### 3Doodled Tops (Force & Motion)

Time Required: Two 45-60 minute sessions
Skill Level: Intermediate

In this activity, students will work in pairs to design and construct a top with a 3Doodler. A top must spin for, at least, 10 seconds within a 30. x 30 cm. space before dropping. Students will test and retest their designs to make adjustments before entering a class competition.

The top that spins the longest amount of time over three attempts is the winner!

### Lesson Plan

Step 1

#### Wrap Up

Students share their top designs and the process. Students review the tops of other pairs and offer feedback. Students compete with tops and record their top's time over 3 attempts. The highest recorded time total wins. Students research the Gyroscope effect, potential and kinetic energy,

#### Assessment

Evaluate students' assessments of their design-build-test cyclic process.

#### Possible Extensions

Students write an informative paper about how engineering is part of the top industry. Students design a throwing top using 3Doodler, recycled materials and string.

Questions:

1. What was the most challenging part of designing a top?

2. What was something interesting that you learned during the process?

3. Did you need to make any changes to your group's original design? Explain.

4. Were there any materials that we did not have in our classroom that would have improved the design and effectiveness of your top? If so, please, share.

4. What did you observe other groups doing that you'd like to try next time?

5. How did you overcome difficulties during the process?

6. Share a mistake you made and how you learned from it.

7. Observe and describe how your top looked shortly before it fell.

8. What were some things that your group did well when working together?

9. What are some things you could do next time to work together better?

10. How do friction and gravity affect your top? Explain.

Top-Tops

Twirling top - A twirling top is spun by manually twisting the crown.
A dreidel is a common example of a twirling top.

Supported top – A top which is spun with a string while the top is held upright by a support.

Whip top - A whip top is set into motion and kept spinning by whipping it with a whip.

Throwing top - A throwing top has a string wrapped around its body which is attached to a stick. When the top is thrown causing the string to be rapidly released from its body, the top spins.

Pump top - A pump top has a crown that is pushed down or pumped several times to create the spin.

#### Vocabulary

• gyroscopic effect - the difficulty to change a spinning object's axis of rotation due to forces of physics.

• kinetic energy - energy of an object in motion, due to motion.

• potential energy - the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

• torque - a twisting force.

#### Educational Standards

Common Core
CCSS.ELA-LITERACY.SL.4.1

Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 4 topics and texts, building on others' ideas and expressing their own clearly.

In This Lesson

Students will work in small groups to brainstorm, design and create a top.

Common Core
CCSS.ELA-LITERACY.SL.4.1.C

Pose and respond to specific questions to clarify or follow up on information, and make comments that contribute to the discussion and link to the remarks of others.

In This Lesson

Each group must respond to questions to clarify or follow up on information about the process of designing a topt. Students must ask specific and relevant questions about other group's tops.

Common Core
CCSS.MATH.CONTENT.4.MD.A.1

Solve problems involving measurement

In This Lesson

Students will use measurement to design tops and to keep the top within the measured testing area, i.e., 30 x 30 cm.

Next Gen Science
3-5-ETS1-1

Engineering Design Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

In This Lesson

Students will recognize the goal/problem of this task and meet specified criteria to solve this problem.

Next Gen Science
3-5-ETS1-2

Engineering Design Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

In This Lesson

Students will consider various designs, test and make adjustments to solve a problem, i.e., create the longest spinning top.

Next Gen Science
3-5-ETS1-3

Engineering Design Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

In This Lesson

Students will test their tops and make adjustments to identify aspects of design that can improve the duration of the spin.

CS Teachers
1A-A-5-3

Plan and create a design document to illustrate thoughts, ideas, and stories in a sequential (step-by-step) manner (e.g., story map, storyboard, sequential graphic organizer).

In This Lesson

Students will brainstorm ideas and sketch a design to illustrate their group's thoughts and ideas.

CS Teachers
1A-A-3-5

Decompose (break down) a larger problem into smaller sub-problems with teacher guidance or independently.

In This Lesson

Students will break down the process into brainstorming, designing, building, testing, presenting to group.

ISTE
1C
