Play it Safe….
The job of a scientist
is to ask questions that have never been asked before, and that is when scientists need to find
the answers themselves by performing experiments. An experiment is simply a test on a small
part of the world.
Isaac Newton wondered why apples fell from a tree and spent many years of his life investigating
the forces of gravity. He later went on to study the solar system and the orbits of planets.
Scientists need to be able to use all of their five senses to make
observations. The main sense a scientist uses is sight, although hearing,
smell and touch are sometimes used.
‘Elementary dear Watson’ A scientist is really a detective trying to solve a puzzling case. They
gather clues (observations) and develop a conclusion from them.
Safety in science
In science you will deal with many potential dangers.
You will work with flames, intense heat and corrosive
substances like acids that can burn you badly.
It is particularly dangerous if chemicals like these get splashed in your eyes.
Lots of chemicals are poisonous
and can make you extremely ill or can kill you if you
sniff or taste them.
Broken glass and equipment can cut you or laboratory assistants. Glass is
particularly dangerous if it shatters, spreading fragments that can enter your eye.
Safety rules
The laboratory can be a very dangerous place, but can also be a very
safe one if we all follow some simple rules.
Mr Porker, the Science Laboratory Technician will provide you with a set of rules that you must
abide by when visiting the science laboratory. You will need to glue these rules into your
science book, learn them thoroughly and more importantly, follow them closely.
You will also be expected to draw a full page floor plan of your science laboratory
and on it, locate and label all relevant safety equipment.
How many rules are being broken in this image?
List them.
Now get creative. You should also select one science laboratory safety rule and produce an eye
catching A4 poster to hang in your classroom. You may prefer to write a poem instead or, if
you are clever enough and have the time, produce a short ‘looney tuney cartooney’. Discuss
your proposed plan of attack with your teacher before starting.
Eg.
Know Your Science Equipment
Here are some poster ideas that your teacher may wish to discuss with you.
