Graphing Speed -
Will was instructed to create a graph, with time on the x-axis and distance on the y-axis. He quickly identified that the graph would be illustrating speed. I then asked him to make a graph of a car that was not moving. He noticed that the graph was a straight horizontal line. After reviewing what constant meant, Will constructed another graph, this time for a car traveling at a constant speed of 1 mile per hour for 4 hours. The line was straight and diagonal. We added another car that was traveling at a constant 2 miles per hour, and noticed that the line was also straight and diagonal, but reached the four-mile target in a shorter amount of time. Will made one more graph showing a car that increased its speed from zero to four miles per hour. This graph read as a curved line. Will put his graphs into his science notebook. Homework: review the maps and what they illustrate.
