What is a science Flashcards
1) how do you write a aim?
1) explain cause and effect
- what is cause?
- what is effect?
- always start it off with “to investigate” or “to determine”
what is a hypothesis?
when experimenter predicts the outcome of the study
for e.g chocolate will/will not increase dopamine
1) what is independent variable?
2) what is dependent variable?
1) independent= what you are changing
2) what you are measuring
why are there two versions of independent variable in experiment
to test if the iv has effect on dv
- for e.g your testing to see if fanta grows trees
- your going to have to use something else like water on your tree
- if you use both Fanta how are you going to know that Fanta is the one that grew the tree?
- if you use two different things you can see which one works
What is operationalise
how are we exactly going to measure the dv
for eg you want to measure memory
- that is hard bc memory is not saying how it going to be measured so you gonna have to change it to
-“numbers recalled after 10 mins”
- you have to be exact!
