River Flow Investigation

Name:

Date:

🔬 Part 1: Planning Your Investigation

1. What do you think will happen to water flow in each setup? Write your hypothesis for each:

Flat straight river: ________________________________

Tilted straight river: ________________________________

Flat river with meanders: ________________________________

Tilted river with meanders: ________________________________

Flat river with obstacles: ________________________________

Flat river with different obstacle sizes: ________________________________

2. Which setup do you predict will have the fastest flow rate?

Flat straight river

Tilted straight river

Flat river with meanders

Tilted river with meanders

Flat river with obstacles

3. List the materials you will need for this investigation:

📊 Part 2: Recording Your Results

4. Time how long it takes for water to flow through each setup (record in seconds):

Flat straight river: _______ seconds

Tilted straight river: _______ seconds

Flat river with meanders: _______ seconds

Tilted river with meanders: _______ seconds

Flat river with obstacles: _______ seconds

Flat river with different obstacle sizes: _______ seconds

5. Describe what you observed about the water flow in each setup:

6. Which setup had the fastest flow? Which had the slowest?

Fastest: ________________________________

Slowest: ________________________________

🤔 Part 3: Analysis and Conclusions

7. What effect does slope (tilt) have on river flow rate?

8. How do meanders (bends) affect water flow compared to straight rivers?

9. What happens when obstacles are placed in the river?

Water flows faster

Water flows slower

Water changes direction

Water builds up behind obstacles

10. Explain why your results support or contradict your original hypothesis:

11. How might this investigation help us understand real river systems and flooding?
