This group in an experiment is essential because it provides data for comparison
What is a Control Group
This organ pumps blood throughout the body.
What is the heart?
A physical feature or behavior that helps an organism survive in its environment
What is an adaptation?
An earthworm lacks a backbone, making it this type of animal.
What is an invertebrate?
This is collected during an investigation to be used as evidence.
What is data?
This is the primary reason scientists write down the steps of an experiment so others can do the exact same thing.
What is replication?
These two organs are responsible for breathing
Spines on a cactus or large fronds on a fern are examples of this specific type of adaptation.
What is a physical adaptation?
Birds and humans both have this type of support structure inside their bodies
What is an internal skeleton or an exoskeleton?
This vocabulary word describes a group of the same type of organism living in an area (e.g. a group of rabbits)
Population
Unlike an observational study, an experiment typically involves changing and testing one of these
What is a variable?
This organ helps filter waste from the blood.
What are the kidneys?
This type of adaptation involves an action an animal takes to survive, such as migration or hunting at night.
What is a behavioral adaptation?
A celery stalk transporting colored water to its leaves demonstrates the function of this plant part.
What is the stem?
In an experiment testing fertilizer, if you cannot confirm the fertilizer caused the growth, you likely forgot this group.
What is the Control Group?
If an investigation is replicable and consistently produces the same results, the evidence is considered to be this.
What is Reliable/accurate
This set of structures provides support for the human body, similar to a stem in a plant.
What is the skeleton?
If a panther's habitat shrinks and resources are limited, this is what will likely happen to the panther population.
Die, decrease
While some animals have internal skeletons, others, like insects or crabs, have this type of hard outer covering.
What is an exoskeleton?
If a student watches plants grow in a forest and measures their height without changing anything, they are doing an observational study, NOT one of these.
What is an experiment?
A student watching plants grow in a forest without interfering is called an experiment or an observation?
What is an observation?
These are three major organs involved in digestion.
Stomach, intestines, pancreas, liver.
The process describes how animals with helpful traits are able to survive and have babies, while those without the traits often die
Natural Selection
Both a cactus's waxy coating and a fern's large leaves are adaptations suited to their specific “one of these"
What is an environment or habitat?
A bird relies on bones for support, but an earthworm is an invertebrate that uses its skin and these to keep its body shape.
What are muscles?
