Grade 7 Unit: Heat and the Environment

Introduction
Science within the classroom is a phenomenal subject unlike any other. It
allows the student to view both objectively and subjectively observable events that
based on opinion can seem significant or insignificant. Remarkably, it seems that as
we view science all around us and we focus on recreating a lot of the environmental
and universal phenomenon through our classroom teaching and demonstrations. A
major feat that is constantly being spun about the wheel of change and reform is the
innovation of technology and its implications on shaping the framework of the
world we live in today. The unit within the grade 7 curriculum to focus on these
changes is Heat and the Environment.
Every year global warming is getting worst in every part of the world. That
we experience here also in Canada. Summer is getting hotter and hotter every year
and result a drastic change in our environment. Grade 7 will have a deeper
understanding of how heat affects the world and everything on it. The study will be
focused in the topics of cause and effect of heat, investigating properties of heat,
relate it to geological and meteorological processes, and use their new-found
knowledge to design a device to minimize heat transfer. Practical theory will be use
for explain some observation.
Safety will be one of the concerns of the subject the students will be required
to explain safety practices for themselves and other people. This includes the proper
handling of hot objects and protecting themselves from heat and objects that are

heated. Students will utilize their learning both inside and outside of the classroom;
however, safety will be paramount concern throughout all lessons.

Culminating Task Overview:
Throughout the unit of Heat and the Environment, students have been working on a
number of different concepts including the movement of particles when given energy,
understanding the states of matter when heat is applied and the transfer of energy
through the methods of convection, conduction and radiation. As a culminating task it is
challenging to try to encompass all of these elements. However, the task chosen will
reflect upon the greater understanding and implications of these principles on the world
at large and practical application scenarios. The following will look at both
environmental impact on waste and material consumption in addition to the viability of
maintaining heat, minimizing loss to the environment. As I’m sure many teachers' can
attest to, caffeine is a very large component of the morning routine in the form of
coffee and tea. The students will be required in this task to design and develop a new
coffee mug that will be able to hold a hot liquid to the best of the materials ability
without causing heat transfer to the hand holding the mug or escaping to the
surrounding environment. Environmentally, this will serve as a method of eliminating
undue waste from multinational corporate products such as McDonalds, Starbucks, Tim
Horton’s…etc. Although most companies have taken recycling initiatives, the process is
lengthy and financially consuming. Thus, the benefit of undertaking this culminating task
will not only increase student awareness of global environmental and economic issues,
but also reinforce concepts relating to thermal design, heat transfer and specific heat
capacities of different materials. The students will be assessed on their ability to recall
and reinforce concepts attained throughout the unit. In addition, application questions
will provoke further thinking by asking the students to understand the economic
feasibility of reproducing their mug on a greater industrial scale for consumer
purchasing and reflect upon these practices. Furthermore, understanding the concept of
Grade 7 Unit: Heat and the Environment
14
energy transfer through to the Earth by means of waste production will be reinforced in
cross-curricular areas of biology and ecological sustainability. These subjects will be
revisited later on in the science curriculum.
Curriculum Expectations:
OVERALL EXPECTATIONS
By the end of Grade 7, students will:
1. Assess the costs and benefits of technologies that reduce heat loss or heat-related
impacts on the environment;
2. Investigate ways in which heat changes substances, and describe how heat is
transferred;
3. Demonstrate an understanding of heat as a form of energy that is associated with the
movement of particles and is essential to many processes within the earth’s systems.
SPECIFIC EXPECTATIONS
2.5 use a variety of forms (e.g., oral, written, graphic, multimedia) to communicate with
different audiences and for a variety of purposes (e.g., design a multimedia presentation
explaining the interrelationships between biotic and abiotic components in a specific
ecosystem)
3.5 describe how matter is cycled within the environment and explain how it promotes
