__**Our first Experiment: Green heating 3**__

**// Green heating 3 //**
 * Aim: ** To see what colours absorb the most the most heat and also which is most efficient in the use of solar panels.
 * Hypothesis: **We think that the darker colors are going to be more efficient.
 * Method: **
 * Ø ****Face solar panel towards sun and attach to voltmeter. **
 * Ø ****Take reading after two minutes for solar panel when it has no color filter on it. **
 * Ø ****Apply a color filter and take the reading after two minutes. **
 * Ø ****Do the same for all the other colours you are testing. **


 * Equipment: **
 * Ø ****Solar panel **
 * Ø ****Volt meter **
 * Ø ****Coloured filters **
 * Ø ****Wires **

Ø <span style="font-family: 'Cambria','serif'; font-size: 13pt; line-height: 115%;">Measure the temperature of the water without a cover. Ø <span style="font-family: 'Cambria','serif'; font-size: 13pt; line-height: 115%;">Cover the beaker with tin foil/black paper/plain paper and then record the temperature.

**// Green heating 5 //**

** Aim: ** to see if infrared radiation is a form of electromagnetic radiation, like light, then surfaces which reflect light will reflect infrared radiation, and surfaces which absorb light will infrared radiation. = Method: = Ø Put water in small beaker attached to solar boiler. Ø Angle the solar boiler so that the focus of light is concentrated on the beaker at the end of the metal rod on the solar boiler. Ø When water boils take pictures for evidence. Ø As a backup experiment put a leaf in the concentrated ray of light and let it burn. Ø Take a picture of that experiment for evidence. = Equipment: = Ø Solar Boiler Ø Water Ø Camera Ø Dry Leaf =** Results ** : = In this experiment we found that infrared radiation can heat when concentrated
 * Hypothesis: ** We think that the experiment will prove that infrared can heat when concentrated.
