Using what Christopher and Kate have already observed‚ suggest a possible hypothesis regarding how the mass of a rock changes when placed in water. Identify the independent and dependent variables. 3. Describe‚ in detail‚ a procedure to test your hypothesis. Identify the controlled variables. Scenario 2 Lizzie loves to stargaze at night.

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

hand‚ in their mind and come up with a conclusion of what occurred. Also I believe that the mindset is one that can be taught through training and experience. 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

TABLE OF CONTENTS Abstract Hypothesis Procedure Observation Analysis concusion Abstract An experiment was conducted to learn and demonstrate the steps involved in the scientific method. The steps of the scientific method were used to identify six substances that were labeled “unknown.” The substances were put through a series of tests an observations to determine their identities. Hypotheses The identities of the unknown substances are as follows: Substance #1 – Plant
