Residents in Florida and other Southern states probably know a thing or two about alligators. As "deer crossing" signs and "I brake for field mice" bumper stickers fill the lives of Northern residents, folks who live along the Gulf of Mexico find themselves pausing for alligator crossings and braking at the slightest hint of a tail. Perhaps it's that old fashioned Southern hospitality, or a warm climate, but alligators certainly know where to make themselves at home.

See how you did:

9-10 Correct: You sure know your stuff; Fang-tastic.

6-8 Correct: Maybe not perfect, but still pretty good; two thumbs up, and a tail.

3-5 Correct: Only mediocre. If you ever find yourself in the Everglades, you had better watch your back.

Less than 3: Oooh, not very good. Are you a gator hater?

Lets check what ingredient will make water the most dense. We will use seven glasses and fill each with the same amount of water. Make sure the glasses are all the same size and kind. We want to be fair and test this accurately.

Lets get some ingredients:

• Glasses
  
• Water
  
• Salt
  
• Sugar
  
• Powdered laundry detergent
  
• Baking Soda
  
• Flour
  
• Pepper
  
• Graph paper
  
• Egg
  
• Pen

Measure out and pour one cup of water into each glass. Now using a measuring spoon put 1 teaspoon of each of the above ingredients into a separate glass so that one container has water and pepper and the other cup has flour and so on. Each glass has a different ingredient. Stir each one well so that the ingredient dissolves. You may have to stir some longer than others to get it mixed consistently.

Take another glass and just fill with water.

For fun lets use eggs to test this. They are so useful for so many things. Put the egg into the glass with just water. The egg should sink to the bottom of the glass. Record this on your graph paper. You may want to list all the ingredients on the bottom of the graph paper.

Now remove the egg with a spoon and dry off with a paper towel. Lower the egg into the next glass and see what happens. Record if the egg went to the bottom, floated or was somewhere in the middle.

After each cup is experimented, remove the egg and rinse under water and dry off with a towel before proceeding to the next liquid combination.

What ingredient helped the egg float? This ingredient made the water the most dense. Now do the experiment again, but this time pout in 1 tablespoon of each ingredient and see if you have a different outcome.

This is fun to demonstrate at your next science fair.
