Investigating the Mystery of Maple Trees Dropping Their Leaves
What are the possible stages of investigating whether maple trees drop their leaves in the autumn due to colder days?
1. Maple trees are grown in two greenhouses where the only variable is temperature (15°C vs. 10°C).
2. The hypothesis is rejected.
3. There is no statistical difference in the number of leaves dropped at 10°C as compared to 15°C.
4. The observation is that maple trees drop their leaves in autumn.
5. The hypothesis is that maple trees drop their leaves because of colder temperatures.
Solution to the Mystery
The appropriate order of the stages of investigating whether maple trees drop their leaves in the autumn because of colder days is as follows:
1. Maple trees are grown in two greenhouses where the only variable is temperature (15°C vs. 10°C).
2. The hypothesis is that maple trees drop their leaves because of colder temperatures.
3. There is no statistical difference in the number of leaves dropped at 10°C as compared to 15°C.
4. The observation is that maple trees drop their leaves in autumn.
5. The hypothesis is rejected.
In order to investigate the mystery of why maple trees drop their leaves in the autumn due to colder days, it is essential to follow the correct stages of investigation. The process includes the following description:
At the initial stage, the observation is made that maple trees drop their leaves in autumn, prompting the need for further investigation. The hypothesis is then formed, suggesting that colder temperatures are the cause of this phenomenon.
Subsequently, maple trees are cultivated in two separate greenhouses with different temperature variables (15°C and 10°C) to observe leaf dropping patterns. Statistical analysis reveals no significant difference in leaf drop between the two temperatures.
As a result, the initial hypothesis that colder temperatures trigger leaf dropping is rejected, leading to a better understanding of the behavior of maple trees in autumn. This investigative process helps unravel the mystery behind maple trees shedding their leaves.
