Norah Burdette MATP 610 Stutzel November 9, 2015 PEPPERDINE UNIVERSITY Graduate School of Education and Psychology Second Lesson Plan Lesson Title: Photosynthesis and the Pumpkin Seed Context: 5th Grade Number of students in the class: 30 Time: 45 Minutes Materials: - 10 digital microscopes (1 per every 3 kids) - 1 digital microscope connected to the TV - 10 freshly picked basil leaves - 20 plastic cups - Soil to fill each cup halfway - 10 pumpkin seeds - 10 large Ziploc bags - 10 permanent markers Key Standards: 5-PS3-1: Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun. 5-LS1-1: Support an argument that plants get the materials they need for growth chiefly from air and water. Measurable Objectives Learning Target - By the end of today’s lesson, I will have learned enough about the structure of plants and the process of photosynthesis to make an educated hypothesis predicting the growth patterns of both a pumpkin seed I plant in soil, water and leave in open-air sunlight and a pumpkin seed that has had one ingredient, of my choosing, of the photosynthesis recipe removed. I will show that I have learned this by documenting my hypotheses for the predicted growth of each seed in my science journal and by then making verbal observations and conclusions the following week via group and class discussion. Skills or processes - Teamwork, learning to use a microscope, understanding the structure of a basil leaf, planting, designing my own experiment within my group and making predictions about the growth patterns of two planted pumpkin seeds. Academic Language: 1 Norah Burdette MATP 610 Stutzel November 9, 2015 Hypothesis, Mesophyll, Chloroplast, Photosynthesis, Phloem, Xylem, Cholrophyll Background: The students in this science lab will have already experienced two lessons related to plant structure and how their nutrients are absorbed. They will come to class knowing what phloem and xylem are and how they support life in a plant. They will also come to class with hands-on experience of the celery experiment and have an understanding of how water and nutrients are absorbed by plants. Motivation: The science lab is an environment where success is built upon collaboration, thus each student will work within a group. The motivation behind this lesson is to help visually demonstrate how the process of photosynthesis works and discuss why it is so important to our health and the health of our planet. Connections to prior knowledge/assets: Students should have prior knowledge of the structure of plants and how plants absorb nutrients and water. Lesson Sequence: Groups will consist of six students working at each lab station and two mini-groups within the larger group for microscope and planting work. The students will come in, put on their lab coats and head straight to the microscope at their table. Per the directions written on the board, they will examine a previously mounted basil leaf and then we will provide direct instruction illustrating the structure of the leaf and building upon previously acquired schema. The topic of photosynthesis will then be introduced, incorporating their understanding of nutrient and water absorption in plants. Once we have checked for understanding, we will start the hands-on activity and have them plant two pumpkin seeds per table, leaving one as the control and letting them design the experiment of the other seed by removing one of the steps in the photosynthesis process (light, water, air, or soil). Anticipatory Set: Students will enter a dark science lab and the board will read, ‘Take a look. What do you see ?’. There will be a microscope set up on each desk with a basil leaf slide and will give them time without instruction to observe and discuss what they see within their groups. Based on: Vygotsky, Theory of Play/Constructivist Theory/Unguided Inquiry/Cooperative Learning/Inductive Learning/Inquiry Training Time: What the Teacher Does: 5 mins Say: Nothing Model: Looking in the microscope What the Students Do: Put on their lab coats, take turns looking in the microscope and discussing their observations. 2 Norah Burdette MATP 610 Stutzel November 9, 2015 Introduction: We will open up the floor for predictions about what we will be learning today and then introduce the topic of photosynthesis via a digital microscope connected to the television that mirrors their own microscopes. Based on: Constructivist Theory/Instructional Scaffolding/Deductive Strategy/Cooperative Learning/Direct Instruction Time: 10 mins What the Teacher Does: Say: We wanted you to see first-hand how amazingly complex leaf structures are. We are now going to utilize what we have learned over the past two weeks about plant structure (phloem, xylem and nutrient and water absorbtion) to dive a little deeper into leaf structure. Model: Identify, via digital microscope connected to the television, the additional parts of leaf structure that are essential for photosynthesis (mesophyll and chloroplast) Check for understanding: Ask if everyone can see these structures and discuss in class how each of these structures contribute to the process of photosynthesis. What the Students Do: Look at the microscope being broadcast via TV and into their own microscopes and identify the mesophyll and chloroplasts. Ask questions, answer teacher questions and draw the leaf they see in their science journal, labeling the mesophyll and chloroplast. Body of Instruction: Next, we will dive deeper into the larger process of photosynthesis itself and show the video ‘Photosynthesis in Plants – Animation for Kids’ to provide the students with more detailed information about the process and equation used in photosynthesis. Differentiation/Scaffolding: We will create diverse groups of six students, making sure to include both genders, a variety of races and all learning levels. These students are average-learning fifth-graders who speak English as their first language, so other than the instructions in the beginning, we don’t plan on providing much scaffolding. Based on: Constructivist Theory/Instructional Scaffolding 3 Norah Burdette MATP 610 Stutzel November 9, 2015 Time What the Teacher Does: What the Students Do: 8 mins Say: Take a look at this video and pay Watch video, jot notes and ask questions special attention to the ‘ingredients’ after video ends. needed in the photosynthesis recipe. You may want to jot down some notes. Model: Watching video and taking notes. Check for understanding: Ask if there are any questions. Check for understanding: After the video ends, we will answer any questions the students may have. We will review the photosynthesis equation learned and review why photosynthesis is so important to our health. We will then begin the hands-on pumpkin seed experiment to drive home the topic of photosynthesis with active learning. Differentiation / Scaffolding: We will walk around the room while the students are planting their seeds and provide support as needed. Based on: Constructivist Theory/Instructional Scaffolding/Cooperative Learning Time 20 mins What the Teacher Does: Say: Ask the students to plant one control group (a pumpkin seed planted in soil, watered, with access to air and sunlight) and to then pick the variable (soil, water, air or light) that they would like to eliminate from the photosynthesis process. Allow them time to discuss, assign jobs and get started. Model: Planting of the pumpkin seeds in the control cup. Model one option for variable elimination by placing the planted pumpkin seed cup in a Ziploc bag and then squeezing the air out. What the Students Do: Students work together to plant one pumpkin seed control cup and then discuss as a team which photosynthesis variable to eliminate (water, soil, air or light) and how to do this. They can use the suggestions we give them of placing their variable cup in the closet, not watering it, placing it in a sealed Ziploc bag, not using soil or any other creative variable removal method they can agree upon. They will then plant both seeds, label their cups and write their hypotheses for anticipated plant growth over a one-week time span in their science journals. 4 Norah Burdette MATP 610 Stutzel November 9, 2015 Elaborate on the content : As they are working in their groups, we will walk around and answer any questions, provide support and suggestions for photosynthesis variable elimination. We will discuss possible outcomes and ask probing questions to help keep them on task. Differentiation / Scaffolding: Ask them to take a vote on which photosynthesis variable to eliminate if they are having trouble coming to a consensus or pick one for them if they seem unengaged. Based on: Vygotsky, Theory of Play/Constructivist Theory/Instructional Scaffolding/Cooperative Learning/Inquiry Training Time What the Teacher Does: During Say: Provide support, probing Activity questions and help where needed. Model: Show them possible variable elimination choices and suggestions for how they can be accomplished. What the Students Do: Plant both sets of seeds, discuss their predictions with their group and then write their hypotheses, including ‘why’ justification, in their science journals. Assessment : Assessment will be formative and will be conducted by observing how well each group interacted, what discussions were had and how close they seemed to be to understanding the process of photosynthesis. We will pay special attention to their hypotheses and what they thought would change in the plant growth process as a result of removing one of the basic elements/variables of photosynthesis. We will use this information to better understand their levels of comprehension and where we will need to provide additional instruction on an individual basis and/or how the groups should be reorganized. The next class will provide an additional opportunity for formative assessment and student selfassessment since we will see how closely the students’ hypotheses lined up with the plant growth results. These results will then provide a jumping off point for the next experiment or a possible extension of the photosynthesis experiment incorporating more variable elimination/addition experiments. Differentiation / Scaffolding: If students are struggling, we will provide them with additional scaffolding and if they are unable to cooperate in a group we may pull them to work with the teacher if necessary. Based on: Vygotsky, Theory of Play/Constructivist Theory/Instructional Scaffolding/Cooperative Learning/Inquiry Training 5 Norah Burdette MATP 610 Stutzel November 9, 2015 Time What the Teacher Does: 2 mins Say: When you come in next week, take a look at your plants and see how close you were to your hypothesis. Discuss why with your groups and ask questions! Higher-Order Thinking: What happens when trees are cut down? How does that affect us? What the Students Do: Students participate in the group activity, ask questions and form their hypotheses. They then leave with the higher-order thinking question to ponder over the course of the week. Reflection (after teaching): What worked; what could be changed to increase effectiveness of the lesson 6
