Have you ever wondered how heat travels through different metals? In this fun experiment, we explore how well different metals conduct heat. Conductivity is a property that tells us how easily heat can move through a material. Some metals are better at conducting heat than others, and we’re going to find out which ones are the best!
For this experiment, we have a special device with five metal rods. Each rod is made from a different type of metal: steel, brass, nickel, aluminum, and copper. All the rods are the same thickness and length, so we can compare them fairly. At the end of each rod, there’s a candle attached with wax. The wax will help us see how fast the heat travels through each metal.
We start by heating the center of the device with a burner. As the heat travels through the rods, it will melt the wax holding the candles. The candle that falls first shows which metal conducts heat the fastest.
As we watch, the candle on the aluminum rod falls first, followed closely by the candle on the copper rod. This means that aluminum and copper are excellent conductors of heat. Next, the candle on the brass rod falls, showing that brass is also a good conductor, but not as good as aluminum and copper. Then, the candle on the nickel rod falls, and finally, the candle on the steel rod falls. This tells us that nickel and steel are not as good at conducting heat as the other metals.
From this experiment, we learned that different metals conduct heat at different rates. Aluminum and copper are the best conductors among the metals we tested, while steel is the slowest. Understanding heat conductivity is important in many real-life applications, like cooking, building, and even in electronics!
We hope you enjoyed this experiment and learned something new about how heat travels through metals. Keep exploring and discovering the amazing world of science!
Imagine you’re a scientist conducting the same experiment! Create a chart to predict which metal will conduct heat the fastest. Then, watch a video of the experiment and compare your predictions with the results. Discuss why some metals conducted heat faster than others.
Draw a colorful diagram of the experiment setup, labeling each metal rod and the order in which the candles fell. Use different colors to represent the speed of heat conduction for each metal. Share your artwork with the class and explain your findings.
Think about items you use every day that involve heat. Make a list of at least five objects and identify the metals used in them. Discuss why those metals are chosen based on their heat conductivity properties.
Become a metal detective! Research and find out why aluminum and copper are used in specific applications, such as cooking pots or electrical wiring. Present your findings to the class, highlighting the importance of heat conductivity in these uses.
Write a short story about a day in the life of a heat particle traveling through different metals. Describe its journey and how it feels moving through fast conductors like aluminum and copper compared to slower ones like steel. Share your story with a partner.

Heat conductivity of different metals: how can we compare the heat conductivity of various metals? Metals can have different properties. In this investigation, we will explore how metals differ in terms of heat conductivity.
This device consists of five types of metal rods of the same thickness and length: steel, brass, nickel, aluminum, and copper. At the tip of each metal rod is a candle held in place with wax.
How will heat move when the center of the device is heated with a burner? Which type of metal will be the best conductor of heat?
Here goes aluminum and copper. Which will be next? Brass. Which do you think will fall next, nickel or steel? Good guess, it’s nickel. And finally, steel.
That was fun! See you next time, and don’t forget to subscribe!

Heat – Heat is a form of energy that is transferred between objects with different temperatures. – When you touch a warm cup of cocoa, you can feel the heat moving from the cup to your hands.
Conductivity – Conductivity is the ability of a material to allow heat or electricity to pass through it. – Copper is often used in electrical wires because it has high conductivity.
Metals – Metals are materials that are typically hard, shiny, and good conductors of heat and electricity. – Metals like iron and aluminum are used to make many everyday objects.
Experiment – An experiment is a scientific test carried out to discover or demonstrate something. – In our science class, we did an experiment to see how different materials conduct heat.
Aluminum – Aluminum is a lightweight, silver-colored metal that is a good conductor of heat and electricity. – Aluminum foil is often used in kitchens because it can withstand high temperatures.
Copper – Copper is a reddish-brown metal known for its excellent conductivity of heat and electricity. – Copper pipes are commonly used in plumbing because they do not rust easily.
Brass – Brass is a yellowish metal made from copper and zinc, known for its durability and acoustic properties. – Many musical instruments, like trumpets, are made from brass.
Nickel – Nickel is a hard, silver-white metal that is resistant to corrosion and used in alloys. – Nickel is often used to make coins and batteries.
Steel – Steel is a strong, durable metal made from iron and carbon, used in construction and manufacturing. – The bridge was built using steel to ensure it could support heavy loads.
Science – Science is the study of the natural world through observation and experiments. – In science class, we learned about the different states of matter: solid, liquid, and gas.
