Lesson Plan Overview / Details
This lesson provides an overview of the definition of photosynthesis as well as its equation. The photosynthesis process is broken down into 3 main stages for ease of student comprehension. Students have to synthesize the information and use their knowledge and creativity to create a graphic organizer of the photosynthesis process.

Activities in this Lesson
- I Love Brownies!! - Hooks / Set
Yesterday, we began exploring the wonderful world of photosynthesis. Today, we are going to continue on our journey by expanding our knowledge. You will want to focus on these concepts because you will be using that knowledge for an activity later in the period. I LOVE brownies!! They are my favorite treat. There is simply nothing like a warm, gooey brownie to brighten my day! Does anyone else enjoy brownies? Oh. Yeah. One thing you probably don't know about me is that I don't cook. I am what you may call "Culinarily Challenged". But, one thing that I CAN do is bake. I mean, who can't rip open a Betty Crocker box and create a masterpiece of epic proportions? Are there any other Betty Crocker bakers out there? Raise your hand, be proud!!
- Ingredients vs. Products - Group Work
Who will be my volunteer? Thanks __________! On the board, draw the shape of a brownie box for us. Now, (ask class) what items make up the recipe shown on the back of the box? (Elicit response eggs, oil, water, brownie mix) Awesome! Let's give snaps to ________ for being our artist. As we look at our brownie box, how can we categorize those items? Right, they are called INGREDIENTS. Once we mix the ingredients together, we put them in the oven. 40 minutes later, the timer beeps, we open the oven door, and what do we remove? Oh yeah . . . warm gooey brownies -- the PRODUCT. Now, let's transfer what we know about making brownies to the process of photosynthesis. When I say "go", turn to face the person sitting next to you. Determine who will assume the role of "Baker" and who will be the "Taste Tester". Once you have made that distinction, return your attention to me. You have 3 seconds. "GO!" Bakers, say "Get out of my kitchen!" Taste Testers say "Yum, Yum!" Awesome! Ok, so now the fun part! When you hear "Let's Bake", the baker will list the 3 ingredients of photosynthesis and then the taste tester will list the 2 products. You will have 7 seconds. "Let's Bake" (count down last 5 seconds -- and 5, 4, 3, 2, 1) Who will be the first to share? (sharing occurs) Awesome job!! We now have the ingredients and products of photosynthesis fresh in our minds. The question is . . . what happens in the oven from the time the ingredients go in and the product comes out? Hum. . . interesting. When I say "GO", you will have 5 seconds to get two things on your desk -- your notes worksheet and a writing tool. "GO!"
- Photosynthesis PowerPoint Presentation - Lecture
- Photosynthesis Hieroglyphics - Assessment
Students are asked to take out a sheet of paper and create a hieroglyphics-type representation of the photosynthesis equation. (Refer to attached sheet with detailed information on the "Hieroglyphics Moment".) Basically, students have to re-create the equation using pictures instead of words and/or chemical symbols (i.e. students will often show a water drop, water bottle or faucet to represent water). Students are only given 5 minutes to create their hieroglyphics representation. Then, they share their creation with a partner. Afterwards, I ask for a few volunteers to share with the entire class. This activity is quick, fun for the kids and helps motivates those students who like to think in graphics and use their creativity.

- Transition to the Assessment - Other
You have been awesome learners today!! We made the journey through the stages of the photosynthesis process and now you are ready to showcase what you know. Turn your attention to the screen while we review today's challenge.
- Graphic Organizer - Assessment
Teacher Notes: Go through Photosynthesis Graphic Organizer explanation and guidelines. As you show examples of previous work, make sure to ask students to identify differences between them. Make sure to stress that there is no one correct version and encourage all students to use their creativity to showcase their knowledge of photosynthesis. (Also, make sure NOT to leave one of the examples up for students to refer to. Doing this will result in many students copying instead of processing the info and creating their own pictures in their memory.) Instructions for Students: When the music begins, move to the front lab tables, gather a piece of paper and an assortment of markers/colored pencils, return to your desk and begin working. You will have 20 minutes to complete this activity. (play upbeat music)

- Creativity Showcase - Closure
Great job! As I walked around the classroom, I saw many detailed drawings showing the photosynthesis process. Empty your hands and focus your attention on me. It has been said that all great accomplishments had once been considered impossible. Someone had to think of those ideas for them to become reality. (Have students think of great accomplishments that were once considered absurd or impossible. Capture student ideas on the writing surface. Possible answers include the airplane, the telephone, electric light, laptop computers, plastic made from corn, or genetically modified organisms.) None of these things would be possible, if it wasn't for creative people. Creative thinking is essential for leadership. So, the question remains. . . were you creative today? We shall see. . . When you hear the word "SHARE" (make talking movement with your hand), turn to the person sitting next to you and spend 20 seconds showcasing your artwork. After 20 seconds, you will hear the word, "SWITCH" (make twisting motion with your hand) At that time, switch roles. Let's review: When you hear the word (make talking movement with your hand) "SHARE", partner, 20 seconds, sharing. When you hear the word (make twisting motion with your hand) "SWITCH", switch roles. What questions do you have? (answer any questions posed) "SHARE!" (wait 20 seconds) "SWITCH!" (wait 20 seconds) And, 5, 4, 3, 2, 1. Thank you. Today, you were able to showcase your creativity!. You used your creativity to show what you know about the photosynthesis process. Excellent! Without photosynthesis, plants can't produce energy and, without energy, plants can't grow. As you leave class today, imagine what our world would be like if the world were devoid of plants. How would that impact the agriculture industry and our global population? (food for thought)
