Change and rates of change can be quantified and modeled over very short or very long periods of time. In Activity 4, students make predictions, based on modeling, to explore changes to water tables and surface water. Teachers will need to set up a free account with High-Adventure science in order to print out student responses. This is mainly done in activity four, groundwater and surface water. And as our population continues to grow there’s just going to be more problems. Teachers could bring this out more by prompting students to explore where higher populations are and how much freshwater is accessible in that region. In the final activity, students use an interactive to analyze how water is cycled differently in urban versus rural areas. Significant progress has been made since 1990, with one-third of humans gaining access to improved water. An additional 4 billion inhabitants before the end of the century will drive up the number of people living in water … HS-ESS3-1 Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity. Data is automatically saved and answers can be accessed by the instructor. Logically, this would encourage the public to conserve more. An example of the far-reaching impacts from a human activity is how an increase in atmospheric carbon dioxide results in an increase in photosynthetic biomass on land and an increase in ocean acidification, with resulting impacts on sea organism health and marine populations. Students answer questions in boxes or by multiple choices in the various activities. The third activity has students using another interactive model to explore how water moves through rocks and determine where the best aquifers are located using data from the model. An example of the far-reaching impacts from a human activity is how an increase in atmospheric carbon dioxide results in an increase in photosynthetic biomass on land and an increase in ocean acidification, with resulting impacts on sea organism health and marine populations. Students look at how water is replenished in aquifers by the porosity and permeability of rocks. Focused effort over the past 15 years as a Millennium Development Goal made a world of difference for 2.6 billion people. The unit builds understanding through building understanding of the water cycle and the various ways the cycle can be impacted by both naturally occurring and human impacts. The Sustainable Development Goal over the next 15 years is to ensure liquid gold for the remaining 660 million. Students look at changes to groundwater and water tables as a result of human consumption of freshwater. While human impact and use, as well as the ways we have changed our use of water, is discussed, no strong correlation is made to location of water and human society. HS-ESS3-6 Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity. Icecaps contain double the fresh water of the world’s lakes and rivers, which all goes to waste when they break free and melt into the salty ocean. Students explore dams and their effects as well, showing how some changes cannot be reversed. In a series of five activities, students will explore the question, "Will there be enough freshwater?" This blog post was originally published here. This article is published in collaboration with SAP Community Network. In the video, she discusses that we live along coasts but source our water from the ground. Global Goal #6: Ensure availability and sustainable management of water and sanitation for all. Examples of Earth systems to be considered are the hydrosphere, atmosphere, cryosphere, geosphere, and/or biosphere. To learn more about the 17 Global Goals and how you can help make the world a better place, follow the 17 Weeks to Davos blog series. They explore how changes in local areas can have larger impacts.
