1. 3 rd Grade Revisiting Plants

2. The student will: Build an understanding of plant growth and adaptations Observe and measure how the quantities and qualities of nutrients, light and water in the environment affect plant growth. Observe and describe how environmental conditions determine how well plants grow and survive in a particular environment. Investigate and describe how plants pass through distinct stages in their life cycle including: –Growth –Survival –Reproduction Explain why the number of seeds a plant produces depend on variable such as light, water, nutrients, and pollination Observe and discuss how bees pollinate flowers Observe, describe and record properties of germinating seeds

3. Desired Results Students will understand that: Organisms have basic needs. Plants can survive only in environments in which their needs can be met. Plants are part of an organized system that regulates their life cycles and their interactions with the environment. Many plants follow a life cycle with distinct stages that begins with growth from a seed and proceeds through the production of seeds.

4. Students will know: Plants require air, water, nutrients and light to survive. Environmental conditions will determine how well plants grow. Plants have distinct stages in their life cycle that begins with a seed and proceeds through the production of new seeds.

5. Wisconsin Fast Plant- Brassica Review –24 hours embryonic root appears –28 hours seedling emerges –Day 3 root system and cotyledons (seed leaves) continue to grow –Day 5 true leaves appear –Day 4-7 growth spurt –Day 9 flower buds appear

6. Essential Questions: Will the absence of basic needs affect the life cycle of plants? (How? Use scenarios such as the absence of light.) How do plants interact with their environment?(Plants can require “help” with seed production.) How do environmental factors affect plants in a habitat?(Reflect on where certain plants grow. What conditions are different from one area to another?) What are the similarities and differences between the growth of Wisconsin fast plants and other plants grown in the classroom? (Compare to lima bean plants.)
