Preparing for Science Review

Ultimately, all scientific knowledge comes from:

• both experimentation and observation

• observation

• experimentation

• textbooks

A hypothesis must be

• observed

• experimental

• testable

• formed in a laboratory

In order for an experiment to be valid scientifically it must be...

• have quantitative measurements

• repeated many times

• be done in a controlled lab

• have qualitative measurements

Observations are made using

• uranium

• technology

• specific science tools

• our senses

Theories are used to ..........

• propose how the natural world works

• prove hypotheses

• explain large bodies of data

• determine truth from lies

Measurements of the heights of various plants in an experiment are called:

• inferences

• theories

• quantitative data

• technology

If you smell a awful smell when you open a jug of milk you are making an ...........

• quantitative measurement

• observation

• theory

• inference

If you see a grown man curled up in the corner crying almost every Sunday during football season you can infer he....

• is a New York Jets fan

• is afraid of spyders

• ate a large burrito

• hit his foot off the door

Proper experimental setup requires a control group for what purpose?

• to increase the chances that your data will support the hypothesis

• to have something to compare the results with from the experimental group

• to make sure other scientists can duplicate the experiment

• confuse people

We can use a pan balance to detemine

• mass

• temperature

• volume of a liquid

• inferences
