Lesson Plan

Yeast Breads

This lesson is designed to learn the function and purpose or yeast in grain recipes. Students will work hands on in the kitchen gaining experience working with yeast as they experiment and prepare soft pretzels. They will demonstrate the process of fermen
Objectives

Students will be able to...

  • Discuss the purpose and function of yeast.
  • Demonstrate the process of fermentation, kneading, proofing, and shaping.
  • Innovate given recipes by adding their own twist.

1 Introduction/Anticipatory Set

Activity: Reading

Day 1: Materials needed:

-Yeast in Ziploc

A picture/or baggie of yeast will be hanging in the front of the classroom.
The Ziploc will be labeled ”What is this and what is its purpose?” This will get the students interested in what we will be covering the next couple of days.  

Day 2:

Handout pretzel recipe and pretzel lab procedure evaluation.

Student Instructions

Day 1:

 A picture of yeast will be hanging in the front of the room labeled “What is this and what is its purpose?” This will get the students interested in what we will be covering the next couple of days.  

Day 2: Students will receive their recipe and pretzel lab procedure evaluation. This will allow students to read through directions before the lab is conducted. 

2 Instructional Activities

Day 1:

Materials needed:

-Yeast in Ziploc

-URL: Kahoot.it.com

-Yeast, pop bottle, sugar, warm water, and a balloon for the experiment

Students will participate in a class discussion using a device accessing the website kahoot.it.com. This will allow students to answer anonymously and provide their thoughts.
Responses on kahoot will lead to a class discussion.
Discussion prompts will vary depending on student responses but may include:

What is this?
What is yeast used for in a bread recipe?
How many different types of yeast are there?
What may happen If you use too little yeast in a recipe?
What will happen if you use too much yeast in a recipe?

Demo: https://sciencebob.com/blow-up-a-balloon-with-yeast/

The teacher will conduct an experiment showing how yeast works by using yeast, a small bottle, sugar, warm water, and a balloon. The yeast will react causing the balloon to fill with carbon dioxide.

Day 2:

The teacher will demo the process of making yeast dough. It will be important to show students the process and technique of kneading, proofing and shaping. Showing them the technique of rolling and shaping the dough into pretzel form will be beneficial for the students.  

 

Student Instructions

Day 1:

Students will read the prompt: “What is this and what is its purpose?” Each students will have an electronic device. Students will access the website kahoot.it and enter the pin number to take part in the classroom discussion board. Students will discuss the following questions regarding the prompt written on the board. 

What is this?
What is yeast used for in a bread recipe?
How many different types of yeast are there?
What may happen If you use too little yeast in a recipe?
What will happen if you use too much yeast in a recipe?

Students are assigned to take notes during the demonstration to help with their write up explaining the process. 

Day 2: Students will be expected to take notes throughout the demonstration. They will need to refer back on proper techniques to use when creating their dough. 

 

 

3 Wrap Up-Synthesis/Closure

Day 1:

 As students are watching the experiment have them take notes explaining the process of what is happening in their own words in approx. one paragraph. They will turn this in as they exit class.

 

Day2:

Students will be assigned a lab station. Each station will work on creating dough, using yeast. Each student will practice the techniques used to work the dough. Fermentation, kneading, proofing will be done in this step. They will leave the dough to rise overnight.

Day 3: Summative Assessment

Show a short video on  Youtube demonstrating the technique of making the pretzel shape. URL: https://www.youtube.com/watch?v=XFFTyyQwVNs (show first 3 minutes)
Students will take their rested dough (briefly re-work) and shape the dough into pretzel form. This will test their proportion skills in measuring out the dough so pretzels are similar in size.  While the pretzels are baking students will be making a side of cheese sauce to go with their pretzels.
Students will use Socrative, to create an exit ticket individually describing ONE way they could modify the recipe and why. This may include adding jalapenos in their pretzels or using a different type of flour etc.
When students have completed their lab they must complete the pretzel lab procedure evaluation, due the following day.

Student Instructions

Day 1: Take notes on the demonstration. You will write  one paragraph explaining the process of the demonstration. 

Day 2:

Students will work with their lab groups creating dough, using yeast. Practice the techniques of fermentation, kneading, and proofing. 

Day 3: Summative Assessment

Students will watch a Youtube video that demonstrates the technique used to shape dough into pretzel form.

Students will take their rested dough they have previously made and begin to roll out and shape the dough. While the pretzels are baking students will make a side of cheese sauce to go with their pretzels.

Once, the lab is complete, students will use  Socrative  to complete an exit ticket. Prompt: Describe ONE way you could modify the recipe and why." 

Students must complete their lab procedure evaluation, and is due the following day.
