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 :
- Clean plastic bottle
- Rubbing alcohol
- Plastic straw
- Modelling clay
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.
