Grade 8 – Science

About Course

The goal of this course is not to turn every student become a scientist, but rather to assist all students to develop two skills: scientific literacy and good attitudes about utilising science to obtain knowledge.

Students will be required to understand how to conduct scientific investigations, how to communicate the findings of scientific investigations to others, and how to apply their knowledge of science concepts and principles to reason about science and solve issues in real-life settings.

The goal of science education requires effective change in the context of teaching and learning.

This can only be accomplished by allowing students to investigate the background of science and its applications, as well as to build an awareness of the links between science, technology, society, and the environment.

Course Content

Chapter 01 – Human Organ Systems
An organ system is defined as a group of organs that work together to perform bodily functions. For example, the organs in the gastrointestinal (GI) system each play a unique, important role in food digestion.

Learn about sensitivity in animals.

04:49
Learn the coordination of organ systems in higher animals.

06:00
Learn the excretory system in animals.

04:22
Brain & Nervous System
QUIZ – Human Organ System

Chapter 02 – Heredity Organisms
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

Chapter 03 – Biotechnology
Biotechnology harnesses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet.

Chapter 04 – Pollutants and Their Effects on Environment
Air pollution can directly contaminate the surface of bodies of water and soil. This can kill crops or reduce their yield. It can kill young trees and other plants. Sulfur dioxide and nitrogen oxide particles in the air can create acid rain when they mix with water and oxygen in the atmosphere.

Chapter 05 – Chemical Reactions
A chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products.

Chapter 06 – Acids, Alkalis, and Salts
This chapter elaborates on the behaviour of acids, alkalis, and salts. Acids are generally colourless liquids or white solids.

Chapter 07 – Force and Pressure
Force is the push and pulls action and it results in the change of motion and direction. On the other hand, pressure is the physical force applied to the unit area of the surface.

Chapter 08 – Measurement of Physical Quantities
Measurements of physical quantities are expressed in terms of units, which are standardized values. For example, the length of a race, which is a physical quantity, can be expressed in units of meters (for sprinters) or kilometres (for distance runners).

Chapter 09 – Sources and Effects of Heat Energy
If the constituent particle of an object becomes excited by gaining energy, the particle moves or vibrates rapidly and the object is said to be hot. If the particles have less energy, they will not vibrate, and the object is said to be cold. Heat is the transfer of energy between these objects due to a temperature difference.

Chapter – 10 Lenses
Piece of transparent material (such as glass) that has two opposite regular surfaces either both curved or one curved and the other plane and that is used either singly or combined in an optical instrument for forming an image by focusing rays of light.

Chapter 11 – Electricity in Action
A fundamental form of energy observable in positive and negative forms that occur naturally (as in lightning) or are produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons, electric current or power.

Chapter 12 – Exploring Space
Space exploration is the investigation, using crewed and uncrewed spacecraft, of the reaches of the universe beyond Earth's atmosphere and the use of the information so gained to increase knowledge of the cosmos and benefit humanity.
