The+Attacking+Lid

= = __The Attacking Lid__ The Attacking Lid consist on hiting a lid of a baby's food jar and see what happens after. We need to build something to measure the distance that the lid traveled (sidewards) and do a chart.

Materials:

 * 2 rubber bands
 * lid
 * baby's food jar
 * clothing pin
 * half of clothing pin
 * brain

Aim:

 * Measure the distance did the lid traveled (sidewards) after being hit. Why only that much did the lid went? do a chart.**

Theory:
depending on how much we pull the clothing pin is how much the lid is going to go.

We could change...

 * angle
 * force
 * lid for another thing

We could measure...

 * distance
 * force
 * mass
 * size

Process:

 * 1) Take off the lid from the jar and put it on top of the jar without closing it completely.
 * 2) Put the 2 rubber bands round the jar.
 * 3) Attach the clothing pin with the half clothing pin to the 2 rubber bands.
 * 4) Pull the clothing pin (to hit the lid) and let it go.
 * 5) Look at your built ruler and see how much up did it go.
 * 6) Do a chart.
 * 7) Try this with different forces and write them in the chart.

Conclusion:
We don't do our experiment yet but we are not going to do it, we'll do another one that my group and I invented based on this idea. Check some information about is in my page "The Attacking Marble".
