FOG TORNADO
A tornado is funnel shaped column of wind that is created by...
Question: Does the size of the box effect the tornado's movement?
Hypothesis: We predict that the smaller box will have a small tornado and the big box will have a big tornado
Our Experiment
Materials:
|
Safety Procedures:Adult supervision at home required Hand wear required for dry ice The stages of a tornado: Dust-Whirl A dust cloud forms in the whirling air at the surface. No funnel cloud or just a small stub of a funnel cloud is visible. A vertical shaft of whirling air is present, but it is largely invisible as condensation has not yet formed clouds which make the funnel visible and insufficient dust has been picked up at the funnel's base to make anything but that portion of it nearest the ground visible. If the storm strengthens... Organizing The winds increase. The funnel fills in. The funnel becomes more opaque, mostly from water droplets at its top and from dust and debris at its base. Contact with the ground may be intermittent. Mature The tornado acheives its maximum strength. The funnel reaches its maximum width. It is nearly vertical and nearly symmetric. Contact with the ground generally persists through the mature and dissapating stages. Dissipating or Shrinking The funnel begins to shrink in width as its damage swath also narrows. The funnel may begin to tilt. Wind velocities decrease. Damage caused by the tornado begins to decrease, but may still be severe. Rope or Decay The tornado gradually weakens and becomes increasingly contorted until it completely dissipates. The dissipating funnel often takes on a ropelike appearance. |
Procedure:
- Make Hypothesis
- Gather Materials
- Build Box
- Paint Box
- Place a Plastic Bowl in the Box
- Put the Dry Ice in the Plastic Bowl
- Pour Hot Water into the Plastic Bowl
- Turn on the 12 Volt Computer Fan
- Repeat Steps 3 - 7 but With a Different Size Box
- Record Results
- Conclude results
The Science behind it
The fan forces air out of the chamber, air from outside the box is forced in through the slots on the sides. The position of the slots causes the incoming air to create a VORTEX (spiral) of air as it is drawn up and out of the box. Real tornados form in a similar way using updrafts and wind-shear.
Conclusions
We reject our hypothesis because we concluded that a big box has a small tornado and the little box has a small tornado.

Meet Sam and KevinWe are great buds and barely argue. We share our ideas/ thoughts and talk about explanations to our ideas.
