In this science experiment, we will determine whether combining long and short wavelength colours would balance the average temperature. To perform this experiment, we investigated how different colors of paint on houses can affect their interior and exterior temperatures, as well as their insulation rates. We tested houses painted with solid colors (such as red, blue, green, and orange) and combination colors (like red/blue and green/orange).
The combination colors were chosen to explore the effects of mixing long wavelength colors with short wavelength colors. Our main objective was to determine whether these combinations could achieve a balance in terms of average temperatures and insulation rates compared to the solid color counterparts.
In simpler terms, we wanted to see if certain paint colors could help maintain a more moderate temperature inside and outside the houses, and if combining specific colors could enhance their insulating properties.
To determine the difference between the insulation rate of houses painted with combination (long and short wavelength) colours and solid colours.
1. In the experiment, we will determine the insulation rate of houses painted with both combination and solid colours.
2. Combination colours are red-blue and green-orange.
3. Solid Colors are red, blue, green, and orange.
4. We combined the colours to test the long wavelength of colours with short-wavelength colours.
1. Oil paints
2. Foam Boards Houses
3. White Paint
Step 1: Take two foam board houses.
Step 2: Paint these houses with oil paints.
Step 3: Take a third foam board house and paint it with white colour.
Step 4: The third house will act as the controller.
Step 5: Place these houses outside your home.
Step 6: Measure the temperature of the three foamboard houses throughout the day using a digital thermometer.
Step 7: Record your observations.
1. We found that the order of lowest to highest interior temperature was the same as the longest to the highest wavelength of colour.
2. The houses that were painted with combination colours fell in between the solid counterparts.
3. The house that was painted with green and orange colour attained the highest temperature. After this came the red, red-blue, green, blue, orange, and the last one was control.
4. The house that had the highest insulation rate was blue-coloured. After this came the green, green-orange, red-blue, red, orange, and the last one was control.
1. The house’s interior temperature, when painted with the combination colour red-blue, was the highest.
2. The average of blue and red colour wavelengths defined the interior and exterior temperature of the house.
3. But in a green-orange house, we did not obtain a consistent result. The interior temperature of the house almost matched the orange colour house. On the other hand, the exterior of the house was warmer than each solid colour.
4. The difference in wavelength between green-orange houses was more than the difference between the wavelength of red-blue houses.
5. The insulating rate of houses was better in the blue-coloured houses.
6. The average tendency was better when the distance between the wavelengths increased.
7. As the wavelength increases, the insulating rate decreases.
8. The insulation rate of the house that was painted with the combination colour was maintained throughout the day.
1. Take help in creating foam houses.
2. Paint the foam houses thoroughly.
In this experiment, we determined the insulating rate of various houses along with their interior and exterior temperatures.
Q.1 What was the aim of your experiment?
ANS. We aimed to determine the interior and exterior temperature of houses painted with combined colour and also their insulation rate difference.
Q.2 Which house attained the highest temperature?
ANS. When painted with red-blue colour, the interior of the house was the warmest.
Q.3 What is the relation between average tendency and distance between wavelengths?
ANS. When the distance between the wavelength increases, the average tendency also increases.
Q.4 What is the relation between insulating rate and wavelength?
ANS. The insulation rate decreases with increasing wavelength.
