Scientific Method

What is the concept of thrust in rocket propulsion?

• The force that keeps a rocket stable
• The force that slows down a rocket
• The force that pulls a rocket down towards Earth
• The force that propels a rocket forward

What are factors that can affect the flight of a rocket?

• Weight of the rocket
• Length and width of the rocket
• Size, shape, and location of the fins
• All of the above

What is the purpose of fins on a rocket?

• To stabilize the rocket
• To generate lift
• To reduce air resistance
• To increase thrust

What is air resistance in relation to rocket flight?

• The force that slows down a rocket
• The force that propels a rocket forward
• The force that keeps a rocket stable
• The force that pulls a rocket down towards Earth

What materials are needed for a rocket experiment?

• Straw and air
• Fins and weight
• Length and width
• Paper and tape

What are the steps of the scientific method?

• Observation, hypothesis, experiment, conclusion
• Hypothesis, observation, experiment, conclusion
• Experiment, observation, hypothesis, conclusion
• Conclusion, observation, hypothesis, experiment

What is the purpose of background research in the scientific method?

• To provide stability during flight
• To increase the speed of the rocket
• To control the direction of the rocket
• To gather information about the topic

What are the components of a hypothesis in an experiment?

• Prediction and explanation
• Control and experimental groups
• Materials and procedure
• Independent and dependent variables
