Before a scientific theory is accepted and supported, it has

been tested many times by different scientists.

How should a scientific reviewing committee should confirm an experimenter’s results

large sample size w a lrg group of participants &many trials

What can you conclude based on the graph?

Number of push ups decreased after Tuesday

Why does the chocolate candy melt in the s'more?

Heat from marshmallow is transferred to bar to make it melt

Precipitation will increase in areas where there is

higher temperatures and more evaporation.

Why are coastal areas cooler during the day than inland areas?

A cool breeze blows from the sea during the day.

The coastal area of MS lie along the Gulf of Mexico. How does this affect weather of the region

prone to hurricanes that develop over the Gulf of Mexico.

Why might a scientist repeat an experiment if she didn't make a mistake in the first one?

To ensure that the results are consistent and repeatable.

Identify the variable(s) that a scientist needs to be aware of when replicating an experiment.

control, dependent, and independent

Based on the graph, what was the dependent variable in the experiment?

Average number of birds observed

All BUT ONE statement could describe a scientific theory. That is:

Accounts of how nature will behave under certain conditions.

When an experiment is repeated & new results are different from the original what is inferred?

Additional test/trials are needed.

5
What can you conclude based on the graph?
The number of push ups reached a plateau on Friday
The number of pushed increased steadily with each day.
Number of push ups decreased after Tuesday
Number of push ups increased the most between Mon and Tues
6
Why does the chocolate candy melt in the s'more?
Heat from marshmallow is transferred to bar to make it melt
It's so hot outside that it melts the candy bar.
The pressure applied by pushing makes the candy bar melt.
Candy bar gets cooler b/c the marshmallow absorbs the heat
7

translocation
conduction
convection
radiation
8
Developmentof science is usually a _ process, building on older _ in order to advance new ideas
laboratory; institutions
hasty; developments
gradual; knowledge
scattershot; ideas
9
Precipitation will increase in areas where there is
lower temperatures and more evaporation.
lower temperatures and less evaporation.
less transpiration and less run-off.
higher temperatures and more evaporation.
10
Why are coastal areas cooler during the day than inland areas?
Coastal areas experience storms every other day.
The sea absorbs the heat of the air over coastal areas.
A cool breeze blows from the sea during the day.
It rains during the day in coastal areas.
11
The coastal area of MS lie along the Gulf of Mexico. How does this affect weather of the region
prone to hurricanes that develop over the Gulf of Mexico.
Proximity results in low rainfall in the coastal regions.
The MS River empties into the Gulf, making the weather humid
Gulf of Mexico makes the weather cold throughout the year.
12
Large, rotating low-pressure storms that get their energy from warm tropical oceans are called
thunderstorms.
tornadoes.
tropical tsunamis.
tropical cyclones.
13

14
Sam wants to test the affects of different types of music on plant growth. Independent variable
Different types of music
Amount of sunlight
Plant Growth
There is none
15
Why might a scientist repeat an experiment if she didn't make a mistake in the first one?
To ensure that the results are consistent and repeatable.
To make more money.
To make sure to obtain expected results to match hypothesis.
To see if any portion can be skipped & get the same results
16
Groundwater moves from the ground through plants & back to atmosphere through the process of
transpiration.
run-off.
precipitation.
condensation.
17

20
All BUT ONE statement could describe a scientific theory. That is:
Scientifictheories are frequently overturned by new evidence
Newly discovered evidence may disprove a theory.
Evidence changes part of a theory, while big picture intact
Accounts of how nature will behave under certain conditions.
21
Scientific laws are different from society's laws because they
can be explained by man.
can be changed by man.
occur without man's approval.
can be ignored by man.
22
When an experiment is repeated & new results are different from the original what is inferred?
Additional test/trials are needed.
The hypothesis is incorrect and must be modified.
The 1st must be wrong b/c you know the 2nd results are right
Both results are wrong due to the discrepancy.
