What is the Gizmo Natural Selection Activity?
The Gizmo Natural Selection activity is an interactive simulation designed by ExploreLearning that models how environmental pressures influence the traits of a population over time. Students can manipulate variables such as mutation rates, environmental conditions, and trait distributions to observe how populations adapt or fail to adapt.
Key features of the Gizmo Natural Selection activity include:
- Visualization of populations with different traits
- Ability to change environmental factors
- Observation of trait frequency changes over successive generations
- Data collection and analysis tools
This activity helps students understand core concepts such as variation, competition, survival, and reproduction—all central to the theory of natural selection.

Detailed Breakdown of the Natural Selection Gizmo and Its Components
To effectively utilize the answer key, understanding the structure of the Gizmo activity is crucial. Below is a detailed breakdown of its main components:
1. Population Setup
- Users select traits for the initial population, such as beak size, coloration, or body length.
- The initial distribution of traits can be uniform or varied.
2. Environmental Conditions
- Settings for environment factors like food source size, predator presence, or climate.
- Changes here influence which traits are advantageous.
3. Simulation Controls
- Buttons to start, pause, or reset the simulation.
- Options to accelerate or slow down the simulation.
4. Data Collection and Graphs
- Charts display how trait frequencies change over generations.
- Data tables for quantitative analysis.
5. Questions and Challenges
- Embedded questions prompt learners to analyze what they observe.
- Challenges to modify variables and predict outcomes.
Understanding these components allows students to better interpret the answer key and the rationale behind each response.

Common Questions and Corresponding Answers in the Gizmo Natural Selection Activity
Below are some typical questions from the activity, along with detailed answers and explanations to help clarify the concepts:
Q1: What happens to traits that are advantageous in the current environment?
Answer: Traits that confer advantages in the current environment tend to increase in frequency over generations. This is because individuals with advantageous traits are more likely to survive, reproduce, and pass on these traits to their offspring. For example, if a larger beak allows better access to food sources, populations with larger beaks will become more common over time.
Q2: How does environmental change affect the direction of evolution?
Answer: Environmental changes can alter which traits are advantageous. When conditions shift, traits that were once beneficial may become neutral or detrimental. This causes the population to adapt to the new environment, leading to a change in trait frequencies. For instance, if predators prefer prey with certain coloration, changing predator behavior can shift the selective pressure.
Q3: Why do some traits become more common while others diminish?
Answer: Traits become more common if they increase survival and reproductive success under specific conditions. Conversely, traits that decrease survival chances tend to diminish over time because individuals with these traits are less likely to reproduce successfully.
Q4: How does genetic variation influence natural selection?
Answer: Genetic variation provides the raw material for natural selection. Without variation, populations cannot adapt to changing environments. Variation arises through mutations, genetic recombination, and other mechanisms, enabling populations to evolve in response to environmental pressures.
Q5: What role do mutations play in the evolution of populations?
Answer: Mutations introduce new traits into a population. While most mutations are neutral or deleterious, some confer advantages that can be selected for over generations. Mutations are a crucial source of genetic diversity, fueling evolution.
