Esma and Hasan are putting the finishing touches on their model for a tiny chip-based energy source to

Question

power their lighting system. What phase of the engineering design process should they complete next?
answers:
build a prototype
test their work
confirm with research
get the product priced

Answer 1

In the engineering design process, after completing the initial design and before finalizing the product, the next step should typically be to "build a prototype." This allows them to create a tangible version of their energy source, which can then be tested and evaluated for functionality and performance. Therefore, the correct answer is:

build a prototype