sustain- ability (e.g., bears carry salmon into the forest, where the remains decompose
and add nutrients to the soil, thus supporting plant growth; through crop rotation,
nutrients for future crops are created from the decomposition of the waste matter of
previous crops)
3.8 describe ways in which human activities and technologies alter balances and
interactions in the environment (e.g., clear-cutting a forest, overusing motorized water
vehicles, managing wolf-killings in Yukon)
1.1 assess the social and environmental benefits of technologies that reduce heat loss or
transfer (e.g., insulated clothing, building insulation, green roofs, energy-efficient
buildings)
2.1 follow established safety procedures for using heating appliances and handling hot
materials (e.g., use protective gloves when removing items from hot plates)
2.4 use scientific inquiry/experimentation skills (see page 12) to investigate heat
transfer through conduction, convection, and radiation
Grade 7 Unit: Heat and the Environment
15
2.5 use appropriate science and technology vocabulary, including heat, temperature,
conduction, convection, and radiation, in oral and written communication
2.6 use a variety of forms (e.g., oral, written, graphic, multimedia) to communicate with
different audiences and for a variety of purposes (e.g., using the conventions of science,
create a labeled diagram to illustrate convection in a liquid or a gas)
3.3 use the particle theory to explain the effects of heat on volume in solids (e.g., rails,
sidewalks, and bridge segments expand in hot weather), liquids (e.g., sea levels are
rising partly because global warming is making the oceans warmer and the water in
them is expanding), and gases (e.g., the air in car tires expands on hot pavement)
3.4 explain how heat is transmitted through conduction (e.g., the transmission of heat
from a stove burner to a pot and from the pot to the pot handle), and describe natural
processes that are affected by conduction (e.g., the formation of igneous and
metamorphic rocks and diamonds)
Required Materials:
For this experiment, the instructor should supply as many materials as possible to
alleviate student time searching for resources and focus on the primary goal of
completing the assignment. Students are welcome to add or supplement materials they
hypothesize will yield better results. The following should be provided:
 A number of mugs of various materials (ceramic, glass, Styrofoam…etc)
 Materials to be used as insulators (cloth of different makes (polyester, cotton,
nylon, fur))
 Tape, scissors, glue and other craft material necessary
 Kettle to boil water
 Water outlet
 Thermometers
 Stopwatch (used to record the time of maintaining heat within the mug)
Students are required to have:
 Lab handouts with culminating activity procedures
 Pens, pencils and other writing instruments
 Extra paper for data recording
Teacher Guide for Procedures:
The culminating task may take 3-4 class periods depending on length of time allotted on
that particular day of study. Students should first work on developing their design of the
mug and thinking of the resources they which to use for their experiment. Secondly, the
Grade 7 Unit: Heat and the Environment
16
students will move to the design and implementation phase where they will build the
mug. Finally, students will assess their work and analyze the data collected from the
experiment. Conclusions will be drawn and submitted for assessment purposes. The
students will work on the project in the following procedural steps to maximize
efficiency and productivity:
Step #1
Students will be given the handout stating their objective. They will work in partners or
groups of three to enhance collaborative efforts and increase socialization within the
assignment.
Step #2
Students will use one class period to come up with a design for their mug with a writeup explaining their methodology and reasoning for the materials used and design of the
m mug. The reasoning will be based from prior lessons in the classroom, information
from field trips, notes and other texts supplementing the subject area.
Step #3
Once designed and built, the mug will undergo stress tests using hot water to test for
heat transfer to the environment around it. Pouring the hot water into the mugs and
checking the temperature of the water within them over a period of calculated time
intervals will do this. Students will observe, record the data and calculate their
conclusions and errors.
Step #4
Students will then present their mug and findings to the rest of the class in an oral
presentation using a form of multimedia, prezi, power point, Google doc…etc. to
illustrate their findings and correlations to other products on the market currently.
Step #5
If time permits, students can use additional class time to work artistically on their
project and make it more marketable to the consumer if they have not already done so.
Prior Knowledge:

