Though there are a few different ways to create a tornado model for a science project, the easiest way is to use water, plastic bottles and a few other common household items. Complete the project in less than an hour.Know More
Find and clean two 2-liter plastic bottles. Remove any labels or debris that makes it harder to see inside the bottles. You also need duct tape, a pen or another tool of that size to create a hole, a pair of scissors and water.
Cut a piece of duct tape large enough to cover securely the opening of one bottle. Puncture a hole in the center of the duct tape. Place the duct tape over one opening, and then use more tape around the side of the bottle opening.
Add water until the second bottle is three-quarters full. Do not place any tape over the opening of the second bottle.
Place the empty bottle upside-down on top of the bottle filled with water. Carefully inspect that the openings of the bottles match. Fashion the two bottle openings together with more duct tape. Test for leakage by lying the bottles flat. To create the tornado effect, flip the bottles so that the one with the water is on top. As the water filters through the hole, it looks as though there is a tornado. Swirl the bottles for an extra effect.
To make paper airplanes for a science project, paper of varying thicknesses should be used to determine which is the most effective. These might include copy paper, construction paper or other heavier paper, as well as paper clips for experimenting with weights. The basic model is made by folding copy paper. Variations on the design are then created and the flight results recorded so that they can be compared with the original.Full Answer >
To make acid rain for a science project, use vinegar or vinegar dissolved in water. Change the concentration of vinegar in the solution to imitate more or less acidic rain.Full Answer >
According to UCAR, Center for Science Education, to make a tornado model you need an 8-ounce jar with a lid, water, vinegar, clear liquid dish soap and a pinch of glitter. UCAR provides instructions for constructing the model.Full Answer >
A science project that explains the blue color of the sky at certain times of the day can be done by projecting a beam of light from a flashlight or a projector through a transparent container, like a large beaker or a jar, filled with a mixture of water and some powdered milk. The beam appears bluish-white when viewed from the sides of the container.Full Answer >
