Observations
A hypothesis is...
What is an educated guess that answers the question?
What step of the scientific method is this: 1. Add sugar to the water 2. Taste water 3. Write down information
Experiment
What is a variable?
Anything that a scientist can choose to change or not change, anything that can be tested, controlled, or changed
What is an observation?
Something that you notice with your 5 senses
What step comes after your observations?
Background Research
Is this a testable scientific question: How does sunlight affect plant growth?
Yes
Why do we do experiments?
To test our hypothesis
Fill in the blanks:
The __________ variable depends on the __________ variable
Dependent, independent
What do you do in the conclusion?
Summarize and say if your hypothesis was supported
Is the following a good scientific question and why/why not:
Which brand of soap smells better?
No because it is opinion
What is the proper formatting for a hypothesis?
If _________, then __________.
What part of the scientific method is this:
Distance Ran by girls: 5 feet, 2 miles, 6 feet, 4 miles, 7 feet, 5 miles
Distance Ran by boys: 2.5 miles, 9 feet, 7 miles, 8 feet, 3 miles, 10 feet
Data analysis/collection
What is a control variable?
A variable that stays the same
If your hypothesis was: If I take away light, then the plant will grow and your results are that the plant did not grow without light, was your hypothesis supported by the results?
Yes
Which variable do we the experimenters measure?
Dependent variable
Is this a proper hypothesis: I think that the sun will grow taller without sunlight.
No
What is the difference between the experiment and the data analysis?
The experiment tests the hypothesis and its where you actually run the experiment and the data analysis is when you interpret the results of the experiment
What variable do you, the experimenter change?
Independent
What is the difference between the independent and the dependent variable?
Independent is what we change as the experimenter and the dependent is what we measure
A scientist wants to test the affect of sunlight on plant growth.
Type of soil, type of plant, amount of water, what room it is in, etc
Come up with a hypothesis that answers the following question:
How does fertilizer impact plant growth?
If I add fertilizer to the soil, then the plants will/won't grow more.

Identify the independent and dependent variable in the following experiment:
A scientist is testing to see how the levels of salt in water impact dolphin health.
Independent: levels of salt
Dependent: dolphin health
