__**Lesson Plan #1:**__ Topic(s) -Biology Grade Level -10


 * 5Es || Link || Description ||
 * Engage || Cucumbers to Pickles || Teacher notes &The video introduces students to the bio-engineering process of fermentation ||
 * Explore || Lab Activity || Students will ferment cucumbers -step by step- ||
 * Explain || Microbes (video)

|| PowerPoints and videos show the bio-engineering application of microorganism in agriculture. || ENGAGE The video introduces students to the bio engineering process of fermentation. I would begin this lesson by bringing cucumbers to class with me. Then I would begin a class discussion about how people have been preserving food for many years, and how the process of fermentation is one of the most important chemical methods of preserving food worldwide. We would discuss how people have been preserving food by canning and fermenting. Fermentation is the process of cultivating an environment in which “good microorganisms” like some type of bacteria can survive and flourish.Canning on the other hand is the process of thoroughly sterilizing food so that no microorganism will survive.Then I would ask them if anyone has made pickles at home, or helped to make them. Then I would ask them to name some of the ingredients that they put into the cucumbers. I hope that they would know that microorganisms are the main factors in the production of fermentation of cucumber or pickles. If none of the students mention that, I would bring that up myself. After we discuss that for a few minutes, I would show them the short video at the link below of ([|//Alton Brown shows how to make refrigerator pickles//- In a pickle-)] then I will tell them that next we are going to do a fermentation activity where using cucumbers Fermentation activity is in the Explore part of the lesson plan
 * Elaborate || Real life experiences || Field trip ||
 * Evaluate || Stud. Presentations || Students will make presentations ||

EXPLORE: Fermentation of Cucumbers, an activity for students Then the students will do lab activity “fermentation of cucumbers”.

Questions to discuss about the cucumbers: 1. What is the color of the cucumbers during the first day? 2. Are you observing fermentation? How do you know? 3. Where the microorganism come from? 4. Why do you think there is a difference between cucumbers and pickles? why?

EXPLAIN. This videos show the engineering application of microorganism in agriculture. Development in Bio-engineering and the study of microorganisms has shown that many microbes are responsible for numerous beneficial processes in the field of medical technology, food safety and quality, genetic engineering, environmental protection and agricultural biotechnology. After the video, we would spend the next few minutes discussing the different purposes of fermentation. Students will learn that Fermentation is an energy-yielding process in the absence of oxygen. Although fermentation does not provide much usable energy for the cell, it is sufficient for yeast cells. Yeast cells produce ethanol and CO2 as byproducts

ELABORATE – Students will be expose to real life applications of biotechnology in agriculture. The elaboration activity will be a continuation of the exploration lab completed earlier on the lesson. I will take students on a field trip to a local plant like the ethanol plant and to a university research laboratory. Then, I will invite a representative of Biotechnology Company, university, research laboratory to talk to the class about agricultural engineering and biotechnology in the US.

<span style="font-family: Arial,Helvetica,sans-serif;">EVALUATE: For the evaluation phase of the lesson plan students will make a presentation and I will use a rubric for evaluation. Students will collect articles from magazines and newspapers, journals dealing with biotechnology, agricultural engineering applications. Display articles in a bulletin board and talk about how they are related to the objectives of this lesson.

__**Lesson Plan #2:**__ Topic(s) -Simple Machines Grade Level - Physical Science and Physics

Bill Nye Simple Machines || <span style="font-family: Arial,Helvetica,sans-serif;">Ideas for simple machines. <span style="font-family: Arial,Helvetica,sans-serif;">Bill Nye introduces students to the engineering basics of simple machines. || <span style="font-family: Arial,Helvetica,sans-serif;"> || <span style="font-family: Arial,Helvetica,sans-serif;">Computer students' design of simple machines and presentations & a rubric. Students will use computers and find engineering applications of simple machines.Then, students will do a presentation of their work. ||
 * 5Es || Link || Description ||
 * Engage || Samsung travel video
 * <span style="font-family: Arial,Helvetica,sans-serif;">Explore || <span style="font-family: Arial,Helvetica,sans-serif;">Bike Lab Activity || <span style="font-family: Arial,Helvetica,sans-serif;">Students do activities with bikes and know that work is performed by applying force over distance. ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Explain || <span style="font-family: Arial,Helvetica,sans-serif;">Simple Machines || <span style="font-family: Arial,Helvetica,sans-serif;">PowerPoint of Simple machines. Simple machines have been used for thousands of year by humans. Students will learn to use these simple machines and be able to create a greater output force than the input force. The ratio of these forces is the mechanical advantage of the machine. ||
 * <span style="font-family: Arial,Helvetica,sans-serif;">Elaborate || <span style="font-family: Arial,Helvetica,sans-serif;">Building Stonehenge video || <span style="font-family: Arial,Helvetica,sans-serif;">Real life applications of simple machines. For compound machines, students should be able to list the simple machines that have been combined and where they are located,details ||
