Students are asked to conduct two investigations. The first investigation uses scientific practices to find out how birds glide in the air. The second investigation uses engineering practices to design a plane that would glide easily in the air. Select the choices of the practices that would only be used in the second investigation.
Use a model to make a prediction.
Use a model to test a solution to a problem.
Ask questions and seek answers in a systematic way.
Define a problem and look for a solution in a systematic way.
Clearly define a need and the criteria or constraints for the solution.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
