1. Chapter 1: Honors Science Stations Review Kawameeh Middle School 8 th Grade

2. Station 1 Starting at the North East corner of your table measure 52 centimeters toward the window and then turn 90 degrees toward the back of the room and measure 42 centimeters. (show all work!) ▫Measure the displacement ▫Calculate the displacement ▫Calculate the distance

3. Station 2 Start your block at the zero centimeter mark on the meter stick. Have one group member start the stop watch as another group member moves it 70 centimeters left, 32 centimeters right and then 12 more centimeters to the left. Stop the watch when you make your last move. ▫Using the amount of time it took to complete the steps above calculate average speed and average velocity. ▫Describe the position of the block in its new location.

4. Station 3 From the starting point to the end of the board is 1 meter long. Calculate the speed in which the ball rolls by calculating the time first for three different trials (trial 1 = 1 textbook, trial 2 = 2 textbooks and trial 3= 3 textbooks). Calculate the speed of each trial and identify which was the fastest. Make sure to set up the data table in your notes that you see below. Trial (different heights) DistanceTime (s) Speed (m/s) 1 textbook1 meter 2 textbooks1 meter 3 textbooks1 meter

5. Station 4 Quietly take your group into the hallway and find the starting point. Note that from start to end you will travel 10 meters. One person will complete three different tasks (walking forward, walking backward and hopping on one leg) while the other person is calculating the time it takes to travel each distance. Calculate the speed of each trial and identify which trial was the fastest. Identify two ways we can increase speed. TaskDist.TimeSpeed Walking forward 10 m Walking backward 10 m Hopping on one leg 10 m

6. Station 5 Use the graph on the right to answer questions 1-3. 1.What is the acceleration between 0.0s and 2.0s? 2.What is the acceleration between 2.0s and 5.0s? 3.What is the acceleration between 6.0s and 7.0s? Use the graph on the left to answer questions 4-5. 4. During which part of the journey was the bus moving fastest? 5. During which part of the journey did the bus have the greatest acceleration?

7. Station 6 1.Determine the velocity for the time interval of t=0s to t=2s. 2.Determine the velocity for the time interval of t=4s to t=6s. 3.Determine the average velocity for the time interval of t=0s to t=6s. 4.What is the total distance traveled? 5.What is the total displacement? 0 1 2 3 4 5 6 7 024681012 Time (s) Position (m)

8. Station 7 1. During a race, a sprinter increases from 5.0m/s to 7.5m/s over a period of 1.25 seconds. What is the sprinters acceleration during this period of time? 2. Marisa’s car accelerates at an average rate of 2.6m/s 2. Calculate how long it takes her car to accelerate from 24.6m/s to 26.8m/s. 3. The fastest of all fishes is the sailfish. If a sailfish accelerates at a rate of 14km/h 2 for 4.7 seconds with an initial velocity of 42 km/h, what is its final velocity? 4. A cheetah travels a distance of 50 miles in 1.5 hours. If the cheetah runs with an acceleration of 2 miles/hr 2, and reaches a final velocity of 60 mi/hr, what is the cheetah’s initial velocity?
