10.18.10 Seedling Vocabulary OBJ: We will create a flip book in our journal to learn about plant seedling words TEK: 7.7c Warm up: Draw the pictures! What type of simple machine is this? Which machine would you need less force? WHY? 1. 2.

RECALL: Photo=light Geo= earth Hydro= water Tropo= to turn Ism = a system Thigmo = touch

Flip Vocabulary: Only cut the dotted lines! Past only the little tab labeled Tropism onto your through. Glue tab into your journal

Geotropism Define: How plants respond to the force of gravity. Draw the pictures:

Geotropism:

Phototropism Definition: How a plant grows toward the light.

Phototropism

thigmotropism Definition: Plants bending or growing because of touch

TESTS and RETAKES! The retake test will not be identical so be sure to study before you come to make it up!

Summary: Explain why all the words we learned today have tropism in them. What does this mean? OUT: Describe how the acorn has both potential and kinetic energy at the same time! 1st part of test corrections

10.19.10 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.

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).

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

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

New Plant Plants need water, warmth, nutrients from the soil, and light to continue to grow. http://www.mbgnet.net/bioplants/grow.html

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

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. 2nd part Test Corrections

10.20.10 Natural Disasters IN: OBJECTIVE: The students will describe different catastrophic events effects on ecosystems using articles TEKS: 7.8A Warm-up: Calculate the amount of work done when Bob pushes a 500N box 10 meters.

Hurricane Katrina

Gulf Oil Spill

What is an Ecosystem? A community of organisms and their abiotic environment Community – different types of organisms living together in the same place at the same time Abiotic factors – anything that was never alive and cannot be alive

How does it impact the ecosystem? Floods Hurricanes Earthquakes Tsunamis Wildfires Tornadoes Volcanoes Drought
