Study guide covering experimental design: hypotheses, variables, controls, constants, validity, data representation, and scientific tools.

Aug 25, 2014 · Fundamentals of Experimental Design What is measured during a controlled experiment? Why? Working in the science lab can be a lot of fun. Mixing random chemicals and burning stuff just to see what happens can be entertaining (and possibly dangerous), but it doesn't lead to anything helpful to the scientific community.

Look at the table below and answer the questions which follow concerning the student’s experiment. 1. From the experiment above, what was the independent variable? 2. From the experiment above, what was the dependent variable? 3. What conclusions can be drawn from this data? 4. What further experiments can be developed using this data as a guide?

Question: Exercise 3-1. Based on the experimental design shown in Figure 3-1 and Equations 3-1 - 3-4, answer the following questions. 1. As the ball flies through the air along the dashed arc, what is accelerating it? 2. Is the acceleration in the X - …

hypothesis to explain this behavior and design an experiment to test the hypothesis. A number of rats are divided into two groups: One group is fed a normal diet whereas the other group is fed the same diet but with one necessary mineral left out. The animals receiving the normal diet remained healthy; those in the other group grew weaker.

ANSWER KEY Experimental Design Scenarios Instructions: After reading through each scenario identify the variables within the experiment. Scenario 1: Miracle-Gro and Basil John really likes the herb basil. He likes it so much he eats it faster than it grows in the 8 pots he has on his window sill. John decided he needed to find a way to make the ...
