• Mass cannot be created or destroyed

• The mass of the products must equal the mass of the remains

• Mass can change

• Mass remains the same

• increasing Atomic Mass

In order for a fish to see a bug just above the surface of the water, light travels from the insect through the air and crosses into the water until it reaches the fishes' eye.  Which statement is true regarding the light wave as it travels?

• It will bend as it hits the water because it slows down

• it will bend as it hits the water because the water particles move slower than air

• it will travel straight from the bug to the fishes' eye because that is the most direct path

• it will travel straight from the bug to the fishes' eye because it will continue to travel at the speed of light

DOK Level 3: Strategic Thinking

Which of the following best defines science?

DOK Level 1: Recall

What is the role of evidence in modifying scientific theories?

• Evidence is rarely considered when modifying theories.

• Evidence can refute or support theories, leading to modifications.

• Theories are modified first, then evidence is found to support the changes.

• Evidence is only used to confirm existing theories, not modify them.
