Variables
These are the three types of variables in every experiment.
What are the independent variable, the dependent variable, and the constants or control variables.
This is the definition of cellular respiration.
These are the organs of the repiratory system.
What are the mouth/nose, trachea, bronchi, lungs, bronchioles, alveoli, lungs, capillaries, and diaphragm.
These are the parts of the circulatory system.
What are the heart, blood, and blood vessels?
This is the best way for us to write hypothesis in the 7th grade. (I am looking for a verbal formula.)
What is an 'If ... then ...' statement?
This is the variable that goes after 'If' in an 'If ... then ...' hypothesis.
What is the independent variable?
What is to bring oxygen into the body for use during cellular respiration and excrete carbon dioxide from the body, which is a waste product from cellular respiration?
These are the three type of blood vessels.
What are arteries, veins, and capillaries?
This is the difference between respiration and respiratory system.
What is the respiratory system brings oxygen into the body and respiration (also called cellular respiration) is when the body combines that oxygen with glucose in the mitochondria to make energy?
This is the number of independent variables that you can have in an experiment.
What is one?
What is go up?
This is the relationship between the respiratory system and the musculoskeletal system. (Be specific.)
What is the diaphragm which lets you breathe is a muscle?
This is the purpose of the circulatory system.
What is to move nutrients, gasses, and waste through the body?
This is the way that oxygen gets from blood into cells for use in cellular respiration. (Think WAAAYYYY back from early in Q2.)
What is diffusion?
This is the variable that the scientist manipulates.
What is the independent variable?
When your body works harder you would expect to see the rate of cellular respiration do this.
What is go up?
This is where the oxygen gets from the lungs to the bloodstream. (Be specific. You must include BOTH parts.)
What is through the alveoli into blood in the capillaries?
This is the definition for pulse rate. (Be specific)
What is the number of times your heart beats in a minute?
This is the problem with the following experimental setup:
A student wants to test the effect of music on worm growth. They keep a bin of worms outside in the school yard with no music. They keep a second bin inside where the worms can listen to Kendrick Lamar 24 hours a day.
What is there are too many independent variables?
This is the variable that you measure.
What is the dependent variable?
This is what happens to your blood oxygen during exersion and WHY it happens.
What is goes down because the rate of cellular respiration increases?
What is the respiratory system brings oxygen into the body and the circulatory system carriers it to the cells to do cellular respiration?
These are the units for to measure your pulse rate.
What is BPM?
This is what you must include in all evidence that you derive from a chart or a graph.
WHAT ARE NUMBERS?
