What is the first stage in the design cycle?

Investigate / Research
Devise / Design
Produce / Creation
Testing and Evaluation

Correct Answer

A. Investigate / Research

Explanation

The first stage in the design cycle is to investigate and research. This involves gathering information, conducting surveys, and studying existing designs or solutions to understand the problem or need that the design is intended to address. Through investigation and research, designers can identify constraints, user requirements, and potential opportunities for innovation. This stage is crucial as it lays the foundation for the subsequent stages of the design process, such as devising a design solution, producing and creating the design, and testing and evaluating its effectiveness.

A mind map is a graphical method of showing your thinking and the way it links to one idea?

True
False

Correct Answer

A. True

Explanation

A mind map is indeed a graphical method of representing thoughts and ideas, illustrating the connections between various concepts. It is a visual tool that helps organize information and stimulate creative thinking. By using keywords, colors, and branches, a mind map visually displays the relationships and associations between different ideas, allowing for a better understanding and exploration of the subject matter. Therefore, the statement "A mind map is a graphical method of showing your thinking and the way it links to one idea" is accurate.

You only designed one idea as this was the best?

True
False

Correct Answer

A. False

Explanation

The statement suggests that the person only designed one idea because it was the best. However, the correct answer is False, indicating that this statement is not true. This implies that the person did not design only one idea, or that the reason for designing only one idea was not because it was the best.

The amount of water in the bottle changes how high the rocket goes?

True
False

Correct Answer

A. True

Explanation

The amount of water in the bottle affects the rocket's performance because it determines the mass of the rocket. When water is expelled as gas through the nozzle, it creates a reaction force that propels the rocket upwards. The more water there is, the greater the mass and therefore the greater the force generated. This results in a higher launch height for the rocket. Therefore, the statement "The amount of water in the bottle changes how high the rocket goes" is true.

Thrust can be thought of as a force which stops the rocket moving upwards?

True
False

Correct Answer

A. False

Explanation

Thrust is actually the force that propels the rocket upwards. It is the force generated by the engines of the rocket that pushes it forward and allows it to overcome the force of gravity, enabling it to move upwards. Therefore, the statement that thrust stops the rocket from moving upwards is incorrect.

Eye glasses are used to stop you working hard?

True
False

Correct Answer

A. False

Explanation

Eye glasses are not used to stop you from working hard. In fact, eye glasses are used to correct vision problems and improve clarity of vision. They help individuals with poor eyesight to see clearly and comfortably, allowing them to work more efficiently and effectively. Therefore, the statement that eye glasses are used to stop you from working hard is false.

What describes the minimum safety equipment in the workshop?

Eye glasses, ear muffs,
Eye glasses, ear muffs, Apron,
Eye glasses, Apron, Closed in shoes
Eye glasses, ear muffs, Apron, Closed in shoes,

Correct Answer

A. Eye glasses, Apron, Closed in shoes

Explanation

This answer describes the minimum safety equipment in the workshop. Eye glasses protect the eyes from any potential hazards or flying debris. An apron helps protect clothing from spills, chemicals, or other potential hazards. Closed-in shoes provide protection for the feet from heavy objects, chemicals, or other potential hazards. Ear muffs are not mentioned in the answer, so they are not considered part of the minimum safety equipment.

An evaluation is done after testing your Rocket to help improve the design next time?

True
False

Correct Answer

A. True

Explanation

Evaluating the performance of the rocket after testing is a crucial step in the design process. By analyzing the results and identifying areas for improvement, engineers can make necessary adjustments to enhance the design in future iterations. This iterative approach allows for continuous improvement and refinement of the rocket's design, ultimately leading to better performance and efficiency. Therefore, it is true that evaluation is done after testing to help improve the design next time.
