Electric Light

Today in class we attempted to light a bulb using only a battery, wire, and bulb. This can be done by connecting the wire to one end of the battery and connecting the other end of the wire to the bulb, when you touch the bulb to the other end of the battery the bulb will light up. The reason for this is the energy from the battery is allowed to flow through the wire into the bulb and when the bulb is connected to the opposite charge light is created.

Mu Friction

Friction occurs every time two objects come into contact. Friction is the reason why a soccer ball wont keep rolling on forever. Friction technology is also used in shoes to complete different tasks. For example soccer cleats are made to create friction in grass to better play soccer. Where as hiking shoes are made with materials to create friction to better climb.

Another Planet


My planet name is Detis. This planet is twice the size of earth and can also maintain human life. Planet Detis is different from earth because of its size and weight. It is also different from earth because of its gravitational pull which would be double that of earth because it is double the size. Although the pull of gravity on your body would be proportional.
