Quarter 4 (Unit 2)--PLANTS ON EARTH
Our 2nd Science unit for FOURTH QUARTER will focus on PLANTS ON EARTH
UNIT STANDARDS:
- 3.L.2 Understand how plants survive in their environments.
- 3.L.2.1 Remember the function of the following plant structures as it relates to the survival of plants in their environments:
- Roots – absorb nutrients
- Stems – provide support
- Leaves – synthesize food
- Flowers – attract pollinators and produce seeds for reproduction.
- 3.L.2.2 Explain how environmental conditions determine how well plants survive and grow.
- 3.L.2.3 Summarize the distinct stages of the life cycle of seed plants.
- 3.L.2.4 Explain how the basic properties (texture and capacity to hold water) and components (sand, clay and humus) of soil determine the ability of soil to support the growth and survival of many plants.
- 3.L.2.1 Remember the function of the following plant structures as it relates to the survival of plants in their environments:
Our Essential Questions for the unit:
- How do plants survive in their environments? (3.L.1, 3.L.2.2)
- How do the structures of plants support their functions? (3.L.2.1)
- How does soil impact the growth and development of plants?(3.L.2.4)
- How would you describe the life cycle of a seed plant? (3.L.2.3)
By the End of the Unit, the Students will Know...
- 3.L.2.1: Students know the names and functions of major plant parts (roots, leaves, stems, flowers). Students know that plants have special parts that perform special functions in order for the plant to survive.
- 3.L.2.2: Students know that how well plants grow and survive is determined by a combination of environmental conditions. For example, drought conditions will tend to diminish plant health and growth.
- 3.L.2.3: Students know the distinct stages of the life cycle of seed plants (seed, germination, seedling, adult).
- 3.L.2.4: Students know that different soils possess different textures and capacities for the retention of water and nutrients. Students know that soil consists of different components. Students know that these characteristics of soil influence the growth and survival of plants.
