Question

If the road is larger then there will be fewer birds crossing, fewer birds living in the nearby forest, and different types of birds that do cross the road, compared to smaller roads

1. Observation
2. Question
3. Collect Evidence
4. Hypothesis

Answer 1

To construct a traffic flow model, you would measure a section of road to observe traffic flow and record the time it takes for cars to travel that section. However, the model cannot test the gravitational pull on each vehicle or the average speed of vehicles at 40 mph.

Step-by-step explanation:

The steps to construct a traffic flow model and test hypotheses include:

1. Measure out a section of a road to observe traffic flow
2. Record the time it takes for cars to travel the measured section
3. Design a table to represent the results and use them to answer the aim of the investigation

Limitations of the model include:

• It cannot test the gravitational pull on each vehicle while in motion
• It cannot test the average speed of vehicles at 40 mph

Answer 2

Observation: The passage describes that when roads are larger, there will be fewer birds crossing, fewer birds living in nearby forests, and different types of birds that do cross the road, compared to smaller roads.
Question: How does road size affect the number and types of birds crossing, living in nearby forests?
Collect Evidence: To investigate this question, researchers could conduct surveys and/or studies to gather data on the numbers and types of birds crossing and living in nearby forests of different-sized roads. They could also collect data on road size and other factors that might influence the presence and abundance of birds.
Hypothesis: The passage implies that larger roads have a negative impact on the number and types of birds crossing and living in nearby forests compared to smaller roads. But the statement does not provide clear hypothesis, it just presents an observation. But this could be the starting point for a research.
