Cosmic Discovery -Lesson 4. System Analysis of our solar System

November6

Goal:

I understand how our solar system works as a system

APK

A system is:

-a set of things working together as parts of a mechanism or an interconnecting network;

OR

– a regularly interacting or interdependent (they rely on each other) group of items forming a complex unified whole

Try to come up with a list of 5 different “SYSTEMS” that follow this definition.

 

New info/ Application:

Today we will analyse our new information using SYSTEMS ANALYSIS- discuss steps from thinking skills sheet

First, write the definition for a system in your books.

 

Systems Analysis:  know how the parts of a whole impact the results:

  1. I name something as a system:

Our solar system as a system:

What are its parts? How are they interconnected? How do they affect each other?

 

  1. I tell how the parts work:

The parts are the objects/matter (from last lesson) & the energies.

What energies are there that connect or affect things in our solar system?

How do the things (matter) and the energies make the solar system ‘work’?

 

Show how “Universe Sandbox” (downloaded from universesandbox.com) works-explore to answer these questions.

 

  1. I change one part and tell how it works now

Change 1 item as a class:

-3 questions:

  • WHAT will we change?
  • IN WHAT WAY will we change it?
  • PREDICT the effects on the system

Try-discuss & record

  1. I do it again with a different part

What are changes that might happen to our solar system (no gravity/ less/ more gravity; remove a body; change the mass of a body)

In small groups:

-3 questions:

  • WHAT will we change?
  • IN WHAT WAY will we change it?
  • PREDICT the effects on the system

share with class and then run the experiment

(when running the experiment, first slow down the time, then make the change and speed up the time- you can also zoom in or out and toggle your perspective)

 

4. I explain what I know now or how to make it better

  • Are there any changes to our solar system that could make it BETTER?
  • Are there any ways we could make this happen?
  • How could we do it?

 

  • Are there any changes to our solar system that could make it WORSE?
  • Are there any ways we could make this happen?
  • How could we do it?

 

Goal reflection:

Further possible reflections-

Our solar solar system remains in balance because…..

Something unlikely that would change the balance would be … (& what might happen)

Something that is likely to change the balance in the future might be (& what might happen)
