The Countdown BeginsThe classic Concentration memory game. The cards begin face down. Click one to turn it over. Try to find the second card that matches the first. If the second does not match, click a third card to look for a new match. Your previous selections return to a face down position. If they do match, the cards are removed to reveal part of the background rebus. Try to determine the rebus message in as few number of turns as possible.
Focus on Safety
Ice in a cloud appears to be a key element in the development of lightning. Storms that fail to produce quantities of ice may also fail to produce lightning. Positively charged ice crystals rise to the top of the thunderstorm, and negatively charged ice particles and hailstones drop to the middle and lower parts of the storm producing enormous charge differences.
Outdoors is the most dangerous place to be during a lightning storm. If you can hear thunder, you are close enough to be struck by lightning. Go indoors or get into a hard-topped vehicle. Visit JetStream - An Online School for Weather for more info.
