Homeostasis Investigation
Description: The point of this project was to learn about homeostasis and what it does to keep us alive. We learned about how heart rate changes when doing different activities. We did an expansive number of tests and we organized our data into an online poster and our own article to show our data.
Concepts:
- Homeostasis: Homeostasis is the state the body needs to be in order to maintain stable condition. It is necessary to survive. Our project was about homeostasis.
- Heart Rate/BPM: BPM is the speed at which your heart beats. BPM stands for beats for minute. You find your beats per minute by counting how many times your heart beats in a minute. This is how we got our data.
- Heart: The heart is an organ that pumps blood and oxygen around your body. It is important because it circulates blood and oxygen through your body.
- Circulatory System: The circulatory system circulates blood and oxygen throughout your body. It includes the heart, blood, and blood vessels.
- Feedback Loop: A feedback loop is a self regulating system that your body uses to help maintain homeostasis. An input causes your body to have a reaction, which produces an output. In a negative feedback loop the output causes the input to decrease. In a positive feedback loop the output causes the input to increase.
- Medulla: The medulla is the part of your brain that controls the autonomic nervous system.
- Cellular Respiration: This process causes your body to use oxygen to turn glucose into ATP for your body to use as energy.
- Control: The control is the baseline that you can compare your data to.
- Independent Variable: This is the part of the experiment that never changes.
- Dependent Variable: This is the part of the experiment that changes depending on the independent variable.
Reflection:
I feel this project went very well. We got a lot of data that supported our claims about how homeostasis.
