Standard E - The Living Environment
Students
understand that cells are the basic unit of life, that all life as we know it has
evolved through genetic transfer and natural selection to create a great
diversity of organisms, and that these organisms create interdependent webs
through which matter and energy flow. Students understand similarities
and differences between humans and other organisms and the
interconnections of these interdependent webs. Students describe the cycle of birth, development, and death in different organisms and the ways in which organisms resemble their parents.
a. Give examples of how organisms are like their parents and not like them.
Group Activity: Instruct students to come to the front table choose an envelope. In each envelop will be different organisms their parents and babies. Students will match them. Each group will have an opportunity to work with each envelope. There will be an envelope for insects, mammals, reptiles, and fish. Color code the envelopes. When each group has completed the assignment they may come to the table and get the corresponding answer chart.
Classroom Demonstration: Gather the class on the rug. Explain to students that we are going to talk about how we are like our parents. Read the book Are You My Mother by P. D. Eastman. In this book baby bird goes looking for her mother, asking many different animals "Are you my mother?". Discuss with students how baby bird knew who was or was not her mother. What kind of characteristics did baby bird look for?
Effective Questions: How did you identify the babies and their parents?
What did you learn from this activity?
b. Describe the life cycle of a plant or animal (including being born, growing, reproducing, and dying)
Students will plant their own seeds. They will document this activity in their science journal. Students will water and document the life cycle of their plant each day at circle time. Eventually they will have a plant to take home.
Classroom Demonstration: Discuss with students the idea of life cycle. Each living organism has a life cycle. There are four stages, although some have only three we are going to focus on organisms that have four stages. Think about plants. Present several books on plants for children to preview while they are waiting for their turn in group activity. Read the book The Tiny Seed by Eric Carle. Discussing the life cycle of the seed.
Vocabulary: germination, pollination, annual, perennial
Effective Questions: Using your science journal what can you learn from your notes?
Is there a pattern between plants and animal life cycles? Do they have anything in common?
