ESSC 202 Lab Presentation - October 29, 2007 Listen for Lightening – A Severe Weather Lesson Plan for 2 nd Graders Engage: The purpose of this experiment is to teach kids how lightning forms and to demonstrate how the buildup of static electricity can actually generate small pops or sparks of lightning. This lesson is from “Web Weather for Kids” and can be found at http://eo.ucar.edu/webweather/lightningact.html Ask the class, “CHILDREN HAVE YOU EVER SEEN A BOLT OF LIGHTNING DURING A THUNDERSTORM?” and ask them how they feel about lightning. After listening to a couple of answers give a brief explanation of what lightning is. Lightning is a result of static electricity building up in thunderstorms and in the landscape beneath them. Today we’re going to listen for lightning in our groups. Each group will need the following materials: o A small chunk of polystyrene (Styrofoam.) o A wool sock o A bag of paper pieces Explore: In front of the class take a piece of polystyrene and a wool scarf, hat or sock and rub the polystyrene with the material vigorously for a minute or more until you feel some warmth being generated. Ask the children to gather around and listen very carefully to see if they can hear any small pops or clicks as the static electricity builds up Tell the children they will be also be doing this in their groups after your demonstration

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
