good example of this would be coming home after a day of work only to find that the porch light is out when you knew you turned it on before you left to work. While most may err on the side of caution‚ their own scientific method starts to formulate in their head to try to put the pieces of the puzzle together. The problem at hand‚ and the question that should be asked‚ would be figuring out how the porch light went off. This first step of the scientific method helps narrow down the goal to a single

My research is to determine if electricity moves better through thick wires or through thin wires. For this experiment I used two size D batteries‚ two flashlight bulbs‚ one 6.5 inch thin steel wool piece‚ one 6.5 inch thick steel wool piece‚ two 2 inch pieces of straw‚ and some electrical tape. Steel wool is a material made from thin fibers of steel made into a pad. (http://www.wisegeek.com/l-what-is-steel-wool.htm) There are many uses for steel wool. It can be used for sanding furniture‚ removing

see it in daily life. However‚ light bulbs and a magnetic compass can show you when something electrical is happening. By observing their behavior and making a few assumptions‚ you can begin forming ideas about electricity. This type of thinking is called “building a model”. INVESTIGATION ONE: WHAT IS NEEDED TO LIGHT A BULB? 1.1 Activity: Lighting bulbs in a loop Insert three D-cells into the battery holder (as in Figure 1.1)‚ and insert two ROUND bulbs (not long bulbs) into a pair of sockets.

Whether we know it or not the scientific method is being used in everything we do. For instance‚ I arrive at home after dark. After opening the door‚ I reach for the light switch. When I flip the switch to turn the light on nothing happens. Here is where I am going to start applying the scientific method. Why is the light out? My research is going to start with me looking at the switch to see if I was flipping the correct one. There are a lot of homes where the wall plate has multiple
