What is the relationship between hypothesizing predicting and experimenting

you experiment to test the hypothesis and see if what you predicted was true or not. By using the gathered facts, a hypothesis tends to create relationships between different variables which will serve as the source of a more. The Scientific Method Objectives: List the steps of the scientific method Explain the relationship between hypothesizing, predicting, and experimenting.

Like a hypothesis, it is still another type of guess that can either be scientific or fictional even prophetic. A person who predicts usually has little or no knowledge of the subject matter being predicted although there are some predictions that may still be based on observable facts.

Fact vs. Theory vs. Hypothesis vs. Law… EXPLAINED!

With fictional predictions, however, you will usually encounter guessing the possible outcomes or events. One of the popular predictions today is the prediction of the end of the days which is bound to take place late in the year This will also lead to associating predictions with self-proclaimed prophets and fortunetellers alike.

Perhaps the biggest difference between the two is the methodology of proving each of them. A prediction can actually be proven either wrong or right with the non-occurrence or occurrence of a certain event. And the story ends after that. A hypothesis is a different story because its proving methods can be done in multiple stages.

This means that one scientist can disprove a hypothesis today by using his scientific system, and later on another scientist can prove that it is actually correct using another type of scientific tool. A hypothesis is a more intelligent guess. Hypotheses analyze the relationships between existing variables.

Hypotheses are usually structured longer than predictions. Testable prediction based on prior knowledge and observation. Can be supported or rejected based on an experiment. Broad explanation based on many experiments and high amounts of data.

Evolution, Plate Tectonics, Big Bang Discoveries must be reproducible -- designed and recorded such that the results can be repeated by other researchers. One recipe for life called for dirty garments and husks of wheat to be added to a jar.

Notes: Chapter Scientific Method

Wait 21 days, and mice appear! This belief was based in false science. Could it be replicated consistently? Were any other possible explanations tested? One of out every 10 children born in France and Sweden died of smallpox.

Some inoculated themselves with fluid and pus from the sick, hoping to contract a mild case and survive. He decided to intentionally infect a young boy with cowpox, then expose him to smallpox.

Notes: Chapter 2.1 Scientific Method

Immunity was successfully conferred to the boy. Produced much milder symptoms. Smallpox was declared eradicated by the World Health Organization in The same basic technique has been used to develop vaccines for other illnesses, such as measles, tetanus, chickenpox, whooping cough, and others.

This method consists of a series of steps that scientists worldwide use to identify and answer questions. Much Like cause and effect. Two Types of Observations: Graphs Data tables Graphic organizers Data: Information that a scientist gathers during an experiment.

Is drawn after a scientist analyzes the collected data and is compared to the hypothesis. Repeat experiment Communicate Results 18 The first step is making an observation. Information gathered by noticing specific details of a phenomenon. Edward Jenner observed that dairymaids who contracted cowpox seemed to be protected from the more deadly smallpox. Observing is the first step of the experimental method.

Observations can take many forms, including descriptions, drawings, photographs, and measurements. Forming a hypothesis is the second step of the experimental method.

A hypothesis is not merely a guess. A good hypothesis should make logical sense and follow from what you already know about the situation.

Hypotheses are preliminary explanations — they can and are often proven false. The hypothesis must be tested. A prediction is used to test a hypothesis. Every time a hypothesis is disproved, the number of possible explanations for an observation is reduced.

By eliminating possible explanations a scientist can zero in on the best explanation. A controlled experiment attempts to test a single variable, while keeping all others constant.

The experimental group receives the variable, while the control group does not. The boy experimental group survived 20 inoculations without succumbing to smallpox! An experiment is performed when questions that arise from observations cannot be answered with additional observations.

Experiments should be designed to pinpoint cause-and-effect relationships. The variable is the factor that changes in an experiment in order to test a hypothesis.

To test for one variable, scientists usually study two groups or situations at one time, with the variable being the only difference between the two groups.
