Lesson Plan of Continuity of Life
General Science Grade IV
Students’ Learning Outcomes
· Explain that many characteristics in living organisms are inherited from parents.
· Explain the similarities and differences within single species by giving examples.
Information for Teachers
· When organisms reproduce they pass their characters (skin, colour, hair shape etc.) to their young ones.
· It is not necessary that all the characters of the parents pass to young ones. Some characters are changed in young ones.
Material / Resources
Pictures of some animals (cats), pictures of animals with different characters (cats of different colors), flowers (roses) of different colors, textbook
Worm up Activity
· Ask the students:
1. Are you like your parents? If yes, how?
2. Do you find any difference from your parents?
· Ask the students about their brothers and sisters that how they are similar to them and to their parents and how they are different.
· Write students’ responses on the board.
Development
Activity 1
· Discuss that when living things reproduce, they pass on their characters to offspring. Many characters are passed on to offspring as such e.g. eyes, ears and numbers of fingers etc. many other characters may change, when these pass on to offspring e.g. eyes color, hair color, height etc.
· Ask them a day before to bring the photograph of their father, mother and a separate photograph of their own.
· Write roll number or students’ name at the back of each photograph.
· Instruct them not to look at the back of photograph.
· Forms groups and give all photographs of one group to other group.
· Ask them to match each student with his/her parents on the basis of similarities.
· Ask the students why they have linked a picture to the respective parents.
· Conclude this activity by telling that the facial features of children are similar to that of parents.
· Do the same activity using other photographs of parents and children.
Activity 2
· Make different groups of students having different eye color, hair color and height.
· Ask them to collect the data of their own group and record it in their copies.
· Make a table on the board and instruct the students to copy it. Ask them to complete the table.
· After discussion among students, write the following questions on board and get answers from each group.
1. How many students have same eye color?
2. How many students have same hair color?
· Conclude the activity as: The members of the same type (species) of living things may be different with respect to many characters like hair color, eye color, height etc.

Sum up / conclusion
· When organisms reproduce they pass their characters (skin color, hair shape, eyes color etc.) to their young ones.
· It is not necessary that all the characters of parents pass to young ones as they were in parents. Some characters are changed in young
Assessment

|
· Show some pictures of flowers to the students or bring different roses in class and ask them to write how these flowers are similar and different.
|
 |
|
· Show some pictures of cats of different colors and ask them to write how these cats are similar and different.

students to copy it on their notebooks.
How we are similar?
How we are different?
