Making a prediction about the outcome of an experiment is which step?
Hypothesis
200
a scientist who uses science for practical purposes
Who is an engineer?

300
a scientist who applies engineering to living things
Who is a bioengineer?

What is the difference between observation and hypothesis?
Observation is using the five sense to gain information and ask questions. Hypothesis is a potential answer/guess to those questions.

What is an unintended consequence of the cell phone?
interruptions, car accident while on the phone, etc.

Compare and contrast adaptive and assistive technology. Give examples.
Both types of technology help living organisms live better lives. However, adaptive technology changes the living organism while assistive technology does not. Examples of assistive: eyeglasses, hearing aids, etc. Examples of adaptive: cochlear implant, artificial heart, other artificial organs

What is the step in the scientific method where you usually make a graph?
analyze and interpret data
500
A person who predicts the weather.
Who is a meteorologist?
500
Contrast theory and law.
A theory is an explanation of why something happened the way it did. Theories are repeatedly tested and can be supported by test results. A law is a theory that has been tested and now explains how things work, but not why.

What instrument is used to measure volume?
a graduated cylinder

A group of environmental scientists suspects that acid precipitation is beginning to affect certain lakes in Tennessee. What tools and procedures could they use to test their hypothesis? A. Use research studies and research the harmful effects of acid precipitation in lakes. B. Collect acid precipitation in containers and experiment on water plants native to Tennessee. C. Use a field guide and count the number of water plant species found in a Tennessee lake. D. Use sterile containers and equipment, collect lake water samples, and test the pH of each sample.
