Super Safety in Science!

Learning Objective: How can we be safe in science?

Safety in Science

Safety in science lessons

How to stay safe in science lessons

Students must not enter a laboratory without permission

Sensible and safe behaviour is expected at all times

Be angelic!

Students must not eat or drink in a laboratory

You might get

poisoned!

Apparatus must not be touched or used without permission

You might damage

it!

Bags and coats must be stored safely

or, you might trip over them!

Goggles must be worn and long hair tied back when instructed

All accidents and damage must be reported immediately to the teacher

All apparatus must be returned carefully and safely after practical work

It keeps the technician

happy!

Bench surfaces must be clean and dry at the end of the lesson

Obey any instructions given by a member of staff

They may stop you

from doing something

silly!

Hazard Signs and their meanings

You need to know what all these symbols mean to keep you safe in science.

Harmful

These chemicals are similar to toxic chemicals but are less dangerous.

An example of a harmful chemical is

Potassium permanganate.

Irritant

These chemicals cause redness or blistering of the skin.

An example of an irritant is

Glycerol.

Oxidising agent

These chemicals help other chemicals to burn more fiercely.

An example of an oxidising agent is

Hydrogen peroxide.

Corrosive

These chemicals attack and destroy living tissue including the eyes and skin.

A example of a corrosive chemical is

Sulphuric acid.

Toxic

These chemicals can cause death.

They may have their effects when swallowed, absorbed through the skin or breathed in.

An example of a toxic chemical is

Mercury.

Flammable

These chemicals catch fire easily.

An example of a flammable chemical is

Methylated spirit.

Radioactive

These substances can cause burns and cancer.

An example of a radioactive substance is

Uranium.

Harmful to the environment

These chemicals will damage plant or animal life.

An example of this is

Copper (II) sulphate.

Super science diagrams

Learning objective: How can we show another scientist what equipment we have used and how to set it up?

Diagrams You need a sharp

pencil, ruler and a pen.

Diagrams should be 2D and drawn with a pencil and a ruler and not shaded.

You should always fully label a diagram.

The names of the equipment should be written in pen.

Measuring volumes of liquids.

Learning objective: How can we measure the volume of liquids?

Can you measure liquids precisely?

Anagrams

Which pieces of equipment could we use to measure liquids?

How can we measure volume?

Units = cm3

Reading volumes

You get a more accurate reading if you bend down so that your eye is level with the liquid in the measuring cylinder.

Precise reading

If you look carefully at the liquid in a tube, it seems to go up at the sides of the tube. The curved shape it makes is called the meniscus. You should take your reading from the bottom of the meniscus.

What is the volume?

Fill the container with the different liquids.

Tip them into the measuring cylinder. Read off the volume that the container

holds. Record your results in your booklet.

Measuring Temperature.

Learning objective: How we measure temperature?

How can we measure temperature?

Thermometer safety rules

Never put a thermometer down where someone can knock it off the bench.

Make sure your thermometer has a safety ring fitted.

If you break a thermometer, ALWAYS tell your teacher. Do not try to clear it up yourself.

Magnesium and acid Measure 10cm3 of

acid into the test tube.

Take the temperature, write down your result.

Add your magnesium strip.

Take the temperature every 30 seconds.

Have a go!

Can you read the thermometers on your worksheet?

Measuring Time!

• Learning Objective: How can we measure time?

• What are some different units of time?

What are the units of time?

Days

Hours

Seconds

Minutes

Years

Milliseconds

Grams

Kilograms

Degrees

Meters

Centimetres

Newtons

How can we measure time?

Units = seconds

How do you use a stopwatch?

You need to know how to start, stop and re-set.

How long does it take you to move 20m?

How long does you shape take to fall to the bottom of the measuring cylinder?

Measuring mass.

• Learning objectives: How can we measure mass?

• Can you read some different masses and use the correct units?

How can we measure mass?

Units = kg

How do we use measure mass in science?

What is the mass? Which piece of equipment has the

highest mass? Which piece of equipment has the

lowest mass?

Can mass change in chemical reactions?

Measure 20cm3 of acid into the conical flask and put it on the balance. What is the mass?

Add a spatula of chalk. What do you observe?

What happens to the mass?

Learning objective: Can you use all the skills you have used to carry out this practical?

How to draw a science table and a science graph.

Starter Can you find the missing words? Do you know

what they mean? Collect What something is measured in. Equipment Write it down. Experiment Information in a clear way. Measure Look, listen, hear and smell. Observe Information from an experiment. Record What you use in an experiment. Results Get something. Table To read from a piece of equipment. Units Practical in science.