 Students need to have a signed safety form along with a signature from their
parent or guardian in relation to the lab.
 Students will be working with water, which is a hazard for slipping if spilled onto
the floor. Precautions will be taken to ensure that they will not run in the
classroom.
 The water will be boiling so there is a chance of burning. Students will be advised
before the lab begins on the procedure of how to handle burns and that the
teacher should be notified immediately.
Grade 7 Unit: Heat and the Environment
18
 Students will be working with scissors and other tools for development of their
mug. These tools possess a risk for cuts and scrapes. A first aid kit will be present
in the classroom at all times and students will be familiarized with its location
and contents.
 Students are to advise the teacher immediately if there are any incidents that
occur within the classroom, no matter how minor.
 Records should be maintained of any injuries and constant communication be
maintained with the appropriate students body, parents and office staff.

Unit Test Overview:
After thorough studying the unit of Heat and the Environment, students will be
assess through a written test that will measure what they understand and how will
they apply it in their daily living. The students will answer questions from the topics
about the causes of heat changes in solids, liquids and gases. They will also impart
the important role of heat in nature. And heat technologies offer benefits but require
proper use so it will not cause bad effect in the environment.
Curriculum Expectations:
OVERALL EXPECTATIONS
By the end of Grade 7, students will:
1. Assess the costs and benefits of technologies that reduce heat loss or heat-related
impacts on the environment;
2. Investigate ways in which heat changes substances, and describe how heat is
transferred;
3. Demonstrate an understanding of heat as a form of energy that is associated with
the movement of particles and is essential to many processes within the earth’s
systems.
SPECIFIC EXPECTATIONS
1.1 assess the social and environmental benefits of technologies that reduce heat
loss or transfer (e.g., insulated clothing, building insulation, green roofs, energyefficient buildings) Sample guiding questions: (a) Insulated clothing protects our
bodies and increases our ability to enjoy outdoor activities in winter. What science
and technology concepts are at work in coats designed for use in cold weather? Who
might be interested in such designs? (b) A wellinsulated home is more comfortable
and costs
less to heat. Reducing heat loss saves energy, and saving energy reduces the
environmental impact of energy production. What are some areas of your home
where heat might be lost? How can this heat loss be counteracted? What are the
benefits of doing so? (c) Green roofs save on heating and cooling costs and reduce
the amount of insulation that is needed. But they have not gained wide acceptance in
Ontario. What might be some deterrents to having a green roof? How might these
deterrents be overcome? (d) Energy-efficient buildings are extremely airtight
compared to conventionally constructed buildings. This minimizes the amount of
Grade 7 Unit: Heat and the Environment
27
warm (or cool) air that can pass through the structure. What are some of
thedisadvantages to having airtight buildings (e.g., lack of fresh air, moisture
buildup)? How can these problems be solved (e.g., through mechanical ventilation
systems with heat recovery and humidity control), and how effective are the
solutions?
1.2 assess the environmental and economic impacts of using conventional (e.g.,
fossil fuel, nuclear) and alternative forms of energy (e.g., geothermal, solar, wind,
wave, biofuel) Sample issues: (a) Your family is building a new home. Present a
case for installing a geothermal heat pump. In your discussion, be sure to include the
benefits and costs from both an environmental perspective and an economic
perspective. (b) Make a case for (or against) using rural land or marginal land-use
areas for wind turbine farms..
2.1 follow established safety procedures for using heating appliances and handling
hot materials (e.g., use protective gloves when removing items from hot plates)
2.2 investigate the effects of heating and cooling on the volume of a solid, a liquid,
and a gas
2.3 use technological problem-solving skills (see page 16) to identify ways to
minimize
heat loss
Sample problem: Use the materials provided to create a product (e.g., a model of a
piece of winter clothing, a model of a wet suit, a model travel mug for a hot beverage
or food item) that will minimize heat loss
2.4 use scientific inquiry/experimentation skills (see page 12) to investigate heat
transfer through conduction, convection, and radiation
Sample problem (conduction): After letting spoons made of different materials sit
partially submerged in a container of hot water, measure the temperature of the
parts sticking out of the water. What conclusions can you draw from your findings?
2.5 use appropriate science and technology vocabulary, including heat,
temperature, conduction, convection, and radiation, in oral and written
communication
2.6 use a variety of forms (e.g., oral, written, graphic,multimedia) to communicate
with different audiences and for a variety of purposes (e.g., using the conventions
of science, create a labelled diagram to illustrate convection in a liquid or a gas)
3.1 use the particle theory to compare how heat affects the motion of particles in a
solid, a liquid, and a gas
3.2 identify ways in which heat is produced (e.g., burning fossil and renewable
fuels,
Grade 7 Unit: Heat and the Environment
28
electrical resistance, physical activity)2. Developing Investigation
aommunication Skill1. Relating Science and Technolog
3.3 use the particle theory to explain the effects of heat on volume in solids (e.g.,
rails, sidewalks, and bridge segments expand in hot weather), liquids (e.g., sea
levels are rising partly because global warming is making the oceans warmer
and the water in them is expanding), and gases (e.g., the air in car tires expands
on hot pavement)
3.4 explain how heat is transmitted through conduction (e.g., the transmission of
heat from a stove burner to a pot and from the pot to the pothandle), and
describe natural processes that are affected by conduction (e.g., the formation of
igneous and metamorphic rocks and diamonds)
3.5 explain how heat is transmitted through convection, and describe natural
processes that depend on convection (e.g., thunderstorms, land and sea breezes)
3.6 explain how heat is transmitted through radiation, and describe the effects of
radiation from the sun on different kinds of surfaces (e.g., an ice-covered lake, a
forest, an ocean, an asphalt road)
3.7 describe the role of radiation in heating and cooling the earth, and explain how
greenhouse gases affect the transmission of radiated heat through the atmosphere
(e.g.,The earth is warmed by absorbing radiation from the sun. It cools by
radiating thermal energy back to space. Greenhouse gases absorb some of the
radiation that the earth emits to space and reradiate it back to the earth’s
surface. If the quantity of greenhouse gases in the atmosphere increases, they
absorb more outgoing radiation, and the earth becomes warmer.)
3.8 identify common sources of greenhouse gases (e.g., carbon dioxide comes from
plant and animal respiration and the burning of fossil fuels; methane comes
from wetlands, grazing livestock, termites, fossil fuel extraction, and landfills;
nitrous
oxide comes from soils and nitrogen fertilizers), and describe ways of reducing
emissions
