How to do a simple heat conduction experiment

Sharing is taking care of others!

How many of you parents are extremely comfortable teaching science? And I mean unusuallycheap.

If you’re not, you’re not alone! I’m not much of a science buff myself. I got good grades in it as a kid, but I haven’t really ever been interested in it.(Z wyjątkiem astronomii. Astronomia jest niesamowita.)

So when it comes to science education, I struggle to understand the concepts in order to teach them to my children. And that’s why I was thrilled to have the chance to review a great science book and try out some of the activities, including a simple heat conduction experiment!

Read on to find out why I enjoyed this book and to see one of the hands-on activities contained in it!

How to do a simple heat conduction experiment

Scientific concepts for the unscientific parent

As I mentioned earlier, I’m not super comfortable with science. And what’s worse – I’ve forgotten most of what I did learn in school. Fortunately, I’ve recently gotten a copy of the book Air Is Not Oxygen: Essential Science You Should Have Learned … But Probably Didn’t! and I have to say: this is fantastic.

It’s a comprehensive overview of different science concepts, including light, heat, animal behaviors, and more, so it’s a good introduction or reintroduction to the same things you and I learned in school.

I’ve had so many “Ohhhhh!” moments of reading this book. For example, when Dr. Morelan talks about heat, he explains that it is possible to produce heat through physical or chemical reactions by stirring them in the air (cooling them).

Have you ever thought of it as friction or as an example of heat generation? I didn’t!

And the book is written in a witty and colloquial way that just …Does this make sense.I actually found my husband reading it later. That’s how beautiful it is.

A simple heat conduction experiment

After reading the section on how heat is generated in babies, we tried one of the experiments in the book to observe heat conduction in action.

What is heat conduction? It’s how heat travels from one object to another. Na przykład, kiedy dotkniesz czegoś wykonanego z metalu, jest mu zimno, prawda? Do I know why?

Because metal sucks the heat out of your body! Seriously! Kolejną rzeczą, której nauczyłem się od Air, jest Not Oxygen.(Seriously, buy it now. You’ll be glad you did.)

It turns out that metal is an excellent conductor of heat. To test this, the book recommends experimenting by comparing it with two other materials to see which is the best conductor of heat. We took the butter and spread it on a plastic spoon, a metal spoon and a pencil.

Conductivity experiment with metal

Conduction is a known property of the metal.

Metals are excellent conductors of heat and electricity: thermal energy and electrons pass through them very quickly.

You can experiment with the conductivity of heat and electricity by using objects from around the house.

(Adult supervision recommended.)

Gather a metal spoon, wooden spoon, and other kitchen utensils to makecompare thermal conductivity.

Put them in a glass jar with hot, but not boiling water, which one heats up faster?

The ends of metal utensils should be hot first because they conduct heat better.

For a little more excitement, try this activity again, using only metal utensils with some cold butter on top of each plate.

Which one loses the butter first? Because that’s how it is?

Look at the thickness and length of each pan’s handles, as well as the top surface (for example, a wire whisk has a butter heating surface smaller than a ladle) for clues.

Also remember that some metals conduct heat better than others.

Test the object for electrical conductivity

What you need:

  • Type C or D battery
  • Aluminium sheet
  • Flashlight or other 1.5 or 3V bulb

What you are doing:

1. Fai un lungo nastro dalla lamina, tagliandone un pezzo di circa 18 "x 2". Fold the foil lengthwise in quarters to form a ribbon. Tieni o fissa un’estremità di questo filo con del Scotch tape all’estremità piatta (terminale negativo) di la batteria e avvolgere saldamente l’altra estremità attorno ai lati "filettati" (vite) della lampadina.

2. You are now ready to test various objects around your home to see if they conduct electricity. To do this, press the positive pole of the battery (the bulge end) on one side of the object and the metal end of the bulb on the other side creates a series circuit: the electric current is free to flow through the wires from battery to bulb to battery.

What are the variables that can prevent a light bulb from shining, even if the object it touched was metal? While the object can be metal and can also be a very good conductor of electricity, the plastic or paint coating can break the circuit connection.

Security Notice: Remember never to insert wires or other objects into electrical outlets! However, the electricity generated by the battery for this experiment is in a safe amount.

Play copper plating

Try this experiment: clean your pennies first, then watch it oxidize and use it to cover (ora plate) iron nail with copper! Although the newer pennies contain only a small amount of copper (2.5%), they still have enough for this project.

What you need:

  • Ceramic or plastic bowl
  • Vinegar
  • salt
  • cents
  • Paper towels
  • Non galvanized iron nail

1.Napełnij dno miski octem, wymieszaj łyżeczkę soli, a następnie wrzuć 10-15 matowych pensów. Odstaw na pięć minut, a następnie wyjmij i połóż na ręczniku papierowym do wyschnięcia.(Don’t dump out the vinegar and salt yet, though!) The pennies will be much shinier than before; this is because vinegar is an acid that ‘eats’ away the oxide layer on the penny that is making it dull. However, if you don’t rinse or dry the clean pennies, after a while you should see a blue layer appear on them. Jest to związek tlenku miedzi spowodowany wzajemną reakcją miedzi i tlenu; vinegar (acetic acid) and salt favor the reaction of oxygen with copper.

2. Now hammer a non-galvanized iron nail into the vinegar solution. If you look closely you will see small bubbles on the sides of the nail. Leave for 30 minutes, then check for a dark brown copper layer. As? The vinegar solution contains copper from the penny it has cleaned. When the solution reacts with the nail, a chemical exchange takes place which leaves a copper coating on the nail. When you pull the nail out of the solution, the copper will be a one. little sticky; you can put it on a paper towel to dry it. The nail may not be fully covered but there will be enough copper to see it.

