How can I make wise spending decisions about heat?
Financial Literacy
Introduction
Making financial decisions has become an increasingly complex task in the modern world; people need
knowledge in various areas and a wide range of skills in order to make informed decisions about financial
matters. They need to be aware of risks that accompany various financial choices. They also need not only
to develop an understanding of world economic forces, but also to become aware of ways in which they
themselves can respond to those influences and make informed choices. It is, therefore, essential that
financial literacy be considered an important attribute of a well-educated population so that Ontarians
may continue to prosper in the future. In response to a recognized deficit in financial skills in our students,
the Ministry of Education released Financial Literacy: Scope and Sequence of Expectations in 2011.
Ministry of Education – 2011
Knowledge and skills associated with financial literacy have always been important and are included in
these lesson packages. The lesson packages are designed using an issues-based approach and provide
supports for teachers to connect financial literacy education topics across the curriculum while teaching
the science and technology expectations. The lesson packages embed the core content and competencies
required for science and technology, and seamlessly fit STSE education and the skills of financial literacy.
Each issue was chosen with an economic component at its core. For instance, in the grade 9 applied
course, students are asked to explore the economics around replacing appliances in their homes.
The lesson packages are written using an issues-based approach and roughly contain the following phases
of lesson development:
1. Introduce the Issue
2. Determine Prior Knowledge
3. Engage Student Interest in the Topic
4. Build the Skills and Knowledge
5. Develop a Level of Concern
6. Take Action
From a financial literacy standpoint, the lesson packages help you to introduce discussion about the
effect of always wanting something new and how that impacts our ability to save and make wise financial
decisions. The issues-based approach is aligned with the organization of the curriculum documents.
Students will learn both science and financial concepts through the exploration of a relevant issue. The
lessons make use of a variety of approaches to address the multiple learning needs of our students. At the
end of the learning time, students will be expected to demonstrate their learning by taking action on the
issue in ways that recognize student readiness and ability to affect their surroundings.

Financial Literacy Lesson Planning
Minds On
Students will work in pairs and as a whole group to brainstorm ways to
conserve electricity in their homes. Their responses can be recorded on a
KLEW chart (see BLM #1.1).
Spark their interest.
1. Introduce the topic to students by playing the video clips featuring David
Suzuki explaining ways to make simple changes in our lives that will help
us conserve energy.
2. Direct students to focus on ways of conserving energy that they see in
the videos. Explain that they will have a chance to record their ideas after
watching the video clips.
The clips can be accessed from YouTube at:

Think - Pair - Share (self, partner, whole class)
Notes:
A KLEW chart is very similar to a KWL chart and the substitution may be
made if necessary. The titles in the KLEW chart are K- What we think we
know, L - What we have learned, E - What evidence we have, W - What we
are still wondering.
Students first list the things they think they know about the topic in the
K column. As the lessons progress, they can confirm their knowledge in
the L and E columns, by recording what they have learned to support their
knowledge and what evidence they use when learning (e.g., we could learn
by reading the Every Kilowatt Counts website) and the evidence is that what
we thought we knew was listed as one of the 25 tips.
At the end of this lesson series, students use the last column to list anything
that they are still wondering. The questions they generate could lead to
further investigations if time allows.

Students will work in small groups to sort a group of appliances from biggest
power user to least power user.
Assessment
1. Arrange students in groups of 4.
2. Provide each group with a copy of the appliance cards (BLM 2.1). Each
card has a picture of an appliance on the front and the power rating on
the back.
3. Ask students to spread the cards picture side up on the desk. Instruct
them not to look at the numbers until after they are done the sorting
task.
4. The cards should be sorted from smallest to biggest energy user based on
their previous knowledge.
5. Before giving out the correct answer, ask students to explain some of
their choices. (e.g., Why do you think that the hair dryer uses the most
energy?). Hearing some of their thinking provides crucial information
about student understanding.
6. Pass out an answer card so that students can check their answers.
Observe how students are arranging the
cards. What factors are they considering
during the sorting activity? Once sorted,
what errors did they make?
Differentiation
If the number of cards makes the activity
too difficult, have students only use the
pictures of cards for items that they use in
their homes. Have them sort this reduced
number of cards.

