putting all of your observations together is known as what?
data
bonus question:

what are the three components in fertilizer that helps plants grow?
phosphorous, potassium and nitrogen
to design your experiment, you must have what?
an independent variable, your dependent variable and y our control group
It is the act of noticing and describing the things that happens in a very careful way
observation
you have two plants, one is receiving sunlight, and the other is not, you want to test how well do the plants grow. what is your dependent variable?
the growth of the plants
look at the following hypothesis: If I add fertilizer to the plant then, the plant will grow more. would be the independent variable?
the fertilizer
in your results, you state things such as " the measurement of the plant was 15 cm, the soil weighed 20 grams" this type of information is known as
Quantitative data
What is the goal of science?
The goal is to provide explanations for the things that happens in the world
this is an explanation using the words "if and then" that will guide the expectations of the experiment
a hypothesis
Name the three types of variables
Independent variable, Dependent Variable, and control group
You bought two kinds of fertilizers; you know that fertilizers helps plants grow because they contain 3 elements (Nitrogen, Phosphorous and Potassium). what can a possible hypothesis be?
If the fertilizer has more nitrogen, potassium and phosphorous, then it help the plant grow the most.

the plant that's not receiving sunlight.
summarizing your data and observations is known as?
a conclusion
data that describes something (such as color, smells and so forth) falls under what category?
Qualitative Data
control group
which variable depends on the independent variable?
the dependent variable
what is the variable that does not change because of other factors?
independent variable
what are the steps to the scientific method ?
asking a question, research, form your hypothesis , experiment, observe, analyze the data and come to a conclusion
these types of collected data, numbers and calculations, falls under what category?
Quantitative data
