Open
Closed
In our strawberry jars, the amount of matter cannot change because they are examples of ______ systems.
Open
Closed
Which of the following definitions best explains the Conservation of Matter?
The amount of matter decreases during physical and chemical changes.
The fact that the amount of matter stays the same during a physical or chemical change.
The amount of matter stays the same only during chemical changes.
The fact that new matter is created during physical and chemical changes.
Which of the following images does NOT accurately demonstrate the Conservation of Matter?
How does this image show the Conservation of Matter?
The matter in the apples is decreasing and disappearing into the soil.
The amount of matter in the apple is staying the same, but it is decomposing and going into the soil.
The soil is eating the apples and they are disappearing.
The apples are rotting and more soil matter is being created.
Which of the following answers does NOT show where the badger's flesh went when it decomposed.
The maggots consumed some flesh.
Some flesh went into the soil.
Some flesh disappeared.

Pupa
Which of the following are examples of mathematical models? Select more than one answer.
Shapes
Equations
Graphs
Symbols
Why are our decomposition bottles (dead columns) not examples of fair tests?
They have only one independent variable that we changed, so it is easy to see what is causing the decomposition.
They have no variables at all.
They have two independent variables, so it is easy to see what is causing the decomposition.
They have too many variables to determine what is causing the decomposition.
Which of the following factors can be accidentally added to an open system. Select all that apply.
Additional decomposers
Water
Air
Other organisms
Are the strawberries in the jars examples of open or closed systems?
Open
Closed
Are the decomposition bottles (dead columns) examples of open or closed systems?
Open
Closed
Which best describes what is happening to our dead plant parts in the decomposition bottles over time?
They are disappearing.
They are decomposing and breaking down into the soil.
They are going through a physical change.
They are staying the same and not breaking down.
Which of the following is NOT an example of a decomposer in our decomposition bottles (dead columns?)
Mold
Water
Bacteria
Worms