purpose. The rest of the energy is wasted when it is transformed into unwanted
forms of energy. For instance, a hair dryer uses electricity to produce heat to
dry our hair, but a lot of the electrical energy is turned into sound rather than
heat. The energy that goes into making sound is wasted making the appliance
less efficient.
1. Ask students to explore the electrical appliances in their world to see
how electrical energy is transformed. How is the electrical energy
intended to be used? How is energy wasted? Complete the table found
in BLM 2.2.
Financial Literacy Lesson Planning
12
Action (continued)
You could do this in two ways:
a. Students can take the observation table home and use appliances
they have around the house.
b. Use the Appliance cards from the first activity (BLM 2.1) and ask
students to reflect on any of the appliances from memory.
Is the same appliance made by different manufacturers more efficient?
2. Manufacturers often include a power rating on many of the devices
we use in our homes. You can use these labels to compare how much
power a device uses. You can also use the labels to compare two
similar devices and determine which device uses less energy - or is
more efficient.
The power ratings for a number of 32” LCD televisions are presented
in BLM 2.3. Students can analyze this data and compare similar
appliances to see which one uses the most power. Analysis questions
are included on the BLM to help students work through the data.
Keep in mind that while the television with the lowest power rating
would be the cheapest to operate, there may be other factors that
impact the buyer’s choice. (e.g., depending on the ambient light in
the room, a brighter picture on the television might be required and
would need more power to operate)
Consolidation
Watts Happened in the Past?
Assessment
Most families today use more energy for their daily activities than we did in
the past. In this writing activity, students will complete a compare and contrast
organizer (BLM 2.4) by reflecting on how we used energy in the past and how
we use energy today. (e.g., played board games in the past, play computer
games today).
Completion of the compare and contrast
organizer allows students to demonstrate
their ability to analyze the features of a
concept.
Writing the compare and contrast
Once students have completed the organizer, ask them to write a compare and paragraph provides an opportunity to

Financial Literacy Lesson Planning
Compare and Contrast
A compare and contrast paragraph is organized on the basis of the similarities and differences
between two objects or concepts. Students are often asked to compare two different things (ex.,
plants vs. animals) as a way of demonstrating their level of understanding. A graphic organizer is
a tool that can help students organize their thoughts before they begin writing. In addition to the
graphic organizer, students should also be provided with key words that can be used to link their
ideas together when they write.
Step 1 – Modeling
1. Start with a comparison that is
easy for all students to complete.
We want to stress the features of
the form, not the content (ex.,
skate boards and bicycles).
How Alike?
2. Start with a blank organizer
(overhead or poster) and describe
the areas of thegraphic organizer
to the students.
How Different?
3. Give students 1 minute to think
about how the objects are similar
or different.
With Regard To
4. Using student responses, fill in the
organizer.
5. Using the key words provided,
write a paragraph, as a class, that
compares a skateboard to a bicycle.

Ex., Compare and Contrast of a Skateboard with a Bicycle
Skateboards and bikes are alike because they both have wheels and are used for transportation.
Bikes have two wheels whereas skateboards have four wheels. When you ride a skateboard, you
stand on your feet, but when you ride a bicycle you sit on a seat. Skateboards are different from
bikes in the way that you steer. Bikes have handle bars while skateboards are steered by shifting
your weight from side to side. Both bikes and skateboards are fun to ride.
Step 2 – Guided Practice
1. As part of a future lesson,
select another pair of objects
or concepts that students
could easily compare. Your
choice this time need not be
arbitrary, but could come from
course material.
2. Organize students into pairs
or small groups. Provide each
group with a blank graphic
organizer.
3. Students should first think
of answers on their own,
then work with their group
to complete the graphic
organizer.
4. The group should write a
paragraph that explains the
differences and similarities
between the two objects

Lesson 3 - What information is on a hydro bill?
Throughout this five part lesson series, students will
• learn about electricity consumption and how to reduce their consumption at home and school,
• examine home hydro bills and explore the variations in cost and the factors that impact the cost of the bill,
• examine the use of electricity at school through the exploration of light use throughout the day,
• examine the cost savings of conservation using an online calculator to determine savings of money, KWH, and
carbon when conservation strategies are utilized.

