Final Review: Integrated Science

Final Review: Integrated Science
How to Study for the Final: First go through this study guide to get an idea of what will be on the final.
Answer any questions, fill out any definitions, and do any problems that are listed. We have taken example
problems from your quizzes, tests, and labs to give you SOME practice. However, you will likely need more
practice in some areas. If you need more practice you should refer to the hard copy of your tests/quizzes, as well
as you labs and notes. If you do not have these, almost everything that we have done in class can be accessed
electronically from my website. PLEASE MAKE TIME TO COME AFTER SCHOOL IF YOU NEED
TOPIC A: Scientific Method
1) What are the 5 steps of the scientific method?
2) Define Control and Variable
The first step of the scientific method is to identify the problem.
An experiment should test many variables at the same time.
A hypothesis is your prediction for how an experiment will turn out.
The metric unit for measuring mass is grams.
The metric unit for measuring length is inches.
Patty Power
Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production
of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He
has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just
like new sauce but is really just mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that
would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems
and 8 customers in group B reported having fewer gas problems.
Which people are in the control group?
Which people are the treatment group?
What should Mr. Krabs’ conclusion be?
Why do you think 8 people in group B reported feeling better?
Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell
develops a nasty slime and gives off a horrible odor. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure,
while Sandy says that drinking Dr. Kelp will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with seaweed for 1
week and having him drink Dr. Kelp. After a week of treatment, the slime is gone and Gary’s shell smells better.
What was the initial observation?
What is the control?
What is the treatment?
What should Sponge Bob’s conclusion be?

TOPIC E: Kinematics

Given a particular word problem, you need to determine what variables are present, and figure out how
to solve for the other variables not present using your formula sheet.
Know how to pick the appropriate equation from your equation sheet given a problem
Directions: Use the information below and your kinematics equations sheet to find the 2 missing variables for
each interval (A, B, C…). Remember D= Displacement, NOT DISTANCE. Show your work below each
description to find the 2 missing variables and fill your answers in the chart below.
Scenario: Mr. Bell thinks he is King Shiz on the streets, and is a master rollerblader (not the kind where you do
tricks, but the kind where you have a headband, tights, and a walkman). This is the story of his unfortunate
rollerblading incident.
Mr. Bell was getting ready to cruise down the boardwalk in his sweet rollerblades, wearing his favorite neon
green singlet, matching headband, and his tape player, stocked with smooth jazz by Kenny G.
Interval Information:
A: He starts from rest and begins to accelerate at 2.5m/s2 for 8 seconds.
B: Then Mr. Bell sees that he is over the rollerblading speed limit and slows down to 14 m/s in 2 seconds.
(Hint: you might need to use the final velocity of your previous situation as your initial in this situation and
subsequent situations!)
C: Then he cruises at a constant velocity(this tells you a relationship about initial and final velocity). He then
maintains his velocity for 10 seconds.
D: He then slows down for 5 seconds to avoid hitting Snooki who is “trying to find the beach”, but instantly
comes to a complete stop when he runs into the formidable Snooki as she drops him cold with a closeline.
Know how to find initial, average, and final velocity.
Given a graph of either time vs distance, time vs velocity, or time vs acceleration, be able to get
information about the other variables from these graphs.
o What does the slope on a T vs D graph tell us?
o What does the slope on a T vs V graph tell us?
o What does the slope on a T vs A graph tell us?
o What does the concavity on a T v D graph tell us?
o What does the concavity on a T v V graph tell us?
Make sure you understand what is happening in a free fall situation.
Make sure you can set up a problem where a ball is tossed in the air and falls back down.
Scenario: The graph above describes an unfortunate situation. Ryan was very excited because he got a brand
new Schwin bicycle for his 17th birthday, complete with a horn and a basket. He named his bike Flash. Ryan
was riding Flash down the street a cruising speed until he came to a red light. He stopped at first, but then
decided to gun it, at which point he was hit by an 18 wheeler and was thrown off his bike backwards flipping
through the air, until he came to rest when he hit the ground. Ryan got up and the only thing that was hurt was
his pride, and his prized possession, Flash. Don’t run redlights Ryan.
