School science project on making model of thermometer

Teaching units of measuring temperature can be fun with this simple School science project on making model of thermometer leads a clear understanding of the subject.

Thermometer is a measuring instrument to measure the degree of hot and cold. The heat energy is the form of energy which moves from hot particles in the substance to the colder particles. When material is hot its particles move much faster than when its in a colder state. Thermal energy is the sum movement of kinetic energy of the particles.

Daniel Gabriel Fahrenhiet, a German scientist introduced first thermometer in the year 1709. It contained alcohol. The thermometer filled with mercury was made in the year 1714.

Many types of thermometer are used these days but the most common method is to use thermometer filled with mercury. Since mercury is a health hazard and not safe for children to use in school science project. There are other options to make school project on thermometer such as liquid filled thermometers coloured with vegetable dyes.

Material needed to make this school science project :

  1. Clean plastic bottle
  2. Rubbing alcohol
  3. Plastic straw
  4. Modelling clay

Procedure

Put water in the bottle, fill it to one fourth

Add rubbing alcohol to the bottle till the bottle is half full.

Then add a few drops of food colour to the mixture in the to make it visible

Add the straw in the bottle, make sure it doesn’t touch the base of the bottle

Lock the mouth of the bottle with the clay and let it settle for sometime at room temperature.

Stick a card  stock paper to the outer end of the straw and mark the point where the liquid is right now and that can be taken as room temperature.

Next place the bottle in the sun and see the temperature rise accordingly.

This is fun science project to do in the school as well as home and teaches about scales of temperature.

How to make a penny battery, Voltaic Pile easy science Project

How to make a penny battery is a simple science project to understand the generation of electricity is one of the easiest to make and the raw material is available.

This simple school project uses two different types of metal which is stacked one on top of other and use some salt water or lemon drops to make a voltaic pile.

These kind of simple batteries convert chemical energy to electrical energy and generate small volts electricity. The higher the stack then higher is the voltage produced which is enough to light up one small LED of 1.5v.

Zinc and copper are the materials generally used for this school project. Zinc nails and copper wire can also do the trick.

Usually pennies are used. They are first sanded with sandpaper on one side so that zinc can come to surface and the other side is usually left free. Copper side is faced down and zinc side faces up and in between them a tissue paper soaked in salt water solution or lemon juice is used. The stacking is done the same way by placing copper side of the penny again on the zinc side with tissue paper soaked in sour solution to complete this science project.

Vinegar can also be used to soak tissue paper to make the pile. The stack can be as big as 12 penny pieces to generate minimum voltage to give electricity to light up LED.

It usually takes 7 to 8 hours for electrons to start flowing for science project to work. The tissue paper should not dry in the process and is kept wet with the sour solution.

The stack can be made higher once the voltage is checked from the multimeter.

There is another variation to this whole project as in India the pennies are not easily available we can use zinc nails and copper wire to compete the project.

This simple project is based on the same principle and once assembled is good to light up LED of 1.5v.
