Inquiry-Based Learning Lesson Plan

Objectives:

Analyse the changes in the states of matter through experiment.

Learning outcomes:

A student is able to :

1. explain the melting and freezing point based on the kinetic theory of matter.
2. relate changes in heat to changes in kinetic energy of the particles in matter.

Lesson Plan:

teacher will asked students:

1.Do you know how many states of matter in this earth? 

2.Do you know what is the melting point of water? 

3.What is the relationship of kinetic theory and the changes occur to matter?

4.Have you heard that the disintegration of ice is occurring in Arctic?Why would it occurred?

In this activity, student will work in groups (3 students per group) to study about the melting and freezing point of napthalene based on kinetic theory of matter through an experiment.  Student will be provided with the following materials and apparatus and they are required to build their own experiment. Students can discuss in their group and find information through books and internet. Teacher will guide them throughout the experiment.

Aim:

To determine the melting and freezing point of naphthalene and understanding of kinetic theory of matter

Materials provided:

Napthalene, C10H8

Apparatus provided:

Boiling tube

250 ml beaker

thermometer (0-100 Celcius)

Tripod stand

Retort Stand with Clamp

Bunsen Burner

Stopwatch

Conical flask

Wire gauze

At the end of the class, teacher will explained if there is any misconception about the kinetic theory of matter.
