Biology Chemistry Physics
Class 7 - Atoms, Elements & Compounds
Elements are the building blocks of all matter. The Periodic Table of Elements show all the 118 elements that make up all matter on Earth. Each element is made up of its own special type of atom.
Class 7 Ecosystems & Variation
Levels of organisation: An ecosystem is a community of living organisms (plants, animals and microbes) in relation with the non-living components of their environment (things like air, water and mineral soil), interacting as a system.
Class 7: Fitness
•Being fit can be defined as the ability of a body to cope with all the demands of its lifestyle. •Fitness is made up of four factors: 4 S-factors:
SI Units
SI units are an International System of units that are recognized and used in calculations by scientists world wide. Fundamental SI Units Derived units (from the fundamental units)
Class 7: Forces
•A force is a push or pull on a body. •Force causes motion: change in speed, direction, shape or size. •SI Unit of Force: Newton : N Types of forces:
Class 7 - The Particle Theory
The Particle theory formed due to hypothesis supported by evidence. The Particle Theory states that: All matter is made up of tiny particles The particles are moving all the time There are forces of attraction holding the particles together These forces vary in strength in different states of matter.

About Me

I have 5 years of experience in teaching Grade 7, 8 and 9 students biology, chemistry and physics. I give importance to planning well for my lessons and conducting them using a variety of teaching methods and resources. I aim to make my students understand the subject content so that they can be able to apply it to real life.
