Study Guide for Body Works part 1 unit test. 

Hi students - change in plans.  Just got out of meetings with other teachers at 3:55.  Postponing the plan to have you log in to Google classroom, until tomorrow.  

Consider all text below to be black, even if it looks gray. Please answer all questions in this first group of questions for your Study Guide: 

Name___________________________                   Date _________

SPS/  Body Works Study Guide , part 1.

   1.    What is the primary purpose of making observations?

 a.    Making predictions

 b.    Putting together facts

 c.    Reaching conclusions that don’t need a factual basis (opinions, like best color)

 d.    Gathering data.

  2.    For this question, circle one from each letter – THIS IS NOT A MULTIPLE CHOICE QUESTION, IT IS FOUR   QUESTIONS)               

   A well-designed experiment includes:

     a.       No control group or a control group (circle one )

     b.       Small sample size or large sample size (circle one )

     c.       Procedures that others can recreate & repeat……or not reproducible (circle one )

     d.       One trial only……or  multiple trials (circle one )

   3.    What is a variable?  Define:

   4.     What are the 3 types of variables discussed in class? Name them.

a.    ______________  (memory trick for this one is:  Change)

b.    ______________ (memory trick for this one is:  Result you measure)

c.    ______________ (memory trick for this one is:  Stays the Same)

   5.    What would be an example of the three types of variables? Natalie invented a new plant fertilizer. She wants to run an experiment to show how well it works.  Natalie sets up 200 planters. Natalie used the same type of seed, soil, and planters, and the same amount of soil, water, air and light to each plant, keeping all plants at the same temperature.   She gave 100 of the plants no fertilizer, and she gave fertilizer to 100.  After 4 weeks, she measured and recorded the height of each plant.  Underline each of the variables,then list them below by type.  Also, state the memory trick discussed in class for some types of variable:

   a.    Independent -                            - Why is it important to only have one?

   b.    dependent -

   c.    controlled (or constant) - 

  6.    Write a hypothesis for Natalie’s experiment: ___________________

___________________________________________________________.

  7.    What was the cause of Pellagra found by Dr. Goldberger? 

  8.    Write a hypothesis for Dr. Goldberger’s experiment.

  9. Explain how Dr. Goldberger limited the variables to find the real cause of pellagra.  Why was this important?

  10. What was the biggest problem with Dr. Goldberger’s experiment?

a.    No control group (in other words, no group that got a good diet)

b.    Small sample size (only about 12 orphans)

c.    Procedures that are not reproducible

  11. How could Dr. Goldberger have increased the sample size of his experiment?
