  1. Average Speed Chuck Faber, Christopher Adame, Krissy Hopper, and Bridget Gengler

  2. Eight grade standard 1 c. Students know now to solve problems involving time, distance and average speed.

  3. Vocab Review Do-NOW! In your notebook answer these questions….. • How far did you walk from the doorway to your seat? • How long did it take you to walk the distance? • What do you think your average speed was? Distance: measurement of how far apart objects are. Time: measurement of duration How long? Average speed: total distance per unit of time. s=d/t

  4. Class Demo? Pick a volunteer from the class to walk from their desk to the door. Have class makes predictions on how fast he/she will travel (average speed). Measure and time the walk. As a class determine the average speed.

  5. Group work! Have students get into their lab groups (about 4 students). Students work on a computer simulation of a runner on average speed. Each group must complete one worksheet. Review theirs answers as a class.

  6. Formulas Classwork • Pass out time, distance and speed worksheets. • Work in pairs. • Teacher should model how to approach these problems. • What is given? • What do you need? • What is not finished is HW! S= d/t How can you find distance? D=s*t How can you solve for time? T=d/s

  7. Average Speed Lab • Pass out worksheets at end of class explaining lab. • Have each group assign a measurer, timer, roller, and catcher. • Explain each job and their duties. • Have students prep their science notebooks for the lab. • Write title, etc.

  8. Exit Ticket Design two original time, distance or speed problems. Trade your problems with another group. Answer their problems. Label who created and who solved. Turn in
