Hypothesis Using your background research and current knowledge‚ make an educated guess that answers your question. Your hypothesis should be a simple statement that expresses what you think will happen. Experiment Create a step by step procedure and conduct an experiment that tests your hypothesis. The experiment should be a fair test that changes only one variable at a time while keeping everything

Two groups of this species will be used‚ flies with normal wings and flies with vestigial wings. This experiment is going to test the hypothesis that there will be more number of flies with normal wings at the food site than the number of vestigial wings. Materials’ List: - A vial of flies with vestigial wings. - A vial of flies with normal wings. - A plastic box with holes on two

What are the advantages of using a circuit with a GFI detector when completing a physics lab that uses hot water? (2 points) The advantages of using a circuit with a GFI detector when completing a physics lab that uses hot water is that it prevents you from getting shocked. If part of your body were to be touching water or the ground

method? Who uses the scientific method and why are we interested in using the scientific method? First off the scientific method is a procedure consisting of systematic observation‚ measurement‚ experiment‚ formulation‚ testing‚ and modification of a hypothesis. Everyone from scientist‚ mathematicians and even you can use the scientific method. We are interested in using the scientific method because we can solve problems or answer scientific questions. The first step in the scientific method is making

claimed that the truth of a hypothesis can never be confirmed. A hypothesis is an “if-then” statement‚ which that is an assumption of causality. A basic example of a hypothesis is “If somebody jaywalks‚ then others will too”. To confirm this hypothesis of human psychology and the causality of one person jaywalking leading to others jaywalking‚ one would have to observe the reaction of the other subjects to the original jaywalker. On a more general note‚ for a hypothesis to be tested and confirmed

The scientific method is a systematic approach of observation‚ hypothesis formation‚ hypothesis testing and hypothesis evaluation that forms the basis for modern science. There are anywhere from five to eight steps in the scientific method. However‚ all versions of the scientific method involve the person trying to solve the problem experimenting

Develop a Hypothesis: My hypothesis is that the venue serves a broad range of people who are interested in non-local newspapers and magazines‚ in local newspapers and magazines‚ or in picking up a beverage or other sundries. My hypothesis is based on the following observations: there are many newspapers and magazines in several different languages on display outside the venue;

Kaitlyn Swearingen Effects of the Pigmentation of an Onion Cell within 40% Ethanol and Deionized Water Purpose: To measure the amount of pigment in a solution of 40% ethanol and deionized water both containing pieces of an onion with a spectrometer. Hypothesis: 40% ethanol breaks down the cell creating less surface area and spreading out the pigment while the deionized water absorbs the pigment in a greater surface area. Procedure: Add 10ml of deionized water and 40% ethanol to a 6-dram vial Add 6g of
