Santa's Scientific Method
This is the first step of the scientific method, when you notice something in the world.
What is making an observation?
This type of variable is changed on purpose by the scientist.
What is the independent variable?
This is the basic unit of structure and function in all living things.
What is a cell?
This body system is responsible for pumping blood throughout the body.
What is the circulatory system?
The gas that plants take in to perform photosynthesis.
What is carbon dioxide?
Bonus 1000 points: Name 5 Christmas movies in 20 seconds.
A testable prediction in an experiment.
What is a hypothesis?
Bonus: 300 points Sing Jingle Bells
This variable is the one that is measured or observed.
What is the dependent variable?
The cell organelle known as the “brain” or control center.
What is the nucleus?
The system that helps you breathe in oxygen and release carbon dioxide.
What is the respiratory system?
Bonus 200 points: What organs are part of the respiratory system?
The sugar plants make during photosynthesis.
What is glucose?
The step where you record measurable information during an experiment.
What is collecting data?
Variables that must stay the same in an experiment.
What are constants (or controlled variables)?
Bonus 500 points: Name 10 Christmas songs in 30 seconds.
Plant cells have this rigid outer layer that animal cells do not.
What is the cell wall?
This system includes the brain and spinal cord.
What is the nervous system?
The green pigment that captures sunlight.
What is chlorophyll?
After analyzing your results, you write this final summary explaining what you discovered.
What is a conclusion?
In an experiment testing how sunlight affects plant growth, this is the dependent variable.
What is the plant’s growth (height or mass)?
These organelles convert food into usable energy for the cell.
What are mitochondria?
Bonus 400 points: Name all of Santa's reindeer
Bones, cartilage, and ligaments are part of this system.
What is the skeletal system?
This is the organelle where photosynthesis happens.
What are chloroplasts?
This is the term for repeating an experiment to increase accuracy.
What is a trial (or replication)?
Bonus 100: What is the minimum number of trials an experiment should have?
The group in an experiment that is used for comparison and does not receive the independent variable.
What is the control group?
These green organelles use sunlight to make food in plant cells.
What are chloroplasts?
Bonus 300 points: What is the organelle where cellular respiration occurs?
This system breaks down food so nutrients can be absorbed.
What is the digestive system?
The two main products of photosynthesis.
What are glucose and oxygen?
