Hypothesis Based on Data (Marching Study)

Before I started this study, I knew that there was a physical difference between marching and walking.  I suspected that the motion of a person's foot varied from marching to walking.  This is not entirely true.  I did not observe any marked difference between the two activities when I tracked a person's foot.  However, this does not mean that there is not a physiological difference betwen marching and walking.  When a person marches the goal is to "float" on the ground.  The body should not bounce with each step.  It should simply glide across the ground.  I suspect that this is due to a change in a person's core muscles.  There are 29 muscles within a person's core.  If they are activated, the body can do amazing things.  Based on this, I believe that the difference in marching and walking can not be attributed to the change in motion of a person's foot, but rather the activation of the core muscles.

Marching Study Pictures

I took some pictures tracking documenting my research.  They are in a Picasa album.

Marching Study Data

I have finished my research in my marching study. Here is a hyperlink to a google doc of my data.

Candle Lab Prezi

Here is the presentation that we created using Prezi for our candle lab.

Candle Lab Pictures

Here are pictures of the candle labs.  My group is shown in the pictures with the hot air balloon we created.

Harwood Model for the Candle Lab

Here are the steps we went through for this lab.  We used the Harwood Model.

1. Defining the Problem
2. Forming the Question
3. Communicate with Others
4. Investigating the Known
5. Articulating the Expectation
6. Carrying Out the Study
7. Make Observations
8. Examine Results
9. Reflect on Findings
(At this point our experiment did not work correctly.  We had to follow the process again.)
10. Defining the Problem
11. Communicate with Others
12. Investigating the Known
13. Defining the Problem
14. Carrying Out the Study (We started revising our study, but did not have time.)

Candle Experiment

Research Question: Can you create a hot air balloon on a small scale using a candle?

Hyphothesis: We expect the heat generated from the candle to cause the air in a balloon to heat up and rise.

Procedure:

http://www.wikihow.com/Make-a-Mini-Flyable-Hot-Air-Balloon-with-Candles

1. Make circle brace out of straws
2. Attatch to bottom of plastic bag
3. Attatch candles to small piece of cardboard
4. Attatch string from cardboard to the bag
5. Light candles

Materials:

• Thin platic bag
• Birthday candles
• Straws
• Thin cardboard
• Super glue
• String
