Investigate The Possibilities Experiment Challenge


     I am really excited about doing this experiment Investigate The Possibilities Experiment Challenge. here is the link.  http://thehomeschoolscientist.com/  I am experimenting on bending streams of water. Here is the picture of the things you need and the list:  


       A Rubber balloon, Bottles ( that will form a stream of water, Paper  (torn into little pieces), Pieces of wool or fur,  string, scissors, one inch Styrofoam ball, (two) one half inch Styrofoam balls, Four tooth picks , and finally a tetrahedron. The experiment didn't show a pattern for one but I found how to make a tetrahedron out of a envelope at this website: http://tremor.nmt.edu/activities/origami/tetra.html 
 Now here is how you do the experiment:
     Charge a rubber balloon by rubbing your wool over it. Next move the balloon over the small pieces of paper. Did some of the paper move? 

       Touch your hand firmly on the balloon in some places. Place  over the paper. Did the paper move again? I guessed that the paper moved because of the static electricity the first time but when you rubbed the balloon it took all of the electricity away and it did not cause the paper to move. When I did this experiment the balloon charged by the fur caused the paper to move around a little. But when I rubbed my hand on the balloon it didn't move the paper.

     The next experiment was to see if charging your balloon and putting the charged balloon by a steady stream of water like this: 

      See if the water bends. I guessed that the water would bend because the balloon was charged by the fur and caused electricity in moving the water. 

      For the last experiment you need your tetrahedron. Here is a picture of it: 
   
      After you have your tetrahedron you need four toothpicks, and one inch Styrofoam ball. (I used to packing peanuts and taped them together for the one inch ball and they worked okay.) Then you open your tetrahedron like this:

     Then stick your one inch ball into the tetrahedron and close it back up. Next you want to stick a tooth pick in the top of the tetrahedron and push it slightly through the Styrofoam ball where the top of the tooth pick is sticking out of the top. Then you need to do that again but this time do it in the three corners where the stick into the ball. Then you need to open the tetrahedron and take the Styrofoam connected to the toothpicks out it should look like this:  

The instructions I got for this were a little hard but I will explain them a little better. you need your one inch all and both of your one half inch balls take the toothpicks off of the one inch Styrofoam ball then place your half inch ball on the top right side of your ball. Then stick one tooth pick into the one inch ball and the one half inch ball then place your other ball on the top left corner of the one inch ball stick the tooth pick in. once both of the half inch balls are on the one inch ball it should look like a teddy bear face. this teddy bear face represents a water molecule the one inch ball is the oxygen, and the two half inch balls are the hydrogen  
Here is my teddy bear except I had to use Styrofoam packing peanuts because we didn't have Styrofoam  balls but Styrofoam peanuts work just as well but the bear is kinda pointy.

    I really enjoyed doing this Experiment it was a lot of fun.

  1. It sounds like you really enjoyed your experiments! The analogy of the teddy bear head for the water molecule is right on! I never thought of it that way, but I will probably always think of the teddy bear from now on :) Thanks for participating in the challenge.
