Digital Story Assignment: Position-Time Graphs

Digital Story Assignment: Position-Time, Velocity-Time, and Acceleration-Time Graphs

This assignment will involve creating a video or PowerPoint presentation (or acting the situation out). You are welcome to use your smartphones to tape the video or create a slideshow. Other options include Movie Maker or iMovie.

This project can be done in groups of 2 to 4 people (no more). Everyone must discuss one portion of the graph within the movie or presentation. These will be played for the class at a later date (or acted out – your choice).

The final product should be approximately 2 to 3 minutes in length. If you would prefer to act it out or speak alongside the slideshow that is fine as well. As long as it is narrated!

You have 3 days to work on this. One day this week (planning) and two next week.

Instructions:

1) Create a position-time graph. Your graph must include: a. Total of at least 4 sections of graph i. At least one curved section. ii. At least one horizontal section. iii. At least one sloped section. b. Properly Labeled i. Labels ii. Scale iii. Units (m, km, etc and s, min, hr  your choice)

2) Describe each section of the graph in as much detail as possible. This means discussing where the object started from in reference to the reference point (or origin). It also means finding the displacement of the object over each time interval along with the velocity (speed and direction!). You should also think about comparing the speed of each section, if the object stops at all, etc. You may want to write this up in paragraph form or in table format. This will not be needed for the video but must be handed in.

a. Include at least one example of instantaneous velocity b. Include at least one example of average velocity c. Include at least one example of time and displacement/distance d. Describe when the acceleration occurs and what type it is.

You may find using a table such as the one below helpful: Section What does it What does it What does it Description of look like on d-t look like on v-t look like on a-t Motion graph? graph? graph? AB BC CD

3) Come up with a story regarding your position time graph. Include the mode of transportation and an object that you can use in the story. You may also want characters, etc.

4) Describe the object’s motion in a complete story. Be descriptive but make it sound like an actual story. You will narrate this story (or act it out) in the video.

5) Create a v-t and an a-t graph to go along with the story.

6) Create a powerpoint or movie (or similar – just ask your teacher first!) that involves the graphs with the descriptions as well as pictures or video captivating the story. Each type of graph should be featured at least once during the film. 7) Practice reading the story so it flows well. You can read the story as your powerpoint flows if you want. You can record it and play it along with the powerpoint if you would prefer. 8) You may want to add sound effects or songs to add to it! Have fun!

What do I need to hand in?

Each group must hand in a movie or powerpoint (or similar) unless they are acting out the scenario.

Each group must hand in a set of 3 graphs. They can be hand drawn or done on computer. Each graph must be labeled, scaled, have units, be drawn with a ruler (for all straight lines).

Each individual must hand in a paragraph outlining what they contributed, how the group worked together, what they enjoyed/didn’t enjoy about this project, and any improvements to the project.

Your group must hand in the project as 1 project. ALL TOGETHER. Neatly.

Rubric:

What am I looking for? Point Value d-t graph - properly labeled (labels, 7 pts scale, units) - neat graph (use a ruler or computer) - all components (curved section, horizontal section, sloped section) Description of the story - narration goes with graph 10 pts (each section is described) - narration is audible (I can understand what you are saying! You are loud enough!) - use of physics key terms (like velocity or speed, etc) Written description of - hand in a detailed 10 pts story description of the graphs - calculations of some values on the graph (with units and directions if needed) v-t graph - must go with your d-t 5 pts graph (all sections match up) - neat graph - properly labeled Video - creativity 10 pts - narrated properly (can be heard and understood) - good use of pictures/acting/etc a-t graph - must go with d-t and v-t 5 pts graphs (all sections match up) - neat - properly labeled Reflection - how did you contribute to 3 pts the group? - how did the group work together? - what did you enjoy/not enjoy about this project? - what would you change?

Total: 50 pts
