, sink and
undergo decay
A. Let’s Recall
Look for the following materials inside your house. Classify the materials according
to the state of matter. Put a check mark on the appropriate column.

ACTIVITY 1
Using the materials you have searched inside your house, get the sponge or
rug, cotton, rubber ball, stone and paper. Do the following steps.
1. Get a basin or pail with water.
2. Drop the materials one by one on the basin or pail.
3. Observe what happen to the different materials.
4. Lift one material and try to squeeze.
5. Do the same thing for each material.
6. After lifting the last material, put all the materials on the basin and clean the
working table.
Fill in the table below with the observations made on the activity. Put a check
() if the material absorbs water and cross (x) if it does not absorbs water
Materials

ACTIVITY 2
6
Using the materials you have searched inside your house, get the
plastic bottle with cover, rubber ball, stone and styrofoam. Do the following
steps.
1. Fill the basin or pail with water
2. Gently drop the plastic bottle with cover
3. Observe what happen on the plastic bottle
4. Lift the plastic bottle then drop the next material.
5. Observe what happen to the material
6. Do the same with the rest of the materials
7. After lifting the last material, put all the materials on the basin and
clean the working table
Fill in the table below with the observation made on the activity. Put a check
() if the material floats and cross (x) if it sinks
Materials
Check or Cross

ACTIVITY 3
Using the materials you have searched inside your house, get the left
over food, juice, and stone and do the following steps.
1. Describe the appearance of each materials. Write the observations
on your notebook
2. Place each material on a container then add ¼ glass of water
3. Cover each container and make sure that it is placed in an area that
gets equal parts of shade and sunlight.
4. Observe the set-ups every day.
5. Record your observations and findings

C. Lets Explain
There are materials in the environment that can absorb water and
materials that cannot absorb water. When water is absorbed, the material
naturally or gradually takes in water. A material that is a natural absorber of
water is cotton because it is very porous. Porous means having small holes
that allow air or liquid to pass through. Rubber ball and stone did not absorb
water because they are non-porous materials. Non-porous materials does not
have holes that allow air or liquid to pass through.
There are some materials that float. Float means to stay on the top while
other materials sink. Sink means to fall to the bottom of the water. There are
materials that float and sink very fast while other materials float and sink very
slowly. The shape, size and weight of a material affects their ability to float or
to sink. Styrofoam, balsa and ship can float no matter what their shape, size or
weight is.
But there are also materials that float first then after gradually
absorbing water, will also sink.
Plants and animals does not decay at the same time. Decay is to be
slowly destroyed into bits in the presence of water, air and soil. Fuel is a byproduct of decaying. When a material decays over a long period of time, it will
be converted into fossil fuels such as oil, coal and natural gas.
Materials that decay on soil makes it more fertile over a period of time.
The decomposed organism will mixed with the soil and becomes organic
fertilizer. Sunlight, water, soil and action of microorganisms are factors that
contribute to the decaying process.
Decaying process may be delayed by exposing the material to a lower
temperature. Left over foods can still be eaten and can delay spoilage if it was
kept on a refrigerator because microorganisms cannot grow fast on a cold
8
temperature.
The presence of molds, bubbles, worms and foul smell are
indication that the material in on decaying process.
