- Q1
Why do scientists use models?
They are exact representations of reality.
They only exist in computer simulations.
They are always simple and easy to understand.
They can be used to test ideas and make predictions.
45s - Q2
The following are are types of Models except
Commercial Model
Mathematical Model
Conceptual Model
Physical Model
30s - Q3
What can be a limitation of scientific model?
They cannot perfectly capture all the complexities of a system.
They are never updated or improved.
They are only used in physics, not other sciences.
They are all based on real-world data.
30s - Q4
Models can be used to test ideas by simulating specific parts of a system, making it easier for scientists to understand how certain factors affect each other.

What resembles the Plum Pudding Model of the atom?
A complex mathematical equation describing electron behavior.
A positively charged sphere with negatively charges scattered throughout.
A tiny, solid ball with negative charges stuck on the outside.
A miniature solar system with planets orbiting a central nucleus.
30s - Q10
Why is the Plum Pudding Model helpful for scientists?
It shows how atoms are indivisible particles.
It shows the nucleus is the most massive part of the atom.
It shows electrons have specific energy levels.
It shows how atoms are mostly empty space.

What is the best definition of matter?
Anything that can be seen.
Anything that is hot.
Anything that is alive.
Anything that has mass and takes up space.
30s - Q13
Which state of matter has particles that are widely spread out and move freely, taking both the shape and volume of their container?
liquid
gas
plasma
solid
30s - Q14
What can you say about the particles of liquid in contrast with a solid?
More freedom to move and more space between them.
The same amount of movement and spacing.
Less movement and are more tightly packed.
A predictable pattern of movement.
45s - Q15
What happens to the particles of a material being heated?
Gains more definite shape and compactness
Nothing happens because heat is not absorbed
Moves farther away from each other
Slightly compacted but can move
