8 Physics Properties Of Matter

# Schedule

Oct 7 - Oct 31 (3 weeks)

# Instructional Objectives

Students should be able to understand:

• Three states of matter
• Atomic theory of matter
• Kinetic theory of matter
• Inter and intra molecular forces (cohesion and adhesion)
• Arrangement of molecules and general properties of three states of matter.
• Change of phase
• Conduction and Convection
• Surface tension in liquids - Formation of meniscus and shape of liquid droplets
• Liquid pressure and its measurement using manometer
• Pressure exerted by gas, effect of volume on pressure and its measurement by barometer.
• Archimedes principle, law of floatation and density.
• Water lift pump - working principle

# Teaching processes

• Starting with the question ‘what is the universe made up of?’ Make them realise that the list of things that they came up with, can classified as either matter or energy. Differentiate between them and introduce the definitions.
• Discuss the general properties of three states of matter we see around. Then analyse what are they made up of. Introduce the atomic theory and kinetic theory of matter and showing how these theories fit with observations.
• Explaining the transfer of heat in all the three states of matter with demonstration.
• Explaining the liquid properties such as surface tension and its application, liquid pressure and its measurement, Archimedes principle, law of flotation and density with demonstration
• Explaining the pressure exerted by gas and its relation to the volume, atmospheric pressure and its measurement, and water lift pump with demonstration.

# Support materials and special need modification

• Simple worksheets
• Familiarizing with new terms by making a list and ask students write a note about it.
• Sit with the student once a week and help him/her to write answers to the questions given in the textbook/ worksheets.

# Activities

• Surface tension - floating paperclip on the water surface.
• demonstrating capillary action
• Making a working model of barometer and manometer.
• Capillarity - Separation of pigments on the leaves
• Water pump making - working of valves
