View Bozeman science video Systems and System Models

What systems can you see in the materials in your home? For example:

• In your home you have created systems of using and reusing materials, recycling materials, and throwing away materials. What would be the impact on you and your family, if you changed one of these systems? For example, what would the impact be if you were asked to increase what your family recycles and decrease what they throw away?

• What is the system for deciding what your family recycles?

• What Is the system for deciding what you throw away?

• How are your systems in your home different or the same as systems in a friends or relative’s home?

• In the news, we have heard of some systems being impacted by the COVID19 virus. For example, it is harder to get some materials into our homes that were easy before - like toilet paper, yeast, and rice. Has your family been impacted by the change in supply systems due to the virus? If so, what is harder for your family to get now, that was easy before?
