bag works similar to a membrane in certain situations. Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and they will both absorb relatively similar amounts of water. Procedure: Variables: Controlled- water and size of potatoes. Manipulated variables- potatoes growth based on

Title: Penny Lab Experiment By -Objectives To determine how soap affects the surface tension of water. -Hypothesis In this experiment the hypothesis was that soap was going to affect the surface tension by weakening the bonds and allowing less water on the penny. -Materials * Penny * Beaker x2 (One containing soapy water the other containing pure tap) * Paper towels * Lab review sheet * Pencil * Pipette -Procedure First we picked who would drop the water onto

direct relationship and similarity between standing height in centimeters and leg length in centimeters. Therefore‚ our hypothesis was‚ if leg length increases‚ then standing height will also increase. 1) The steps for the scientific method are: • An observation is made • A question is asked • An tentative answer is posed‚ in the form of a hypothesis • “if….then” method • The prediction can be tested by experiments or additional observation The name of

Notes The ultimate goal of theory evaluation is to determine the potential of the theory to scientific knowledge. Hardy • Theory evaluation: o meaningful and logical adequacy o Operational and empirical adequacy o Testability o Generality o Contribution to understanding o Predictability o Pragmatic adequacy Logical adequacy (diagramming) - identifying all theoretical terms (concepts‚ constructs‚ operational definitions‚ referents). Theory is a set of interrelated concepts and statements

Hypothesis: For my hypothesis I wrote‚ "If the pill bugs are in the petri dish with the other chemicals then they will go to the filter paper where the sugar is more so then the other filter paper that has chemicals on it". I choose this hypothesis for many reasons. First off‚ I know that most organisms‚ bugs‚ insects‚ etc… like sweet and sugary tasting things. I know this

do? What do biologists do? Biologists study many things. The three main things that they do are that they hypothesis‚ they make observations‚ inferences and they record data. Without hypothesizing‚ biologists can not experiment or create scientific laws. Being able to hypothesis is very important in the world of science. Some evidence that I have‚ to prove that biologists hypothesis‚ are the activities we did in page 17 and in page 28. In page 17‚ in our notebook‚ we did an experiment on

question or problem statement. Problem Statement: How do different ambient temperatures affect the rate of body cooling? 2. Predict a solution to the problem or an answer to the question. This will be in the form of a hypothesis. This solution design or hypothesis should be based on previously obtained knowledge or research and should be supported by scientific evidence. Identify the independent and dependent variables. The independent variable is the variable that is varied or manipulated

starting point of most new research is to formulate a general question about an area of research and begin the process of defining it.This initial question can be very broad‚ as the later research‚ observation and narrowing down will hone it into a hypothesis. For example‚ a broad question might ask ’whether fish stocks in the North Atlantic are declining or not ’‚ based upon general observations about smaller yields of fish across the whole area. Reviewing previous research will allow a general overview
