Supply & Demand Assignment


One member of your team must have a public twitter account and the twitter app loaded on their phone.


Film 3 different examples of something that shifts supply or demand in Bethany.

There must be at least one example of a supply shift and one example of a demand shift.

Something in the background of your video must coincide with your supply and demand example.

You cannot repeat the same cause of a shift twice - aka only one story on the change in population.

You cannot do the same story already cover by a different group, including groups from past years - watch #BethanySanD for what other groups are doing.

Each person in the group must be in front of the camera at least once; otherwise the missing person gets no credit.


I will grade the first 3 videos you post. Each correct example earns the group 3 points (up to 9).

Include title of video in your tweet (See Examples).

Posts must include the hashtage #BethanySanD and mention me (@AaronHonsowetz) at end of the tweet to count.

You can make up points for a wrong answer by correctly correcting a different group (all 3 points).


You can make more than 3 videos. (Additional videos only make up two points of a wrong answer).

The group with the most unique correct stories will earn 2 homework extra credit points.

(You can repeat different type of causes of a shift after your 5th video).