Description Summary
Connections
Students will complete an on-line questionnaire evaluating their use of
electricity at home, based on their habits. Students will then examine a
sample hydro bill to increase their general knowledge about hydro bills
and assess factors that impact the hydro use and resulting cost within a
household.
What is my Electric Personality?

Action
Group Task
2. Provide students with a copy of the sample hydro bill (BLM 3.1).
3. As a group, examine the different elements of the hydro bill.
• Meter Information: Inform students that a meter reading is done
on the building’s meter to determine how much electricity the
building has used. The usage determines the cost of the hydro
bill. Determine the usage for this home.
• Billing Summary box: Discuss the important elements within
this box (previous balance, current amount due, interest charges
for late payment).
• Your Electricity Charges: This bill is for the month of May. There
are three separate billing costs (Summer Block 1, Summer Block
2, and Winter Block 1). The blocks are based on the seasons.
The cost or rate applied to hydro usage during the winter block
is less than both summer blocks. This hydro bill runs between
the end of the winter block and the beginning of the summer
block. Make note of the differing costs of the electricity and
then calculate the cost of hydro if all calculations were based
on one block only (i.e., 0.064 cents). Explore the differences
between the blocks. Discuss why the Hydro Company would
have differing rates for different seasons. Link the discussion of
the new Smart Meter programme and how it impacts the cost
of hydro (encourages use of electricity during off-peak times
which will reduce the cost of hydro to the consumer). Typical
time of use: off-peak: 7:00pm – 7:00am, mid-peak: 7:00am –
11:00am, and 5:00pm – 7:00pm, peak: 11:00am – 5:00pm.
• Electricity and Water Usage History: Examine the average daily
‘Electric Use’ (kWh) and discuss various elements that impact
the usage on the hydro bills, including: time of year, season,
temperature, appliance usage, holidays, working at home, size
of house, size of family). Have students determine the months
where the most electricity was used (Nov-Feb and July) to show
the impact of cold and hot weather on the cost of electricity.
Consolidation
4. Using BLM 3.2, students will read through two scenarios. The
scenarios present two different families and their use of electricity
during the day. When examining the use of electricity, students
should take into account the time of use rates as the family in
scenario one uses more electricity as compared to the family in
scenario two, but they also use more during peak hours, which
will result in a higher cost on the hydro bill.
5. Students will identify the behaviours that are costing the family
money. They will also identify the times at which consumption is
occurring and relate the times to the time of use graph.

How do different light bulbs use energy?
Assessment
All light bulbs transform energy into light, but depending on the bulb, a certain
amount of thermal energy (heat) is also produced. The next task is designed to
illustrate how much thermal energy is produced when an incandescent bulb Differentiation
and a compact fluorescent bulb are lit for 15 minutes.
2. Explain to students that light bulbs transform electrical energy into
light and heat. The energy that is transformed into heat is basically
wasted energy. Their task is to measure how much thermal energy
is released from two types of bulbs. We can compare the amount of
thermal energy by measuring the temperature change of trapped air in
an insulated box. Use the activity Testing Light Bulbs for Energy Waste
(BLM 4.1) to gather the information necessary.

Students will watch a video to set the stage for learning. Then students will use the website www.greenlearning.ca to
explore the cost of lighting a classroom/school and the impact of implementing electricity savings measures on the total
cost of the school’s hydro bill.
Follow the website prompts so that students can follow the instructions on the website to calculate the cost of using
all the lights in their classroom for the entire day. After calculating the base cost, students are given the opportunity to
suggest changes to how they use the classroom lights during the day. For example, they can modify how long they use the
lights, the type of bulb used, and how many lights are utilized. Students will use BLM 5.1 recording sheet to record the
cost of the lighting plan that is calculated based on the choices they make.
Introduction to Changing Light Bulbs
