Problem Analysis:
The task is to order the events in the scientific process based on the passage provided. The passage describes the steps scientists follow when conducting experiments:
1.
Observation: Scientists observe the world around them.
2.
Hypothesis: Based on their observations, they come up with a hypothesis (a guess or proposed explanation).
3.
Experiment: They design an experiment to test their hypothesis.
Solution:
We need to match these steps with the given options and place them in the correct order:
-
Step 1: "Scientists observe the world around them."
-
Step 2: "Scientists come up with a hypothesis."
-
Step 3: "Scientists design an experiment to test their hypothesis."
Correct Order:
1.
Scientists observe the world around them. → This is the first step, as observation leads to questions.
2.
Scientists come up with a hypothesis. → After observing, scientists form a hypothesis to explain what they observed.
3.
Scientists design an experiment to test their hypothesis. → Finally, they design an experiment to test whether their hypothesis is correct.
Final Answer:
-
Step 1:科学家观察周围的世界。 →
3
-
Step 2:科学家提出一个假设。 →
1
-
Step 3:科学家设计一个实验来测试他们的假设。 →
2
