1 Slide 1 Our Learning Garden Grade 4 Lesson 1 4 Lesson Summary Lesson 1 Begins examining the concept of heliotropism (sunflowers follow the sun) and exploring how solar panels mirror the behavior of sun flowers (sun followers) Investigate how technological developments often mirror physical adaptations. The students will engage in activities to understand the concept of heliotropism and watch a short video. Lesson 2 Students explore the food web, students learn how energy transfers in the web via photosynthesis Recognize that the food chain is a system in which some of the energy from the Sun is transferred eventually to animals. GLO: D2, D4, E2. Students role play in an interactive food chain game. We continue the sunflower theme as the sunflowers are the producers Construct food chains and food webs, and classify organisms according to their roles. Include: producer, consumer, herbivore, omnivore, carnivore, predator, prey, scavenger. Lesson 3 Explores how the food chain is affected by the activities of man. We explore the concept of biomagnification so that students can understand how they are affected Investigate natural and humancaused changes to habitats, and identify resulting effects on plant and animal populations. Include: endangerment, extinction. GLO: B1, B5, D2, E3 Lesson 4 further investigates how Investigates how technological developments often mirror physical adaptations We examine the sunflower seed and the spiral placement of seeds. The students do a simple experiment that involve packing shoes. This lesson includes a short video Nature by Numbers in which we expand the concept to math (technological developments often mirror physical adaptations) Lesson 5 Brings continuity to the subjects discussed as we explore the distribution of leaves in nature to efficiently gather energy from the sun. How math enables leaves to make maximum use of sunlight like solar panels. Lesson 6 Students grow sunflower greens to observe and record leave distribution, Our goal is to meet many curriculum outcomes as we introduce the students to eating sunflower greens that are incredibly nutritious All lesson plans and related files for download The files are open so feel to change content to class requirements. Our Slide 2 Lesson Plan 1 Lesson Summary Lesson 1 Begins examining the concept of heliotropism (sunflowers follow the sun) and exploring how solar panels mirror the behavior of sun flowers (sun followers) Investigate how technological developments often mirror physical adaptations. Students get to explore hands on the concept of heliotropism. Sunflowers follow the sun Watch the video How time flies and sunflowers catch (follow the sun) the sun 2.02 minutes Activities have the students draw pictures of the sun and sunflowers, you can then have the suns walk from to the from the East (sunrise) to West (sunset) path in the classroom. The students can pretend they are sunflowers following the sun (heliotropism). Have the students follow the sunrise and sunset (path of the sun, like sunflowers do). Sunflower follow the sun to collect energy. This energy is used for photosynthesis Solar Panels follow the sun to collect energy The energy can be used to heat water or to heat solar cells that convert the suns energy into electricity Our Slide 3 The Sunflower name also originates from the fact that growing sunflowers do something pretty amazing. They actually turn their faces toward the sun to follow it!

2 Slide 4 Sunflowers face in the morning. In the afternoon Slide 5 Turning to the the sun is called heliotropism, Helios is a Greek word that means SUN Tropism in Greek means turning HELIOTROPISM= Sun + turning Would you like to pretend you are a sunflower, turning towards the sun? Slide 6 Why would sunflowers face East in the morning? Use students as markers in the classroom to identify East, West, North, and South in the classroom. Have students draw North, South, East and West signs.

3 Slide 7 Why would sunflowers face West in the evening? In the afternoon Have some students draw the sun and enact the path of the sun, sunrise to sunset. The student can pretend they are sunflowers following the sun. Slide 8 How time flies and sunflowers catch the sun The movie is 2 minutes Download film at Link to film Slide 9 Solar Panel

GLO: D2, D4, E2. Link to Play some online food chain games Students role play in an interactive food chain game. We continue the sunflower theme as the sunflowers are the producers Construct food chains and food webs, and classify organisms according to their roles. Include: producer, consumer, herbivore, omnivore, carnivore, predator, prey, scavenger. The Food Video Web 3 minutes

5 Slide 13 Sunflower follow the sun to collect energy. This energy is used for photosynthesis Solar Panels follow the sun to collect energy The energy can be used to heat water or to heat solar cells that convert the suns energy into electricity Slide 14 Slide 15 Play some online food chain games

6 Slide 16 The Food Video Web 3 minutes Watch the video It s the food web 1 minute Link to video Download at Slide 17 PLANTS MAKE THEIR OWN FOOD They don t bake, fry or boil it They Photosynthesize it THE SUN IS THE BEGINNING OF THE FOOD CHAIN Slide 18 Plants capture the sunlight and use it as food. Sunlight is very important to plants because that is one of the ingredients for there food. SUNLIGHT The ingredients plants need to make food are AIR SUN WATER AIR SOIL WATER NUTRIENTS

