Start off your program by giving some basic information about what participants can expect to learn. Introduce the topic and provide a basic outline of what's to come using videos, images, and text.

Anything that occupies space and has mass is called matter. Matter can be classified in different ways : (i) One of these classifications is as naturally occurring materials and man-made materials, (ii) The other way of classifying matter is in three states, i.e., solid, liquid and gas. The idea that all substances contain incredibly small moving particles is called the kinetic theory of matter. The word ‘kinetic’ comes from a Greek word meaning moving. The main points of the kinetic theory are: (i) All matter is made-up of tiny, invisible, moving particles. These particles are actually atoms, molecules and ions. (ii) Particles of different substances have different sizes. (iii) Small particles move faster than larger particles at the same temperature. (iv) As the temperature rises, the particles possess more energy and move around faster. (v) In a solid, the particles are very close and they can only vibrate about fixed positions. (vi) In a liquid, the particles are further apart. They have more energy and they can roll around each other. (vii) In a gas, the particles are far apart. They move very fast and randomly in all the space they can find.

Start off your program by giving some basic information about what participants can expect to learn. Introduce the topic and provide a basic outline of what's to come using videos, images, and text.

Break down your content into manageable steps. Use videos, images, and text to explain your main points, and set clear expectations and goals. You can also include files and audio as additional resources. Consider adding a questionnaire to ask participants what they hope to take away from the experience, or a quiz to test their understanding before getting started.
