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.

Easy school projects on solar energy and power

Solar energy can be used to heat our homes and do so much more. solar energy is being used as conventional source of energy to do so much more than just light a few bulbs. Once you have to demonstrate your school science project on solar energy there are many options to go for. Here we are listing 5 Easy school projects on solar energy and power which are easy to make and easy to demonstrate.

5 Easy school projects on solar energy and power :

  1. Solar powered fan

Easy school projects on solar energy and power

A simple school science project which can demonstrate the energy conversion from solar energy to electricity. This project needs a solar panel to collect solar energy and DC  toy motor to attach to it. Once taken out in sun, the circuit is completed and it works like a pro. Attach the fan blades or plastic toy fans easily available to complete this school project after completing the circuit of solar powered fan.

  1. Solar powered car

The simplest of all the science projects to make all you need is aluminium foil and shoe box covered with foil and black chart paper to convert solar energy into heat energy to slow cook the food. Once the sun rays are concentrated on the solar cooker it increases the inside temperature of the solar cooker.

  1. Solar water heater

This solar power school project is a little tricky and works best for students of grade 9 and above. You will need soft copper pipes and soldering iron to make one.

You will need to paint the copper tube black.

The copper pipes are fiited in the solar panel which is usually made of glass and cool water once passes through copper pipes gets heated and gets collected into an outer chamber. The base of the solar panel can be made with aluminium foil to collect more sun rays.

5 facts about wireless power transmission we are sure you did not know about

Wireless power transmission has been around for a while but off late it has picked up a lot of momentum. Wires are a hassle and if gadgets can be wireless then it saves a lot of space and ugly wires.

We are still waiting for a breakthrough technology in wireless transfer of energy which can solve the problem of longer distance. If that becomes a reality, world will soon see a revolution around wireless energy which will be powered by Wi Fi routers and will be easily available at public places.

This can be made into a school project try our do it yourself wireless power transmission kit to tacch this great technology of the future to children.

Facts –

  1. There are two ways of wireless charging one is inductive and magnetic charging and other is by radio frequency energy.
  2. Wireless energy is already being used to charge electric toothbrushes, it much safer as their proximity to water. The conventional wire charging is considered a hassle.
  3. The discovery of the basic principle was done by Michael Faraday back in 1931. Legendry scientist Nikola Tesla was already doing great experiment using the same principle.
  4. Wireless charging can reduce CO2 emissions and are much more sustainable.
  5. Not only phones but soon all of the technology would be working on wireless charging that will include electric cars as well.
