These are my results:

Tuesday-Planned on science board
Wednesday-Typed up Aim and Hypothesis and made them fancy on Word
Thursday-Typed up Method and Apparatus on Word
Friday-Thought about how effective my science fair board will be
Staurday-Started testing
Sunday-Put results in graph
Monday-Posted everything on blog; Typed up variables and made them fancy on Word

I think I will put all my stuff on the science fair on yellow border because it stands out from my blue background. I will also put orange shadows on it because it looks good and it still stands out

Tuesday: Researched on hypothesis
Wednesday: Worked on green sheets
Thursday: Wrote down Apparatus and Method
Friday: Finished green sheets for homework
Saturday: Went to look for equipment needed (found out I didn't need any because I changed my Method), Changed Method
Sunday: Wrote down Apparatus and new Method
Monday: Inproved/Proof-Read Apparatus and Method, Published everything on blog
Method:

1.Nail nails to board slightly more to one side, leave fair amount of space inbetween

2.Attach rubber bands to nails according to amount of space inbetween

3.Put books under side with nails until the board is tilted at a 30 degree angle, make sure on flat surface and plenty of space infront of nailed side

4.Put marble infront of rubber band and pull back, mark where pulled back to lets marble roll down with rubber band when pulled back

5.Let go of rubber band, measure and record the distance from the board

6.Put marble infront of rubber band and pull back to mark, let marble roll down with rubber band when pulled back

7.Let go, measure and record distance and repeat 3 more times

8.Change angle to 45 degrees and repeat the method of flinging the marble 5 times

9.Change angle to 60 degrees and repeat the method of flinging the marble another 5 time

10.Compare results

Apparatus:
Protracter, Wooden Board, Ruler, 2 Nails,
Marker, Rubber Band(s), Books, Marble

I will know that I have developed a fair test by measuring all angles and distances accurately and firing with the same amount of strength.
