Human Activities
Urban growth that replaces natural habitats with buildings and roads.
What is urbanization?
The variety of living organisms in an area.
What is biodiversity?
Organisms that naturally live in an ecosystem.
What are native species?
Creating a plan to solve a problem.
What is designing?
Judging how well a solution works.
What is evaluating?
Structures built across rivers to control water flow and generate power.
What are dams?
When animals or plants lose their natural homes.
What is habitat loss?
Organisms that hunt others for food.
What are predators?
A rule or limit in a design (time, cost, materials).
What is a constraint?
Making changes to improve a design.
What is refining?
Species introduced to new areas that spread quickly and harm native organisms.
What are invasive species?
Polluted runoff entering rivers, lakes, or oceans.
What is water pollution?
Organisms that make their own food using sunlight.
What are producers?
Name one solution to reduce pollution.
What is recycling, cleaner energy, or waste treatment?
Why should solutions be tested?
What is to see if they work and find problems?
Name one human activity that can negatively affect ecosystems.
What is pollution/deforestation/overfishing/urbanization?
Name two impacts humans can have on ecosystems.
What are habitat loss and pollution?
Why is biodiversity important to humans?
What is food/medicine/ecosystem services/stability?
Propose one way to reduce the impact of urbanization.
What is building green spaces, wildlife corridors, or smart planning?
What kind of evidence helps improve environmental solutions?
What is data, observations, or research?
Explain how building a dam can change an ecosystem.
What is blocking fish migration/changing water flow/or flooding habitats?
Why does losing biodiversity make ecosystems weaker?
What is reduced stability, fewer resources, or less resilience to change?
Give one example of how losing one species can affect others.
What is food webs breaking down or population changes?
Design a solution to help stop invasive species (brief).
What is removal programs, education, or prevention methods?
Give one way you could improve a solution after testing it.
What is adjusting materials, changing methods, or adding protections?
