How are people affecting your local environment? How is our planet changing? Join the “citizen science” movement, and you can help discover the answers.
Citizen science is a form of open collaboration in which members of the public participate in the scientific process to address real-world problems. Volunteers can work with scientists to identify research questions, collect and analyze data, interpret results, make new discoveries, develop technologies and applications, as well as solve complex problems.
Think about the weather and environment where you live. Have you ever been in a strong storm? Have you ever experienced flooding, a wildfire, or really hot days? These types of environmental hazards are happening more often because of climate change. Even though these events can be scary, there is so much you can do in your own community to make it better able to handle these challenges. When we work together to protect our communities from environmental hazards, we are building community resilience.
All biological organisms require certain nutrients to live. Plants require carbon, hydrogen, and oxygen from air and water, as well as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper, zinc, nickel, chloride, boron, and molybdenum from soil. Animals require a few others. Conversions and transformations of nutrients in the environment result from chemical reactions, biological activity, or both.
No matter where we are on Earth, we can observe changes in vegetation. Some changes are drastic, such as going from dormant to full growth during a temperate winter.
Vegetative growth is dependent on both surface temperature (which influences soil temperature) and precipitation (which influences soil moisture). Together these environmental variables help determine the beginning, duration, and end of the growing season; the latter marked by leaf senescence, when leaves of deciduous trees die and turn colors.
Archaeological remains include artifacts (portable) and features (non-portable) made and used by humans. Archaeologists use these objects to understand how ancient people lived. How well archaeological remains survive depends on the materials they were made of, the ways they were used, the manner in which they were discarded, and the environment in which they were deposited. Organic remains generally decay in a short time unless preserved in special conditions.
