Grade 5: Kitchen Chemistry
Kitchen Chemistry
You are the manager of your school’s cafeteria. Your cafeteria is coming up for
renewal of the permit to prepare and serve food to students. The Food
Preparation Quality Control Committee in your community has asked you to make a
presentation convincing them to renew your permit.
You are to create a poster a poster or construct a model to demonstrate the
ingredients and food preparation steps involved in the making of a nutritious pizza.
Your poster or model should highlight in some way the ingredients used in the
preparation of the pizza, the changes the ingredients go through, and what causes
these changes.
Your poster or model should include the following:
♦
♦
♦
♦
♦

♦
Labeled drawing or original uncooked ingredients and the finally prepared pizza
Ingredients used to make the pizza
How the ingredients address Canada’s Food Rules
Discussion of changes the food ingredients undergo as the pizza is prepared
Outline of whether the changes are chemical or physical and why
Discussion of whether the changes are reversible or non-reversible
One paragraph summary written to persuade the Committee to renew the
permit for your cafeteria

Grade 5: Kitchen Chemistry
This task addresses the following cluster of expectations. Expectations assessed by
the rubric are highlighted in bold.
Understanding Basic Concepts
•
•
•
•
identify and describe some changes to materials that are reversible and some that
are not (e.g., freezing and melting are reversible; burning is not)
describe changes they observe in the properties of materials when the materials
interact with each other (e.g., when paints are mixed; when water is combined with
gelatine)
identify the three different states of matter – solid, liquid and gas – and give
examples of each state (e.g., solid; sugar, rock; liquid: water, oil, gasoline; gas:
water vapour, air, oxygen)
describe, using their observations, non-reversible changes that occur when some
materials are heated (e.g., when paper is burnt; when an egg is cooked)
Developing Skills of Inquiry, Design and Communication
•
•
•
formulate questions about and identify needs and problems related to the properties
changes in state of familiar materials, and explore possible answers and solutions
(e.g., estimate and then measure the length of time certain foods take to melt when
heated; design a test to compare the insulating effects of different thicknesses of
foam polystyrene)
use appropriate vocabulary, including correct science and technology
terminology, in describing their investigations and observations (e.g., use
terms such as texture, hardness, strength, buoyancy, solubility, and flexibility
to describe properties of materials)
communicate the procedures and results of investigations for specific
purposes and to specific audiences, using media works, oral presentations,
written notes and descriptions, drawings and charts (e.g., make accurate and
detailed drawings of sugar crystals, as seen both with the unaided eye and
through a magnifying glass or microscope)
Relating Science and Technology to the World Outside the School
•
•
describe how physical and chemical processes change materials found at
home and materials used in industry (e.g., cooking, the manufacturing of
plastics)
describe physical changes and chemical reactions that can take place in
household products and explain how these reactions affect the use of the
products (e.g., the role of baking soda in cooking; the role of heat in cooking
an egg)
Grade 5: Kitchen Chemistry
Prior Knowledge Required:
Before attempting this task students should have been taught the following:
•
identify and describe some changes to materials that are reversible and some that
are not
• describe, using their observations, nonreversible changes that occur when some
materials are heated
Students should be familiar with the following science and technology terminology:
reversible, nonreversible, physical changes, chemical changes
Prior Skills Required:
Before attempting this task students should have experience of the following:
•
use appropriate vocabulary, including correct science and technology terminology, in
describing their investigations and observations (e.g., use terms such as texture,
hardness, strength, buoyancy, solubility, and flexibility to describe properties of
materials
Suggested Introductory Activities:
The following activities are suggested to introduce this task to the students:
•
•
identify the source of the materials found in a product (e.g., plastic is made from
petroleum) and describe the steps required to modify the natural materials to make
product;
describe physical changes and chemical reactions that can take place in household
products and explain how these reactions affect the use of the products (e.g., the
role of baking soda in cooking; the role of heat in cooking an egg);
Grade 5: Kitchen Chemistry
Cross-strand Links:
Every strand in the Science and Technology document has common set of expectations
clustered under the title Developing Skills of Inquiry, Design and Communication.
This task is therefore appropriate to assess and evaluate these skills for every Grade 5
strand. Links could also be made to the Life Systems strand. The expectations that
could be addressed are:
• describe the types of nutrients in foods
• interpret nutritional information to make healthy food choices
• identify types of industries involved in the processing and preservation of food
• describe the relationship between eating habits, weight, height, and metabolism
Cross-curricular Links:
This activity provides an opportunity for students to be assessed and evaluated on their
ability to work cooperatively as part of a group. Students should be made aware that
this will be an integral part of the evaluation and should have prior experience of
working with a group before being assessed. This provides a cross-curricular link with
The Ontario Curriculum Grades 1-8 Language, Grade 5: Oral and Visual
Communication - Group Skills. Links can also be made to The Ontario Curriculum.
Grades 1 to 8: Health and Physical Education Healthy Living: Grade 5. The
expectations that can be addressed are:
• explain the purpose and function of calories and the major food nutrients
If the students decide to produce a plasticene model a link can be made to The
Ontario Curriculum, Grades 1 to 8: the Arts, expectation from Visual Arts: Grade 5:
• produce two- and three- dimensional works of art that communicate a range of ideas
for specific purposes and to specific audiences
Reading and Writing Skills:
This task has been constructed to take into account the possible limited reading and
writing skills of some students at this grade level. At the end of Grade 5 students are
expected to be able to write a sentence (See MET Writing Exemplars 1999).
Depending on the achievement level of the children in the class and the time in the
school year that this task is administered, teachers will need to take into account the
diverse abilities in their classes. The task could be presented orally and evaluated
through teacher/student conferences. Teachers could use the questions on the student
task sheet to guide their conferences. Students could make oral presentations about
their investigation to the class. Their presentation could be based on the questions
outlined in the student task sheet. Grade 6 students could act as reading/writing
buddies to read out questions. A peer buddy system could be introduced.
Considerations for Combined Grade Classes
The overall and specific expectations for the strand, topic and performance task are not
well suited for combined grade classroom.