You can try this experiment again using only coins made before 1982 (made up of 95% copper).

Was the nail coated with copper faster or at the same time?

Which material is best for conducting heat, wood, plastic or metal? In this experiment, we learn how to conduct heat and how different materials conduct heat differently.

Note: Although the materials for this experiment are easy to find, one of them is boiling water. Depending on the age of the children, adult assistance is important. Watch our how-to video and printable instructions below.

How a scientific experiment works

Heat can move in three ways: conduction, convection and radiation. In this experiment, heat was transferred by conduction.

Conductionis the transfer of heat from one particle of matter to another without the movement of the matter itself. When the matter is heated, the particles that compose it begin to move faster.

In this experiment, when we put the spoons into boiling water, the fast-moving water particles collide with the slow-moving particles of the spoon. When the water particles collide with the spoon particles, the spoon particles start moving faster and the metal spoon gets hotter. the spoon heats up, the butter begins to melt and the pearl slides down the spoon.

Why did the bead slide down the metal spoon faster than it did on the wooden or plastic spoon? Metal is good conductorheat and wood and plastic are goodinsulators.A conductor transfers thermal energy (heat) well, while an insulator does not transfer thermal energy (heat) well.

Hope you enjoyed your experiment, here are some printing instructions:

How to do a simple heat conduction experiment

introduction

We have seen previously that the main methods of heat transfer are conduction, convection and irradiation. Although these topics have been covered individually, it is not uncommon for all three methods to work at the same time.

Thermal cylinder

Butelka termosu jest doskonałym przykładem pokazującym, jak hamowane są wszystkie trzy metody. Butelka termosu ma podwójną ściankę, która tworzy próżnię, i błyszczącą powierzchnię wewnątrz. We’ve seen that the shiny part on the inside is an example of radiation, where heat is reflected back from the walls and back to the liquid. Heat conduction is inhibited by the use of insulators such as glass and plastic. Ciepło ucieka przez ciało i pokrywę, ale bardzo powoli. Próżnia hamuje prądy konwekcyjne, a także przewodzenie.

Cooking food

How to do a simple heat conduction experiment

Grilling, roasting and grilling over an open fire when camping are examples of cooking by radiation, however, when grilling and placing food on the racks, conductivity also comes into play When the air gets hot, currents form of convection between air and food.

When baking a cake or roasting in a pan, all three methods come into play again. When the oven air heats up, convection currents occur. The pan that holds the food becomes hot by conduction. oven walls get hot due to conduction. radiation.

We have seen previously that when cooking or steaming, air and water are heated by convection, but solid food is heated by conductivity as the atoms contained in it begin to collide with each other.

In addition to cooking, there are simple heat transfer experiments you can do at home.

A A simple heat conduction experiment

Zdobądź przedmioty z różnych materiałów. Najlepiej byłoby, gdyby miały tę samą geometrię, na przykład pręty wykonane z drewna, szkła, aluminium i żelaza. Wystarczą jednak materiały, takie jak plastikowe, drewniane i metalowe sztućce. You will also need a heat source such as hot water, a stove burner, a hot a plate, or a candle. Aby dokonać pomiarów, użyj zegarka lub innego urządzenia do pomiaru czasu oraz prostego thermometeru. Aby zapisać swoje wyniki, użyj arkusza kalkulacyjnego lub papieru milimetrowego.

Per la misurazione diretta, utilizzare Scotch tape o nastro isolante per attaccare il thermometero all’oggetto Immergerlo parzialmente in water calda e misurare tempo e temperatura ogni pochi secondi Disegnare un grafico della temperatura rispetto al tempo con temperatura variabile dipendente dall’asse y e variabile tempo indipendente su l’asse x. Do this for each subject. Compare your scores.

For indirect measurements, melt a substance on the object, such as candle wax or paraffin. Slowly heat the object and take note of the time it takes to dissolve the substance. If you’re careful, the substance can also be ice, butter, or something similar. In this case, the support should be a spoon.

Be sure to exercise caution when conducting heat transfer experiments as the structures and sources will be hot.

In the next section, we’ll look at some simple experiments you can do with convection and radiation.

How to conduct the experiment:

  1. Oznacz słoiki temperaturami, których zamierzasz użyć w eksperymencie. We used room temperature water , hot water , and cold water .
    How to do a simple heat conduction experiment
  2. Włącz kran zlewu i zmierz temperaturę. Wyreguluj kran tak, aby temperatura wynosiła około 72°F. Napełnij słoik oznaczony Temperatura pokojowa. Alternatively, you can fill a jar will cool tap water and let it sit out for day. The water will eventually become the same temperature as the room.
  3. Fill the jar labeled Cold Water 3/4 of the way with cold tap water. Add ice to the jar to cool the water even farther.Remove the ice from the jar before the experiment is complete.
  4. Osoba dorosła powinna pomóc przy dzbanku z gorącą wodą. Odkręć kran tak gorący, jak to możliwe. Fill the jar labeled Hot Water with hot water. An adult could also heat up some water on the stove. Tylko uważaj, aby nie było za gorąco.
  5. Add a drop of food coloring to each of the jars and observe what happens over time.

How to do a simple heat conduction experiment

Questions to ask:

  • What happens to the drop of food coloring?
  • Does the food coloring behave the same in each of the jars? Why or why not?
  • What is the difference between the jars?
  • What can you say about the relationship between heat and molecular motion?

How to do a simple heat conduction experiment

The science behind it

Cząsteczki poruszają się szybciej, gdy są cieplejsze i wolniej, gdy są zimniejsze. The drop of food coloring spreads out fastest in the hot water because the molecules are moving the fastest of the three jars. The food coloring spreads out fairly quickly in room temperature water and slowest in the cold water. Eventually the food coloring spreads throughout all three jars.
