Table leaders will equally assign sections of the text below (1-min). Each member of your group will then read and annotate their section of the text in silent mode (3-min). Readers must make notes (text tool) and underline content to help them restate the main information during their share time. After the 3-min bell, each member will take turns sharing the content with the other group members (1-min share time each student). (7-min total
Materials:
(4) of the same type of book, Newton scale, string to pull books, smooth & clutter free table top, calculator.
(Each line on the Newton scale) = .5 Newtons

What is your Hypothesis? (If/Then statement)
Procedure:
1) Place a loop of string inside a textbook (inside the cover) and hook a Newton scale to the string.
2) Pull the book across the table with a smooth steady pulling motion.
3) In the middle of the (constant speed) pulling motion read the force on the Newton scale. Record force in data table
4) Repeat test for a total of 3 trials. Calculate the Average pulling force (T1 + T2 + T3 รท 3).
5) Repeat steps 2, 3, & 4 with 2 books, then 3 books, then 4 books (stack books).
6) Help...review the video example above
