Experimental Design
A safe number of trails to have in an experiment.
What is 10 trials?
BONUS: Why or Why not?
True.
All blood is red because it is rich in iron.
What is the function of the digestive system?
into unimportant parts to remove from the body.
Defender of the respiratory system that traps dirt and dust. Lines the respiratory tract.
What is mucus?
Which of the following is NOT a female scientist we studied?
Rosalind Franklin
Chein Wu
Margaret Mead
Tu You You
Elizabeth Blackwell
Tu You You
What is the dependent variable?
These are the four chambers of the human heart.
Right atrium. Left atrium. Right ventricle. Left ventricle.
Name the two types of Digestion.
Mechanical and Chemical digestion
What are the two muscles of respiration we learned?
Diaphragm and intercostal musscles
The work of this female scientist led to Watson and Crick to learn that DNA was a double helix.
Who is Rosalind Franklin?
The format used to write a hypothesis. (3 parts for full points).
What is "If [I.V.]..., then [D.V.]..., because [reasoning]."
100pts for If.. then...
100pts for I.V. and D.V.
100pts for reassoning
Define arteries, veins, and capillaries.
Arteries carry blood away from the heart.
Veins carry blood back to the heart.
Capillaries are tiny networks where arteries and veins meet.
The organ responsible for greatest amount of digestion and absorption.
What is the small intestine?
What is the function of the respiratory system? What is the term to describe this?
Pulls in air to deliver oxygen to blood and gets rid of carbon dioxide waste from the body. AKA gas exchange.
This physicist (scientist who studies physics) was the first woman to win a Nobel prize, first and only person in history to win 2 Nobel prizes in different sciences, and she studied radium.
Who is Marie Curie?
What is the difference between a constant and a control?
A Constant remains unchanged for all parts of the experiment and stays the same from beginning until end
A Control is the part that remains in its 'natural' state, and may change throughout the experiment.
The type of blood carried by the pulmonary artery.
Deoxygenated.
Name 4 organs responsible for chemical digestion and how. Give the organ name and type of chemical.
Mouth - Saliva breaks down sugar/starch
Stomach - Gastric juices
Small Intestine/Liver - Bile
Pancreas - pancreatic juices, insulin
Define the organ where gas exchange actually occurs.
HINT: Not the lungs
Alveoli: tiny, thin-walled air sacs at the ends of the lungs that come in contact with capillaries delivering deoxygenated blood
This scientist and her team coined the term 'debug' while working on Mark II. What happened that made them use this term?
Who is Grace Hopper?
They found an actual moth inside the computer that caused the program to glitch.
Compare qualitative and quantitative data. What are they and which one is more reliable?
Qualitative: described with words and depends on observer
Quantitative: described with numbers and measurements.
Quantitative is more reliable.
Describe the pathway of blood through the heart.
Blood enters right atrium via vena cava, moves to right ventricle, leaves through pulmonary artery to lungs, enters heart via pulmonary vein to the left atrium. Moves to the right ventricle and is pumped to the body through the aorta.
The hormone that tells the body to break down sugar. Secreted by pancreas.
What is insulin?
Describe the pathway of oxygen being inhaled to the blood through carbon dioxide being exhaled.
Nasal cavity and mouth, pharynx, larynx, trachea, bronchial tree (left and right bronchi), inside the lungs to alveoli and capillaries.
Oxygen delivered to blood and carbon dioxide picked up from blood to be exhaled.
This engineer and physician was the first African American woman admitted to NASA's astronaut program and became the first African American woman in space aboard the Space Shuttle Endeavour.
Who is Mae Jemison?
