10.18.10 Seedling VocabularyOBJ: We will create a flip book in our journal to

learn about plant seedling wordsTEK: 7.7cWarm up: Draw the pictures! 1. What type of simple machine is this? 2. 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 SciencePlants 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.

Seedling

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.

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

Natural Disaster Article

• In groups of 3 (I choose) Read natural disaster article.

• Answer questions• Talk within your group how this disaster could

impact the environment and the ecosystem.• Write a group paper on the summary and your

conversation. (3-4 SENTENCES to each question)
