increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water? According to my hypothesis‚ once there is more dissolved oxygen in the water‚ there is an increase to the amount of fish present in the area where the water sample is obtained. 3. What would your experimental approach be to test this hypothesis? First‚ I would take a sample from different areas of the

to answer at the end of the experiment. For this experiment‚ my question is what (will) happen when air molecules expand. Thirdly‚ created the hypothesis to predict or guess what will happen in this experiment. Here‚ I think that air pressure will make the egg fit through the mouth of a bottle. After we have a topic‚ question and hypothesis‚ we can start preparing the materials which are needed in the experiment. In this experiment‚ we need hard-boiled egg‚ a glass bottle‚ piece of paper

paper is an examination of theories and hypotheses‚ their differences and similarities. The four major types of theories studied are Deductive‚ Inductive‚ Grounded and Axiomatic. Each type of theories is introduced and explained. Additionally‚ a hypothesis is defined in relation to a theory‚ and the key differences between the two explained. The variables which exist between the theories and the hypotheses is also explored. Theories and Hypotheses: The Differences

The scientific method is a logical organized mechanism for identifying and researching a problem and devising a strategy for solving it. c. In the problem or question step‚ the researcher must decide what it is that you will be studying what you wish to learn. d. The hypothesis is an educated guess.

can be tested. Your first step is to develop a hypothesis. A hypothesis is a possible answer to a scientific question or an explanation for a set of observations. Your hypothesis is not a fact. It must be tested. Your observations may support your hypothesis or they may not. If they do not support your hypothesis‚ you have not wasted your time. You have learned that your hypothesis is not correct and that you must explore further. Write a hypothesis about the volume of a balloon when the temperature

dry side. The constants kept throughout the experiment were the time length and the number of pill bugs. The bugs decided on the side with dirt so the hypothesis was rejected. They prefer the moisture in the dirt‚ so they chose that side rather than the side with nothing. Question: Do pill bugs prefer the side with dirt or no dirt? Hypothesis: Pill bugs do not prefer dirt or no dirt. List of Materials: -Dirt -10 Pill bugs -Choice Chambers -water -filter paper -brush -timer Procedure:

approach your problem using scientific methodology—developing a question‚ an hypothesis‚ an experiment‚ and a control for the experiment. Let’s share this assignment. I will supply both the initial question and the experiment we’ll perform on you. Your job is to state the hypothesis and to design the most important and most basic control for this experiment: Your Question: What’s my problem? Is it ADD or is it ADT?

There are different steps to the scientific method and the most important thing is to make a hypothesis to whatever you are testing in the experiment. (2) You can ask questions if you need to and begin gathering your facts and all your materials you have come up with.

In order to understand‚ there must be experiments to prove whether a hypothesis is correct or incorrect.To prove whether a hypothesis is correct there must be physical evidence. In this lab will be looking at the different scientific paradigms to see if they are correct. In this lab we conducted a scientific test of astrological predictions‚ test for psychic
