Grade 8 |
Overview |
Recycling of materials is a great way to reduce the
waste from various areas. Land fills can breathe better which otherwise
are filled with toxicity . Recycling of biodegradable materials can give
rise to beautiful transformations. |
Learning standards
|
CBSC standards.
The students are made to know about different types of waste in and
around us.
The students are then made to analyze the substances and then separate
them into biodegradable and non-biodegradable substances.
The students are then brainstormed to give inputs on how the materials
are converted into different products.
|
Problem statement
|
The important facts students need to know
How is disposal become a perennial problem linked to pollution?
The ground water also gets polluted
What are some of the ways to address trash?
The students are brainstormed with their ideas to address this
problem.
|
Learning objectives:
|
Recycling and stems are very important for sustainable ecosystems and
to leave a better world for future generations. Recycling is a social
responsibility for all citizens for a sustainable society.
Understand that the recycling of biodegradable substances into new
products.
|
Materials |
Students will bring the substances which are
present in their own houses. |
Background Information: |
No simple, single solution exists to
solid waste management. The current thinking is that it should be an
integrated, seven-step process, including the 3RC process (the first
four steps), incineration (waste-to-energy), landfills and incineration
(no energy production). It is ideal to combine the first five of these
in such a way as to eliminate or at least drastically reduce the amount
of waste. |
EDP |
Engineers are involved in all steps of integrated-waste
management. They use smaller amounts of materials to package products as
discussed in the relevant activity |
Pre session (Teacher and material readiness)
|
Students can read through the article to understand what can be created
through recycling .

|
Process with time allocation:
|
The students are made to get different types of trash materials which
are present at home.
The students are divided into groups first to segregate them into
recycled materials and non–recycled materials.
Using the materials, the children will make various types of crafts
depending upon their thinking.

importance of waste management .
Engineering : The design
process.
Mathematics : Measurements of the design process
.
Technology: The biodegradable substances are recycled
into other useful products.
|
Results of the lesson |
Critical thinking:
students realize the problems and find the solution through
discovery.
2-Creativity and Cooperation: Students learn to
use their creativity, thoughts and imagination to reach a goal and solve
the problem.
3-Communication: While applying the learning
scenario, they share their thoughts, designs, and research results. They
use and develop their expression and communication skills while
introducing their materials.
4-Curiosity, questioning:
Students strengthen the aspects of curiosity, critical thinking, asking
questions, observing and evaluating.
|
Evaluation |
These learning scenarios and
activities saw that students could produce solutions to even a global
problem with their strengths.
They realized that waste is
recycled with different disciplines.
They discovered that
they could be socially responsible individuals in
society.
They learned by experiencing and observing that
project-based learning develops many aspects.
|
Assessment
|
Ask students to define the term biodegradable.
Ask students to explain what a dump is.
Ask students to explain what a compost pile is.
Ask students to describe what happens to their garbage after it is
thrown away.
Ask students to identify what types of materials are biodegradable,
and what types are not.
Bring in a number of new items of trash. Ask students to identify each
as biodegradable or not biodegradable. This may be done individually
or as a class.

Quick Quiz
|
Write down what 3RC stands for. (Answer: Reduce, reuse, recycle,
compost.)
Describe one way you can be involved in 3RC. (Accept all reasonable
answers.)
Describe how an engineer might be involved in one of the 3RC steps.
