Section 1: Scientific Process
1. In designing an experiment, how many dependent/manipulated variables should be tested?
2.
What is the purpose of a control set-up when designing an experiment?
3.
What are the three goals of science?



4.
What is the difference between qualitative and quantitative observations?
5.
“The Isopod has 2 antennae” is an example of which type of observation?
6.
The “Problem” in an experiment is written in what type of sentence form?
7.
A ______________________ is a possible solution to a problem which can be tested.
Use the following scenario to answer questions 8-10
Homer Simpson notices that his shower is covered in a strange green slime. Marge suggests that Homer use their normal Itchy
& Scratchy cleaner. After reading an article in a magazine that stated coconuts have a special cleansing ability his friend
Barney tells him that coconut juice will get rid of the green slime. Homer likes Barneys idea better.
8.
Formulate a hypothesis for Homer’s preference.
9.
How could Homer & Barney test your hypothesis?
10. Identify the variables in your proposed experiment. Identify the control in your proposed experiment.

Section 2: Reading Tables and Graphs
Use the following scenario & graph to answer questions 1-5
Bacteria are tiny microorganisms that can reproduce by dividing into two. The
graph shows the results of an experiment on the effect of temperature on
bacterial reproduction. At the beginning, three populations of bacteria, all of the
same type, were of equal size. Each population was kept at a different
temperature for 4 days.
1.
Classifying What variable did the researcher change during this
experiment?
2.
Inferring What do the shapes of the curves tell you about the changes in population size?
3.
Calculating For the bacteria kept at 15°C, how much did population size change during the experiment?
4.
Drawing Conclusions What effect did the different temperatures have on the growth of the bacterial populations?
5.
Predicting Suppose some bacteria used in this experiment were kept at a temperature of 100°C (the temperature of
boiling water). Would you expect the population sizes to increase even faster than at 15°C? Explain your reasoning
Section 3: Chemistry/Biochemistry
1. What are the 3 sub-atomic particles that make up an atom (the exception being Hydrogen)? What are their charges?
2.

3.
What types of foods are high in lipids? What are the major roles of lipids in living organisms?
4.
What types of foods are high in proteins? What are the major roles of proteins in living organisms?
5.
What types of foods are high in carbohydrates? What are the major roles of carbohydrates in living organisms?
6.

What substance in the mitochondria carries usable energy (What is the goal of cellular respiration? To make….)?
3.
What are the reactants of cellular respiration? What are the products of cellular respiration?
4.
What is the relationship between cellular respiration and photosynthesis?
5.
Explain what is happening to a distance swimmer who is no longer able to swim as fast as at the beginning of the race
and is feeling a burning sensation in her legs.
6.
Photosynthesis converts _____________________ energy into _____________________ energy, while cellular
respiration takes the ______________________ energy and converts it into ______________________ energy.
7.
Photosynthesis occurs in the _______________________ of the cell. Cellular Respiration occurs in the
______________________ of the cell.
