The goaltender, or goalie, in ice hockey is a player who defends the goal net from shots. He plays in the area in front of the net called the goal crease. Due to the power and frequency of shots, the goaltender wears special equipment designed to protect the body from direct impact.

The goaltender has special privileges that other players do not. His equipment is not subject to the same regulations. He may legally hold the puck with his hands to cause a stoppage of play. If a player from the other team hits him without making an attempt to get out of his way, the offending player is penalized.

Goaltending equipment

Most modern goaltending equipment is made from the same basic materials: hydrophobic synthetic leather and nylon on the outside; dense closed-cell foams and plastics inside.

The National Hockey League and most other leagues specify maximum dimensions of goaltending equipment to prevent goalies from having an unfair advantage[1].

Blocker

The blocker is worn on the hand that holds the stick. It consists of a glove with a rectangular board attached to the backhand side.

Chest and arm protector

The chest and arm protector (often referred to as the C/A) is designed to protect the chest and arms from the impact of pucks. It is worn under the hockey sweater.

Jock

A goal jock, which protects the pelvic area, is more protective than a common jockstrap. In addition to housing a standard protective cup, the jock is padded to spread an impact over a larger area.

Instead of a jock, female goalies wear a pelvic protector called a jill.

Leg pads

Goalies wear special leg pads that descend from cricket pads. The pads are typically 10 to 12 inches (25–30 cm) wide and extend 4 to 8 inches (10–20 cm) above the knee.

Mask

The first commonly used goalie masks were solid fiberglass with holes for the eyes, noses, mouth, and for ventilation. Today, most goalies don masks made of fiberglass, kevlar, carbon fiber, and other composite materials. Modern masks have a large cutout in the eye and nose area covered by a steel or titanium cage.

An alternative to the mask is the helmet and cage combo, which consists of a wire facemask attached to a standard hockey helmet.

Pants

Goalies' protective short pants are similar to the pants forwards and defensemen wear. They have heavy padding in the thigh area with lighter padding in the back and sides covering the back of the thighs, tailbone, buttocks, and waist.

Skates

Goal skates differ from regular hockey skates. The blade is longer, wider, and flatter to provide the goalie with more stability. It is made out of carbon steel rather than stainless steel. The blade is shorter vertically so that the goaltender is lower to the ice. The boot does not have a tendon guard, which is the piece of a regular hockey skate that extends up the back of the ankle to protect the Achilles' tendon. Finally, the boot is inside a plasic cowling to protect the foot from direct impact.

Stick

The special hockey stick goaltenders use has a blade that is approximately 3½ inches (8.9 cm) wide. The lower 25 to 28 inches (63.5–71 cm) of the shaft is widened to provide more blocking surface. This area is called the paddle. Although traditional goalie sticks were usually made completely of wood, most modern sticks are reinforced with graphite and fiberglass and the paddle and blade are injected with foam to make them lighter. Recently, manufacturers have begun to produce sticks made completely from composite materials, which are more durable.

Trapper

The trapper, catcher, or catch glove is the glove worn on the free hand. It is similar to a baseball mitt, but it is much more protective and has a deeper pocket.

Science kits, science lessons, science toys, maths toys, hobby kits, science games and books - these are some of many products that can help give your kid an edge in their science fair projects, and develop a tremendous interest in the study of science. When shopping for a science kit or other supplies, make sure that you carefully review the features and quality of the products. Compare prices by going to several online stores. Read product reviews online or refer to magazines.

Start by looking for your science kit review or science toy review. Compare prices but remember, Price $ is not everything. Quality does matter.
