Answer:
Independent Variable: Grade Level
Dependent Variable: Growth in height
Hypothesis: Students in [Insert the grade level you believe will grow the quickest here] will experience the quickest growth in height.
Explanation:
Independent variables are the factors in which you manipulate to gain your results, in this case you would be changing the grade level you would observe to see the height.
Dependent variables are the factors that respond to changes in the independent variables. You don't control these events, you simply observe them. In this case, you merely observe the growth in height in accordance to the different grade levels you observe.
For the hypothesis, you would create your own hypothesis based on a guess you have. You create a hypothesis not based on the data, but on what you believe will be correct before doing the experiment. It doesn't have to be the correct answer, but just your thoughts.
Answer:
C E F G
Explanation:
1s2 2s2 2p2 is carbon element, group 4 so A is false, it is not a noble gas so B is false, P-block elements are from 13 to 18 so carbon is included so C is true, S-block elements are columns 1 and 2 and Helium so carbon not included so D false, it is in period 2 so E true, has 2 energy levels so F true, it is a representative element so G is true
