Project ideas for kids

Basic but useful projects for kids, which help them to learn important concept of science.

Disaster management System

Disasters are not new for us, they exists from ancient times but with great rise of them from last decade (Katrina & Sandy) we need to find ways to tackle them more effectively.

Homemade Steam Engine

Introduction :

A Steam Engine is a heat engine that performs mechanical work using steam as its working fluid.The first practical steam-powered 'engine' was a water pump, developed in 1698 by Thomas Savery. It used a vacuum to raise water from below, then used steam pressure to raise it higher. Small engines were effective though larger models were problematic.

Fire Ants : Height to Nutrition

Determine the maximum height at which fire ants would come to get food.Set out different types of food and then measured the height that the fire ants came to get that food.

Imported Fire Ant Control Using Household Products

You can use several types of household products to determine which ones controlled fire ants the best. You can use products such as epsom salt, PeptoBismol®, and oranges. You need to made a transect to determine the initial numbers of fire ants in a mound, then present the household product to the mound. Finally, count the remaining fire ants after exposure to the household product.

Glass Harmonica by Ben Franklin

The science behind it has to do with frequency and vibrations. You could make your own glass harmonica of a sorts by pouring water into a set of glasses. Align them to make a row. Fill each of them with different amounts of water (fill each with a little more water ). And then use a spoon and tap each of them in order. They should make a Do Rei Mi sound.

      How to build rocket?

      Air rockets are those which use power of compressed air (pumped using bicycle pump) for their launching.They are different from conventional rockets which gets supply of thrust force in large part of its flight,instead thrust of a air rocket is completely expended in the first instance of flight.They use initial push from compressed air all in once and can fly about 200 to 300 feet.They are simple to build.  To get more information about them and their working you should visit Nasa's Webpage about air rockets.

      Newton laws as they applied to rockets
      Rocket is a missile that obtain from a thrust engine.It is based on Newton's third law of motion which states that every action has equal and opposite reaction.This thrust can be achieved by various ways but one of the most common technique is compressed air. We have already discussed about it in our Air Rocket Post.

      How to build a Catapult?

      Catapult is a device used to throw an object over a long distance.It has been used since ancient times, it has proven to be one of the most effective mechanisms during warfare.It was designed to break or circumvent city walls and other fortifications in siege warfare.

      Cost: Around $ 10


      We should build it in such a way that, it hits it target with accuracy with bare minimum cost.

      Things to consider:

      Trigger Mechanism

      In my opinion, for holder you can choose hole which is smaller than the ball which you are going to throw out.Base should be as large as possible because we need maximum friction below the base and for trigger you can choose any elastic tube, I have read somewhere about medical tubing which is good too.


      As shown above catapult would be build using plywood.Two similar shape plywood will work as an arm and would give support to it. H Shape shown above is used as holder stopper.

      Build a Periscope

      A periscope is an instrument for observation from a concealed position. In its simplest form it consists of an outer case with mirrors at each end set parallel to each other at a 45-degree angle.


      Their are many uses but one of the most common is using it in Submarine, to look outside the water while having completely submerged.

      How to build one?

      Step 1). Take any box

      Step 2). Make two holes , one at the top and other one at the bottom of the box.

      Step 3). Fit two mirrors(not necessarily identical) at 45 degree from their respective base.

      Step 4). Its done!

        Hydrology Project

        Hydrology is the study of the movement, distribution, and quality of water on Earth and other planets, including the hydro-logic cycle, water resources and environmental watershed sustainability.

        Study of hydrology has been investigation and engineering for millennia and using it had changed human life completely.Around 4000 B.C the Nile was dammed to improve agricultural productivity of previously barren lands.In later years Hydrology also gave us Bernoulli's principle . In this post I am trying to give you whatever I found on internet and believes that would be useful for you.I hope you will find these links interesting and noteworthy.

        Study change in hydrological cycle because of global warming.

        Build your own Boat

        A putt-putt boat is a toy with a very simple steam engine without moving parts, powered by a candle or oil burner. Its name comes from the noise this boat makes.It is powered by a very simple heat engine.When we heat the engine which is connected with two exhaust pipes using candle, water starts to become steam and this steam push exhaust tube water forward. In this process, steam get condensed and create vacuum inside the tube due to which water from outside gets pull inside the tube which produce the sound putt.Repeated cycle of above procedure move the boats forward and gives us the impression of engine running with the sound of putt-putt.  Note that in putt-putt boats with two exhaust tubes, the water is expelled from both tubes during the first phase of the cycle, and drawn in from both tubes during the second phase of the cycle. The water does not circulate in through one tube and out through the other.

        Concept used :

        Pop-pop engine with a candle, a heating tank and two pipes (small arrows located at the end of the two pipes try to schematize the circulation of water).

        1. Heat section of Boat using fuel(candle).
        2.Thermostatic Action of Diaphragm pumps water into the boiler.

        3.Reaction of Expelled water propels Boat Forward.

        To get better understanding of this subject, you need to start building circuits on bread board. It is a practical subject and would be much easier to understand when you works on it first hand. Moreover, if you want you start dissembling and reassembling of your old toys and devices, that would give you insight of their working.

        Frequently Asked Question :-

        Q1.How can Stirling engine generate electric Power?
        Ans1.A Stirling engine generates mechanical torque directly from heat through the operation of the Stirling cycle on a working medium, which might just be air.

        Q2.Is it possible to convert a typical combustion engine into Stirling Engine?
        Ans2.The differences in the way the engines are designed to work is massive and the change over would about be impossible.

        Q3. Where to find study Material Required to build Stirling Engine?
        Ans3. Study Material which will help you to make your Stirling Engine Project :
