|Experiment Title:||Testing What Type of Bridge Will Hold Me Better|
|What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.:||The purpose of my experiment was to see which type of box bridge can hold me better.|
|What was your hypothesis?:||My hypothesis was the bridge with supports at each corner (Bridge 1) would hold my weight, the second bridge with the supports along the long sides (Bridge 2) would not hold my weight, the third one with supports on the short sides (Bridge 3) would hold my weight but would be weaker.My hypothesis for Bridge 1 was also that it would hold me for the most jumps, Bridge 2 would hold me for the second most jumps, and Bridge 3 would hold me for the fewest jumps.|
|What materials did you use in your experiment? List them all.:||1. boxes
2. cutting board (or a piece of wood big enough to hold you)
|What procedure was followed? Provide a brief description of the steps you followed during your experiment.:||Step 1: Put your boxes into different types of bridge supports. For example, 1 with supports at each corner, another with supports along the long side of the cutting board, and the other with supports along the short side of the cutting board.Step 2: Get your cutting board. Place it on the first bridge you want to test.
Step 3: Make your hypotheses.
Step 4: Step on the first bridge bridge.
Step 5: If the bridge holds your weight, then start jumping on it. Count how many jumps.
Repeat these steps for all bridges.
|What were the results of your experiment?:||The results of my experiment were:Bridge 1 – could hold me standing and it could hold me jumping for 6 jumps
Bridge 2 – could not hold me standing and could not hold me jumping
Bridge 3 – could hold me standing but could not hold me jumping
|What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect?:||My hypotheses for bridge 1 were correct. My hypotheses for bridge 2 were half-correct. I was correct with standing, but incorrect for jumping. Bridge 3 I was totally correct.|
|Spend a few minutes learning about the scientific princples involved in your experiment. Write 3-4 sentences about what you learned and how it relates to your experiment.:||I learned that different types of bridges could hold different amounts of weight. I also read about a different type of bridge, the jackknife bridge. It is a type of draw bridge. It is used for areas that large ships cannot get past. When a large ship comes, the two sides of the bridge go up so there is an area that the large ship can get past.|
