Designing & Evaluating a Habitat Solution — Drills · Grade 7 Science
Chapter: Ecological Evidence & Environmental DesignWhat these drills covers
By the end of Designing & Evaluating a Habitat Solution you should be able to:
- I can explain designing & evaluating a habitat solution.
- I can use evidence, a model, and stated assumptions to support a biological explanation.
4 questions, multiple choice, numeric and written answer, each with a worked explanation.
Vocabulary used: criterion, constraint, prototype, iteration, cost effectiveness.
Problem 1
Which is a constraint?
- Maximum budget of 100 tokens
- Wanting more cover
- Liking a color
- A general hope
Answer and explanation
Maximum budget of 100 tokens
The budget limits feasible options; criteria measure desired performance.
Problem 2
A model runoff falls from 24 L to 9 L. Find reduction.
Answer and explanation
15 L
24−9=15 L under the supplied comparison.
Problem 3
How is a criterion different from a constraint?
Answer and explanation
A criterion evaluates success; a constraint limits allowable options, such as a maximum budget or available area.
Problem 4
Does a lower-cost design automatically win?
Answer and explanation
No. Cost is one criterion and feasibility limit; outcomes and other requirements also matter.
