In this project we had to model different body systems with a physical representation. We used our skills that we learned in freshman STEM and applied them to build our models.
This is our representation of the nervous system in regular speed.
What the Model Represents:
The model represents the tiny nerves in your hand transmits signals up the spinal cord to your brain to be processed into an impulse. It goes back down the spinal cord to the tiny nerves in your hand to send the message to your muscles, which causes the reflex. The dominoes represent the tiny nerves in your hand and arm. The pulley shows how the spinal cord transmits the signal to the brain to process. The cup (brain) turns over because it processed the signal. The marble is released to represent the impulse the brain gives out. It travels down the spinal cord (ramp) to the smaller nerves in your arm and hand. The message is sent to the muscles which causes the reflex.
This is our representation of the immune system.
What the Model Represents:
The acetone represents the pathogens trying to enter the system. The pathogens are entering your system when the acetone is dripping down the tube. The candle represents the White Blood Cells. When the white blood cells surround the pathogens the pathogens begin to leave your system. When the acetone catches on fire it represents the immune system removing the pathogen from the system.
This is our representation of how the Immune and Nervous system work together.
What the Model Represents:
The Nervous gets an impulse to the brain which sends another impulse to the white blood cells/antibodies in the immune system to fight the pathogens. In our model, we used the Nervous System board and added pins and a balloon to the end of it. This way, when the Nervous System board is activated, it makes the balloon hit the needles, popping the balloon. This represents the immune system (needles) being activated by the nervous system when any diseases (balloon) try to infect the body.
Content:
Nervous System:
Nervous System:
Coordinates the body’s response to changes in its internal and external environments and sends pulses/ signals to organs
Dendrites:
They are spread throughout the body and carry impulses from environment or from other neurons towards the cell body
Axons:
They are fibers that carry impulses away from the cell body
Nerves:
They are axons and dendrites that are clustered into bundles
Major organs:
The brain, spinal cord, and the peripheral nerves
Neurons:
They are a specialized cell transmitting nerve impulses
Sensory:
They carry signals from sense organs to the spinal cord to the brain
Motor:
They carry impulses from brain to the spinal cord muscle and glands
Inter-neurons:
They connect sensory and motor to carry impulses between them
Immune System:
Immune System:
Defense system against invaders
Immune Response:
The immune system attacks organisms and substances that invade body systems and cause diseases.
White Blood Cells:
They are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
Tissues:
Each is made of specialized cells that are grouped together according to structure and function.
Lymphatic Tissues:
includes the lymph nodes, spleen, tonsils, adenoids and the thymus.
Organs:
A part of an organism that is typically self-contained and has a specific vital function.
Reflection:
One peak in this project was we all were efficient which helped us finish early. Another peak was we had a detailed plan which helped us stay on task and finish early.
One pit in this project was that we all worked individually and we did not work as a group. Another pit was we all followed the plan, but we never checked in on each other so we never knew what anyone else was doing.
