Designing a Solar Oven A science class has been assigned the task of developing a simple solar oven using a cardboard box as the base. The solar oven should be able to melt cheese for nachos, and the temperature should reach at least 140 °F. The total cost of the materials used must be less than $10 and the size of the oven must be 24” x 24” or less. The required temperature must be met within 60 minutes. The final outcome of the class project should be that the oven uses solar energy to make a plate of nachos, reaching the minimum temperature in the required amount of time. Which statements describe constraints that the science class’s solar oven must meet? Choose all of the correct responses.

• It should use a box of some type.

• The total cost of materials should be $10 or less.

• It should be able to melt the cheese on the chips.

• It must reach the given temperature within one hour.

• It can be used by people in remote areas without access to electricity.

This table shows the results of the first test the class conducted using its solar oven design.

Which statement correctly evaluates the design of the class’s solar oven?

• The class’s design does not meet the temperature criterion because it exceeds the required temperature.

• The class’s design does not meet the temperature criterion because it never reaches the required temperature.

• The class’s design does meet the time criterion because it reaches the necessary temperature within

  60 minutes.

• The class’s design does not meet the time criterion because it does not reach the required temperature within 60 minutes.

Scientists take water samples from coastal waters to determine nitrogen levels in the water. Nitrogen levels in water are affected by acid rain. Increased nitrogen levels can have harmful effects on shellfish populations. Why is it important for scientists to study system interactions related to nitrogen levels in ocean water?

• The study of system interactions allows scientists to eliminate excess nitrogen from coastal waters.

• The study stops additional pollution and completely corrects the issue with the shellfish population.

• The study of system interactions related to water nitrogen levels provides information about air quality and about ocean food webs.

• The study of system interactions allows scientists to determine the causes of increased acid rain and prevent acid rain from harming the oceans.

A group of scientists is developing a small, working model of a solar-powered heating and cooling system. What is the purpose of building this model?

• to make sure the model can fit into small spaces

• to produce a working prototype for customers to use

• to test how changes in one part of the system affect other parts

• to ensure that all of the originally planned features remain the same
