1. Student Activity: Read and take notes. How to share with students: These slides can be assigned digitally using an LMS (like Google Classroom), where students can work on their own slide decks via “Make a Copy for Each Student.” Each slide is set up with text boxes for students to type in. Please Note: Because Diffit resources can vary in length, be sure to check the formatting on each slide. Learn More: Please reach out with any questions or feedback. You can also learn more on our FAQ page , or get more resources at Diffit.me ! Suggested Lesson Flow: Preview Vocabulary with students prior to reading. A title image is available for you to use. Have students read Have students go through the Multiple Choice Questions . Have students complete the Short Answer Questions . Have students complete the Open Ended Questions Feel free to edit, remix, and use this resource however works best for you and your students!

2. Homeostasis Variables Mechanisms Negative feedback loops Regulating the state of balance that living organisms maintain in their bodies Homeostasis is important for your body to work properly. Review Vocabulary different factors or quantities that can be changed or measured processes or systems that are used to achieve a particular result a process where a change in a variable triggers a response that counteracts the initial change controlling or adjusting something to maintain a desired state or level Your body has different variables, like the pH of your blood and the levels of different ions. Your body maintains homeostasis through different mechanisms, like receptors, control centers, and effectors. Homeostasis is usually maintained through negative feedback loops, where your body detects changes and works to bring things back to normal. Your body regulates different factors, like blood sugar, blood pressure, and temperature, to keep everything in balance.

3. Homeostasis

4. Homeostasis is the state of balance that living organisms maintain in their bodies. It's like when your body keeps everything just right, like your temperature and fluid levels. Your body has different variables, like the pH of your blood and the levels of different ions, that it needs to keep within certain limits. Even when things change, like when you eat different foods or do different activities, your body still works hard to keep everything in balance. It does this through different mechanisms, like receptors that sense changes in the environment, control centers that set the limits for each variable, and effectors that bring things back to normal. One example of this is how your liver controls the levels of bile acids. Reading

5. Homeostasis is really important for your body to work properly. It's not just about keeping your temperature steady, but also things like the concentration of ions in your blood and the pH levels. If these things get too high or too low, you can get really sick. Your body works at many levels to maintain homeostasis, not just the whole body, but also individual cells and organs. For example, your stomach has a different pH than other organs, and each cell has different ion concentrations. Keeping everything in balance is key for your body to function well. Homeostasis is usually maintained through negative feedback loops, where your body detects changes and works to bring things back to normal. An example of this is when your body temperature gets too high, and your body works to bring it back down. Reading

6. Your body is always working to maintain homeostasis, even when things change. For example, when you exercise, your body temperature goes up, but your body works to bring it back down. And when you eat something, your blood glucose levels go up, but your body works to bring them back down too. This is all done through negative feedback loops, where your body detects changes and works to reverse them. It's like when your body uses sensors to detect changes, and then sends signals to different parts of your body to make the necessary changes. This helps to keep everything in balance and working properly. Homeostasis is really important for your body to stay healthy and function well. Reading

7. So, homeostasis is all about keeping your body in balance. It's like when your body makes changes to stay healthy and survive. Your body does this by regulating different factors, like blood sugar, blood pressure, and temperature. It's like when your body senses changes and reacts to bring things back to normal. This happens through different processes, like feedback control, where your body responds to changes and creates a new balance. An example of this is how a thermostat controls the temperature in a room. Your body does similar things, like regulating your energy levels and body temperature, to keep everything in balance. Homeostasis is really important for your body to keep working the right way and stay healthy. Reading

8. Multiple Choice Question A) Homeostasis is the state of balance that living organisms maintain in their bodies. It is important because it helps regulate factors like blood sugar, blood pressure, and temperature. B) Homeostasis is the process of maintaining a stable internal environment in the body. It is important because it helps prevent sickness and allows the body to function properly. C) Homeostasis is the ability of the body to adapt to changes in the environment. It is important because it helps the body survive in different conditions. D) Homeostasis is the process of keeping the body in balance. It is important because it helps maintain energy levels and body temperature. 1. What is homeostasis and why is it important for the body?

9. Multiple Choice Question A) The body maintains homeostasis through positive feedback loops, where the body detects changes and amplifies them. B) The body maintains homeostasis through negative feedback loops, where the body detects changes and works to reverse them. C) The body maintains homeostasis by constantly changing its internal environment to adapt to external conditions. D) The body maintains homeostasis by regulating only the whole body, not individual cells or organs. 2. How does the body maintain homeostasis?

10. Multiple Choice Question A) When you exercise, your body temperature goes up, but your body works to bring it back down. B) When you eat something, your blood glucose levels go up, but your body works to keep them high. C) When you sleep, your body shuts down all processes to conserve energy. D) When you are dehydrated, your body stops producing urine to conserve water. 3. Give an example of how the body maintains homeostasis.
