• Observe that the sound is produced by the vibration of the matter,
• Observe that a medium is needed for sound to propagate
• Examines the relationship between the number of vibrations per unit time and the sound pitch produced,
• Examines the relationship between sound pitch and loudness.
7Ps.01 Describe the vibration of particles in a sound wave and explain why sound does not travel in a vacuum
9Ps.01 Draw and interpret waveforms, and recognise the link between loudness and amplitude, pitch and frequency.

In this experiment you will study the formation and propagation of sound. All sounds emanating from a sound source occur with the vibration of the particles in that sound source. Vibration is the back and forth movement of a particle in the medium. Vibration movement reaches our ears by propogating in the medium and we hear that vibration as sound. The vibration phenomenon that comes out of the source and reaches our ears is called a sound wave. In this experiment, you will also learn the concepts of loudness and sound pitch.
Observation of the planets and constellations, and information one sky maps.
Learn by combining the parts of the microscope and reading brief informative text. Observe the different types of the microscope and their differences
Distinguish acid and base with different indicators. Observe color changes when different reagents are used in acid and base substances.
MRI scanner possess powerful magnets to produce a strong magnetic field. This provides the doctors with cross-sectional images of the tissue.
