SCUSD NGSS Curriculum Guide


 * 3-LS1-1: Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death. ** [Clarification Statement: Changes organisms go through during their life form a pattern.] [//Assessment Boundary: Assessment of plant life cycles is limited to those of flowering plants. Assessment does not include details of human reproduction.//]

Science Background for the Teacher:
All organisms reproduce. Reproduction is key in the life cycle of all organisms.

Key Vocabulary:

 * reproduction || birth || growth || death ||
 * diversity || life cycle || development || organism ||
 * diversity || life cycle || development || organism ||

Possible Assessments (formative and/or summative):
==== Research and create a model of a life cycle of an organism that shows the stages of birth, growth, reproduction, and death. (i.e. computer generated, drawing, 3-D, flip book) ====

* Students can not choose a mung bean for their organism for the life cycle.

Key Student Activity:
Observe and record changes in a mung bean for 5 to 10 days. Each student will have their own mung bean on their desk/table in a plastic container with a lid. Materials: mung beans, plastic container with lid, paper towels, rulers, water (keep damp at all times). Start with 10 ml of water in the container.

Common Student Misconceptions:
Beans are food for people, not a living thing. Beans are not a stage in a life cycle of a living thing.
