(19 cards)
scientific theory
a supported hypothesis proven multiple times and accepted by scientists
hypothesis
a guess of an expiriment often used with then and if
example: if you put gummybears in water then it will increase in size
independant varible
what is changed in the expiriment {what we change}
example: one has water, one doesnt
dependant varible
what changes during the expiriment, example the size of the gummy bear
controlled varible
what is kept the same, example the same gummy bear, the same glass etc
control
what we compare our results against, we compare our gummy bear with the gummy bear with water
ethic
conduct somethung being right or wrong.
example: is cloning animals good or bad
qualitive
CAN NOT be meassured using numbers
example: the colour of the sky
quantiitive
CAN be meassuered using numbers
example: your age,
number of goals in a football match
Science in the media
Sometimes the science articles on social media may be fake
scientific journal
scientists post there ideas and the results of there investigation/expiriment on here
primary source
Evidence from what you have personally tested
example: our gummybear expiriment as we tried it for ourselfs
Secondary source
Evidence from other scientists
example: why the sky is blue other scientists found this out.
Bias
favourism towards one side of a scientific debate
realibility
results are similar every time u test the expiriment
sustainability
resources available for future generations
changes we can make to help the enviroment example recycling or using loose fruits instead of fruit in plastic containers
accuracy
you get the exact result what you aimed for
precision
how close the meassurments are to one another
accuracy and precision together
if something is exactly the result you aimed for and its close together
