## Demonstrate convection currents & Compare rate of conduction of heat in different metals | School Science Projects

• Perform an experiment to understand the concept of heat and temperature.
• Make a setup to see how rate of heat transfer varies in different materials – Conduction
• Make a setup to see heat transfer in liquids & gases – Convection currents in action
• Make a thermometer & understand its working principle – expansion of fluids on heating

Measure the seemingly immeasurable!

Before the thermometer was first invented in the 17th century, the thought of measuring heat would have surprised anyone. Ever since then, temperature has been as easy to measure as body weight. Measuring heat has also been important to understand the concept of convection and conduction currents, and the transfer of heat to create sea breeze and land breeze. But thermometers have always been considered as industrial or medical devices that can only be purchased and not constructed domestically. As Science always breaks barriers, at Butterfly Fields we break this barrier by teaching your child how to make their very own thermometer by using our provided apparatus in the Do-It-Yourself Thermometer Kit!

This DIY project instructs the very important following lessons:

• Understand the concept of heat and temperature by performing an experiment consisting of balloons, Styrofoam balls, a glass, and a rubber apparatus.
• The rate of heat transfer by using of candle wax, metal strips, pins, tape and more rubber apparatus to make a setup that implements rate of heat variation in different materials by the process of conduction.
• Next, your child will learn how to make a setup to see heat transfer in liquids & gases by the process of convection currents that are put into action by using pipes, tape, incense sticks, plastic paper and rubber apparatus.
• Your child will learn how to make a thermometer & understand its working principle i.e. the expansion of fluids on heating. This experiment consists of a balloon, colored water, a test tube, a pipe, a rubber pedestal and a paper card for depiction, all used to create the thermometer.

These concepts are very critical to a student’s syllabus, as it consists of basic fundamentals that are integral to understanding heat, transfer of heat in liquids and gases, convection currents and expansion of fluids. Butterfly Fields provides students the opportunity to understand and rejoice these science concepts with fun activities that improve the child’s 21st century skills, collaboration, creativity and problem-solving abilities.
