Science 10
General Outcome

Explain, using
the periodic table,
how elements
combine to form
compounds, and
guidelines for naming
ionic compounds and
simple molecular
compounds
WHICH INQUIRY STAGE(S)
1. planning + questioning
2. gathering + making sense
3. producing to show
understanding
4. communicating + reflecting
1.
P/Q
-Can be used as an
assessment tool just as
a calculator can be
used in a math test
ICT USED and HOW USED
(pedagogical techniques, logistics, responsibilities, technical preparations
groupings, troubleshooting...)
Mini lesson and reading on: naming ionic and molecular
compounds (using rules and subscripts in particular: a review by
the time you are working from Alberta Science in Action text book
section A3.4 The Mole), then a review of the periodic table (can be
projected from the app screen)
ICT Used: AtomCalc (“The AMC App”)

G/M
Specific Outcome

Calculate
molar masses of ionic
and molecular
compounds
ICT ROLE IN
ASSESSMENT
BACKGROUND to the LESSON:
Students often find calculation of molar mass
difficult. This app can act as a scaffold and is also a
good way to review how to interpret chemical
formulae.

PRIMARY DATA THAT WAS
-None
AtomCalc’s purpose is to calculate molar masses of any
compound. The user enters the molecular formula by pressing the
cell for each element by the number of that element’s subscript in
the compound. In addition, the percent by mass of each element
is indicated. Any exercise in learning or calculating molar masses
(whether learning it for the first time or preparing standard
solutions for doing a lab) can see this app being applied.
An example exercise might be:
Calculate the molar mass of lead (IV) sulfate ( Pb(SO4 ) 2 )
The student should realize that each formula unit of lead (IV)
sulfate has one lead atom, two sulfur atoms, and 8 oxygen atoms.
If they do not remember that, then this app could act as a review
for the appropriate use of subscripts. On AtomCalc they would
then enter
PbSSOOOOOOOO [Calculate] and would be given the result.
AtomCalc could be used in a test situation as an aid and skill test
simultaneously.
REFLECTIONS ON ICT AS A FUTURE LEARNING TOOL
-Past what I have described, AtomCalc has limited further
application.
