Thisradiation experiments at homeis super easy and doable for any homeschooling family.
I just love making science click and help kids discover the exciement of experimenting like thisradiation heat transfer experiment.
We can tell the temperature of the oven is a lot higher than the temperature of the room.
We know we can feel heat, but what is heat?
This simpleradiation experiments at homewill allow you to explore radiation and conduction with kids of all ages!
Heatis a punch in of energy that can be transferred from one object to another.
A warmer object will transfer its heat energy to a colder object and raise that objects temperature.
Heat can be transferred to objects in several different ways.
One way is by radiation, and another is by conduction.
Whether you are a parent, teacher or homeschooler you will love thisradiation experiments for schoolor at home!
The sun can raise the temperature of your skin and body without even touching you.
It transfers its heat energy to your skin by radiation.Radiationis the transfer of heat by electromagnetic waves.
We cant see these wave, but we know they exist.
We can feel the results.
Transferring Heat By Conduction
Have you ever walked on a sidewalk in the summertime in bare feet?
Did the concrete feel warm?
The sun transferred its heat to the sidewalk via radiation and caused the temperature of the concrete to rise.
This is called conduction.Conductionis the transfer of energy from one object to another through direct contact.
Radiation science experiments
Lets do a simple experiment to demonstrate how radiation and conduction works.
Hold the piece of bread in your hand.
Notice the temperature and appearance of the bread.
Next, place the bread in the toaster, then start the toaster.
Look inside the toaster..
Conduction convection radiation experiments
Do you see the red wires?
The wires are red because electricity is flowing through them and heating them up.
Never touch these wires.
The electrical charge is so great you could get electrocuted.
Without touching the toaster, feel the air around the toaster?
What do you notice about it?
The heat is radiating from the hot wires and increasing the temperature in the air and object around them.
Notice the temperature of the bread.
Is is different than when you placed the bread into the toaster?
Look at the appearance of the bread.
Is the color or texture different than before it was toasted?
The heat radiating from the wires transferred to the bread.
We can see this by the color and texture change.
The bread turned from white to brown and from soft to crispy.
Notice what happens to the butter.
It should be melting.
The toast is warmer than the butter, so it transfers its heat to the butter.
This warms the butter past its melting point.
This transfer of heat from the toast to the butter is conduction.
I love simple science experiments and projects that demonstrate seemingly complicated concepts.
Try this easy experiment at home to explain how heat is transferred to your kids.
