Rather than logos, have participants use a famous tag line or marketing slogan. Break the group into small teams of four to six members. Have the team choose a logo that best represents them. Alternatively, choose a logo that best represents the project or the whole work group they belong to.
Your body makes vitamin D when your skin is exposed to the ultraviolet B (UVB) rays in sunlight. About 5 to 30 minutes of exposure to the skin on your face, arms, back or legs (without sunscreen) two times every week is enough. But, too much exposure to sunlight is a risk for skin cancer, so you should use sunscreen after a few minutes in the sun, even on hazy or cloudy days.
Most of the world's population live in areas with insolation levels of 150-300 watts/mÂ², or 3.5-7.0 kWh/mÂ² per day. Solar radiation is absorbed by the Earth's land surface, oceans â which cover about 71% of the globe â and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection.
