Science 1
True or False
A hypothesis must always be correct
False
What is the observation?
The flashlight won’t turn on.
What is the variable that you measure or observe?
Dependent variable
What is the observation?
The plant’s leaves are turning yellow.
What is an educated guess also known as
Hypothesis
What is the variable that you purposely change
Independent variable
What is a possible question?
Why isn’t the flashlight turning on?
What variable stays the same to keep the test fair?
Controlled Variable
What is a possible question?
Why are the leaves turning yellow?
Define “experiment.”
A procedure used to test a hypothesis.
Define “hypothesis.”
An educated guess used to test the hypothesis
What is a possible hypothesis?
If the batteries are dead then that is why my flashlight wont turn on.
In an experiment testing how fertilizer affects plant growth, what is the independent variable?
The type or the amount of fertilizer
What is a possible hypothesis?
If the plant is not getting enough water then that is why the leaves are turning yellow.
In a plant experiment, if you change the amount of sunlight, what variable is the sunlight?
Independent Variable
Define “observation.”
Using the 5 senses to gather information.
What would be the experiment?
Replace the batteries and test the flashlight.
In the same experiment, what is the dependent variable?
The plant’s growth (height, number of leaves, etc.)
What could be an experiment to test this hypothesis?
Water the plant regularly and see if the leaves stop turning yellow.
Define “conclusion.”
A summary of what you learned; whether the hypothesis was supported or not.
Give an example of a controlled variable in an experiment testing how fertilizer affects plant growth.
Soil type, water amount, pot size, temperature
What would be the conclusion if the flashlight works after new batteries are put in?
The hypothesis was correct—the batteries were the problem.
Name all the 6 steps of the scientific method and define them
Observation- what we are observing using the 5 sense
Question- what you want to know
Hypothesis- an educated guess
Experiment- testing your hypothesis
Data-information you got from your experiment
Conclusion-what happened and what you learnt
If watering doesn’t work, what should the student do next?
Form a new hypothesis and design another experiment (maybe check sunlight or soil).
Name all 3 variables and define them
Independent- something you change
Dependent- something you observe or measure
Controlled- something that stays the same
