## Curriculum Standards

• CCSS.ELA-Literacy.SL.7.1

• CCSS.ELA-Literacy.RST.6-8.4

Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6-8 texts and topics.

## Warm Up and Preparation

• Connect students to the topic by asking them to make a quick sketch of their family tree, including grandparents, aunts, etc.
• Now have students look at their family tree and have them determine which life cycle stage their family members are in: fertilized egg, infancy, childhood, adolescence and adulthood.
• Share answers and discuss what criteria they used to determine stages, such as age or maturity. How did they decide one was in childhood instead of adolescence, for example?
• Start the video lesson What is a Life Cycle? - Definition, Stages & Examples and pause at 1:55.
• Define 'life cycle' and make a chart on the board that contains columns titled: 'Number of Stages,' 'Length of Stages' and 'Notes.' Make several rows without labels.
