BASIC SET

The MYLAB Science Small Scale Set provides a unique way to do the
practical work in Chemistry and Natural Science at school from Grade
4 – 12.
The set has the following properties:
• The set is a true-to-life small-scale laboratory (test tubes, spatula,
deflagrating spoon, etc.). All reactions, colour changes and products
are clearly visible. The apparatus can easily be heated and cooled.
• All experiments are done with small amounts of chemicals –
cutting costs, pollution and the danger of explosions.
• Preparation of solutions by the teacher is limited to the minimum
– match-head quantities of solids are dissolved to generate
solutions of workable concentrations.
• The set can be used in an ordinary classroom; hence, no
laboratory is needed. No electricity or running water is needed
for the experiments. Very little storage space is needed – quite a
number of sets can easily be stored in a classroom.
• The set is constructed of durable materials – with a long life
expectancy (stainless steel and polyethylene).

Do experiment to answer the problem question.
Example of a
Worksheet
Experiment 2 (Grade 10)
Problem Questions:
How can you use Chromatography to separate dye colours in watersoluble inks?
Core knowledge and concepts:
Matter and Materials
Learning Outcome 2:
Constructing and applying
scientific knowledge
Assessment Standards:
(AS1, AS2, AS3)
•
•
•
Recalling and stating specified concepts.
Indicating and explaining relationships.
Applying scientific knowledge.
By the end of this lesson, the learner should be able to:
Observe phenomena, describe concepts, classify and use materials
(macroscopically).
Apparatus: 1x MYLAB apparatus stand, 1x beaker stand; 1x watch
glass, 3x test tubes, filter paper, 1x spatula,
1x propette and 1x glass beaker.
Chemicals: Tap water
Extra:
Colour ink pens (water soluble) – red, brown and orange
WARNING be careful when you work with glass apparatus.
Activity
1:
Which separation technique can be used to determine what
colour mixture each of the water-soluble ink pens (red, brown and
orange) contain?
Method:
•
Fill the glass beaker with about
50 ml of water or use a test tube
and 5 ml water.
•
Place filter paper 1 with the red
circle over the beaker (or test
tube) so that the tip of the rolled
filter paper is in the water and
acts as a capillary tube. (M)
What
you know already:
(i) Recognise the difference between a mixture and a chemical
compound:
A piece of shiny iron is left in the rain and after two days, its colour
changes to brown. Is the product formed a chemical compound
or a mixture?
(K)
Chemical compound.

Educational
Advantage
•
•
•
It will enhance the attitude of both teachers and learners towards
Chemistry/Natural Science as a subject and establish a positive
climate of learning.
This kit will give access to laboratory opportunities, resources,
knowledge acquisition and conceptual development. It will contribute towards socio-economic development.
A website of MYLAB is available to support facilitators and learners.
