1.05 Earth's Spheres C2

1.05 Earth's Spheres C2

This image is a model of a negative feedback loop.

Why is this considered a negative feedback loop?

Using the image above to help you, what is one benefit of wildfires?

Predict: How could higher temperatures lead to more wildfires?

Extend your thinking: What can humans do to reduce the impact of wildfire?

Scientific models change based on new information and technology.

Before watching the video below to learn more about how scientists determined the age of the Earth, make a prediction: How old is the Earth?

Bonus Science!

What has been your experience with wildfires? Have you or your loved ones ever been affected by wildfires?

Categorize aspects of wildfires into the appropriate sphere.

Identify the 2 spheres interacting in the following examples. Make sure to focus on the items in bold.

Ash may be carried by winds many miles from the fire and then dropped into streams.

Burned plant debris that did not blow away becomes the new soil that can provide some nutrients for new plants

Rainfall over burned land carries ash, soot, and dirt into streams and rivers, changing the turbidity, temperature, and pH.

Smoke and noxious fumes can coat the lungs of animals and people, affecting their ability to breathe.

Why is this considered a negative feedback loop?

Using the image above to help you, what is one benefit of wildfires?

Predict: How could higher temperatures lead to more wildfires?

Consider the following feedback loop:

Which type of feedback loop does this represent?

Justify your answer: Why did you select the type of feedback loop for the previous question? Select 2.

Extend your thinking: What can humans do to reduce the impact of wildfire?

Scientific models change based on new information and technology.

Before watching the video below to learn more about how scientists determined the age of the Earth, make a prediction: How old is the Earth?

Self Assessment: Learning Target #1: Identify Earth's spheres and describe how they interact

Self-Assessment: Learning Target #2: Define negative and positive feedback loops and explain how they are different

Self-Assessment: Learning Target #3: Describe the use of models in science and how they can change

Bonus Science!

When half of the parent atoms have become daughter atoms, that's called the half life of that element.
