Stimulus Response

What do all of these have in common?

Vocabulary

A stimulus is anything that causes a reaction in a living organism.

A response is the reaction caused by the stimulus

Stimulus Response

Abiotic factors cause reactions in living things

REMEMBER: Abiotic factors are non-living parts of an

ecosystemAirWater ClimateSoil (both abiotic and biotic)SunlightTemperature

Biotic factors are the living or once living parts of an ecosystem

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

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?

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?

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.

Activity 2: A Delicate BalanceMost 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.

Activity 2: A Delicate BalancePlants 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.

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?

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?

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.  

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?

Air Water Sunlight Temperature Climate

Why are things like sand, soil, and different types of ecosystems considered to be abiotic and biotic? These things are considered to be abiotic and biotic

because they both contain living and non-living things.

The Water Cycle

1. Evaporation – liquid changes to gas

2. Transpiration 3. Condensation – gas

changes to liquid 4. Interception 5. Precipitation – liquid

water returns to the earth

6. Infiltration 7. Groundwater 8. Runoff

Why is the water cycle important?The water cycle is important because water is essential to life on earth! Most organisms are 50-90% water

Most life processes can only happen in water

Do Now: Read and answer the following question in your science notebook. Imagine an aquarium that is completely

sealed so that only light can get in. Food, water, and air cannot be added. Will the organisms in this environment survive? Explain. Through photosynthesis, plants and algae

create their own food and supply oxygen to the tank

Animals eat plants and use oxygen Animal waste fertilize plants and algae Organisms die and are decomposed by

bacteria All materials are recycled!!!

Draw the Nitrogen Cycle

Nitrogen Cycle

1. Lightning and bacteria make nitrogen into something usable for organisms 2. Animals eat plants with nitrogen and their waste puts nitrogen back into the ground3. Animals die and nitrogen goes back into the earth 4. Plants use nitrogen to make cells

Why is the nitrogen cycle important?

Nitrogen creates proteins Nitrogen is part of DNA

Both proteins and DNA are essential to all life

Animals and plants cannot use nitrogen out of the air they need to get it though the nitrogen cycle

Draw the Carbon Cycle

Carbon Cycle

1. Plants use Carbon Dioxide2. Animals release Carbon Dioxide3. Burning creates Carbon Dioxide4.Factories create Carbon Dioxide5.Waste and dead organisms release

Carbon Dioxide into the ground6.Eventually dead organisms and

waste turn into fossil fuels that produce Carbon Dioxide

Why is the carbon cycle important?

Carbon makes up all living things

The carbon cycle shows how carbon moves between living and non-living things