7 Slide 19 SUNLIGHT AIR Plants make a green food called chlorophyll. That is why the leaves are green WATER NUTRIENTS SOIL Slide 20 Slide 21 THE SUN IS THE BEGINNING OF THE FOOD CHAIN

8 Slide 22 The Food Chain always starts with plants If the soil or water are not clean or chemicals are used to grow plants, it travels to you and me in the food chain. Slide 23 Your teacher will assign you a position in the food chain Slide 24 If you are a carnivore draw the caveperson People eat plants, such as vegetables and fruits. We also eat animals and animal products, such as meat, milk, and eggs. Consumers can be carnivores (animals that eat other animals) or omnivores (animals that eat both plants and animals).

9 Slide 25 If you are a herbivore draw a picture of a chicken Consumers The next trophic levels are made up of animals that eat producers. These organisms are called consumers. Primary consumers are herbivores. Herbivores eat plants, algae, and other producers. Slide 26 If you are an egg what are you in the food chain? You can grow into chicken if you are not consumed by a consumer. Are you an animal by product? Slide 27 If you are a producer draw a picture of a sunflower with seeds Producers Producers make up the first trophic level. Producers, also known as autotrophs, make their own food and do not depend on any other organism for nutrition. Most autotrophs use a process called photosynthesis to create food (a nutrient called glucose) from sunlight, carbon dioxide, and water.

10 Slide 28 FOOD CHAIN GAME Activity best done in smaller groups of 8 10(adjust number based on classroom size). A)Four students are sunflower plants give them each some seeds B)Two students are the chickens C) Two students can be the egg D) Two students can be the cavepersons IMPORTANT for students to learn that if one part of the food chain is disrupted the entire food chain can collapse! That is why you do not eat all the seeds, eggs or chickens! Have the chicken eat some seeds, Lay an egg, then have the caveman destroy the food chain by eating all the chickens and eggs. Do another variation where sunflowers die and there are no seeds so the chickens starve. Have the students do a food chain where the eggs do not hatch because of chemical in the food chain. Slide 29 Pollution on land and farmers fields drain into rivers and lakes Pesticides and pollution can effect the strength / thickness of the birds egg shell. Oil, lead and mercury are some of the causes. Higher you are in the food chain the higher concentrations of toxins you eat. Slide 30 Lesson 3 Lesson 3 examines the relationship between food chain and pollution Students are introduced to the concept of biomagnification Identify substances that pollute air and water, and describe ways of reducing such pollution. GLO: B3, B5, D3, D

11 Slide 31 Pollution can effect the shells of eggs Slide 32 What do you think happens when a egg shell is thin and weak? Slide 33 What do you think happens when a egg shell is thin and weak?

12 Slide 34 What do you think happens when a egg shell is thin and weak? The eggs will not hatch and you do not get any chicks. Slide 35 Eagle were nearly extinct as their egg shells are very sensitive to pollution. Slide 36 Does pollution an a food chain affect you?

13 Slide 37 Biomagnification Blue dots are pollution What is happening? Slide 38 Species on the food chain get more chemical or pollution in their body as they go up the food chain. This process is called biomagnification. It comes from the word magnify. Do you have a magnifying glass? Slide 39 Yellow circle is pollution What is happening? Is this biomagnification?

14 Slide 40 Pollution runs into our rivers, lakes and oceans Slide 41 Pollution runs into our rivers, lakes and oceans Slide 42 Some farmers aerial spray crops with chemicals to kill weeds Where do all the chemicals go?

15 Slide 43 Some farmers sprays crops with chemicals to kill weeds Where do all the chemicals go? Slide 44 Pollution runs into our rivers, lakes and oceans Slide 45 Can you draw a picture of biomagnification? Identify what the source of the pollution is glyphosate farmers use this to control weeds Draw all the species in the food chain Show the process of biomagnification glyphosate

16 Slide 46 Lesson 4 Lesson 4 further investigates how Investigates how technological developments often mirror physical adaptations We examine the sunflower seed and the spiral placement of seeds. The students do a simple experiment that involve packing shoes. This lesson includes a short video Nature by Numbers in which we expand the concept to math (technological developments often mirror physical adaptations) Slide 47 Look closely at the sunflower. Slide 48 Do you see a pattern?

