Science fair projects are helpful in finding answers to various questions. The realm of science is huge whereby it is extremely fascinating to seek answers. With science fair projects, one tends to learn about the basic principles of how things work. With a science fair projects, one needs to develop one’s own question, seek help from literature guides, form an hypothesis and carry it forward with experimentation and designing of the overall data. The data is gathered and scrutinised further for finding appropriate results. With a science fair projects, one tends to develop skills and learn a lot. If you are worried about a science fair coming up with no plan in mind, here are few easy science fair projects, to get you started-

  1. Making a windmill

    Making a windmill as your science fair projects is a great option if you want to explain the basic fundamental of wind energy. Windmills and wind turbines use wind energy for driving a generator. Since wind energy is a sustainable source of energy, there are no harmful radiations or emissions from it and can never be exhausted.

    All you need for this science fair project are-

    • Pencil
    • Ruler
    • Scissors
    • Adhesive putty
    • Heavy construction paper
    • Straw
    • Metal paper fastener

    To begin with this science fair projects, you can start by-

    • Make a ball of one inch from adhesive putty into your hands and keep it aside for the time being.
    • Take the heavy construction paper and cut it down into a square shape. Fold it diagonally in order to make a triangle. Then repeat the same step on another side so that when you open up the paper, there are crease marks on the paper showcasing an ‘X’.
    • Take the ruler and measure one inch from the centre of the paper or X. Do this on all four sides and mark it with the pencil. Now cut the lines marking to the pencil line.
    • Fold the corners and pull the paper to the centre. You should fold the tips of the triangles evenly.
    • Now use the metal paper fastener on the centre of the paper.
    • Take the straw and insert it into the adhesive ball putty. Flatten it to be levelled up on the ground. Then use the stick the paper’s centre on the other end of straw in order for it to rotate.
    • Blow gently on the windmill and see how it spins.

    This science fair project teaches the importance of wind energy and how it can be used for generating electricity. It can also be used for powering water devices etc. Energy derived from wind is renewable resource and should be utilised more efficiently.

  2. Water clock

    This science fair project might seem a little strange to you but it can be made. Back in the ancient time, water clocks were used for measuring time. Water clocks were accurate and predicted time for daily use.

    All you need for this science fair projects are-

    • Styrofoam cup
    • Stopwatch
    • Pushpins
    • Clear jar
    • Masking tape
    • Pen

    To begin with this science fair project, you can start by-

    • By using the pushpin, make a hole in the middle on the Styrofoam cup right at its bottom. Not push the pin’s tip through the bottom of the Styrofoam cup inside out.
    • Use the masking tape and put a piece of it straight up to the side of the clear jar. At an interval of 1 cm, make lines from the bottom.
    • Now use the Styrofoam cup and insert it into the mouth of the jar (if the mouth is big, otherwise you can also tape the two together).
    • Take water and fill up the cup to the brim.
    • When the water starts dripping, use the stopwatch to record the amount of time it takes in order for the water to reach the level of the first line on the jar. Make recordings till the time the water from the up is all empties up and there is nothing more left.
    • Now, you can also decorate the water clock if you wish to, like the ancient people used to do. Or you can leave it as it is and demonstrate this project.
  3. Volcano

    What is a science fair without demonstration of an exploding volcano? This science fair project deals with showcasing the working of a volcanic eruption which pushes molten rocks out of the Earth’s surface.

    All you need for this science fair projects are-

    • Liquid detergent (ten to fifteen drops will be enough)
    • A big plastic bottle (cleansed out completely)
    • Warm water (not the boiling water)
    • Sodium bicarbonate
    • Bottle of strong malt vinegar
    • Wallpaper glue
    • Piles of old newspaper
    • Red food colouring

    To begin with this science fair projects, you can start by-

    • Take the newspapers and tear it apart into small lines or strips.
    • Dip the strips of newspaper into glue and make a paper mache. Mix the newspaper and glue together and form dough. Now use it to make a volcanic shape.
    • Use the bottle and shape up your volcano completely. Stick newspaper glue mache to it and make the cone look.
    • Now, fill up the bottle with warm water and add some drops of dark red food colouring to it. Add as many drops as possible for the real effect. To this mixture, add ten to twelve drops of liquid detergent.
    • Now, carefully add up a lot of sodium bicarbonate to the mixture.
    • Keep the surface area clean and devoid of any precious things before adding up vinegar to the mix. Watch and observe the volcano eruption!
  4. Transferring egg to the bottle

    Who would have thought that a simple egg can do the trick of becoming one’s subject for science fair project? This experiment showcases the use of oxygen molecules for creating a reduction in air pressure. The particles move owing to the difference in air pressure. The amount of affected area and pressure in air determine the amount of pressure exerted.

    All you need for this science fair projects are-

    • Boiled egg of medium size (you can do this by boiling the water along with eggs on a gas for 10 to 15 minutes.)
    • A bottle which has a neck smaller than the egg.

    To begin with this science fair projects, you can start by-

    • Take the bottle and hold it under the hot tap water for 40 to 50 seconds before placing the egg on the top of the neck of the bottle. Let the water cool down and it would magically suck the egg inside it.
    • You can also remove the egg from the bottle by titling the bottle and letting the hot water run down in the bottom.
  5. Potato clock

    Potatoes act as great conductors of electricity. A potato clock is a brilliant example of a clock that does not require any batteries- only potatoes. All the materials required can be found easily at any hardware department store. This experiment is an attempt to recreate an electrochemical cell which is used to convert chemical energy into electrical energy.

    All you need for this science fair projects are-

    • Marker
    • Big size potatoes – 2
    • Wire cutter or sharp regular scissors
    • Copper wire
    • Digital LED clock using AA or AAA type of battery
    • Two galvanised nails
    • Three jumper wires including the alligator clips

    To begin with this science fair projects, you can start by-

    • Take the two potatoes and name them A and B respectively by the help of a marker. Now cut two equal lengths of copper wire by using the wire cutter. The two pieces should be of five centimetres long.
    • Take the clock and remove batteries from it. You don’t require the batteries, only clock.
    • Insert half of a galvanised nail inside the A potato. Repeat the same thing with the B potato. Do not insert the entire nail, just half.
    • Now take the copper wire and insert it inside the potato like done previously with the nail. But make sure that the nail and copper wire are far away from each other and do not touch, even on the insides of the potato.
    • Take the first jumper wire and connect the copper wire of the first potato A to the ‘+’ or positive terminal of the battery compartment given in the clock.
    • Now take the galvanised nail from potato B and connect it to the negative or ‘-‘ terminal of battery compartment in the clock.
    • Now again connect the potato A’s galvanised nail and potato B’s copper wire by using the third jumper wire.
    • What you would immediately notice is that the LED clock has started showing time! The potato clock is ready to work.
