School laboratory

1. Far-near

The aim of experiment: Put up, how the sun influence on the temperature.

Materials: 2 thermometers, lamp, long ruler.

Process: take the ruler and put one thermometer on the mark 10 sm, the second thermometer-on the mark 100 sm. Put the lamp near the initial mark. Turn on it. Write the temperature after 10 minutes. Results:

Near thermometer show bigger temperature.

Why? Thermometer, which dispose near the lamp, get more energy, is warmed up more. Light from the lamp is dispersed and they can't warm the distant thermometer. we can see it with planets. Mercury- the nearest planet to Sun- get more energy. More distansed planets get less energy and their atmosphere themperature render another factors.

2. Chemical warm

The aim of experiment: Show, that chemical reactions can give warm.

Materials: Thermometer, can with lid, bast whisp, vinegar, glass.

Process: Put thermometer in the can and close the lid. After 5 min write temprature. Put the bastwhisp in the vinegar (1-2 min). Shake off the vinegars' drops and put thermometer in the bust whisp. Put the bust whisp with thermometer in the can and close the lid. Write the temperature (5 min).

Sums: Temperature is growing.

Why? Vinegar dissolve the covering on the steel and the steal is oxidized. The warm is emphasized.

3.Radiation

The aim of experiment: Put up, how the colour influence on the radiation shallowing up by objects.

Materials: black paper, two thermometers, stepler, aluminium foil, lamp, ruler.

Process: Put the packet from the black paper, fasten it with stepler and put there thermometer. Put the second thermometer on the foil and make the packet. Write the temperature. Put the packets side by side and put near(20 sm) the lamp. Turn it on (10 min), regular compare the temperature.

Results:Thermometer shows us more higher temperature.

Why? Black colour shallow up lights. Object look like black, because it's don't repel light on the eyes. Shallowing up the lights bring to the growing up of temperature. Foil shallow up lights bader. Thats why the temperature is lower. [10]
