How To Make A Vinegar Volcano! - Science Fair Projects

Things You Will Need In order to make your own vinegar volcano, you will need - A large sheet of card. A pair of scissors. Some tape. A small funnel. Small plastic bottles (2 Nos.) Vinegar Food coloring Bicarbonate of soda Washing liquid A large plate One pencil. A tablespoon One teaspoon. Step 1 Draw a shape as shown below on a large sheet of card. Be sure that the shape is big enough such that it fits around the bottle. Step 2 Cut the shape out from the large sheet of paper and bend it into a cone shape. Using the tape, you can make sure that the shape stays as it is. Step 3 Fill one of the bottles one-third with vinegar. You can use the funnel to fill the vinegar into the bottle. After that, add few drops of food coloring and one tablespoon of washing liquid. Step 4 Keep the second bottle on top of a plate. Into this, add around 3 tablespoons of bicarbonate of soda using the funnel. Set the cone shape on top

Simple Motor

Aim: To make a simple home-made motor. Materials required: A thick walled paper or plastic cup. Two large metal paper clips. Five small circular or bar magnets. 60 cm of insulated 20 gauge copper wire. Insulation tape. Two code wires- insulated wires with alligator clips on the ends. A 1.5 volt battery or two for better results. Battery holder. Wire stripper. Black waterproof marking pen. Two thick straws. Procedure: Wind the insulated copper wire into a coil with about four or five loops with around 2.5 cm diameter. Leave some length at both ends free. Warp the uncoiled ends around the coil in opposite direction to the loops to keep the coil firmly in place as a coil. Leave 5 cm protruding at both ends after doing this. Use the wire stripper to strip off the insulation at both protruding ends of the coil. Use the black marker to colour one side of one protruding end of the coil. That is, if you turn the wire around you should be able to see the bl

Bead Bowls

1. Oil oven safe bowls 2. Evenly spread beads in bowl and bake at 400 degrees for 10 minutes. Keep your eye on the beads, they cook fast! Take them out when the beads are flat with large holes. When cool, rinse the oil off with tap water and soap. 3. Colorful and playful mini bead bowls

The Dancing Couple

Articles Required : Two long thin needles, a piece of cardboard, a pair of scissors,kfive pieces of cork (one big, four small) and camphor. Make a figure of a dancing couple on the cardboard. Cut it along its outline, and stick it on the bigger cork with glue. Once it's firmly stuck, pierce two needles into the big cork making a 90° angle, to each other. Now on their four ends, insert small corks. Try to make the base as compact as possible. But in any case its diameter should never exceed 5 cm. Stick camphor grains on the sides of four outer corks with the help of pins and place it on water surface. If it has been made as described above, the cardboard couple will turn around and move about—as if the couple has begun its waltz. In order to have a flawless performance, you must remove all traces of oil from the container and corks. You can do this by washing these articles well with hot water mixed with soda.

The Umbrella Dance !

Articles Required : An umbrella with a "U" handle, a bottle in which umbrella handle can be inserted, string and a piece of chalk. First rub the chalk on the string. Tie this string loosely to two points of opposite walls of a room. Now insert the umbrella handle in the bottle," and try to balance the bottle on this string. Once you've found the balancing point, your job is over. Now as you give it a light jerk it will start dancing like an acrobat—going up and down in a funny manner

Sunspots

Aim: To make a simple apparatus to view sunspots without harming your eyes. Materials required: A sheet of white paper. A telescope or if telescope is not available, a shoe box with a hole on one of the ends. Procedure: Hold the white sheet of paper in your hand or clip it onto a clipboard. Point the objective lens of the telescope towards the sun and the eyepiece towards the sheet of paper so that you get a circular image of the sun on the paper. Adjust the focusing knob on the telescope to get a sharp image. Observe and see if you can see dark spots on the bright disc like image of the sun. You may have to do the experiment on several days to see these spots. If you do not have a telescope available, simply make a hole in one end of a shoe box and face the side with the hole towards the sun so that the image of the sun falls on the opposite side of the shoebox. Scientific explanation: The sun is not uniformly of the same temperature. Some spo