17 Slide 49 Slide 50 Is it a spiral pattern Slide 51

18 Slide 52 Slide 53 Slide 54 Nature by Numbers A movie inspired on numbers, geometry and nature, by Cristóbal Vila 4 minutes running time Down load at Youtube Link to movie

19 Slide 55 Nature is great at math and uses math often. The spirals you see in the sunflower are a math formula that allows the most seeds to get placed in the head of the seed Slide 56 Sunflowers use math as well to place the most seeds in the plant. See the spiral pattern. It is a math formula Slide 57

20 Slide 58 Nature is great at math and uses math often. Can you copy nature and position the shoes differently? Slide 59 Nature is great at math and uses math often. Can you copy nature and position the shoes differently? Try it with your classes shoes. Slide 60 Try it with your classes shoes. What Happened? How many more shoes were you able to put in a box?

21 Slide 61 Plants are alive, just like people and animals. How do we know this? Living things all do certain things: They grow and die. They need energy, nutrients, air, and water. They produce young. (Example sunflower seeds) They are made up of cells. They react to what's around them (Example sunflowers follow the sun) Slide 62 Lesson 5 Lesson 5 Brings continuity to the subjects discussed as we explore the distribution of leaves in nature to efficiently gather energy from the sun. How math enables leaves to make maximum use of sunlight like solar panels. Slide 63 Technology mimics nature Solar panel and sunflower heliotropism Spiral seeds in sunflower use math formula that can be used for packing efficiently Let s study leaves as they efficiently gather energy from the sun.

22 Slide 64 Slide 65 Slide 66

23 Slide 67 Draw and label where the 4 th leaf will grow. Slide 68 Draw and label where leave 5 and 6 will grow. Slide 69 The leaves grow in a spiral pattern to receive the maximum amount of sunlight to assist in photosynthesis.

24 Slide 70 Many plants use math to position the leaves receive the maximum amount of sunlight. Follow the line from start to finish and follow the order of the 10 leaves. Can you number the leaves? Leaf 3 Leaf 1 Leaf 10 Leaf 4 Leaf 2 Slide 71 Leaves are positioned to enable them all to make maximum use of sunlight. This concept prevents leaves from shading one another so they get maximum sunlight Slide 72 Lesson 6 Lesson 6 Students grow sunflower greens to observe and record leave distribution Students learn to develop data collection and observation skills for days. Our goal is to meet many curriculum outcomes as we introduce the students to tasting and eating sunflower greens that are incredibly nutritious

27 Slide 79 Lettuce is a leaf Sunflower Greens LEAF LEAF Slide 80 Try eating some plain, in soup or on a sandwich. REMEMBER TO GET YOUR TEACHER TO RINSE THEM! Sunflower Greens taste great and are very healthy! Slide 81 Plants capture the sunlight and use it as food. Sunlight is very important to plants It is one of the ingredients for there food. The ingredients plants need to make food are SUNLIGHT AIR SOIL WATER Page 4 of the workbook Show picture pass it around the class. SUN WATER AIR SOIL

28 Slide 82 Print page 7 from the workbook, distribute to students Slide 83 We will be growing sunflowergreens from the kit and harvesting some when they are dicotyledons. Dicotyledons have two leaves. We will let some grow to record and observe the formation of leaves They are rich in chlorophyll, enzymes, vitamins, and proteins. The greens are a rich source of lecithin and Vitamin D. They are 25% percent protein by weight. TASTE GREAT AND ARE HEALTHY! Put them on sandwiches, salads or in soup. Eat them anyway you want to.. Slide 84 Instructions for Growing Sunflower Greens 1) Soak the seeds in cool water for hours.. 2) Rinse the seeds before planting Take out the sunflower grow kit. Assign the students tasks

29 Slide 85 Instructions for Growing Sunflower Greens 3) Put the soil into the tray, water with 350 ml of water (add fertilizer packet to water) 4) Remove the seeds from water, rinse / strain and spread out evenly on top of the soil. 5) Gently/lightly press the seeds into the soil. 6) Spread the soil on top of the seeds, so that the seeds are completely covered around 2cn of soil. 7) Lightly water the tray 8) Place the tray about centimeters from the fluorescent lights or grow lights. (in 3 4 days the sunflowers will start to emerge and will be ready to eat in about 7 days, they will have 2 leaves. Continue to next slide Slide 86 Instructions for Growing Sunflower Greens 9) Continue to water to keep soil moist When the sunflowers emerge about 6 (tall they will have two leaves, cut them and rinse. Eat the stems as well, great in salads or garnish on sandwiches Slide Observe record and draw the they leaves as they emerge. 2. What did you notice about the emerging leaves? 3. Do they grow in a manner that exposes the leaves to the most solar energy? Data collection and observation skills.
