What is ​NOT a benefit of using a scientific model?

•  A. It can be used to visualize a complex idea or concept. 
•  B. It can lose some accuracy in order to make it simple enough to use. 
•  C. It can represent something too small or large to manipulate. 
• D. It can be safer, quicker, and less expensive for the scientist to work with.

When discussing the theory of atoms, a model is the only option. Why is this true?   

• A. An atom is too small to be observed in detail with current technology.
•  B. Atoms are too expensive to collect for scientific use.
• C. An atom is too dangerous to handle in a lab setting.
•  D. An atomic model is easier to manipulate than a real atom.

Which of the following describes a limitation of the drawing but NOT ​a clay model?

• A. It cannot represent a living cell since the cytoplasm should be in constant motion.
•  B. It does not contain the correct number of nuclei.
• C. It does not represent the main parts of a cell. 
•  D. It cannot represent a living cell since a true cell is 3-dimensional.

Models of atoms have changed many times as scientists continued to study them.  After many science experiments throughout history, the model has been changed to what we know today.  Why was the model of the atom changed? 

• A. Scientists continue to discover new atomic elements but the model of the atom has not changed. 
• B. Scientists still cannot agree on a correct model for an atom. 
• C. The atomic model was modified as new evidence was encountered. 
• D. Scientific experiments cannot disprove the current model of the atom.

Spontaneous generation was an idea that living things appear from nonliving things.  This was disproved by Louis Pasteur's experiment using bacteria to demonstrate bacteria comes from existing bacteria.   What is this an example of?   

• A. A scientific theory changes as an organism evolves. 
• B. Scientific knowledge changes as new evidence is discovered by experiments.
•  C. Changes cannot be made because it is a scientific law. 
• D. Bacteria have been observed and modified many times.

If a scientist makes a new discovery, why must other scientists review and replicate the results before the discovery can be published? 

•  A. New discoveries can only be debated after they are published and confirmed
• B. Scientific knowledge must come from a great deal of debate and confirmation within the science community. 
•  C. Other scientists must like the new discovery before it can be published.
•  D. New discoveries must be accepted by all members of the scientific community first.

Which of these ​BEST describe how a scientific explanation becomes widely accepted? 

• A. A hypothesis is tested repeatedly and the results are confirmed and debated by the scientific community. 
•  B. It is debated by the scientific community. 
• C. A hypothesis is tested repeatedly and the results of the tests are debated.
• D. A hypothesis is tested repeatedly and the results are mostly supported by the scientific investigations.

Why is there debate to develop scientific knowledge within the scientific community?     

• A. Scientific debate is the only way to prove previous scientific findings were incorrect and should be ignored.
• B. Scientists debate because scientist believe their evidence is stronger than other scientist's evidence. 
• C. Scientists try to disprove each others work to reduce conflict within the scientific community.
• D. Scientific debate is a necessary part of scientific evidence and plays an important role in confirming scientific findings.
