Science Discovery

2/20/15

My science discovery today is about how computers work. The computer does most of its work in a part of the machine we cannot notice. It has a control system that converts data intake to information output. This control center, called the central processing unit, is a very complicated system. The CPU holds an extensive set of circuitry that gets rid of stored program instructions.

This next science discovery is on jellyfish. Jellyfish live in the sea and are located in every oceans, and sometimes they are found in other fresh waters. Jellyfish's tentacles are used to sting their predators from attacking them. They're mostly made of water and they do not have brains.
