Basic 9 Science Notes

Open a topic to read the notes, copy the key parts into your notebook and do the exercises.

Term Preparation

  1. Preparing for the Term in ScienceIn this topic you will prepare for the term by recalling key ideas in science, reviewing investigative skills and planning how you will observe, investigate, record and present findings.

Materials

  1. Binary Chemical CompoundsIn this topic you will identify binary chemical compounds by name, discuss their uses and explain how they are formed.
  2. Acids, Bases, Salts and Chemical BondsIn this topic you will describe the characteristics of common acids, bases and salts, and recognise that chemical bonds result from the attraction between atoms in a compound.

Living Cells

  1. Specialised Cells in Plants and HumansIn this topic you will discuss specialised cells and how they are formed in dicotyledonous plants and humans, and examine the functions of specialised plant cells.
  2. Specialised Animal CellsIn this topic you will examine the structure and functions of specialised animal cells, such as nerve cells, blood cells, muscle cells and sperm cells, and discuss their roles in the body.

Earth Science

  1. The Nitrogen CycleIn this topic you will explain the process of the nitrogen cycle as a repeated pattern in nature, and describe the importance of the nitrogen cycle to the environment.

Life Cycles of Organisms

  1. The Life Cycle of the GrasshopperIn this topic you will describe the life cycle of the grasshopper as a form of incomplete metamorphosis, and examine how grasshoppers affect human beings.

Human Body Systems

  1. The Circulatory SystemIn this topic you will explain the concept of the circulatory system, state the function of each part and discuss the health challenges associated with it.
  2. Respiration and BreathingIn this topic you will explain the concept of respiration, and show how the respiratory and circulatory systems complement each other.

Energy

  1. Conserving Energy and Calculating Energy UseIn this topic you will list ways of conserving energy, explain the importance of energy conservation in daily life and calculate the electrical energy consumed over a period of time.

Term Project

  1. Term Project: Investigating in ScienceIn this topic you will apply the term's learning through science project work, using observation, investigation, recording and presentation of findings.
  2. Term Project: Presenting and RevisingIn this topic you will present your science project, and revise the term's topics in preparation for assessment.
