science quiz tmr!!!

what skill is a scientist using when she listens to the sounds the whales make

making observations

Not a rule when writing a hypothesis

it should restate the question

the process of obtaining information by the senses is called a/an

observation

a series of steps designed to help you solve problems and answer questions

scientific method

in a experiment the one variable that is changed is called the

independent variable

when you decide whether or not the data supports the original hypothesis you are

drawing conclusions

when a scientist shares her findings with other scientists she is

communicating results

in a experiment the factor that we measure is called the

dependent variable

in which step of the scientific method do we want to use graphs

analyze data

the final part; a summery of reasonable inferences is an

conclusion

the child’s temperature is 101 degrees

quantitative

an observation example is

leaves on the tree are green

the clock chimed twice

observation

a hypothesis is a - of the outcome of the experiment

prediction

how do you test a hypothesis

perform an experiment

the control is

stays the same and is what the test group is compared to

ultimately all scientific knowledge comes from

experimentation and observation

a hypothesis must be

testable

a good experiment is

repeatable

to be a valid experiment you should have

a control group, one changed variable, an experimental group

what is the independent variable in this graph

time

what is the dependent variable in this graph

temperature

these are conditions in a experiment that should stay the same for both control and experimental groups

constants

what type of graph would you use to compare data

bar

this type of graph is used to show data over time and used to look at the trends

line
