as presenter.
2. Get from your teacher the materials to be used in the activity.
3. Listen to the instructions to be given by your teacher.
4. The leader will get the materials.
5. Classify each material according to properties such as Hardness,
Brittleness, malleability, ductility, flexibility, porosity, density,
thermal conductivity, Solubility, Viscosity and Chemical Reactivity
(The different substances are written on a strip of paper placed
inside the envelope)
6. Report the prepared output to the class.
