5 OUTPUT~ Write It! Station Directions: Before completing this station, please make sure you have already completed the INPUT stations. Answer each of the task card questions on the lab sheet in the Write It! Section using complete sentences.

6 OUTPUT~ Assess It! Station Directions: Before completing this station, please make sure you have already completed the INPUT stations. THIS IS YOUR CLASSWORK GRADE FOR THE TASK! Answer all questions from the task cards on the lab sheet by filling in the bubbles in the ASSESS IT! Section Alternate Plans: SOC code

7 OUTPUT~ Illustrate It! Station Directions: Before completing this station, please make sure you have already completed the INPUT stations. Each member of the group will draw a quick sketch on the lab sheet in the Illustrate It! section that shows they understand the concept that is being taught. Use the colored pencils and markers that are provided. The directions for the sketch are provided on the task card at the table.

8 OUTPUT~ Organize It! Station Directions: Before completing this station, please make sure you have already completed the INPUT stations. Each group will organize the cards. Each of the cards will be used. Once you think you have correctly organized the cards you MUST SHOW THEM to the teacher in order to get your lab sheet signed off in the Organize It! Station. Please mix up the cards before leaving this station.

9 Read It! Plasma Basics Plasmas are a lot like gases, but the atoms are different, because they are made up of free electrons and ions of an element such as neon (Ne). You don't find naturally occurring plasmas too often when you walk around. They aren't things that happen regularly on Earth. If you have ever heard of the Northern Lights or ball lightning, you might know that those are types of plasmas. It takes a very special environment to keep plasmas going. They are different and unique from the other states of matter. Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles. In neon gas, the electrons are all bound to the nucleus. In neon plasma, the electrons are free to move around the system. Finding a Plasma While natural plasmas aren't found around you that often, man-made plasmas are everywhere. Think about fluorescent light bulbs. They are not like regular light bulbs. Inside the long tube is a gas. Electricity flows through the tube when the light is turned on. The electricity acts as an energy source and charges up the gas. This charging and exciting of the atoms creates glowing plasma inside the bulb. The electricity helps to strip the gas molecules of their electrons. Another example of plasma is a neon sign. Just like a fluorescent lights, neon signs are glass tubes filled with gas. When the light is turned on, the electricity flows through the tube. The electricity charges the gas and creates plasma inside of the tube. The plasma glows a special color depending on what kind of gas is inside. Inert gases are usually used in signs to create different colors. Noble gases such as helium (He), Neon (Ne), Argon (Ar), and Xenon (Xe) are all used in signs. You also see plasma when you look at stars. Stars are big balls of gases at really high temperatures. The high temperatures charge up the atoms and create plasma. Stars are a good example of how the temperature of plasmas can be very different. Fluorescent lights are cold compared to really hot stars. However, they are still both forms of plasma, even with the different physical characteristics.
