UNIT- Being A Scientist
Duration: 7 weeks
Introduction
This unit will give students a general idea of who scientists are, what
they do, how they do it and checks and balances enforced by society
to make sure that the research carried out / information made
available are acceptable to society at large.
The Being a Scientist unit aims to:
 Provide a general idea of scientists past and present; their discoveries
and how these discoveries have helped humans.

knowledge acquired but also the fields available to them – careers that
they might consider in the future.

Living things in an ecosystem are called biotic (plants, animals,
predators etc) factors and non-living things are called abiotic (water,
rocks, soil, sun, weather) factors.
Habitats must provide the things that animals and plants need to stay
alive (food, water, shelter, space, reproduction etc)
Producers, consumers (carnivores, herbivores) and decomposers rely
on each other in food chains and food webs
Predators and prey have ot fight for survival in different ways.
Animals are able to survive in harsh conditions due to their
adaptations

A wave is a manner of carrying energy from one place to another without a
net transfer of matter
Both light and sound are types of waves
Waves can be travel in a transverse and longitudinal manner
All rays and waves can be reflected
Angle of incidence is equal to the angle of reflection
Sound waves are made by vibrations
Sound is a transverse wave with regions of high and low pressure
Laws of reflection
Applications of mirrors
White light can be split into colours because different wavelengths
travel at different speeds
We see colours due to reflected and absorbed spectrums

Different colours can be combined to make white light
