SAFETY IN THE LABORATORY - DO YOU KNOW ?

Rules to Follow:


First Aid For Accidents:

Eye injuries can be caused by liquids splashing into your eyes during experiments. Always wear your safety glasses. Also never point a test tube towards your face or anyone else's.

Poisoning can be caused by breathing in fumes during an experiment, eating chemicals or by spilling them onto your skin. Do not eat or drink in the lab.

Cuts are caused by broken glass, so make sure any broken glass goes into the labelled bin.

Burns can be caused by touching hot equipment, or by spilling hot liquid when someone bumps you. Treat burns with cold running water. Serious burns can occur with a Bunsen burner. If this happens, tell your teacher at once.

Fires are always possible when using burners. It is essential to tie back long hair whenever you are using a burner.

Damage to clothing and skin can occur when chemicals especially corrosive liquids such as acids and alkalis, are spilt. If there is a spill, wash the area immediately with lots of water and send someone to tell the teacher. In the most serious cases you may need to use the safety shower.

Damage to the laboratory can occur when sinks become blocked with paper or solids, which can cause flooding if the taps are left running. The benches can also be scorched during heating. They can also be damaged by chemical spills, so wipe these up immediately.

MEASUREMENT SKILLS

The process of science involves observation, investigation and testing. Scientific observations can be made directly with our own senses or may be made indirectly through the use of equipment to collect data. Being able to take accurate measurements is important. The units and type of equipment used depends on whether you are measuring length, volume, temperature or mass. 

1kg  = 1000g      1m= 100cm   1000mm=1m     10mm = 1cm                1min = 60secs

Volume- is a measure of the amount of space an object occupies

1000ml = 1l

READING THE MENISCUS CORRECTLY

DIFFERENT METHODS OF SCIENTIFIC INVESTIGATION

1) PATTERN SEEKING 

2) MODELLING 

3) fair testing 

In a fair test you should only change the independent variable!

4) researching 

5) identifying and classifying 

THE SCIENTIFIC METHOD

TYPES OF VARIABLES in a fair test experiment

GRAPHS AND TABLES

Tables and graphs are visual representations used to collect, record and anlyse data. They are used to organise information to show patterns and relationships. A graph shows this information by representing it as a shape. Researchers and scientists often use tables and graphs to report findings from their research. In newspapers, magazine articles, and on television they are often used to support an argument or point of view. 

VARIABLES ON A GRAPH

The independent variable makes the x-axis (horizontal line) of the graph and the dependent variable makes the y-axis (vertical line). 

TYPES OF GRAPHS

A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent.  

2. LINE GRAPHS

Line graphs are used to track changes over short and long periods of time. 

3. HISTOGRAM

is a graphical display of data using bars of different heights
