Natural selection practice
This 9th-grade classroom resource enables students to practice understanding natural selection by answering multiple-choice and sequencing questions focused on variation, overproduction, competition, survival, and reproduction, using real-world examples like peppered moths and antibiotic resistance. Students organize concepts, identify necessary conditions, and apply the steps of natural selection through structured questions.

Questions
- Which of the following best describes 'variation' in the context of natural selection?
- What is the main reason that overproduction of offspring leads to competition in a population?
- Which of the following are necessary conditions for natural selection to occur?
- Put the steps of natural selection in the correct order.
- Match each term to its correct example.
- Fill in the blanks: In the case of the peppered moth, after the Industrial Revolution, dark-colored moths had a _ chance of survival because they were _ against the soot-covered trees.
- Select the correct word for each gap: Antibiotic resistance in bacteria is an example of natural selection because bacteria with a _ that makes them resistant survive and _ when antibiotics are present.
- Sort each example as either 'Peppered Moth' or 'Antibiotic Resistance'.
- Decide if each statement about natural selection is true or false.
- What is the term for a genetic change that can give an organism an advantage in its environment? (Acceptable answers: mutation, mutations)
