6th Science ACA Semester Review

In an experiment measuring fuel efficiency, what is the independent variable?

• The type of fuel used.

• The distance traveled.

• The weight of the vehicle.

• The speed of the vehicle.

What is kinetic energy?

• Kinetic energy is the energy an object possesses due to its motion.

• Kinetic energy is the energy stored in an object at rest.

• Kinetic energy is the energy released during a chemical reaction.

• Kinetic energy is the energy associated with an object's position.

What is the definition of potential energy?

• Potential energy is the energy stored in an object due to its position or state.

• Potential energy is the energy of motion in an object.

• Potential energy is the energy released during a chemical reaction.

• Potential energy is the energy associated with the temperature of an object.

What is data in scientific research?

• Data is the information collected during an experiment, which can be analyzed to draw conclusions.

• Data is the hypothesis formed before conducting an experiment.

• Data is the conclusion drawn after analyzing the results of an experiment.

• Data is the materials used in an experiment.

What should you do if you do not understand a direction or part of a lab procedure?

• Proceed with caution and hope for the best.

• Ask a classmate for their interpretation.

• Ask the instructor before proceeding.

• Ignore it and continue with the experiment.

What is the scientific method?

• A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

• A random approach to solving problems without any structured methodology.

• A method used exclusively in laboratory settings for conducting experiments.

• A philosophical approach to understanding the universe without empirical evidence.

How does kinetic energy change as an object moves faster?

• Kinetic energy decreases as an object moves faster.

• Kinetic energy remains constant as an object moves faster.

• Kinetic energy increases as an object moves faster.

• Kinetic energy fluctuates as an object moves faster.

What is a control group?

• A group in an experiment that receives treatment to test its effects.

• A group in an experiment that does not receive treatment and is used as a benchmark to measure how the other tested subjects do.

• A group of subjects that are randomly selected for an experiment.

• A group that is used to manipulate variables in an experiment.

What is an experiment?

• A method to collect data without testing a hypothesis.

• A scientific procedure undertaken to test a hypothesis.

• A way to analyze existing data without conducting tests.

• A casual observation made during a scientific study.

What is the difference between independent and dependent variables?

• The independent variable is the one that is measured, while the dependent variable is the one that is changed or controlled in an experiment.

• The independent variable is the one that is changed or controlled in an experiment, while the dependent variable is the one that is measured.

• The independent variable is always a constant, while the dependent variable can vary.

• The independent variable is the one that is not affected by other variables, while the dependent variable is influenced by the independent variable.
