Where do you think the items came from originally?
Do you think the items look the same today as they did a month ago?
What happened to the matter in each item over the past month?
Do you think the items will be the same forever? Why or why not?
What do all of the items in the bag have in common?
Do you notice any relationships between the items in the bags? They all...
What evidence do you have that the items were all once part of a living thing?
Another name for "nature's waste" is "organic remains." These are all organisms that are no longer living, or parts of organisms that are discarded, excreted, or no longer needed. What other examples of organic remains can you think of?
What would happen to each item from your bag if it were left outside? What might it look like in 6 months? What would cause it to change?
What would eventually happen to the waste MATTER in each type of organic remain?
Why isn't the earth just piled up with all the matter from nature's waste?
Why could all of the items in the mystery bags be classified as nature's waste?
Do you think that all living things generate waste? What makes you think that?
I think they came from trees and plants because there leafs and sticks.
No, because they are less healthy and are not as as green and they are not getting food.
It decayed and died because it wasn't getting any nutrients.
No, because they are decaying and turning black and becoming soil.
They all are from trees and plants and they will all eventually become soil for other plants.
The grass and the plants both use photosynthesis to get nutrients. All the things will become soil.
They all have energy and when they brake down other plants get nutrients from them.
Sticks, Dog hair, and animal manure.
It might start looking like soil and it would look like this because it has no nutrients and it is dead or dying.
The waste matter would start to turn into soil and nutrients for the other plants.
It sort of is piled up with natures waste in soil ( because soil is plant waste) but other plants that are still alive take up and use some of the decayed plants energy.
It can all be classified as natures waste because it is all something that was part of nature but eventually it was not needed so nature got rid of it.
All living things generate waste because nothing can keep everything and still be healthy. If we did humans would be thousands of pounds.
