Feet :: A Smelly Science Fair Project

Can you tell a person’s gender by looking at their bare feet? You may think it's obvious, but surprisingly, it isn’t. This district-winning school science fair project is super fun…that is, if you’re not afraid of feet (honestly, it’s a real fear!).

Step 1: Create a Hypothesis

The purpose of this project is to determine whether you can recognize a person’s gender by looking at pictures of their bare feet[/kwlink]. Based on this, you need to create a hypothesis (or prediction). For example, you may predict that…

  • the older the person, the easier it is to identify their gender by looking at their feet
  • female feet are easier to identify than male feet
  • male feet are easier to identify than female feet

Those are three options for a hypothesis. But the choice is up to you.

Step 2: Gather Your Materials

For this project, you’ll need the following:

  • 20 volunteers who will let you take pictures of their feet
  • Camera
  • Black poster board
  • Post-it notes
  • Felt pen
  • Survey chart to record your data
  • 50 people to survey

Step 3: Follow the Procedure

  1. First, you need to find 20 volunteers who will let you take a picture of their bare feet. You’ll need 10 males[/kwlink] and 10 females ranging from ages 7 to 14, as well as two teenagers and two adults. Make sure you have one male and one female from each age group.

  2. Ask each volunteer to stand on a sheet of black poster board to make the pictures consistent. Place a numbered Post-it note in front of their feet so you can keep track of which feet belong to which age and gender. Then take the pictures. (Make sure no one is wearing anklets, toe rings or nail polish).

  3. After you develop the film, find 50 volunteers to survey. Show them each photograph and ask them to guess whether the feet belong to a male or female. Record their answers on a chart. For each picture, keep track of how many people guessed right, and how many guessed wrong.

Step 4: Gather Your Results

Once you complete the survey, you can compare your results to your hypothesis. Did most people guess the right gender when the feet belonged to someone older? Were female feet easier to identify? How about males? Remember, it’s okay if your hypothesis turns out to be wrong. After all, if we knew the answers, we wouldn’t need to experiment.

Do Your Feet Stink?

  • Yeah, they stink. I admit it.
  • Only if I don't wash them for a week.
  • My feet never smell bad.
  • I don't know.

Love it or hate it, the crazy theory of Flat Earth is gaining a lot of popularity and movement world wide. What's your opinion? Remember, regardless of what anyone says, keep an open mind and don't bash. I'm curious to see why people believe the way they do, or if they have facts and evidence to support their claims. So, do you believe the Earth is flat....or spherical?

No, AlphaT won't be missed. And he totally isn't tearing up right now.  Thank you. I know it sounds unoriginal, but getting to know all of you has been an absolute privilege. Each of you made my time here worthwhile, and it's nice knowing that I've done the same for you all.  Goodbye!

You know, I agree with your theory. I don't think I can put it into the well-thought and eloquent wording you did, but as vast as the human mind is, each individual one has its limits. Everyone clearly thinks different of what is wrong and what is right - Hitler did think that his actions were a good thing, didn't he?  The most evil thing I could think of certainly isn't KW appropriate. Then, expanding on that further, I figured that murder is probably one of the worst things a human can do. But then that got me thinking: what  if it's the other way around? Or, what if there is something even worse than both of those? Everything else that came to mind probably, most likely, isn't a KW kind of topic - and I'm sure my brain can't even come up with everything else disgraceful. Therefore, I don't think I can determine which is worse, as there are many things I find putrid - and some I can't even think of - and they're all quite horrible. So then the most good thing I thought of was angels. They're pure and holy, right? What can be even greater than that? The Lord, of course. To someone who believe ins Him, who or what is more just and righteous than that? This got me wondering what those who do not believe in Him would say. Charity work, perhaps? A newborn child who is yet to have experienced the awfulness of the world? An innocent domestic animal whose perception of the world is far different from ours? This was definitely really thought-provoking. I might have to think about this further sometime in the future.
