Lab – Identifying Mystery Gases (burning/glowing stint)
LESSON Description: Air is a mixture of gases, including nitrogen, oxygen and carbon dioxide.
All of the gases contain covalent bonds. Most of the gases in air are colourless and odourless.
Although these and other gases are indistinguishable in appearance, they exhibit different
chemical properties. These properties can be used to identify them.
Connection to CULMINATING ACTIVITY: Students will be given a handout to fill in
observations and discussion questions – this is testable material

AfL
Whole Class  PowerPoint presentation 30 mins
Go through examples on the board of chemical bonding
- PowerPoint – present material to whole group
If there is time:
- Present ions and ask how they would bond – if ionic
(which would be the anion or cation), if covalent (why?)
- Examples: Show the formation of ionic bonding in MgO
compound!
Consolidation and Connection
 Helping students demonstrate what they have learned
 Providing opportunities for consolidation and reflection

Use images and not just
works on powerpoint
Bold and underlnes
things that are key terms
or important things to
write down
Groups of 5  Let's Laugh About It (20 mins)
Help students remember the four different types of chemical
bonds by creating jokes about their characteristics.
1. Describe the four types of chemical bonds: covalent, ionic,
polar covalent, and metallic. Draw diagrams to illustrate
common compounds that have each type of bond.
2. As a class, create a four-way Venn diagram to compare
and contrast the characteristics of the four bonds.
3. Divide the class into pairs, and provide each pair with
chart paper and markers.
4. Have pairs create a joke to help them remember
something about each type of chemical bond. For example,
a joke might be: ''Why are covalent bonds good citizens?
Because they always share their electrons.''
5. Students should write their jokes on the chart paper.
6. When students are finished, have them share their jokes
with the class.
Extension/PREP/Hwk (activities completed outside of class to reinforce/extend
learning or prepare for next class)
AoL:
 See if the students understand
the terms of bonding enough to
make jokes in the periodic table

Accommodations/Special Needs: (this may have been identified above in DI section) How will you
accommodate for students with IEPs, ELLs etc.?
 Allowed to use their phones even IN PAIRS to make chemistry memes
 Can use google translate
Teacher Reflection on Lesson: (to be completed after teaching, you do not need to fill this out for
this assignment, just an FYI for reflective practice)
Aspects that worked:

It appears the first period class does well
with noise as well as silence – they are able
to sit down and work given clear direction
but prefer lecture based learning or lab work
Changes for next time:

 Have students present examples of Bohr
Rutherford Diagrams
 Examples in groups:
 Group 1: LiF, H2O, MgCl2, HCl, CH4, O2

LAB: IDENTIFYING MYSTERY GASES
INTRODUCTION:
Air is a mixture of gases, including nitrogen, oxygen and carbon dioxide. All of the
gases contain covalent bonds. Most of the gases in air are colourless and odourless.
Although these and other gases are indistinguishable in appearance, they exhibit
different chemical properties. These properties can be used to identify them.
Oxygen: Oxygen is essential for burning. Things burn more vigorously when they are in
pure oxygen than when they are in air, which contains about 20% oxygen.
Hydrogen: When hydrogen is ignited in air, the hydrogen atoms combine with oxygen
atoms to form molecules of water vapour. This rapid reaction is accompanied by a
characteristic “pop” sound.
Carbon Dioxide: Carbon dioxide does not burn and does not support combustion.
Carbon dioxide with extinguish a flame, making it useful as a fire extinguisher.
PURPOSE:
The purpose of this lab is to use the information on gas tests to identify different gases
produced in the reactions.

a test tube. Obtain a tiny amount of manganese dioxide powder on the blunt end
of a toothpick. Record 3 physical properties of the two reactants in the
observation table.
Light a burning splint using the Bunsen burner according to the instructions given
by your teacher.
Add the manganese dioxide to the hydrogen peroxide. Allow the reaction to
proceed for about 5 seconds, and note changes during the reaction in the
observation table.
Bring the burning splint close to the mouth of the test tube. If no reaction occurs,
blow out the flame and insert the glowing splint half way into the test tube.
Record your observations, and the result of the splint test in the observation
table.
