Nature of Science Test Review

Objects and conditions that are moving are easier to observe because our senses notice things that are changing rapidly. Which condition DOES NOT fit into a "moving" category?

• A campfire reducing wood to ash

• A fireworks display

• A rusting hull of a ship

Choose the item that can only be observed with a scientific instrument (not just your senses).

• Hypothesis

• Model

• # trials

 A variable that stands alone and isn’t changed by other variables you are trying to measure

• Model

• Observation

• Independent Variable

A testable idea or explanation that leads to scientific investigation

• Observation

• Hypothesis

• Theory

Organized procedure to study something under controlled conditions. Investigations which are often done in a laboratory

• Science

• Hypothesis

• Experiment

Systematic study of the natural events and conditions and it is the logical, structured way of thinking about the world; it is where we ask questions and gather information

• Graph

• Data

• Science

 What changes as a result of the independent variable manipulation in experiments. Response variable that responds to a change in another variable

• Data

• X-Axis

Process of obtaining information by using the senses

• Observation

remains unchanged or held constant to prevent its effects on the outcome
