Scientific Structure
What is an organ?
Two or more tissues working together to complete a designated job within the body.
What two sytem's are involved in the action of breathing in and out?
Respiratory and Circulatory/Cardiovascular systems
What are the four main systems you use while exercising?
Cardiovascular/circulatory
Respiratory
Muscular
Skeletal
What does your evidence need to have to be considered a good piece of scientific evidence?
Accurate and detailed information about the topic.
What is the job of the kidneys?
What is a cell?
The smallest unit of life. Some folks call it the basic building block of life itself.
What happens to your heart rate when you go from resting to running in place?
It increases from low to high heart rate to maintain homeostasis.
What three organ systems are involved in digestion?
Digestion, Excretory and Circulatory/Cardiovascular systems
Which is a good example of evidence?
A. We saw a change in heart rate during the lab
B. The heart rate increased from 75 bpm to 110 bmp from trail 1 to trail 2
C. Figure 3 said so
B. The heart rate increased from 75 bpm to 110 bmp from trail 1 to trail 2
What two body systems are involved when your kidneys filter waste?
Excretory and Circulatory
What is an organ system?
When multiple different organs work together to preform a designated job and maintain homeostasis.
Why are the respiratory and circulatory systems considered the most imporant when you are excursing?
Both are required to maintain homeostasis/keeping you alive.
What organ system is in charge of telling all of the other organ systems what to do? Background character but the real star of the show!
Nervous system
Evidence needs to be detailed and accurate. What is an example of evidence that would support claim 1 on the board?
Answers will vary.
What is the job of the digestive system?
What is a tissue?
When two or more cells come together to complete a designated job within the body.
When we breathe in what are our lungs taking in and giving to the red blood cells?
Oxygen! This is essential for cellular respiration!
Skeletal and Muscular systems
What is an example of evidence that would reject/disprove claim 2 on the board?
Answers will vary
What system is the delivery team for the digestive and excretory systems?
Circulatory/Cardiovascular systems. The red blood cells are the delivery folks of the body!
What is the correct order for the scientific structure of living things?
CELLS form together to make TISSUES
TISSUES form together to make ORGANS
ORGANS form together to make ORGAN SYSTEMS
CELLS>TISSUES>ORGANS>ORGAN SYSTEMS
Draw out a line graph of your heart rate when doing these 4 activities. See board
A. Reading a book
B. Running the bases during kickball
C. Walking home after school
D. Sitting back down after walking around
Answer shown on board
Lowest to highest
A,D,C,B
What is the ultimate goal of all of the organ systems working together?
To maintain homeostasis, keeping the organism alive and healthy.
What would we need to change about claim 2 to make it accurate?
Many types
Should be organs not cells
When you eat food your body starts to digest the food down into useable molecules. Once the food is broken down it is sent all over the body to the cells that need the molecular vitamin/mineral. What two systems are involved in this process?
Digestive and Circulatory systems
