  1. Cloning is very interesting because when someone dies you can make a clone of them from cells! The first ever animal cloned was named dolly the sheep. 50 mice can be cloned from one mouse! In order to clone you first have to isolate the donar cells,then you have to remove the nucleus from the egg cell,then you stimulate the cell nucleus,then you implant the embryo.

  2. A laser is a device that generates and intense beam of coherent. Lasers are used in CD players to dental drills to high-speed metal cutting machines. Also the laser medium can be a solid, gas, and liquid or semiconductor. Most laser lights are different from other normal light. Another key to a laser
    is a pair of MIRRORS, on one side of each end of the lasing medium. Also laser lights contain on
    specific wavelength of light (one specific color).

  3. GMOs are genetically modified organisms. They have great benefits but also have problems. They decrease the price of food and expand their life. But when planted the weeds near the seed become stronger and harder to kill. This causes farmers to use stronger pesticides which can poison the plant. They also affect farmers because there organic plants can become tainted with GMOs which have patents, that can get the farmer sued.

  4. S.C.U.B.A means Self Contained Underwater Breathing Apparatus. It was a life changing invention. Scuba help people explore the oceans for long periods of time. Scuba was invented from Jack Cousteau. The device was originally used for the military in World War l to disable underwater bombs.

  5. clones are a exact copies of a person or animal. but clones don’t have the same personalities. and many problems with cloning.

  6. Cloning are copies of something. Some animals are being cloned like sheep, deer, and coyotes.Medical cloning is what could able to cure caners .To be a better parent human clone can improve the parents relationship

  7. Clones are exact copies of the subject cloned. In 1996 Dolly the sheep was cloned. Cloning still has many problems for one, clones age rapidly. Cloning takes place when you take DNA from one cell and place it into another cell. Clones are still being researched today.

  8. Cloning can expand human and animal populations. Cloning can be used to make a exacted replica of a human or animal body. Cloning can be used to make two of the exact beings. People might be able to cure cancer. Cloning can be used by a scientist and make another animal that they find to experiment.

  9. The microscope is one of the most helpful invention. It is used to view the smallest of objects through a lens that blows them up. Those small objects are called microscopic. that means it’s smaller than smaller. The microscope is also used to see bad organisms for men. It is very cool to have this wonderful invention.

  10. If I was in this project I would chose to do underwater robotics because I like water and robotics.I am in 5th grade and I would like to wish you guys good luck because 7th grade is the first junior high and I heard it is pretty hard.
