When materials are added to the surface of a ramp, which material will cause the OREO to roll the furthest?

Materials: 1 board 3 books (1 inch?) Take the books and put them in a pile, then place board so it looks like a ramp and is a ramp. ScienceNetLinks ( http://www.sciencenetlinks.com/lessons.cfm?DocID=21 ) This helps me understand my project more because it tells me how to build a ramp. No other website that I could find had how to build a ramp! I needed to know how to build a ramp because I did not know how to and the OREOs need to go down a ramp. ||  ·   spray bottle with water in it   ·    sand  ·   zout soap  ·   ruler  ·   recording sheet  ·   3 OREOs  ·   A few books that __altogether__ equal 3 inches  ·   3 pieces of cardboard || 2. Make 1 ramp using the research above. 3. Spray it with water a few times then put one OREO down the ramp. 4. Change the board, and then put zout on it. 5. Repeat step 4 only this time put sand on the board. 6 .Record your data (which OREO rolled the farthest, 2nd farthest, etc.) on the recording sheet 7. Repeat steps 1-6 2 times 8. YOU ARE DONE!!!!!!!!! ||

 * Problem || When materials are added to the surface of a ramp, which material will cause the OREO to roll the furthest? ||
 * Hypothesis || I think that the water will make the OREO go the farthest because, like tires it might pick up speed and go further.  ||
 * Materials || 
 * Procedure || 1. Get all the materials listed.
 * Data Collection || [[file:Recording Table.doc]] ||
 * Conclusions || My hypothesis was right because every time I did it, the OREO that was rolled down the ramp with water went the farthest. The second farthest was always the Zout. I didn’t expect that because it was sticky (I had sticky hands after the experiment!). The last one was always the sand, which I kind of expected because at first the sand OREO would not even go off the ramp! I realized that you needed to change the OREO every once in a while so that it would go down the ramp. Something I needed to put in my procedure was that you had to find a clear space to do the experiment because the OREOs kept hitting objects. Also, I had to tape the board to the books once. I forgot to put the part where you repeat 2 times in the procedure. Overall, I learned that if you want something to slide down a ramp, use water. ||
