Samuel conducts an experiment. He makes many observations and measurements and records each very carefully. At the conclusion of the experiment he discovers that the data he collected do not support his hypothesis. What should he do?
Report his observations and conclusions honestly, clearly stating that the data do not support the hypothesis.
Change his hypothesis to one that is supported by the data.
Change the data so that they support his hypothesis.
Throw all of his data and observations away and repeat the experiment
What is a hypothesis
An idea in science
A question and or prediction
An idea backed by tested factual evidence
Data and facts from experimentation
An experiment

Why is it important to have only one independent variable and to control the other variables when performing science experiments?
So you can tell which factor is causing the change in the experiment.
It does not matter, you can have as many independent variables as you want.
What is the independent variable?
The result or outcome that you measure in the experiment.
The variable that you change in the experiment
The variables that you control for in the experiment
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil and sunlight. In this investigation, what are the controlled variables?
Two control variables would be you would have to ensure that the plants have the same amount of solid and that they receive the same amount of sunlight
Water, apple juice, milk
Plant growth
The fake pill or medicine taken by members of a control group is a
placebo.

double-blind experiment.
variable.
The _______ group is the group that does not receive the experimental treatment.
Independent
Dependent
Control
Why do scientists write down every detail of an experiment?
Because they are picky
so other scientist can repeat their experiment
They like to take notes
The scientific test to try out a theory or see the effect of something

What part of the experiment is the data
If standing up requires more effort than sitting down then a person's pulse will be high standing than stilling
Heart rate after 1 min standing- 62bpm, after 2 min - 72 bpm after 3 min - 87 bpm
I wonder why my heart ate increases after I am standing?

Safety Apron
Name this tool and its purpose.
Graduated Cylinder; measures volume
Beaker; measures volume
Balance; measures mass
Meter Stick; measures length
What is a constant/control in an experiment?
Things that do not change in a experiment. It's the variable that stays the same. You can have many variables stay the same.
It's the variables that the scientist changes in the experiment
It's the variables that are being measured in an experiment
The name of the information that you get from your experiment (you organize it into charts and graphs).

Which of the following best describes the interaction of science and society?
Science and society do not interact.
Society can drive scientific research by providing support and funding opportunities for projects that are considered important by decision makers. Science can affect society by providing new technologies and advancements to meet the needs of society.
Science impacts society by providing solutions to society’s needs, but society has no impact on science.
Society impacts science by providing support and funding for important projects, but science does not impact society.
Scientists are always getting new data that they must fit into what they already know to make sense of the world
true
false
What happens when scientists find new evidence that does NOT support something they are studying?
They must use creativity to convince other scientists that the new evidence is wrong.
They must use creativity to change or adjust their hypotheses to fit the new evidence.
They must use creativity to find ways to make the new evidence fit their original explanations.
They must use creativity to ignore new evidence that contradicts their original explanations.
The picture shows Pluto, which was once classified as a planet in our solar system. In 2006, a group of astronomers decided that it was not a planet because of its size and location in space, and classified it as a dwarf planet instead. What does the reclassification of Pluto show about scientific knowledge?
that scientific knowledge is open to change when new interpretations are encountered
that new advancements in technology will always alter current scientific knowledge
that current scientific knowledge should be challenged and updated annually
that scientific knowledge can always be altered by individual groups of scientists
What two words should be in your hypothesis?
I think
If ...then...
It will
No idea
Which hypothesis is correctly written?
