  1. TEK 7.13(13) Organisms and environments. The student knows that a living organism must be able to maintain balance in stable internal conditions in response to external and internal stimuli. The student is expected to: investigate how organisms respond to external stimuli found in the environment such as phototropism and fight or flight; and describe and relate responses in organisms that may result from internal stimuli such as wilting in plants and fever or vomiting in animals that allow them to maintain balance.

  2. 4.20.11 Word Wall TEK 7.13 • We will create a word wall for homeostasis TEK 7.13 • Warm up: Name the 4 ways we know there has been a chemical change:

  3. Homeostasis: • a living organism must be able to maintain balance in stable internal conditions in response to external and internal stimuli

  4. Internal Stimuli: • when an organism responds to an unbalance inside its self. • Ex: vomiting, fever, wilting plant

  5. External stimuli when an organism responds to its surround environment EX: fight of flight or phototropism

  6. Fight of flight: • if an organism feels threatened it responds with adrenaline, which prepares the body to fight or run away.

  7. Phototropism: • when a plant grows towards the light source

  8. Recall: stimuli is something an organism reacts to • Summary: Explain what type of stimuli you are reacting to when you vomit and have a fever • Out: Explain what type of stimuli a plant is reacting to when it wilts ** use complete sentences with capital letters, periods, and NO PRONOUNS! **

  9. 4.19.11 Edusmart 7.13 • We will use edusmart to learn about stimulus and response and take a quiz • Warm up: describe the difference between stimuli and response

  10. Recall: Phototropism is when a plant responds to the stimulus of light by growing towards the light source • Summary: all organisms have to respond to stimuli in order to survive • Out: Explain a situation where you think your body would go into fight or flight response. Do you think you would fight or flight, why? ** use complete sentences with capital letters, periods, and NO PRONOUNS! **

  11. 4.25.11 Stimuli/response Lab • We will conduct and investigation to understand stimuli and response. • Warm up: This element has a high luster and is malleable… what type of element is it?

  12. With a partner sort your cards into stimulus and response.

  13. Complete each station. In your journal you need to record the following: • Lab name • The problem/purpose • Data chart and data collected • Complete sentence answers to analysis questions

  14. Recall: organisms can respond to internal or external stimuli • Summary: Reacting to an abiotic factor would be an example of what kind of stimuli? (use a complete sentence without pronouns) • Out: Complete the chart with as many examples as you can think of:
