Integrated Engineering Lesson:
My Little Play Dough Engineers

Engage: Day 2
Identify Problem
Analysis Level
– The student’s knowledge is analyzed by conducting tests and engineering a solution.

Evaluation Level
– The evaluation is the engineering report, which concludes the engineering design process.

Creating Level
– Designing the optimal form of play dough for a client by using the engineering process.

Formative Assessment
– Completing the lab

Engineer - Day 3
Ask New Questions, Identify Problem, & Repeat Process:
Send the teams back to find one more recipe to test.
Test & revise again
Share results about the end product
Demonstrate the product with cookie cutters.
Take pictures or draw pictures for the engineering report.
Write about why their product is the best.

1. Introduction to engineering.

Grade Level: Second

Duration: Three to Four Days

- Physical Science
Structure and Properties of Matter
- Engineering, Technology, and Applications of Science

Common Core
- ELA on writing and speaking
Divide the students into groups of three or four.

Go over the worksheets and process.

Brainstorm Solution:
Limited ingredients and tools to work with.

Test Idea & Revise:
6. Request a recipe and ask teacher for ingredients.
7. Create a hypothesis, test, record results, and re-test.
8. Each play dough test should be stored in zip lock bags and labeled with the trial number.

Students should have several ideas on what to do with the products.
Gently give suggestions.
Example: Give it to the kindergarten classes.
Perhaps help the younger students practice their letters and numbers with the play dough
Share Results:

After the students have worked with their first recipe gather them together for a group discussion.
Remind students about taking turns to talk and listen.
Use a talking object to help them.

Each group should share their initial products without revealing how it was made to prevent copying.

Procedures, but not ingredients, and issues can be discussed.

Knowledge Level
– What is a mixture?

Comprehension Level
– Briefly describe what a chemical engineer does and give one example of what they create.

- Briefly describe the engineering process.

Application Level
– The student’s knowledge is applied through the lab

2. Display every day items created by chemical engineers, but do not tell them that.

3. Have the students pair share and discuss what the items have in common then share with the class.

4. Reveal what the items mean.

5. Tell them they will be playing the part of chemical engineers.

6. Introduce the book "Somebody and the Three Blairs" by Marilyn Tolhurst

- The students will learn the concept of “just right.”
- The students will need to understand this concept to find the “just right”
recipe for play dough.

Previous Knowledge Needed:
- The
scientific process

- The
engineering process

or you could
make it a mini lesson

Pass around store bought play dough
Present the problem
Teacher is the project manager & students are the
chemical engineers
Brainstorm Solutions
of solids and liquids
Make play dough and tell the students it is a
Talk about the properties
Ask how the students could improve the process.
Change the amount of the ingredients?
Change the order of the steps?
Ask what possible problems they may run into.

The play dough is non-toxic, but it should not be eaten.

Order and clean-up.
