A testable idea about a set of observations or a natural phenomenon is known as a hypothesis. For example, if we observe that plants grow taller in direct sunlight compared to those in the shade, we could formulate the hypothesis that "increased sunlight exposure leads to greater plant growth." This hypothesis can be tested through experiments by measuring growth in varying light conditions, allowing us to gather data to support or refute the idea.

What is a word for a testable idea or explanation that leads to scientific investigation?
hypothesis
What is the definition of a scientific idea?
A scientific idea is a concept or hypothesis that seeks to explain natural phenomena based on empirical evidence and observation. It is often formulated through the scientific method, which involves observation, experimentation, and validation. Scientific ideas must be testable and falsifiable, allowing them to be supported or refuted through further investigation. Ultimately, they contribute to the broader understanding of the natural world.
How does a hypothesis help scientists understand natural world?
A hypothesis provides a testable explanation for a scientific phenomenon or observation. It helps scientists make predictions and design experiments to gather data that either supports or refutes the hypothesis, leading to a deeper understanding of the natural world. By systematically testing hypotheses, scientists can refine their understanding of how the world works through the process of scientific inquiry.
What was a testable idea that Ernest Rutherford developed in his experiments?
Ernest Rutherford's testable idea was that atoms have a small, positively charged nucleus at their center. He conducted the famous gold foil experiment, in which he observed the scattering of alpha particles, to support this concept. This experiment provided evidence for the existence of a dense nucleus within atoms.
A conclusion about how or why something occurs in nature supported by testing?
The conclusion is drawn based on empirical evidence gathered through controlled experiments or observations in nature. By systematically testing hypotheses and analyzing the results, scientists can provide a confident explanation for the occurrence of a particular phenomenon in nature. This process enhances our understanding of natural processes and enables us to make reliable predictions about future events.
Why is a hypothesis important in research?
To form an experimentally testable idea to explain observations.
What is a testable idea that attempts to explain a phenomenon or answer a scientific question?
A testable idea that explains a phenomenon is a hypothesis, which is a specific prediction that can be tested through experimentation or observation. For example, if we want to understand the effect of sunlight on plant growth, a testable hypothesis might be, "If plants receive more sunlight, then they will grow taller compared to plants that receive less sunlight." This hypothesis can be tested by measuring the growth of plants under different light conditions.
Where did Darwin make his first observations about evolution?
The Galapagos Islands is where he came up with the idea of natural selection.
What is a testable idea or explanation that leads to scientific investigation called?
A testable idea or explanation that leads to scientific investigation is called a hypothesis. It is a proposed explanation for a phenomenon that can be tested through experimentation and observation. A hypothesis must be specific and measurable, allowing scientists to gather data to support or refute it. This process is fundamental to the scientific method, enabling researchers to draw conclusions based on empirical evidence.
Which of the following best describes a theory?
A theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence and has withstood repeated testing and scrutiny. It integrates a wide range of observations and hypotheses to provide a coherent understanding of a phenomenon. Unlike a simple idea or speculation, a theory is rigorously validated and can be used to make predictions about future events or observations.
What is an idea that is based on many detailed observations?
An idea based on many detailed observations is an empirical theory. This type of theory is grounded in data gathered from systematic and careful observations of the natural world. The strength of an empirical theory lies in its ability to make predictions and be tested through further experimentation.
A testable idea or explanation that leads to scientific investigation?
A hypothesis.
What is a testable idea or explanation that leads to scientific investigation?
A "hypothesis".
A testable idea or experiment that leads to scientific investagation?
the answer is hypothesis
What is the general purpose of a hypothesis?
The general purpose of a hypothesis is to propose a testable explanation or prediction for a phenomenon or problem in research. It guides the research process by providing a clear direction and focus for data collection and analysis.
Compare and contrast a theory and hypotheses?
A theory is a well-supported explanation for a phenomenon based on evidence and repeated testing. It is a broader concept that integrates various hypotheses into a coherent framework. In contrast, a hypothesis is a specific testable prediction or idea that is proposed to explain a particular phenomenon and can be tested through experimentation or observation.
What states an idea in a way that can be tested?
A hypothesis is a testable statement. It often follows the If..., then..., because...format.
