Question

Rachel wants to develop a lamp that will work using a remote control. Which statement best describes the process she should use?

She should use scientific investigation because she will need to analyze the results.
She should use technological design because she will need to design an experiment.
She should use scientific investigation because she will need to communicate her findings.
She should use technological design because she will need to build a prototype.

Answer 1

The best statement that describes the process that she should take would be that she would need to use a technological design, because she would need to build a prototype. There is no need for scientific investigation as she is not trying to answer by experimenting and making observations of a particular question.

Answer 2

The correct answer is option (d)

In case Rachel wants to develop a lamp that will work using a remote control then she should first make a prototype so that she can perfectly make the lamp. The purpose of making a prototype is to understand the product. Prototype models use photos shows and trade shows so that the problems related to the model is known earlier. The defects that is present in prototype can be avoided in the main model and the feedback can be analysed to improve in the actual design.
