Humans have modified organisms for millennia through selective breeding and other techniques. But only in the past few decades have people gained the ability to directly alter organisms’ DNA to create Genetically Modified Organisms (GMOs). GMOs can help advance fields such as medicine and agriculture. In this activity, students will learn more about GMOs and their uses before creating an awareness campaign to address GMO misconceptions.
Students will discuss a disastrous event that led to erosion and use the event to contextualize the impact of erosion on humans and the ways humans increase and decrease erosion. Learning Outcomes: Determining examples of erosion and its positive and negative impacts on humans and analyzing an example of a human-induced ecosystem disruption and understanding how it caused erosion in the ecosystem over time.
Students will answer questions about the online Science News article “The Deepwater Horizon oil spill ruined long-term shore stability,” which explains how damage to plants and soils is causing coastal marshes to retreat in parts of Louisiana. A version of the article, “Shores still reeling from 2010 oil spill,” appears in the March 25, 2023 issue of Science News.
The emissions of greenhouse gases through human activities are changing the world and making it warmer. But there are technologies and strategies that can reduce these emissions and slow climate change. In this activity, students will research methods of reducing carbon dioxide production and removing carbon from the atmosphere and present on their findings.
Students will review, discuss and diagram atmospheric greenhouse gases and their impact on Earth. Then students will analyze a graph to begin thinking about what it will take to achieve net-zero emissions. Learning Outcomes: Reviewing greenhouses gases and their impact on Earth, diagramming human impact, understanding the idea of net-zero emissions.
The world population has reached 8 billion people, according to the United Nations. In this guide, students will learn about how the human population has grown over time and how it is projected to grow in the future, then analyze a graph of world population data. In a quick activity, students will think about how a growing human population might impact various industries and how changes at the national or international level might help those industries support a larger population.
In this quick activity, students will brainstorm the effects of population growth on industries such as agriculture and medicine, then will work collaboratively to come up with changes at the national or international level that will help those industries support the growing population.
Students will answer questions about the Science News article “The world population has now reached 8 billion,” which explores trends in human population growth. A version of the article, “Human population hits a milestone,” appears in the December 17, 2022 & December 31, 2022 issue of Science News.
Students will answer questions about the online Science News article “News stories have caught spiders in a web of misinformation,” which describes new research looking at how spiders are portrayed by the media. A version of the article, “News stories give spiders a bum rap” appears in the September 24, 2022 issue of Science News.
