Grade 2 Unit 1-Lesson Plan 1 -7

1. Grade 2 Unit 1-Lesson Plan 1 -7 • The lesson plans for Grade 2 meet many of the learning outcomes for Grade 2. Students will explore and develop critical thinking skills as they engage in the multidisciplinary lesson plans. • The unit introduces the concept of energy with activities that reinforce food is a form of energy that is healthy eating is essential for growth and development.-GLO: B3, D1, D4, E4 • Student actvities of growing and eating corn shoots enables them to observe and record the process of aplant growing • 2-1-07 Students will understand the food that humans eat come from plants and animals, and understand the complexity of supply chains involved. GLO: B1, B3 • Students will also learn about the energy inputs required for different types of food. • We conclude with Lesson 7 introducing the concept of sustainability and food security Ourourlearninggarden.ca

2. Teacher Notes • Please allow 2-3 days for seeds to sprout • Please allow 10-16 days when sprouted seeds are planted for the shoots to be harvested Ourourlearninggarden.ca

3. Grade 2 Kit Contents • Lesson Plan 1- One ear of corn • Lesson Plan 2 –Corn seeds (pop corn seeds work), paper or Styrofoam cups and water • Lesson Plan 3 – Soil and water, Light source to put planted seeds under.

4. Lesson Plan 1 • Energy • Illustrates concept of corn seed as an incredibly versatile energy seed Ourourlearninggarden.ca

5. Energy Is the Ability To Do WorkEnergy comes in different forms: Ourourlearninggarden.ca

6. Ourourlearninggarden.ca

7. The Sun is a form of energy that plants use Ourourlearninggarden.ca

8. The Corn Seed • Corn seeds have large amounts of energy stored in them. • When a farmer plants corn seeds they can harvest the seed for many uses. Ourourlearninggarden.ca

9. The Corn Seed • Corn seeds contain energy. • A corn seed is an energy seed with many uses. • When the sun shines there is energy in the sun’s rays. • The plants (corn seed) uses the suns energy to grow. Ourourlearninggarden.ca

10. Corn The Energy Seed • Corn plants store the sun’s energy in their roots, stalks, leaves and ears. • From a seed a corn plant may grow 3 meters high. Ourourlearninggarden.ca

11. Corn The Energy Seed • The corn seeds have many uses. • Eating corn and popcorn provides energy for your body. • This energy will help yougrow and move and think. Ourourlearninggarden.ca

12. Corn The Energy Seed • Corn can be ground and fed to livestock.It is used as feed for cows, pigs and chickens. • This energy will make the animals grow fast and large. Ourourlearninggarden.ca

13. Corn The Energy Seed • You can dry the corn stalks by hanging them. • The dried corn can be burned in your woodstove • The energy in the corn seeds release heat to keep you warm on winter nights. Ourourlearninggarden.ca

14. Corn The Energy Seed • You can put the corn seeds into a large container. • The seeds will change from a solids into gas that you can burn for cooking or heat. • Some farmers heat their barns with this gas called methane. Ourourlearninggarden.ca

15. Corn The Energy Seed Corn seeds can be changed into a liquid that can provide energy to drive cars It is the same process that can change grapes into wine. This fuel iscalled ethanoland is sometimes added to gasoline. Ourourlearninggarden.ca

16. Corn is seed that has many uses. The energy in the seed can be used for many things Why don’t you plant some corn seeds and explore the ways you can use the energy in the plants you grow. Ourourlearninggarden.ca

17. Can you draw a picture showing the many uses for corn seeds? Ourourlearninggarden.ca

18. Let’s dry seeds on a husk of corn. After the seed are dry We can plant the seeds in our garden. We can also plant them indoors for corn shoots Pull back husks and complete drying in cool, dry location String the corn up by the pulled-back husks. You can do this by braiding the ears together, or simply by tying the husks to a string. Wait 60 to 90 days, and take down the string of corn. To see if the corn is dry enough to be stored as seed, gently pluck at a few kernels with your finger. If the corn breaks free from the cob, you can now store it as seed Take each ear of corn and twist it over a paper bag. Grabbing hold of your corn cob, turn one wrist one direction, and one the other direction. The corn seed kernels should fall off into the paper bag Ourourlearninggarden.ca

19. Can you write the down some of the uses of corn? Ourourlearninggarden.ca

20. Lesson Plan 2 • Lets plant some corn seeds. • But first we need to soak them in water. • The seeds will get bigger in the water and start growing. • Students get to make Styrofoam Cup Strainers Ourourlearninggarden.ca

21. As you can see, a seed of corn really is an energy seed. Why don’t you plant some corn seeds and explore the ways you can use the energy in the plants you grow. Ourourlearninggarden.ca

22. Let’s plant some corn seeds and grow some popcorn shoots Ourourlearninggarden.ca

23. Put some corn seeds in a cup add water and soak them overnight Ourourlearninggarden.ca

24. Let’s put the seeds that have been in water overnight in a cup. Make holes in the bottom of the cup with your pencil. Make a lid for the cup with paper or cardboard. Ourourlearninggarden.ca

25. Rinse and strain the seeds 2 or 3 times a day Ourourlearninggarden.ca

26. Now you can rinse the seed easily in your strainer Ourourlearninggarden.ca

27. Lesson Plan 3 • Students germinate the corn seeds • Plant the sprouted seeds in soil. • Students can print name on the pots Ourourlearninggarden.ca

28. Rinse and strain the seeds 2 or 3 times a day until the corn seeds sprout Ourourlearninggarden.ca

29. Rinse and strain the seeds 2 or 3 times a day until the corn seeds sprout.When the seed sprout, they will look like this and are ready to plant Ourourlearninggarden.ca
