Lesson Lesson Invention Of Edible Bean & Maize Seeds Full General Scientific Discipline Form V

                                                Lesson Plan of Bean & Maize Seeds

                                                    General Science Grade V

                                                      Students’ Learning Outcomes  

                                                              

·     

 

   Compare the construction & business office of edible bean & maize seeds.

·         List the functions of cotyledons.

                                  Information for teachers

·         A seed is a modest embryonic plant.

·         The outer roofing of a seed is called seed coat (Testa) which protects the tiny found within it.

·         The indicate where seed is attached to its stem is called Hilum.

·         The modest pore exterior the seed, from where air together with lite move inward is called Micropyle.

·         The part of seed which nosotros tin encounter afterwards removing the seed coat is called an embryo.

·         The embryo is a modest plant, having i or ii cotyledons, which shop nutrient material.

·         The part of axis lying towards the pointed terminate of the seed through which offset rootage arise is called radicle.

·         The part of axis lying toward the other terminate (opposite to pointed end) of the seed through which offset shoot arise is called Plume.

·         A maize seed is an oval shaped together with has i Cotyledon.

·         The edible bean seed is kidney-shaped together with has ii Cotyledons.

                                       Material / Resources

                 Flash cards / labeled pictures of edible bean together with maize seed, textbook.

                                          Worm upwards Activity

Conduct a brainstorming session (based on Grade 1V learning) amongst questions like:

·         How does a found start out its life? (Expected response: “plants grow from seeds”)

·         What is introduce within a seed that it makes a consummate plant?

Recall the students’ previous learning (unit 1; Grade V) together with inquire them.

·         How practise the monocot together with dicot seeds differ?

·         Draw diagrams of edible bean together with maize seed on board together with explicate its dissimilar parts.

                                                          Development

     Activity 1

·         Divide the students into 2 groups.

·         Give soaked edible bean seeds to i grouping together with inquire them to banker's complaint their observations inward this table.

·         Give soaked maize seeds to other grouping together with inquire them to tape their observations inward this table.

  Activity 2

• Give soaked maize together with edible bean seeds to each student.
• Ask students carefully take the seed coat from the seeds.
• Ask; why a seed needs a ‘coat’
• Demonstrate the students how to await within the seeds.
• Observe within the seeds. Point out the radicle, plumule together with cotyledons inward seeds.
• Ask students to tape their observations inward the shape of a table.
• Explain the functions of radicle, plumule, cotyledons together with seed coat.

                                           Sum upwards / Conclusion

• A seed is a modest embryonic plant.
• Its outer roofing is called seed coat (Testa).
• The embryo consists of a radicle, a plumule together with i or ii cotyledons.
• The maize seed has i cotyledon spell the edible bean seed has ii cotyledons.
• Plant rootage arises from radicle. Plant shoot arises from plumule.
• The cotyledons shop nutrient textile for the growing embryo.

                                                 Assessment

Ask next questions to the students:

    ----how many cotyledons are in that place inward a edible bean seed?

   ----What is the business office of micropyle?

  ----What practise you lot break on the external surface of the seed?

  ----Which part of seed gives ascent to stem?

• Ask students to label the parts of the edible bean together with maize seeds inward the next diagrams.
• Involve the students inward solving the questions given at the terminate of chapter / unit of measurement inward textbook.

                                                       Follow up

• Ask the students to enlist mention of seeds whose cotyledons are used every bit food?
• Collect dissimilar monocot together with dicot seeds, save them inward seed box or polythene bags together with introduce them inward forepart of the class.
