Demand Survey
Circle the product that has been assigned to your group.
Divide the class into six groups. Assign one of the products listed under “Get Started” to each group. The instructions for this activity are also listed on the student handout and the teacher’s lesson plan. The numbers used on the slideshow are just for example purposes. When students complete the lesson, they should obviously use the numbers they get during the survey, and not copy what is on this slideshow.

The tricky part of this exercise is to fill in the “Actual Demand” column correctly. Remember, demand is a cumulative total here because those who are willing to pay a high price will definitely also be willing to pay for the same item at a lower price. Add the number from the next row to the number in the previous row. Once you get this new total, write it in that row. Next, add the next row’s number to the new total you just got. Keep adding cumulatively like this to get the “Actual Demand” column. Click the second “Fill in This Column” button for the example.

Their graph should look something like this. Ask students to answer the question on the bottom of their sheet. Their answer should be something like “when price gets bigger, the quantity demanded gets smaller.”

16. Demand Can Change in Two Ways
1) Change in “Quantity Demanded”
This is just a change along the demand curve.

1) Change in “Quantity Demanded”
This is just a change along the demand curve.
For example, the price for lemonade
might change from $2.00 to $1.00

18. Demand Can Change in Two Ways
1) Change in “Quantity Demanded”
This is just a change along the demand curve.
Notice how the blue demand line did not move. Just price changed, so we moved from one “quantity” to another.
Allow students time to copy down the graph onto their note sheets.

Students do not copy down this graph right now. Move forward on the slideshow and it will walk everyone through the steps of graphing an increase in demand and graphing a decrease in demand.
Notice how the new blue demand line shows that more lemonade will be demanded at every price. D2

Increases Demand
There are six factors that will cause demand to increase.
1) Consumers enter the market $
2) Consumers have more money
This factor only holds true for normal goods. For inferior goods consumers will actually purchase less as they get more money.
Whenever people have more money (raise, tax refund, etc.), they are willing and able to spend it on more things.

Increases Demand
There are six factors that will cause demand to increase.
1) Consumers enter the market
2) Consumers have more money
3) Consumers expect good things to happen in the future
This factor is not always an absolute case. Sometimes a good thing in the future (like a holiday purchasing season and all of its sales) will cause demand to actually decrease in the present moment.
If consumers think they will have more money in the future or that the economy will grow (along with prices), they will purchase now.

45. Changes in Demand DIRECTIONS
On the front side, fictional newspaper headlines illustrate the market for butter. Determine if the quantity demanded changed (which means only the price of butter has changed), or if the entire demand has changed. If only quantity demanded changed, circle “No Change.” If the entire demand has changed, identify if it was an increase or a decrease, and identify which determinant of demand is responsible. The determinants of demand are listed in the box. On the back side, you will graph these changes.
GRAPH CHANGES IN DEMAND
For each of the headlines listed on the front side, draw the appropriate change in demand on the graph. Remember, an Increase means the line moves to the right, a Decrease means the line moves to the left, and No Change means the line stays the same.
