100
Describe how to make an object magnetic.
What is rub the pole of a magnet on the end of the object in one direction.
100
What is the difference between a step-up and step-down transformer?
What is a step-up transformer increases voltage while decreasing current and a step-down transformer decreases voltage while increasing current.
100
How many options does a dichotomous key have?
What is two options.
100
Describe what natural selection is.
What is survival of the fittest.
100
Why would having a variety of organisms be a good thing for an environment.
It allows for predator prey relationships and the environment to thrive with a high biodiversity.
200
What are the three ways to demagnetize a magnet?
What is drop/hit a magnet, place it in very warm temperatures, place it in an magnetic field that is opposite and stronger than its own.
200
Describe what portion of the electromagnet becomes magnetic. Why?
What is the iron nail because of the electric current that generates a magnetic field from the solenoid.
200
What is the science of describing, naming, and classifying organisms?
What is taxonomy
200
Why do you think animals would need to adapt to their environments?
What is so they can survive.
200
What is the difference between asexual and sexual reproduction?
What is asexual reproduction has one parent and sexual reproduction has two parents.
300
Where is the strongest part of a magnet? Where is the weakest part of a magnet?
What is the strongest part is at the poles. The weakest part is in the middle.
300
Draw and label the parts of an electromagnet. Be sure to include the solenoid.
What is see pictures.
300
Describe how you can use a dichotomous key.
What is you look at your object or organism that you are trying to classify and see which of the two options it meets, you then go to the next question or statement that the first question told you to go to, and you keep going through these steps until you have identified your object/organism.
300
Describe what an adaptation is.
What is something that helps an organism to change in order to survive.
300
Describe how you can tell what the prey is while looking at a predator prey graph.
What is the prey will always have a higher value than the predator.
400
How are a bar magnet's magnetic field and the earth's magnetic field similar?
What is they are both strongest at the poles and weakest at the center. They both are permanent magnets.
400
What is electromagnetic induction?
What is the changing of magnetic fields to create an electric current.
400
In a scientific name, where is the genus located and where is the species located?
What is the genus is first, then the species is second.
400
What do you think would be a physical adaptation of an owl?
What is answers will vary.
400
What is the difference between internal and external fertilization?
What is internal fertilization happens within the body and external fertilization happens outside the body.
500
How is a ferromagnet different from a temporary magnet?
What is a ferromagnet is harder to magnetize but it is harder to lose its magnetism. A temporary magnet is easier to magnetize but loses its magnetism easily.
500
What is the difference between an electric motor and an electric generator?
What is an electric motor turns electrical energy to mechanical energy. An electric generator turns mechanical energy to electrical energy.
500
What are some characteristics that you can use to make a dichotomous key for a dolphin, shark, and goldfish?
What is answers will vary.
500
Describe the four steps of natural selection.
What is Overproduction, Inherited Variation, Struggle to Survive,Successful Reproduction
500
Describe what bias is and how it can affect the results of a science experiment.
Bias is when you add in your own thoughts or opinions into something. It can make your experiment invalid.
