1. September 13, 2013Do Now: copy this chart in your notes Stimulus Response • Phone Rings • Touching a pan on a burner • You get an F in class • Answer it, ignore it, silence the phone • Pull hand away, Burn, get a mark • Punishment, go to tutoring What do all of these have in common?

2. Vocabulary Stimulus Response • A stimulus is anything that causes a reaction in a living organism. • A response is the reaction caused by the stimulus

3. Abiotic factors cause reactions in living things • REMEMBER: • Abiotic factors are non-living parts of an ecosystem • Air • Water • Climate • Soil (both abiotic and biotic) • Sunlight • Temperature • Biotic factors are the living or once living parts of an ecosystem

4. Activity 1: Responding to Balancing Challenges • Procedures: • Place a piece of tape or sticky note on the floor. • Take turns having one volunteer at a time try the following challenges while the rest of the group observes the event. • Challenges (30 seconds each) • Balance w/ one foot on the tape and both eyes open • Balance w/ one foot on the tape and both eyes shut • Balance w/ one foot on the tape, eyes open, and arms held tightly against your side • Slowly spin around 4 times, and then balance with one foot on the tape w/ eyes open • Slowly spin around 4 times, and then balance with one foot on the tape w/ eyes shut

5. Activity 1: Responding to Balancing Challenges • Record the answers to the following 3 questions. • What did you observe as the volunteer tried to maintain a balanced position? • What actions did the person take to recover his or her balance? • Which challenge was most difficult? Why?

6. Respond verbally to the following questions: • How did it feel when you stood with one foot on the sticky note w/ your eyes open? • How did it feel when you stood with one foot on the sticky note w/ your eyes closed? • How did it look when your partner was trying to balance on one foot with closed eyes? • Why was the feeling different with your eyes closed? • What happened when you spun around 4 times and then stopped?

7. Activity 2: A Delicate Balance Have you ever watched a gymnast walk on a balance beam? With each step, the gymnast must make small balancing movements similar to the ones that you made when balancing on the piece of tape. Years of training and practice help the gymnast make very small balancing movements to avoid large over corrections that might cause a loss of balance. This allows the gymnast to give a smooth, balanced performance. The semicircular canals in our inner ears contain tiny hairs that help us maintain balance or equilibrium. Gravity plays an important role in balance. The tiny hairs can be moved by fluid as it is pulled downward by the force of gravity when our head changes position quickly. Nerves carry the message from the hairs to the brain, which causes the body to react and regain balance. This might cause a dizzy or spinning sensation, especially when sight is not being used to help the body as it maintains balance.

8. Activity 2: A Delicate Balance Most living things thrive in a balanced environment, and can tolerate a very narrow range of changes in their external environment without suffering harm or death. In order to survive, living things must constantly make adjustments to keep internal conditions constant and balanced, in spite of changes that occur in the external environment. For example, when warm-blooded animals are in cold temperatures, they may respond by shivering to increase body temperature by muscle movement. They also may develop “goose bumps” by making hair stick out straight to trap a layer of air for insulation. In extremely hot temperatures, animals may respond by sweating or panting to cool off. These responses automatically occur when body temperatures rise above or fall below the animal’s most favorable temperature range.

9. Activity 2: A Delicate Balance Plants have different types of response than animals, because plants have different needs. Light is one of the most important abiotic factors in a plant’s environment because it is needed for photosynthesis. Plants have special growth chemicals that will cause a plant to grow toward light, even if it causes stems to have a sideways growth. Many animals, including humans, also respond to light.

10. Activity 2: A Delicate Balance • http://www.youtube.com/watch?v=vAgGeLJ37iU • Questions: • Describe the response of the volunteer’s eyes to the light. • What is the relationship between the amount of light and the pupil size? • Why does the eye respond to light in this way?

11. Activity 2: A Delicate Balance • Verbal Questions: • What is the relationship between the amount of light and pupil size? • Why does the eye respond to bright light by decreasing the size of the pupil? • Why does the eye respond to dim light by increasing the size of the pupil? • What is the external environmental factor that is being controlled by the response movements of the eye? • Can you think of examples of times when your eyes could not respond and balance the amount of light entering the eye?

12. Activity 3: Responses to Abiotic Factors in an Ecosystem • Place a check mark in the box that best represents the stimulus for each response listed. Be prepared to justify and share your results with the class.

13. Wrap-up • Turn in paper with these questions answered as you leave: • What are some of the ways that other living things stay in balance. • Why is it important for organisms to be able to respond to/interact with both the living and non-living parts of their environments? • What are the non-living parts of an organism’s environment called? • What are some examples of abiotic factors in an ecosystem? • What are the living parts of an organism’s environment called? • What are some examples of biotic factors in an ecosystem?
