Human Homeostasis Gizmos Answers Key

Human Homeostasis Prior Knowledge Questions & Answers 

Q.1. What does a thermostat do if it gets too cool?
Ans: When a thermostat gets cool, the red line goes down.

Q.2. What does a thermostat do if it gets too hot?
Ans: When a thermostat gets hot, the red line travels up.

Q.3. How do our bodies sometimes act like a thermostat?
Ans: How body sometimes acts like a thermostat because our temperature goes up when we are sick, and our temperature goes down when we are really cold. Another example, our bodies create heat when exercising and remove heat when we sweat.


Human Homeostasis Gizmo Warm-Up Questions & Answers

Ans: The initial air temperature is 0 degrees Celsius or 32 degrees Fahrenheit.

Q.2. What is the initial body temperature?
Ans: The initial body temperature is 37 degrees Celsius or 99 degrees Fahrenheit.

Q.3. Next to each factor listed below, write “increase,” “decrease,” or “same” based on how you expect that factor to affect body temperature
Ans: Find the answers below
-Raising air temperature: increase
-Lowering air temperature: decrease
-Adding clothing: increase
-Sweating: decrease
-Shivering: increase
-Exercising: increase


Human Homeostasis Gizmo Answer Key – Activity A

Q.1. Observe: With the Air temp. at 0 °C (32 °F) and Body temp. at 37 °C (99 °F), click Play ( ). After one simulated hour (does not have to be exact), click Pause (“). What is the body temperature after one hour?
Ans: After one hour, the temperature decreased to 36 degrees Celsius or 97 degrees Fahrenheit.

Q.2. Gather data: Fill in the first line of the data table below. Then, use the same procedure to test the effect of each of the following factors. Click Reset between each trial. Record the initial and final body temperatures in the table below. (Leave the last column blank.)
-Set the Exercise level to 70%. (All other settings in default position.)
-Set the Sweat level to 70%.
-Under Body position, select Shivering.
-Next to Clothing, click Add four times to add a sweatshirt, hat, pants, and parka.
Ans: Find the answers from the below table

FactorInitial body temp.Body temp.
after one hour

Standing still37 Degrees C36 Degrees CThe body temperature
Exercising37 Degrees C39 Degrees CThe body temperature
Sweating37 Degrees C35 Degrees CThe body temperature
Shivering37 Degrees C37 Degrees CNo Effect
Adding clothing37 Degrees C37 Degrees CNo Effect

Q.3. Analyze: To determine the effect of a factor on body temperature, compare the final body temperature with that factor to the final body temperature while standing still. Based on this comparison, fill in the last column of the data table.
Ans: Find answers to every question asked
A. Which factor raised body temperature the most?… Exercising increased body temperature the most.
B. Why do you think this process raises body temperature?… Because when you exercise, your body begins to burn fat. Your body needs energy to burn fat, so when your energy increases, it will increase your temperature.
C. Which factor lowered body temperature the most?… Sweating lowers body temperature the most
D. Why do you think this process lowers body temperature?… Sweating lowers the body temperature because exercising will increase the body temperature, and when you sweat, the water on your skin will cool the body and lower the temperature and it will help your temperature stay balanced.


Human Homeostasis Gizmo Answer Key – Activity B

Q.1. Play the Gizmo: Click Play. After one hour, the air temperature will start to fluctuate. Using what you have learned, try to maintain a steady body temperature by manipulating the Exercise level, Sweat level, Body position, and Clothing. (You may wish to click Pause occasionally to give yourself time to think.) Click Pause after at least 10 hours have passed, if you can survive that long! Select the GRAPH tab. Sketch the resulting graph into the space at right. What does this graph show?
Ans: The graph shows the comparison of the temperature outside and the temperature of my body when I exercise. At 10 hours. The air temperature was 70 degrees F, and the body temperature was 102 degrees F.

