How do scientists systematically approach the process of inquiry and discovery to expand their understanding of the world?

How do scientists use evidence and reasoning to formulate and test hypotheses?

A junior high school student wants to determine which fertilizer (organic or synthetic) promotes the greatest plant height and leaf area in tomato plants within a controlled environment. How does a well-defined aim contribute to the overall successful experimentation?

A junior high school student conducting a biology experiment to investigate the effects of different pH levels on plant growth. Which part of scientific method can determine the essential tools and supplies required to conduct a specific experiment?

The medical research study on a new vaccine provides a concrete context. A well-defined plan in this research would ensure that the vaccine is tested under controlled conditions, with clear variables and measurable outcomes. Which part of scientific method can reduces the likelihood of errors and biases, leading to more accurate and reliable results.

A group of students conducted an experiment to determine the effects of different types of water samples. Which part of scientific method can these students effectively communicate their findings to others, ensuring that their report is clear, comprehensive, and convincing.

Imagine a biologist studying the effects of different fertilizers on plant growth. Which part of scientific method can biologists effectively document the findings of their experiments and ensure that all relevant information is captured?

What is an idea or explanation that you test through study and experimentation?

9. What is the factor you deliberately change or manipulate in your experiment to see its effect on something else?

Which factors should be kept consistent for a fair experiment?

Hypothesis is an educated guess.

Variables is anything that can change or be changed within an experiment

All plants should be exposed to the same amount of sunlight. It is an example of Controlled Variables.

The height of the plants. Is an example of Dependent Variables

The amount of fertilizer applied to the plants. Is an example of Dependent Variables

Which among these are NOT a good aim?

Which among these are not consider in Materials and Equipment

Which among these are not included in Method and procedure?

Which are not included to consider in Results including data?

A scientific investigation which include: Aim or problem, Materials and equipment, Method or procedures, Results including data, and Conclusions.
