Contact Forces
This is a push or a pull on an object.
What is a push or a pull?
This occurs when the Moon passes directly between the Sun and Earth. When this happens, the Moon blocks the Sun's light and casts a giant shadow on our planet.
What is a solar eclipse?
These are the differences in traits.
What are variations?
A characteristic that helps an organism survive and reproduce in its environment is called this.
What is adaptation?
The minimum number of evidence for any CER.
What is 3 pieces of evidence?
This is the amount of "stuff" or matter in an object.
What is mass?
This imaginary line runs through the North and South Poles and Earth rotates around it.
What is the Earth's axis?
The amount of genetic information offspring get from each parnet.
What is 50%?
Organisms that are most likely to survive.
What are best adapted or survival of the fittest?
This is a visual representation of data.
What is a graph?
The energy an object has because of its motion is called this.
What is Kinetic?
The hemisphere tilted toward the Sun receives more direct sunlight and experiences this season.
What is summer?
The way an individual looks for a specific trait.
What is phenotype?
This scientist developed the theory of natural selection after observing organisms in nature.
Who is Charles Darwin?
This part of a CER explains the claim.
What is reasoning?
This famous scientist developed the three laws of motion and explained how gravity affects objects
Who is Isaac Newton?
The main reason Earth experiences seasons is because of this feature of Earth.
What is Earth's tilted axis?
Having different alleles for a gene.
What is heterozygous?
Natural Selection causes this? (Think Peppered Moth or Galapagos Finches)
What is change in population?
The more of these in an experiment, the more valid the data is considered.
What are trials?
This is a contact force due to interaction between surfaces in contact and is produced by the bumps (roughness) on surfaces as they push against each other.
What is Friction?
The amount of the moon that is always lit by the sun.
What is half?
An organized representation (model) of biological relationships.
What is a pedigree?
This is the process by which organisms with helpful traits are more likely to survive and reproduce.
What is natural selection?
The number of independent or manipulated variables in a given experiment.
What is one?
