We go on with the first cycle students work plan dedicated to body awareness and healthy habits. So this friday we are going to organize like every year a healthy breakfast.. These children often do not make a healthy breakfast for several reasons: no time, no chance, or have no knowledge.

The high jump is an athletics event where competitors must jump over a bar at measured heights.
In modern high jump, a fibreglass or aluminium bar (other materials allowed, but weight and sag parameters are controlled by rules) of approximately 4 metres in length (IAAF rules control length for record purposes, which see), with a round (or triangular or square) cross-section for most of its length but with two square resting points at each end, is placed at a measured height on two "uprights" which allow the bar to rest on its ends at a measured height; cleared heights are reported by measuring the altitude of the top of lowest part of the bar). Directly behind the bar is a soft foam mat (or any other safe landing material) that allows a comfortable and safe landing. Competitors run up (standing start is allowed) to the bar and must leap, off one foot, and clear the bar. They may touch the bar in their clearance, but if the bar falls due to their touch then the jump is unsuccessful.
Historically, a variety of techiques have been used by competitors to clear the bar, but since its popularized exhibition (very well may have been used earlier) in the 1968 Olympics, Dick Fosbury won a gold medal in the high jump. His method was to sprint diagonally towards the bar, then curve and leap backwards over the bar. This method was then called the Fosbury Flop and has been almost universal amongst elite competitors, though dive straddle biomechanically competes favorably with the flop depending on body structures and other factors.
In a competition, the bar is intially set at a low height, and is only moved upwards in set increments (usually 3 or 5 centimetres). Each competitor has the option of choosing what height they wish to start at, but once a height has been cleared by one competitor obviously a competitor cannot choose to start at a lower height. Once a competitor has elected to start jumping, they can choose whether to attempt subsequent heights, but if they choose not to attempt a height it counts as a "pass". Any competitor who records three consecutive misses is out of the competition. The competitor who clears the highest jump is declared the winner. If two or more competitors clear the same maximum height, the competitor with the lowest number of failed attempts at that height is declared the winner, and if that fails to separate the competitors the next lower height's failures are considered, and so on. If all that fails to break a tie for first place, then a jump off is conducted; heights obtained in such a jump off are eligible for records. IAAF rules are nearly universally the model used for sport high jumping.
The men's world record height is held by Javier Sotomayor of Cuba at 2.45 metres, whilst the current women's world record is 2.09 metres held by Stefka Kostadinova of Bulgaria.

The long jump (formerly called broad jump) is an athletic (track and field) event in which athletes attempt to land as far from their take-off points as possible.
Competitors sprint down a runway (at elite level, usually coated with the same rubberised surface as running tracks), jump as far as they can off a slightly raised wooden board into a pit filled with fine gravel or sand.
The minimum distance from the board to the indentation made by the competitor in the gravel is measured. If the competitor starts their leap with any part of their foot in front of the board (a layer of plasticine called “toeboard” is placed immediately in front of the board to detect this occurrence) the jump is declared illegal and no distance is recorded.
The exact format of the competition varies, but generally each competitor will get a number of attempts to make their longest jump, and only their longest legal jump counts towards the results. The competitor with the longest legal jump at the end of competition is declared the winner.
Speed in the run up and a high leap off the board are the fundamentals of success at the discipline, and it is unsurprising that many sprinters, notably including Carl Lewis, also compete successfully in the long jump.
The long jump has been part of Olympic competition since the inception of the Games.
The long jump is also notable for one of the longest-standing world records in any track and field event, with Bob Beamon leaping 8.90 metres at the 1968 Mexico City Olympics, a jump not exceeded until 1991. On August 30 of that year Mike Powell of the USA leapt 8.95 metres in Tokyo. The current world record for women is held by Galina Chistyakova of the former Soviet Union who leapt 7.52 metres in Leningrad in 1988.
