Flashcard 1: What is the meaning of variable in a fair test about environment and traits?
Answer: One thing that can change in an investigation. Only one variable changes while others stay constant.
Flashcard 2: What is the meaning of adaptation in simple science terms?
Answer: A trait that helps an organism survive in its environment. Adaptations develop over many generations.
Flashcard 3: What is a claim in a science explanation?
Answer: A statement that answers a question about what happens. Claims are testable statements based on observations and data.
Flashcard 4: Which word means a trait passed from parents: inherited trait or acquired trait?
Answer: Inherited trait. Inherited traits come from genetic information in parents' DNA.
Flashcard 5: Which word means a change caused by the environment: inherited trait or acquired trait?
Answer: Acquired trait. Acquired traits develop during life due to environmental influences.
Flashcard 6: What is a trait in a living thing?
Answer: A characteristic of an organism, such as color or size. Traits are observable features that help identify organisms.
Flashcard 7: What does it mean when the environment affects a trait?
Answer: Conditions can change how a trait looks or works. Environmental factors can modify trait expression without changing genes.
Flashcard 8: What is an observation that counts as evidence about traits?
Answer: A trait difference you can see, hear, or measure. Observable differences provide concrete evidence about trait changes.
Flashcard 9: What should you change in a fair test about environmental effects on traits?
Answer: Only one environmental factor at a time. Testing one variable isolates its specific effect on the trait.
Flashcard 10: What should stay the same in a fair test when studying an environmental effect on a trait?
Answer: All factors except the one being changed. Controlling variables ensures only the tested factor causes changes.
Flashcard 11: What is the difference between inherited traits and environmental effects on traits?
Answer: Inherited come from parents; environmental effects come from conditions. Inherited traits are genetic; environmental effects develop from surroundings.
Flashcard 12: What is a claim when explaining how environment affects traits?
Answer: A statement that answers the question using evidence. Claims directly address the question and are supported by data.
Flashcard 13: What is the environment in science?
Answer: All living and nonliving things around an organism. Environment includes everything that surrounds and affects an organism.
Flashcard 14: What is evidence in a science explanation?
Answer: Observations or measurements that support a claim. Evidence must be factual data, not opinions or guesses.
Flashcard 15: What is the meaning of an organism's trait in science?
Answer: A characteristic of a living thing. Traits include physical features and behaviors.
Flashcard 16: What is the meaning of environment when explaining traits?
Answer: The surroundings and conditions where an organism lives. Includes air, water, temperature, and other organisms.
Flashcard 17: What is evidence in a science explanation about traits?
Answer: Observations or data that support a claim. Facts and measurements that prove something is true.
Flashcard 18: What is a claim in an explanation about environmental effects on traits?
Answer: A statement that answers the question. States what you think based on evidence.
Flashcard 19: What is a controlled variable in a fair test about environment and traits?
Answer: A factor kept the same for all groups. Controlled variables ensure only one factor causes observed changes.
Flashcard 20: What is the best evidence type for showing an environmental effect on plant growth?
Answer: Measurements of plant height or leaf number over time. Quantitative data shows changes over time, proving environmental impact.
Flashcard 21: What is the difference between inherited traits and learned behaviors?
Answer: Inherited are from parents; learned are from experience. Genes determine inherited; environment shapes learned.
