15. Seedling
IN:
OBJECTIVE: The students will illustrate seedlings using their journal and flip book.
TEKS: 7.7C
Warm-up: Name at least 3 unbalanced forces that act upon us in our everyday life.

16. Seedling Science
Plants come from seeds. Each seed contains a tiny plant waiting for the right conditions to germinate, or start to grow.
Seeds wait to germinate until three needs are met: water, correct temperature (warmth), and a good location (such as in soil).

17. Roots Anchor
The seedling's roots push down into the soil to anchor the new plant and to absorb water and minerals from the soil. And its stem with new leaves pushes up toward the light

18. Germination Process
The germination stage ends when a shoot emerges from the soil. But the plant is not done growing. It's just started.

19. New Plant
Plants need water, warmth, nutrients from the soil, and light to continue to grow.

20. Seedling

21. Poster Rubric
Title
3 requirements for growth – soil, water, temperature
Draw and Label the stages of seedlings – Root anchors plants, germination occurs, New plant
On back – Name, Date, Period

22. Recall: Turgor pressure inside the cell allows the root to break free and start to grow.
Summary: Explain how forces inside a seed begin the process for plant growth.
Out: Explain how chemical energy is transformed into thermal energy through digestion when the squirrel eats the acorn.
