Forces Affecting Objects: Science Tasks with Otis & Flask

This booklet consists of three centers and their associated readings and assessments.
Center 1 Ramp Rolling/Gravity & Collision involves observing the effect of the
non-contact force of gravity and the contact force of collision on the
motion of a toy car when rolled down a ramp.
Center 2 Get Pushy examines the impact of a push on the toy car as it rolls down the ramp.
Center 3 Magnetic Fishing explores how magnetism can be both a contact and noncontact force. This Center also includes a Final Assessment that the teacher will use to check students understanding from all three centers.

You can download each center separately, or order ALL the center books in a great storage box for only $24.99 at:

Science Tasks with Otis & Flask were designed as centers to reinforce science concepts in grades 3-6. These centers include Teacher Background information, Task Cards for each center that provide information for the student, photocopy-ready student packet pages which many include student observation sheets, data sheets, student readings, vocabulary, and assessment items. An answer key is also included.

The Teacher Guide for all the centers is available as a FREE download. This gives detailed information about the set-up of each center, and content addressed in each center as well.
