Let’s discover how water connects us as water is always on the move -visible and invisible.
In this activity, students will learn how water connects us, is alive and always on the move. Sometimes water is on the surface in lakes and rivers where we can see it, but sometimes underground, and invisible but always in need of protection.
4. Have students share what they see. The water will move upwards through the paper towel, and the colours will mix in the empty cups, resulting in a rainbow of colours over time.
5. The water moves up the paper towels through a process called capillary action. The paper towel is made from fibres and the water travels through the gaps in the fibres, which pulls the water upward. In trees transpiration, which is water leaving the tree through its leaves, causes capillary action to take place drawing water up from the roots.
6. Water is always on the move. Maybe it's moving down a hill, going up a tree, or evaporating. It might collect underground (invisible) or on the surface (visible) and will be shared by animals, trees, people and for making clean, green electricity in B.C. We can use water for electricity because it's always on the move.
7. Remember to compost the paper cups and paper towels once the activity is complete.
These activities provide a link to the core competencies of the curriculum. The activities engage students in thinking about the interconnectedness of water and taking action on caring for water.
The activities also connect to a variety of grade-specific curricular competencies and content in a variety of subjects including Physical and Health Education, Social Studies and Science.
Often in Canada we only consider surface water sources, as this is clearly visible when we see the many lakes and rivers. However, in Canada, about 30% of the population rely on groundwater for domestic use. Groundwater needs protection as it can be contaminated by landfills, chemical or oil leaks, pesticides, fertilizers, or leaking septic tanks. For more information go to Water sources: groundwater.
Plants absorb water and nutrients from the soil as part of a process called transpiration. Water is emitted through the leaves of a plant (transpiration), causing a continuous upward flow or draw of water and nutrients through the roots by capillary action.
In B.C., we are powered by water. The electrical system stretches across each region of the province and the traditional territories of Indigenous Nations. We have 30 hydroelectric plants and a network of over 80,000 kilometres of power lines that transport electricity from our generating stations over mountain tops, through river valleys to homes and businesses in B.C. We have the cleanest generation in Western North America and amongst the lowest greenhouse gas emissions of any utility in North America.
We recognize that while water is core to our business, it also holds spiritual and cultural values to Indigenous Nations, and environmental importance to all communities in B.C. We’ll work together to protect the province’s water resources and honour these multiple uses and values as we move forward. Check out Environmental responsibility for ways BC Hydro is protecting and sharing the resource.
Young people can act at school, in their community and at home to protect and care for water. We can empower them with a deeper understanding of how essential water is to life and encourage them to share this message to respect, protect and honour water.
