Hello, super scientist! Did you know that the engineering design process is a cycle? That means it repeats over and over again. After they test their solutions, engineers always think about how to make them better. This brings them back to the brainstorming step. The design process is repeated until the solution is the best it can be.

Review the Engineering Design Process worksheet to understand the steps of the engineering design process. what does this mean.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
