7.P.1.3 When an object changes position over time relative to a reference point, the object is in motion. You can describe the direction of motion with a reference direction such as north, south, east, west, up or down. Collect and organize data to show how the motion of an object changes in position over a period of time. Communicate and graph data showing how the motion of an object changes in position over a period of time. 7.P.1.4 Students should collect and organize their own data for graphing distance versus time. Graphs for constant speed and variable motion. Students will interpret prepared graphs for distance versus time for constant speed and variable motion.

In your scientific journal, under that date of 9/17/13, please answer the following: What did William Hazlitt mean by the following quote: Everything is in motion. Everything flows. Everything is vibrating. 5 minutes

We are going to begin practicing how to graph. The Y axis goes up and down and the X axis goes right to left. Draw this!

Number your Y and X axis 1, 2, 3, 4, 5, 6.

The Y axis represents distance and the X axis represents time. Please graph the following story on the graph you created in your journal.

Starting at 0, please graph the following: 1. Tom left his house to take his dog for a walk. He walked 2 minutes and traveled 1 mile. Put a circle on the graph where Tom and his dog stopped. Label this dot 1.

2. Tom and his dog continued walking for 3 minutes and traveled 2 miles to reach the park. Please draw a circle on the graph as to where Tom and his dog stopped. Label this dot 2.

3. Now you need to help Tom and his dog get home. From where they are on the graph, what is the most direct way to get Tom home. What is the travel time and the distance?

Using the Y and X axis graph like below, without numbers, graph the following story.

Darcy the dung beetle was a happy little bug. One day, he decided to take a walk to the nearby dump. He left his home and crawled at a calm, constant pace. He sat down and remained there at the dump and enjoyed his meal most of the afternoon. After he was finished, he remembered an appointment with his friend. He quickly returned in the direction of his home, but passed his house and continued on until he reached his friend’s home.

Switch with your table mate and compare graphs. How can you tell when the bug is moving and when the bug is not moving?

Now we will discuss the following formula. Write this down!

The following calculations can be made simply by remembering this triangle! Write these down! Speed x Time = Distance Distance divided by Speed = Time Distance divided by Time = Speed
