Question

mouse a finished the race 45 seconds earlier than mouse b. the timer was started. mouse a was allowed to smell a corn - pellet before starting the race. corn pellets smell good. mice have a good sense of smell. then the pellet was placed at the end of the maze. mouse b started the race without smelling the corn - pellet. at the end of the race, mouse a finished first. i think that mice will not need a keen sense of smell to find their way through a maze.

Explanation:

1. d: The problem/question is about whether mice need a keen sense of smell to find their way through a maze.
2. e: The hypothesis is a prediction, and "I think that mice will not need a keen sense" is a hypothesis.
3. g: Materials are the items used in the experiment, which are 2 mice, corn pellet, maze, timer.
4. f: The procedure describes the steps done in the experiment like letting mouse smell pellet, placing pellet at end of maze and starting timer.
5. b: The result is a factual outcome, here Mouse A finishing 45 seconds earlier than Mouse B.
6. c: Research can include background knowledge like mice having a good sense of smell and corn - pellets smelling small.
7. a: The conclusion is a statement about the overall finding, that mice need a keen sense of smell to find their way through a maze.
8. a: Observing a bird having to fly a great distance to find food is an observation.
9. b: Inferring that the birds do not have enough food to eat is an inference as it is a conclusion based on observations.
10. a: A bird's beak being 35 mm long is a quantitative observation as it involves a measurement.
