D. Practicing the Scientific MethodFor my experiment, In my first step I made a graph, in the second step I also identified variables, for the third step I developed a hypotheses, during the fourth and fifth step I designed a controlled experiment and finally for the sixth step, a partner and me predicted and discussed the possible results.

E. Experimental DataPart 1: I was given data to make a graph, below. I used a Google spreadsheet to create a graph and I saved my image file to upload here. My graph demonstrates an inverse relationship between the apple maturation time and the concentration of ethylene because it was observed that as time maturation time increases, the concentration of ethylene decreases. This is be due to the effects of ethylene which is known to be released by plants naturally which causes plants to grow faster.

F. VariablesPart 2: Potential environmental variables to consider:
1. Amount of water 2. Amount of wind 3. Amount of sunlight

H. Control Groups - Read more>
Part 4: It is important to have control variables because the variables show the difference in the group that does and doesn't get the amount of sunlight that's given.
Control Group: A group of trees receiving an ideal amount of light (i.e. greenhouse). Experimental Groups:

J. Expected Results
Part 6: I would expect to see that the group that got the direct sunlight (group C) would be the tallest because If its too dark the trees (group A) didn't grow at all, the trees that were in the sunlight (group B ) would grow in a different time, than the other groups. If my hypothesis that the sunlight will affect the growth of the trees is truth, then I will see the three groups growing at a different time.
Deeper Analyses Viewing Experiment
Playing shooter and driving VIDEO-GAMES improves top-down guidance in visual search.
Background: Playing action video games is known to improve visual spatial attention and related skills. Here, we showed that playing action video games also improves classic visual search, as well as the ability to locate targets in a dual search that mimics certain aspects of an action video game.
Hypothesis: I believe that playing shooter, driving video games and 3-D puzzle games improves top-down guidance in visual search because I have observed and seen that experienced video game players were faster than non-players. If my hypothesis is true, I will see that experienced video game players are faster and more accurate in a peripheral search and identification task while simultaneously performing a central search, than no experienced video game players |
Independent Variable: game action level
Dependent Variable: post game attention level Control Group: Experienced video game players.
Experimental Group: No experienced video game players. Experimental Procedure:
1. Put a team of experienced video game players (team 1) in a table with gaming consoles. Put another team with people that have no experience playing video games (team 2). 2. Put a first person shooter (FPS) video game, that non of the teams has ever played. Test the two teams with the same video game and the same level. After 2 hours of playing, give the two teams a rest of 1 hour and put a 3-D puzzle. 3. Watch the difference between the two teams. 5. Let team 1 rest and put team 2, 10 hours playing (5 hours First Person Shooter game, 5 hours 3-D Puzzle game) with short intervals. 6. See if team 2 improved or not their top-down guidance in visual search. 7. Record the results. |
Conclusion: Participants who played an action game (either an FPS or a driving game) achieved greater gains on all search tasks than did those who trained using the puzzle game. Feature searches were faster after playing an action videogame, suggesting that players developed a better target template to guide search in a top-down manner. The results of the dual search suggest that, in addition to enhancing the ability to divide attention, playing an action game improves the top-down guidance of attention to possible target locations. The results have practical implications for the development of training tools to improve perceptual and cognitive skills.
