Balance & Motion
Investigation 2
Part 2
Zoomers
Students use the plastic disks from the previous lesson, and lengths of string, to make "Zoomers".
3. Lesson set up and Management
Systems Approach: Identify the parts of a system, how the parts go together, and how they depend on each other. (ST01, STI02, STI03, & STI04)
There are different ways to initiate rotational motion.
The motion of an object can be changed by pushing or pulling.
Tops and Zoomers both spin, but in different ways.
3. Lesson set up and Management
Materials:
Per student:
1 Large Plastic Disk
1 String, 100 –115 cm long
1 Student Sheet called Zoomer
Per classroom:
1 jump rope
Student Management:
Some students have a hard time tying the knot on their string. Use the demonstration knot tying sheet!
Some students have a hard time winding up their Zoomers and letting them go SLOWLY. It is helpful if the teacher stands behind those students that are having difficulty and guides their hands.
It is helpful if another adult is in the room.
Pay attention to the optional Zoomer accessories in the teacher’s guide. The small disks or pencils help prevent student’s fingers from getting pinched.
Have students with long hair pull their hair out of the way.
Writing Support:
Have students draw their Zoomers in their science notebooks, and answer the following question below their drawings, “How do you think Zoomers are like the tops?”
Reading Support:
None for this lesson.
