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 HELP!!! I WILL BE AFTER TUESDAY (5/31), WEDNESDAY (6/1), THURSDAY (6/2), MONDAY (6/6) TOPIC A: Scientific Method 1) What are the 5 steps of the scientific method? 2) Define Control and Variable True/False _______1. _______2. _______3. _______4. _______5. 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. PRACTICE: SCIENTIFIC METHOD 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? Slimotosis 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 B: Metric Conversions What are the prefixes for the metric system? What are the basic units (3 of them) With each jump between prefixes in the metric system, the amount changes by an order of ___________________. (How much do you multiply or divide by in one step) For the following things answer with the correct measurements (meter, liter or gram) mass of a penny length of a football field amount of air in a basketball density of a marble use a graduated cylinder to measure this use a triple beam balance to measure this PRACTICE: METRICS 456 m = _____________________ mm 675.69 km = ___________________ mm 345 kl = ________________________ml 957.95 mg = _____________________ kg TOPIC C: States of Matter For the following things give the proper state of matter (solid, liquid, gas) CO2 H20 Sugar metal steam Fixed Shape and Fixed Volume No Fixed shape No fixed shape and no fixed volume Gases have all of the following properties except: a.

Stays the same d. Explodes As temperature goes up, volume: a. Goes down b. Goes up c. Stays the same d. Explodes The unit for temperature in gas laws equations is: a. Farenheit b. Celcius c. Kelvin TOPIC D: Energy and Energy Transformations Energy What is Kinetic Energy? What is Potential Energy? How are they calculated? (What are the equations?) What variables are used, how are they determined, what units to you use for each? Be able to do a series of word problems (like on your practice sheets and quiz sheet) What is weight, and how is it different from mass? What are the units for weight? What are the units for energy? Energy Transformations What is an energy transformation? What are some types of Kinetic Energy What are some types of Potential Energy What are the 2 laws of energy? Be able to show the flow of energy transformations for any given real world situation. TOPIC E: Kinematics What is kinematics? What are the 5 variables we use in 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. PRACTICE: KINEMATIC EQUATION WORD PROBLEMS 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. PRACTICE: INTERPRETING GRAPHS 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. 15 D d (m) C 10 E B 5 A 5 10 15 20 t (sec) Directions: Based on question, answers require a specific interval (Letter), distance, velocity, or time. 1) _____During which interval did Ryan have positive acceleration? 2) _____How long was Ryan at rest during the interval? 3) _____What interval did Ryan have negative velocity? 4) _____At what time did Ryan get hit by the truck? 5) _____How far did Ryan fly when he got hit by the truck? 6) _____During what interval did Ryan have positive velocity, and zero acceleration? 7) _____How long was Ryan moving forward throughout the entire scenario? 8) _____At what time did Ryan hit the ground? 9) _____How fast was Ryan cruising during interval A? 10) Draw a line on the graph that you could use to approximate Ryan’s velocity at 9 seconds. 11) Put a star on the graph where Ryan had the highest velocity. 12) Put a title on the graph.
