Equipment
Here is some common equipment used in science lessons. You will need to be able to use this equipment
properly.

Measuring Accurately
You must make sure that you measure any readings accurately.
Measuring Liquids
When you need to measure an exact volume of a liquid you use a measuring cylinder.
You get a more accurate reading if you
bend down so that your eye is level with
the liquid in the measuring cylinder.
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.
How much liquid is in these measuring cylinders?

What rules do you think we should have in the science classrooms to ensure that all students are
safe?

HAZARD SYMBOLS: DO YOU KNOW WHAT THEY MEAN?
Match the symbol to its correct meaning:
Radioactive, Toxic, Harmful/irritant,
Dangerous for the Environment, Oxidising, Corrosive, Highly Flammable, Explosive
Label the Bunsen burner using the words below
* Air Hole
* Base
* Chimney
* Collar
* Flame
* Rubber tubing
Sort these steps to light a Bunsen burner into the correct order.
Quickly light the gas with the splint
Turn the collar to get the correct flame for the experiment
flame for the experiment
Close the air hole completely
Place the Bunsen burner onto a heatproof mat
Light a splint
Turn on the gas tap
Put on your eye protection
Once a flame appears from the Bunsen burner, move your hand away completely
move your hand away quickly
Attach the rubber tubing firmly onto a gas tap
Say briefly what the following safety apparatus is used for in the lab:
Safety blanket:

Complete the blanks:
What will happen between the dependent and
independent variables?
What do you notice about your results? What
do they show you?

Task: You need to complete 3 investigations which require a bit of thought in
order to get an accurate answer. The investigations are: Finding the mass of
100ml of water, finding the mass of 100ml apple juice and 100ml milk.
Describe fully how the apparatus will be used, control of variables and
how the practical will be kept fair.
Hint: You just want the mass of the liquids.
Initial method - How do you think you can achieve this?

Safety
BUNSEN BURNER SAFETY
Aim: Fill in the blanks to help you remember the safety procedures for
using a Bunsen burner
(TIP: Always spell Bunsen with a capital B because it is named after the
inventor Robert Bunsen)
1. Whenever I start a practical involving fire, chemicals or sharp objects I
must always put on my S _ _ _ _ _ G _ _ _ _ _ _ first.
2. When using a Bunsen burner it must always be placed on top of a H _ _ _
P____ M__.
3. Before turning on the Bunsen Burner you must make sure that the air
hole is C _ _ _ _ _ so that you get a Y _ _ _ _ _ safety flame.
4. The area around the Bunsen burner must be clear so that nothing can
catch F _ _ _.
5. When lighting a Bunsen burner you must always use a lit S _ _ _ _ _ and
hold it over the Bunsen burner before turning the gas tap on.
6. When you start heating something you need to open the air hole to get a
B _ _ _ roaring flame so that you don’t get black soot from the safety
flame (this makes things harder to clean afterwards and the roaring
flame is a lot hotter so it will heat the object up much quicker)
7. When the experiment has finished I must turn the Bunsen burner off by
turning off the G _ _ T _ _ and not blowing out the flame.
8. I must leave the Bunsen burner equipment (Bunsen burner, heat proof
mat, tripod, gauze, beaker etc) for at least 5 minutes before clearing it
away because it will be H _ _ !
9. Congratulations, you can now safely use a Bunsen burner!
