Consider whether each of the following practices is appropriate or inappropriate for the age level, according to the principles of Piaget and contemporary researchers following in his tradition. Question 1 A high school science teacher asks students in a chemistry lab to answer thequestion “Does water boil faster when more heat is applied?” He gives them the equipment theyneed and shows them how to use it safely, and he monitors their procedures to make sure theyare following his safety guidelines. The students are able to conduct their investigations fairlyindependently, but seem to benefit from the teacher’s occasional guidance about how they mightmodify their procedures for clear-cut results. Appropriate Not Appropriate As she sits in her high chair, 6-month-old Deena keeps throwing the toys her father places on her tray, despite her father’s pleas that she stop. Exasperated, the father scolds Deena and puts her in her crib—where there are no toys at all—to show Deena that toys are not meant to be thrown. Appropriate Not Appropriate When a third-grade class takes a field trip to Rocky Mountain National Park, a park ranger gives a short lecture explaining how the Rocky Mountains were formed by forces pushing upward from within the earth. Not Appropriate Appropriate Question 7 After reading a children’s book that describes Columbus’s voyage to the New World in 1492, a first-grade teacher asks students to consider what might have happened if Columbus had never made the trip.

Sunshine Music Shop bought a stereo for $800 and marked it up 30% on selling price. To promote customer interest, Sunshine marked the stereo down 10% for 1 week. Since busi- ness was slow, Sunshine marked the stereo down an additional 5%. After a week, Sunshine marked the stereo up 2%. What is the new selling price of the stereo to the near- est cent? What is the markdown percent based on the original selling price to the nearest hundredth percent?
Alvin Rose owns a fruit and vegetable stand. He knows that he cannot sell all his produce at full price. Some of his produce will be markdowns, and he will throw out some produce. Alvin must put a high enough price on the produce to cover markdowns and rotted produce and still make his desired profit. Alvin bought 500 pounds of tomatoes at 16 cents per pound. He expects a 10% spoilage and marks up tomatoes 55% on cost. What price per pound should Alvin charge for the tomatoes?

Suppose you are considering renting an apartment in a building in which the tenants are required to pay the cost of heating their apartments. The building has several apartments, each occupying an entire floor of the building. The building has a flat roof. You are attracted to the apartment on the top floor because of the view but your friend tells you that the heat bills will be higher for that apartment than for the ones on the lower floors.
a. [3pts] Is your friend likely to be right? Explain why or why not
in terms of the expected thermal energy flows in and out of the
apartments.
b. [4pts] Defend your answer to a. by calculating the amount of
energy required to heat the top and lower apartments for a year in
btu. Include the lowest apartment assuming that it is just above
the ground (no basement below it). Suppose that the floor area of
each apartment is 900 sq ft (30ft x 30ft) and that the height from
one floor to the next is 10ft. Use 8500 as the number of ’degree
days’ in Minnesota (Figure 5.12 and definition near the top of p.
137) and the R values given in Table 5-1 of the book (1978
values).
c. [3pts] Use the answer you got in b. to calculate the difference
in cost (if any) between heating the top apartment for a year
,heating a lower apartment for year, and heating the ground floor
apartment for a year, supposing that the cost of gas heating is
$0.80 per ’therm’. 1 therm=100,000 btu.

Joan Frazier was just hired as an employee by SJR Restaurants,
Inc., a Delaware Corporation domiciled in Colorado. Ms. Frazier
maintains a residence in Orange County, California, so her children
may attend the schools of her choice and so that her husband may be
employed there as a leading plastic surgeon.
SJR has just opened three (3) restaurants in Utah, Nevada, and
Idaho. SJR requires Ms. Frazier set up the general ledger
accounting system at each restaurant. SJR estimates it will take
Ms. Frazier 14 months of continuous, full time work (40 hours per
week, 4 weeks per month) to set up the systems. SJR requires Ms.
Frazier to rotate her time. That is, to spend time at each
restaurant at least once a calendar quarter. Each restaurant has an
office for the accounting function, although the offices are so
small that Ms. Frazier does a majority of her work from hotel rooms
near the restaurants.
Ms. Frazier reports back electronically to SJR. Ms. Frazier is
never required to go to Colorado. SJR does not reimburse Ms.
Frazier for her lodging, travel, or meal expenses.
May Ms. Frazier deduct lodging, travel, and meal expenses?

In order to test a hypothesis and prediction, controlled experiments are used. Controlled experiments involve several necessary components. An independent variable is usually manipulated by a researcher but does not change as a result of the experiment. The changes in the dependent variable may be caused by the experiment (and depend upon the independent variable). Graphs that depict the experimental data list the independent variable on the x-axis while the y-axis shows the dependent variable.
A commonly used mnemonic (memory device) to aid in distinguishing the characteristics of the types of variables is DRY MIX.
D = dependent variable (depends on the other) R = responding variable (one that changes) Y = y-axis on a graph M = manipulated variable (one that is changed by the researcher) I = independent variable
X = x-axis on a graph
The following sentence is a template to write an if/then statement to be used as a prediction:
If the independent variable is changed [increased, decreased, etc.], then the dependent variable will change in this way [increase, decrease, etc.]. Example: If the amount of available light increases, then plant growth will increase.
Discussion Questions:
Use the tools and examples just discussed to answer the questions about the experiment scenario described next. Jonah and Tessa noticed that some Leopard frogs by a local river had extra limbs. They decided to check various areas along the river to make more observations. They recorded their observations in their field notebooks. Jonah and Tessa performed a simple laboratory experiment with Leopard frog eggs and river water taken at various spots along the river. They noticed that adult frogs developing from eggs in water collected near an industrial park showed more deformities, but the deformities seemed to be different than those seen on frogs in the natural setting by the river.

You operate your own small building company and have decided to bid on a government contract to build a pedestrian walkway in a national park during the coming winter. The walkway is to be of standard government design and should involve no unexpected costs. Your present capacity utilization rate is moderate and allows sufficient scope to understand this contract, if you win it. You calculate your incremental costs to be $268,000 and your fully allocated costs to be $440,000. Your usual practice is to add between 60% and 80% to your incremental costs, depending on capacity utilization rate and other factors.
