Big Idea
Plants structures and functions evolve over time.
Essential Questions
How do seeds grow and develop into plants? Include factors that affect development.
Why are fruits and seeds important adaptations for plants?

Science & Engineering Practices
Obtaining, Evaluating, and Communicating Information
Obtaining, evaluating, and communicating information in 9–12 builds on K–8 experiences and progresses to evaluating the validity and reliability of the claims, methods, and designs.
  • Communicate scientific information (e.g., about phenomena and/or the process of development and the design and performance of a proposed process or system) in multiple formats (including orally, graphically, textually, and mathematically). (HS-LS4-1)
Content/Core Ideas
  • Seeds go through different stages
    • dispersal  (affect by animals, environment...)
    • dormancy (affected by the environment...)
    • germination (seeds need the right conditions to grow)
  • Seeds allow plants to increase diversity.
  • Seeds lay dormant until conditions are right.
  • Fruits attract animals allowing for dispersal of seeds through excretion.
Learning Practices
CCSS.ELA-Literacy.WHST.11-12.4 Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience.

Design and use graphic organizers to show relationships between and within content topics (flowcharts, venn diagrams, cladograms, mind maps...).

Active Engagement Partner work:  Students work with partner(s) to solve problems, build models, think pair share...
Academic Vocabulary
germanation
dormancy
Fruit
Plant diversity

Assessments
Here are SOME ways students can demonstrate knowledge and understanding of the essential questions.
  • Students will examine the dormancy and germination of radish seeds by observing the seeds over several days, measuring growth and graphing plant growth vs. time.
  • Students will design a lab that exams how different factors affect seed development and growth.
  • Students will create an infomercial to “sell” a fruit to a potential “buyer” - an animal that will disperse the the seeds (include how the fruit forms, why it might appeal to the animal and how it benefits the animal)
