THE STEPS
what is first step to the scientific method?
ask a question
what type of variable is changed or manipulated by the experimenter?
the independent variable
true or false: a hypothesis is a question you ask based on your gathered information
false
why is it important to observe?
so you can gather detailed information
do you need to have the correct measurements in a experiment?
yes you need to have the correct measurements in a experiment
what step number is collect the data?
number 4
what type of variable changes in response to the independent variable and is measured?
the dependent variable
what is a hypothesis?
an educated logical guess that can be tested
what is an observation?
a logical interpretation or guess based on your gathered information
what does PPE mean?
personal protective equipment
what is forming a conclusion?
the step of the method where scientists analyze their gathered information to determine if their hypothesis was supported
what type of variable changes in response to the independent variable and is measured?
controlled variables or constants
what makes a strong hypothesis?
a good hypothesis must be testable, measurable, and based on your existing knowledge and information, It must identify the variables you plan to change
what is a visual observation?
it is a type of observation involves using your eyes to watch a chemical reaction take place.
whats the most important protection for a science experiment?
safety goggles
during which step do scientists organize their measurements and facts into charts, tables, or graphs?
analyzing data
Identify the INDEPENDENT variable in this statement: If you increase the number of times you practice free-throws, your chances of making a basket increases.
the amount of practice free throws
for a hypothesis to be valuable it has to be --------?
testable
what do you use to observe?
your five senses ( sight, smell, taste, touch, and sound )
were would you list your equipment required on a lab report?
the material section
If the data does not support the hypothesis what should a scientist do next?
form a new hypothesis and start again
Identify the DEPENDENT variable in this statement: If soil temperature rises, the plants growth will increase.
plant growth / the height
what is a theory?
a broad explanation for a natural phenomenon that is already heavily supported by evidence.
whats the difference between experimenting and observing?
experimenting is testing different things and seeing if your hypothesis is correct. observing is using your five senses to find out what happened in the experiment
is it important to have proper equipment?
yes, very important
