The Trackster is designed to find people trapped in damaged buildings after an earthquake or an explosion. It enables the rescue team to search for victims from a safe distance. The Trackster consists of a small body with four tracks. It is operated by a hand-held control panel. This sends a radio signal to the robot. The trickster runs on an electric motor which is powered by a ten-volt portable battery. A video camera is attached to the front of the robot – this allows the rescue team to see if there is anyone in the building.

Hanna and Heather Craig, twin sisters aged seventeen from Alaska, have invented a new winter rescue device: a 1.2 metre-long robot called the Ice Crawler. The robot is designed to take a rope to a person in a dangerous situation, for example, on thin ice or very soft snow.
The robot runs on two 12-volt drive motors – one on each of the tracks. These are powered by a 12-volt battery. A plastic tube carries the control panel’s wiring. It also holds the rope that pulls the victim back to safety. A video camera is attached to the front of the robot. This helps the rescue team to see where the Ice Crawler is going in snowy conditions or on very rough ground.

Ryan Patterson has designed a glove that can translate sign language into text. It uses electronic sensors to read the hand movements of the person who is wearing it. Then it transmits the data to a portable device that displays the text on screen. The device only translates the alphabet, but a special program allows the user to adopt hand movements.
Ryan has built two prototypes using a leather golf glove. He has tested it with students from the National Technical Institute for Deaf (NTID). He has a patent on the device, which means that he owns the idea.

Hanna and Heather Craig from Alaska have invented a new winter rescue device: a 1.2 metre-long robot called the Ice Crawler. The robot is designed to take a rope to a person in a dangerous situation, for example, on thin ice or very soft snow.
 The Ice Crawler’s body consists of two tracks made of silicon-reinforced rubber, which is very strong and flexible even at extremely cold temperatures. This means the robot can move over ice, snow or rough ground without getting stuck. The Ice Crawler is operated by a control panel. This allows the rescue team to stay at a safe distance from the victim. The control panel enables the user to steer the robot, move it forwards and backwards, and switch the power on and off. A plastic tube holds the rope that pulls the victim back to safety.

Our solar system is over 4,500 million years old. In a solar system, the sun and the planets form at the same time. They form from a cloud of gases called nebula. A nebula rotates in space and the force of gravity pulls material to its centre. The nebula contracts and its centre gets hot. This hot centre becomes a star.
The outer part of the nebula is not so hot. When the temperature goes down the gases condense into particles of dust. The dust slowly sticks together and forms the planets. Life on our planet begins from the dust of a dying star.
