Warm up
(5 – 10)
Activity
Date: 11-15 October 2015
Main Activity
( 30 mins)
Key vocab
The teacher
Excess, limiting
distributes
reactant
pictures
representing
common
commercial
reactions. The
teacher discusses
with the students
the ways of
increasing the
products. This will
lead to the
importance of
stoichiometric
calculations in our
everyday life.
Objectives
Teaching and classwork
1. Solve
stoichiometr
ic equations
(mass-mass
problems).
The students are going to
solve the mass- mass
problems depending on
their pre-knowledge of the
relationship between mole,
Ar and Mr.
Plenary
(5 -10 mins)
The students
are going to
construct a
thinking map
representing
the steps of
solving massmass
problems.

designed to have
questions of different
DOK levels.

HA; these students can
distinguish between the
volume of 1 mol gas at
STP conditions and
SATP conditions
The teacher pauses the
video to discuss the
concept with the students
and to solve problems
within the video.
The teacher distributes a
worksheet on percentage
yield. The students are
going to solve the
problems in groups.

The students deduce from
the video, the meaning of
STP conditions and will
know that 1 mol of any gas
occupies 24 dm3 at these
conditions.
The teacher distributes a
worksheet on molar
volume to the students to
solve in groups.
From the starter activity,
the students will be able to
give definitions for
empirical and molecular
formulae.
The students
construct a

The teacher will show the
students the proper steps
for calculating empirical
and molecular formulae of
compounds using
experimental data. The
steps for solving such
questions depend on the
students' previous
knowledge.
