# Iguana Home Task

### Evaluate and explain how to fix the habitat of a classroom iguana.

In the *Iguana Home* task, students help troubleshoot and fix the habitat for a classroom iguana named "Iggy." Students first learn about iguanas and their basic needs, and then they work through the task to determine how best to fix Iggyâ€™s wire mesh cage.

67%

of students were able to analyze and identify a design problem.

8%

of students successfully explained how a set of design changes could solve a problem.

69%

of students were able to recognize requirements and critique a proposed design solution.

Explore task details by selecting a step below

Step 1

Evaluating the Cage Design to Solve Problem 1

Students consider design solutions and make predictions for solving the problem of Iggyâ€™s cage being too cold.

Step 2

Evaluating the Cage Design to Solve Problem 2

Students consider design solutions and make predictions for solving the problem of Iggy being awake and active at night.

Step 3

Testing the Cage Design and Evaluating Alternative Solutions

Students observe Iggyâ€™s behavior to determine whether the proposed cage design solutions solve Iggyâ€™s problems.

Step 4

Redesigning the Cage to Prevent Dehydration

Students select a cage redesign to prevent dehydration.

A Closer Look: Students' Abilities to Evaluate Design Options, Predict Outcomes of Design Changes, and Explain Design Solutions

Six percent of students could identify an unmet design requirement, predict the outcome of a design change, and explain how design changes could solve a problem.
