I would like an experiment to show that dark bodies emit heat faster than brightly coloured bodies?

Get two plastic bottles and paint one black and the other white.  Put one of those liquid crystal temperature strips on each one to easily monitor the temperature and fill them each with boiling water.  Screw on the lids and you should see that the black painted bottle cools down faster than the white one.

You could focus sunlight from a bundle of light fibers using a lens and really burn things up.\n\nFocused sunlight can burn holes through steel plates.\n\nAny amount of sunlight falling on something will heat it.\n\nYou only need a simple thermometer to check it out.

the human body gives off the same amount of heat as a 75watt light bulb.

dark colored clothes absorb more heat than light colored ones. if you are wearing dark colored shirt, chances are you will feel warmer.

false - temperature is a measure of heat

I would say that it is made up of hot low-density gas.  The assumption in the question is that there are no dark spectral lines.  That means that there is no "black body" radiation being transmitted through a cooler gas.  A hot, dense gas with strong molecular interaction would tend toward a more continuous spectrum; without dark lines there isn't a cooler gas surrounding it.

As heat increases, great amounts of energy are released in photons- Thus, the photons have greater energy at higher heats..makes sense, right?  So, higher energy photons are those with shorter wavelengths, like for example, the color red has a longer wavelength than the color blue-and blue is a higher energy photon.  You can actually measure the temperature of materials by measuring the light emitted from them, if you know the material.

Gamma rays, heat and, in the case of a few highly-radioactive elements, light; they glow in the dark.  Beta particles which are high-energy electrons.   Their kinetic energy can be converted into light by a phosphor such as zinc sulphide, or if they enter a transparent medium with a high refractive index, they emit blue Cerenkov radiation.  Radioactive materials are warmer than their surroundings because alpha particles, beta rays and neutrons are all fast-moving particles and when they are absorbed their kinetic energy is converted into heat.  In a nuclear reactor the heat is used to raise steam which drives a turbine.  In the thermionic generators used on deep space probes it is converted directly into about 200 watts or so of electricity.

Here are some experiments.

Define HDT in your experiment.  Are you looking at a heat history shift?

I've seen somebody got about 400 ºC using little pieces of mirrors over a parabolic structure. Sun light was concentrated in one point

luminous flame can be seen, gives off light,nonluminous you can not see, usally from a very high heat source

All natural light sources generate a "spectrum" of frequencies that approaches the "black body" radiation curve. The peak of that curve denotes the temperature of the emitting object. Certain frequencies can be affected in transit via interaction with materials as in emission and reflection nebula (ie. various places within the Orion constellation). The sun emits UV radiation commensurate with its black body ideal.\n\nUNLESS someone can show that the moon absorbes ALL UV frequencies on reflection then by definition:\n\nMOONLIGHT DOES INDEED CONTAIN UV FREQUENCIES\n\n===============================================\nSome of you people amaze me, you answer questions that you know NOTHING about. Answers like "No because it is reflected light" are a case in point. Is your blue shirt invisible in the mirror because the light coming from your shirt is lost as it reflects off of the mirror. I THINK NOT! Reflected light IS LIGHT. Some of it is absorbed, reflected, refracted but it is light. YES; the UV portion in moonlight is very weak, hey guess what -ALL THE LIGHT frequencies in moonlight are weak; THATS WHY MOONLIGHT IS DIM.\n==============================\nUV is NOT produced only from objects above 24000 degrees. It is produced at ALL temperatures, but the lower the temperature the lower the amount of UV that is produced. PLEASE Google "black body radiation"

It can because a dark color will absorb more heat or radiation causing them to melt faster, say in a black glass vs. a clear one.

Try the sonometer or the resonance experiment

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask.  It is done by using the principles of the kinetic theory of matter.  \nAnother cool project might be doing something with dry ice.  Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions.  Make some dye molecules or something.\n\nHope one of these ideas works for you.

Burn it in a sprectrophotometer.  Look at the emitted light.
