Science - Ch. 1 - Fill in the Blank

_____________ bioengineered technologies help organisms without changing them. Examples of this are hearing aids, eyeglasses, a set of crutches and prosthetic limbs. _______________ bioengineered products change the organism. Examples of these are cochlear implants, surgery to create more open airways for the lungs, and artificial hearts.

Assistive Adaptive

The ______________ is an example of a conceptual model.

Big Bang Theory

_______________ your results will allow other scientists to use your investigation for research or conduct an investigation of their own.

Communicating

The ______________ was formed so that all people and scientists around the world would have a simple, reliable and standard measurement system to use. All units in this system are based on the number 10.

International System of Units (SI)

__________ is the amount of matter that something is made of, while _________ is the amount of matter in a given volume. Mass can be measured directly in ____________, but density can only be calculated as follows: density=mass/volume.

Mass density kilograms

__________________ is 98.6 degrees Fahrenheit and 37 degrees Celsius.

Normal body temperature

___________________ are the ways in which scientists answer questions and solve problems.

Scientific methods

After you have your data, you must __________ them to determine if the results of your test support the hypothesis.

analyze

The length multiplied by the width of an object is the _______ of the object

area

Technology has intended _____________ and _________________ consequences.

benefits unintended

A _______________ compares the results from a control group with the results from one or more experimental groups. The control group and the experimental groups are the same except for one factor, called a __________.

controlled experiment variable

Pieces of information acquired through experimentation are known as ________. The data samples must be large enough to insure that the results of the experiment are due to the _________ and not due to the normal variation between samples.

data variable

Because _______________ must understand the communities of organisms and their nonliving environments, they are able to work in many fields such as wildlife management, agriculture, forestry, and conservation.

ecologists

The ______________ is very similar to the scientific process. Many of the steps are the same: Identify a need, Develop possible solutions, Make a prototype, test and evaluate, modify and retest the solution, and communicate the results. A _______ is a model used to test new technologies.

engineering design process prototype

If materials for your experiment are hard to find, don't give up! Do more research and try to find the results from someone else's ______________.

experiment

A _______________ specializes in the chemistry of rocks, minerals and soil and determines the economic value of these materials.

geochemist

Conclusions that you draw from your results will show you if your test supported your ______________.

hypothesis

Science can be used to answer questions that help us to save ___________, ____________ and the ___________.

lives resources environment

One of the most common careers that _____________ have is that of a weather forecaster.

meteorologists

A ________ uses something familiar to help you understand something that is not familiar. Three major kinds of scientific models are _______________, _________________ and ________________.

model physical mathematical conceptual

Noting that the sky is blue and that a cotton ball is soft, or taking measurements are all examples of an ________________.

observation

Scientists usually state ___________ in an if-then format.

A volcanologist, a geochemist and an ecologist are 3 jobs that use ___________.

science

Engineers use _________ and ___________ to create new technologies that serve human needs.

science mathematics

A ____________________ summarizes experimental results and observations. It describes what happens, but not why something happens. It tells you to expect the same thing to happen every time.

scientific law

A ___________________ is an explanation for many hypotheses and observations.

scientific theory

Observations are any use of the ________ to gather information.

senses

Engineers create and use ______________ to make tools for practical purposes and to determine the efficiency of existing tools. Efficient tools cost less money and save resources.

technology

After a hypothesis is formed, it must be __________ to determine if it is a reasonable answer to your question.

tested

To get the best measurements, you need the proper ______. Examples of these are: stopwatches, metersticks, balances, thermometers, spring scales and graduated cylinders.
