Printable science investigation planning sheet for students to outline experiments.

The image provided is a template for a science investigation. To solve the problem and explain the solution, I will guide you through filling out each section of the worksheet with an example scenario. Let's assume the investigation is about "How does the amount of sunlight affect plant growth?".

Step-by-Step Solution:

#### 1. Aim
- The aim is the main objective or purpose of your investigation.
- Example:
To investigate how the amount of sunlight affects the growth of bean plants.

#### 2. Hypothesis
- A hypothesis is an educated guess or prediction about what you think will happen in your experiment.
- Example:
If the amount of sunlight increases, then the height of the bean plants will increase.

#### 3. Independent Variable
- The independent variable is the factor that you manipulate or change during the experiment.
- Example:
Amount of sunlight (measured in hours per day).

#### 4. Dependent Variable
- The dependent variable is the factor that you measure to see how it responds to changes in the independent variable.
- Example:
Height of the bean plants (measured in centimeters).

#### 5. Method
- This section outlines the steps you will follow to conduct your experiment.
- Example:
1. Prepare the setup: Plant 10 bean seeds in individual pots filled with soil. Ensure all pots have the same type and size of soil.
2. Divide into groups: Label three groups of pots as Group A (6 hours of sunlight), Group B (8 hours of sunlight), and Group C (10 hours of sunlight).
3. Control conditions: Place each group under controlled conditions where they receive the specified amount of sunlight daily.
4. Watering routine: Water each plant with the same amount of water (e.g., 200 mL) every other day.
5. Measure growth: Measure the height of each plant weekly using a ruler and record the data.
6. Repeat measurements: Continue measuring the height of the plants for 4 weeks.

#### 6. Controlled Variables
- Controlled variables are factors that remain constant throughout the experiment to ensure fairness and accuracy.
- Example:
- Type of soil used
- Amount of water given to each plant
- Size of the pots
- Temperature of the environment
- Age of the bean seeds

#### 7. Equipment
- List the materials and tools needed to conduct the experiment.
- Example:
- Bean seeds
- Pots
- Soil
- Ruler
- Watering can
- Timer/light source for controlling sunlight exposure
- Notebook for recording data

#### 8. Conclusion
- The conclusion summarizes the results of your experiment and whether your hypothesis was supported or not.
- Example:
After conducting the experiment for 4 weeks, it was observed that the plants in Group C (10 hours of sunlight) grew the tallest, followed by Group B (8 hours of sunlight), and then Group A (6 hours of sunlight). The data supports the hypothesis that increasing the amount of sunlight leads to increased plant growth. However, further experiments could explore the effects of different types of light or varying water amounts.
