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

In this lesson, students will work in pairs using the 3Doodler to doodle objects related to the winter season. Students will doodle these objects in different sizes and weights. The challenge will be for students to balance their objects, considering their varying weights and sizes.

Lesson Plan

Instructions

Step 1 - PREPARATION

If students have not previously played with a counterbalance scale, have them do so now.
Have students play around with balancing objects of different sizes and weights on the scale.
*This can be done as a small center activity.

Follow the directions below to create your own Doodle-Winter-Balance Mobile so that you can share an example with the students.

Step 2

Call students to the whole group. Have them brainstorm objects related to winter, e.g., skates, mittens, hot chocolate, snowman, sled, boots, Santa, holiday tree, etc. Chart their responses on the board.

Step 3

Share the goal: Project your tablet or computer screen on the board for students to view the Doodle-Winter Balance Stencils. Explain that they will need to create stencils for 3 different objects of different sizes and weights, which they will later balance on a mobile. Show students the mobile you created. Note how the objects are dispersed for balance.

Step 4

Share the challenge: Students may use no more than 1 stick of plastic on their small doodles, 2 sticks of plastic on their medium doodle and 3 sticks of plastic on their large doodle. Ask students which doodled objects will be the heaviest? Why?

Step 5

Prompt students to make predictions about what will happen.

*The largest object will need to be counterbalanced by a combination of smaller or medium-sized objects.

Step 6

Use the Doodle-Winter Balance Stencils to model how to draw and doodle each object, outlining first and then filling. Students should attempt to use the total stick requirement for each doodle, or as close to it as possible when doodling. It may be easier to doodle each object a solid color to keep track of how much plastic is used.

Step 7

Divide students into pairs. Hand out the Doodle-Winter Balance Stencils and the 3Doodlers. Instruct students to select winter-objects from the brainstormed chart created earlier.

Step 8

Instruct students to doodle a loop on top of each doodle, so it can be hung later.

Step 9

After students have completed their doodles. Model how to create a mobile using string, tape, straw and a bull clip.

*Depending on the level of the students, you may determine the criteria, e.g., balancing all objects or just a selected number.

Wrap Up

Have the students share their Doodle-Balance-Mobiles. Ask students which objects were the heaviest? Lightest? Why? How were they able to balance them? How can we make smaller objects weigh more? Explain. Share students' Doodle-Balance-Mobiles on Twitter. #3DoodlerEDU @3Doodler

Assessment

The teacher will assess the students by evaluating their Doodle-Balance-Mobiles, as well as their contributions during partner work and group discussions.

Possible Extensions

Students will experiment with altering the weights of each doodled object by adding more plastic to each doodle. They can also add craft items like gems or rhinestones, which can be welded to their doodles with plastic. Challenge them to make smaller objects weigh more than larger objects. Have them balance new objects on the mobile and discuss the results.

• balance - an even distribution of weight enabling someone or something to remain upright and steady.

• collaboration - to work jointly with others or together especially in an intellectual endeavor.

• design - to prepare the preliminary sketch or the plans (for a work to be executed), especially to plan the form and structure of an object, building, bridge, etc...

• measure - ascertain the size, amount, or degree of (something) by using an instrument or device marked in standard units or by comparing it with an object of known size.

• problem-solving - the process or act of finding a solution to a problem.

• STEM - science, technology, engineering, and mathematics, considered as a group of academic or career fields.

• weights - a heavy object, especially one being lifted or carried.

• winter - the coldest season of the year, in the northern hemisphere from December to February and in the southern hemisphere from June to August.
