Energy
Ability to cause motion or create change
What is Energy?
This is what a circuit must be for electricity to flow.
What is a closed circuit?
These animals have a backbone or spine.
What are vertebrates?
This plant structure absorbs water and nutrients like the human digestive system.
What are roots?
This is a test scientists do to answer a question or solve a problem.
What is an experiment?
Mechanical energy uses potential energy and what else
what is Kinetic energy?
This device opens and closes a circuit to control the flow of electricity.
What is a switch?
This is the largest group of invertebrates and includes insects, spiders, and crabs.
What are arthropods?
This plant structure moves water through the plant similar to how blood vessels move blood.
What is the stem?
This is an educated guess based on observations and prior knowledge.
What is a hypothesis?
sound energy is created how
What is produced by a vibrating object?
This part of a circuit provides the energy needed for electricity to flow.
What is a battery?
Fish, birds, reptiles, amphibians, and mammals are all types of these animals.
What are vertebrate groups?
These plant parts make food using sunlight, similar to how humans get energy from food.
What are leaves?
This variable stays the same during an experiment to keep it fair.
What are controlled variables (constants)?
produced when on object rubs against another
What is thermal energy?
When a circuit is broken or incomplete, electricity cannot flow.
what is an open circuit?
This group of vertebrates has hair or fur and feeds milk to their young.
What are mammals?
This human body system works like plant stems to move materials throughout the organism.
What is the circulatory system?
If two scientists test the same question and get similar results, this makes their findings more
What is reliable (or valid)?
what is heat energy?
These materials allow electricity to flow easily through them.
What are conductors?
These animals do NOT have a backbone.
What are invertebrates?
Both plants and humans have systems that transport materials needed for survival.
What is movement of water, nutrients, or oxygen (transport systems)?
Randall put earthworms into a box. He observed them moving toward the shade and away from the bright light. Based on this observation
What is the earthworms move away from the light?