Q.2. Investigate: Click Reset. Click Play, and deliberately create a situation in which the body temperature gets so low that the simulation stops.
Ans: Find answers to every question asked
A. How did you do this?… Increased the sweat to 75%
B. What is the name for this condition?… This condition was called hypothermia. The person’s body temperature is too low.
C. At what body temperature is immediate medical treatment required?… 85 degrees

Q.3. Investigate: Click Reset. Click Play, and create a situation in which the body temperature gets so high that the simulation stops.
Ans: Find answers to every question asked
A. How did you do this?… The simulation stopped when I placed the body position on shivering and the sweat level at 75%
B. What is the name for this condition?… This condition is called hyperthermia or heat stroke.
C. At what body temperature is immediate medical treatment required?… 106 degrees

Q.4. Challenge yourself: Click Reset. Click Play, and see if you can maintain a constant body temperature of 37°C (99 °F) for 24 simulated hours or more. You will have to click Drink water or Eat food to avoid dehydration (lack of water) and low blood sugar. If the Fatigue level gets too high, you will have to rest. If you succeed, click Pause. Select the GRAPH tab and click the camera ( ) icon to take a snapshot of the graph. Right-click the image, and click Copy Image. Open a blank document and paste the snapshot into the document. You can print out the document and hand it in with this worksheet.
Ans: **Please do this task on your own. It’s Doable**

Q.5. Analyze: Select the TABLE tab. The air temperature and body temperature are recorded every hour. Scroll through the table to find the highest and lowest air temperatures.
Ans: Find answers to every question asked
A. What was the highest air temperature you had to deal with?… The highest temperature I had to deal with was 32 degrees C.
B. How did you respond to this temperature?… When the temperature started to get too high, I increased the sweating so that my body could cool down.
C. What was the lowest air temperature in the simulation?… The lowest temperature I had to deal with was -4 degrees C.
D. How did you maintain a constant body temperature at this time?… I maintained a constant body temperature by adding on clothes to keep warm.

Q.6. Think and discuss: Other than the options available in the Human Homeostasis Gizmo, what other methods are used to maintain body temperature? Try to think of both voluntary and involuntary responses
Ans: Other ways you can maintain body temperature while exercising is proper breathing which is involuntary and proper footwear which is voluntary. Footwork is important because the wrong shoes will not give you good support and you won’t be able to last long when exercising. This is also for breathing. Also, staying in shady areas would also be useful to maintain body pressure.

Q.7. Critique: On a separate page, describe the advantages and disadvantages of the model of human homeostasis used in the Gizmo. In what ways is the model realistic? What factors are not included in the model?
Ans: The model is realistic by showing us what body temperature will cause you to have a heat stroke or hypothermia. It also shows how you can prevent it by adding clothes, removing clothes, drinking water, eating, and sweating. The model is unrealistic because, in real life, everyone is not physically fit. The video shows the person jogging for 5 hours without getting tired. Me, I can’t even jog for 5 mins. So the video should have what is your physical level.

Basic Definitions – Miscellaneous

Above are the correct answers for the Gizmos (student exploration) topic “Human Homeostasis“. Now let us bring you few definitions related to this topic below:

#Q. Define Homeostasis in Humans
Ans: Homeostasis in humans refers to the ability of the body to maintain a stable internal environment despite changes in external conditions.

#Q. What are the factors affecting Homeostasis in humans?
Ans: Many factors can affect homeostasis, including genetics, physical condition, diet and nutrition, and exposure to venoms and toxins.

#Q. Define Thermoregulation
Ans: Thermoregulation in humans is the process by which the body maintains its core internal temperature (around 37°C or 98.6°F) within a narrow range. This is crucial for the body’s optimal functioning as most biochemical reactions are temperature-dependent.

#Q. Define Fatigue
Ans: Fatigue in humans is often described as a lack of energy and motivation, both physically and emotionally. It can be a response to physical and mental activities, and normally, it can be resolved with rest or reduced activity.
