Clean and Affordable Energy! - Grades 5-8 (30 minutes)

Related to: SDG 7, SDG 9, SDG 11, SDG 12, SDG 13

Intro: Renewable energy sources combat climate change. The future of humanity and the planet depends on how we generate electricity: it is important to have a reliable, sustainable and decarbonized energy system. In energy generation processes, renewables do not release greenhouse gases, making them the cleanest, most viable solution for preventing environmental degradation. They are a far better alternative than fossil fuels, helping to conserve the finite natural resources of the earth that produce neither greenhouse gases nor polluting emissions.

Activity:

1) Watch this National Geographic video that provides a general overview of different types of renewable energy sources. For further information, visit the following URLS:

https://www.nrdc.org/stories/renewable-energy-clean-facts

https://www.igs.com/energy-resource-center/energy-101/types-of-renewable-energy

2) Look around your home for 5-10 minutes. Take note and observe - What kind of sources of energy are you using? Think about what sort of environmental impact this has. Is it good or bad?

3) Taking into account what you have just learned, draw your ideal visual illustration of what types of energy you would want to use in your household (this could be hand drawn on paper/ designed on google drawing).

Takeaways:

Ask your students what they have learnt about:

  • The detrimental effects fossil fuels has on the environment

  • Alternative energy sources aside from fossil fuels

  • The overall importance of renewable energy sources

oil spill simulation - 25 minutes (Grades 5-8)

Grade Levels: All

Related SDGs: Life below water

Intro: Oil spills are an extreme danger to earth's waters, ecosystems, sea animals, and corals. In 2020, we approximately lost 1000 tonnes of oil to the environment from tanker spills. This activity simulates what happens in oil spills to let students observe the effects of these spills and allows for discussion on causes, effects, and ways to help.

Activity:

  1. Fill a container with water dyed blue like the ocean

  2. Pour oil on top (can be dyed black)

  3. Allow the students to write observations on what is happening

  4. Allow discussion on the possible causes of oil spills

  5. Explain how oil spills affect bodies of water, animals, plants, and ourselves

  6. Provide pictures of real-life situations to showcase the degree and size

  7. Provide materials such as sponges, spoons, cotton balls, feathers or other materials students suggest in order to find ways to clean up

Take-Aways:

  • Creative thinking and problem solving

  • Connections to the real world

  • Learning causes and effects

  • Figuring out solutions

Water filtration- 60 minutes (Grades 6-7)

Grade levels: 6-7

Related SDGs: Clean Water and Sanitation, Life Below Water

Intro: Access to clean water are limited and restricted for some parts of the world, causing many individuals to live with polluted water that can not be used for drinking, cooking and many other uses. In order to solve this issue, civil, environmental and mechanical engineers have been contributing in developing various technologies and systems in which can purify polluted water. This activity will allow students to understand the process of water filtration and showcase it using the problem-solving and engineering concepts/skills learnt in class.

Activity:

  • Research on water treatment processes (aeration, coagulation, sedimentation, filtration, and disinfection) and different types of filtrations used.

  • Follow the instruction on this article for creating a water filter using plastic bottle.

  • Create a CER on the results of the experiment, addressing which way (order of material used in the experiment) of filtration works the best.

Takeaways:

  • Understand how filtration and the water treatment process works

  • Create creative design methods (problem solving)

Terrarium- semesterly ongoing project (Grade 8)

Grade level: 8

Related SDGs: Climate action, Responsible Consumption and Production

Intro: We only have one earth. Education is a critical component in the increasingly urgent planetary battle against climate change. Climate change is detrimental to mankind as changes in weather and climate patterns can put lives at risk. Through this project, students are able to have a deeper understanding about climate change, sustainable farming and how the natural environment is self-sustaining. The model is able to represent first-hand the interconnectedness of our environment, and how just one imbalance in one organism can impact the ecosystem hence to an extent, creating undesirable conditions.

Activity:

  • Research on water treatment processes (aeration, coagulation, sedimentation, filtration, and disinfection) and different types of filtrations used.

  • Follow the instructions on this article for setting up the terrarium.

  • Sketch a model on how interconnectedness is seen in the terrarium.

  • Have individual investigations (topics can vary such as 'how does sunlight or the lack of it impact the terrarium?').

Takeaways:

  • Understand the impact of imbalance of one organism to the whole ecosystem.

  • Developing 'Science and Engineering Practices' Skills.
