Scientific Method and Plant Experiments

This video tutorial by Kak Febri on the Sigma SM Study channel covers the scientific method and how to design experiments. It explains the steps involved in conducting experiments, including observation, hypothesis formation, and data collection. The video also discusses different types of variables: independent, dependent, and controlled. Through examples, it illustrates how to apply the scientific method to real-world scenarios, such as studying the effect of sunlight on plant color. The tutorial aims to enhance understanding of scientific processes and encourage viewers to engage in scientific inquiry.

What is the first step in the scientific method?

• Formulating a hypothesis

• Conducting an experiment

• Making an observation

• Drawing a conclusion

Which of the following is an example of a dependent variable?

• Watering frequency

• Plant growth

• Type of soil

• Amount of sunlight

What is a controlled variable in an experiment?

• A variable that is changed to see its effects

• A variable that is kept constant

• A variable that is measured for changes

• A variable that is irrelevant to the experiment

In the plant experiment, what was the independent variable?

• Type of plant

• Amount of water

• Intensity of sunlight

• Color of the plant

What hypothesis was tested in the plant experiment?

• Plants grow faster with more water

• Sunlight affects the freshness of plant color

• Different soils affect plant height

• Temperature changes plant growth

What is the purpose of taking photos during an experiment?

• To create a presentation

• To visually document changes

• To compare with other experiments

• To share on social media

What conclusion was drawn from the plant experiment?

• Plants need more water to grow

• Sunlight does not affect plant color

• Sunlight enhances the green color of plants

• Different plants react the same to sunlight

What is the final step in the scientific method?

• Conducting further experiments

• Publishing the results

• Reviewing the hypothesis

• Making a conclusion

What is the role of a hypothesis in an experiment?

• To predict the outcome

• To provide a final answer

• To list the materials needed

• To summarize the results
