The image provided is a worksheet for designing and conducting a scientific experiment. It is divided into several sections:
Purpose,
Hypothesis,
Materials,
Procedure,
Results, and
Conclusion. Below, I will explain how to fill out each section with an example experiment.
Example Experiment: "Does the amount of sunlight affect plant growth?"
#### 1.
Purpose
- The purpose is what you want to investigate or learn from the experiment.
-
Example:
*I wonder if the amount of sunlight affects how tall plants grow.*
#### 2.
Hypothesis
- A hypothesis is an educated guess about what you think will happen in the experiment.
-
Example:
*I think that plants exposed to more sunlight will grow taller than plants exposed to less sunlight.*
#### 3.
Materials
- List all the materials you will need to conduct the experiment.
-
Example:
- 2 identical pots
- 2 identical plants (same species and size)
- Soil
- Water
- Measuring tape
- Timer or clock
- Notebook for recording data
#### 4.
Procedure
- Describe the steps you will take to conduct the experiment.
-
Example:
1. Plant one seedling in each pot using the same amount of soil.
2. Place both plants in a location where they receive equal amounts of water and care.
3. Place one plant in a sunny spot (e.g., near a window) and the other in a shaded spot (e.g., away from direct sunlight).
4. Measure the height of each plant at the start of the experiment.
5. Water both plants equally every day.
6. After 2 weeks, measure the height of each plant again.
7. Record the measurements in a notebook.
#### 5.
Results
- Record the observations and data collected during the experiment.
-
Example:
- At the start of the experiment, both plants were 5 cm tall.
- After 2 weeks:
- Plant in the sunny spot: 15 cm tall
- Plant in the shaded spot: 8 cm tall
#### 6.
Conclusion
- Summarize what you learned from the experiment and whether your hypothesis was supported.
-
Example:
*I learned that the amount of sunlight does affect plant growth. Plants exposed to more sunlight grew taller than those exposed to less sunlight. My hypothesis was correct.*
Final Answer:
-
Purpose: I wonder if the amount of sunlight affects how tall plants grow.
-
Hypothesis: I think that plants exposed to more sunlight will grow taller than plants exposed to less sunlight.
-
Materials: 2 identical pots, 2 identical plants, soil, water, measuring tape, timer, notebook.
-
Procedure: Plant seeds, place one in sunlight and one in shade, measure heights, water daily, record data after 2 weeks.
-
Results: Plant in sunlight grew to 15 cm; plant in shade grew to 8 cm.
-
Conclusion: Sunlight affects plant growth; my hypothesis was correct.
