Scientific Method
This is the first step of the scientific method.
What is make an observation
This is the definition of an independent variable.
What is something that you test or change.
This is the process of keeping things internally stable.
What is homeostasis
This is the thing that starts a chemical reaction.
What is a reactant
Carbon
This is what you do once you test a hypothesis.
What is draw conclusions.
What is a dependent variable?
The thing you measure based on what you changed.
This is the process by which living things give rise to off-spring.
What is reproduction.
This is what is used to reduce the energy needed in a biochemical reaction.
What is an enzyme?
Name 2 of the 4 types of organic compounds
What are carbohydrates, lipids, proteins, and nucleic acids.
This is the last step of the scientific method.
What is draw conclusions.
A scientist wants to know whether a pumpkin plant will produce larger pumpkins if the plant is fed milk or tea. This is the independent variable in this experiment.
What is the type of feed given to the plant.
A house plant grows on an angle towards the sunny window. This is an example of what characteristic of life.
What is responds to the environment.
This is the type of reaction that produces heat (aka gives heat off)
What is exothermic reaction (or for biochemical- catabolic reaction).
Enzymes and antibodies are examples of what type of organic compound?
What are proteins
True or false: A sample that is larger is more likely to be accurate than a smaller sample
TRUE
A scientist wants to know whether a pumpkin plant will produce larger pumpkins if the plant is fed milk or tea. This is the dependent variable in this experiment.
What is size of the pumpkins.
This is the basic structure of life.
What is a cell.
Vinegar is an example of what on the pH scale
What is an acid.
This forms cell membranes
What is lipids
This is why communicating your results are important.
It allows others to test your hypothesis. Communicating results can also help scientists to avoid some of the same types of errors in future observations and work.
This is an example of the control in this experiment.
What is (at least one of)
same location, same amount of sun, same amount of water, same soil, same temperature
These are 3 of the 6 characteristics of life.
What is
What is nucleic acids
