Assorted Science Stuff
Things in an experiment that change.
What are variables?
Any push or pull that causes an object to move, stop, or change speed or direction.
What is force?
Light bulbs use electricity to create this type of energy.
What is radiant energy?
An organism's food, water, shelter, and space.
What is a habitat?
Steel, copper, iron, gold, and silver are examples of these because they allow electrical energy to move easily through materials.
What are conductors?
A bow that has been pulled back with an arrow resting on it, ready to release is an example of this type of energy
What is potential energy
The three kinds of energy electrical energy can be transformed into.
What is thermal (heat), radiant (light), mechanical (motion) energy?
Tiny, one-celled organisms from which plants like mosses and ferns reproduce.
What are spores?
A roller coaster car as it speeds downward along the track is an example of this type of energy.
What is kinetic energy?
Tiny fans in computers to keep them from overheating, and blenders with sharp motor-powered blades are examples of this type of energy.
What is mechanical energy?
Benjamin Franklin learned that lightning was a form of this kind of electricity. What kind of electricity?
What is static electricity?
The female part of the flower that is a stalk in the center of a flower.
What is the pistil?
Because of its small size and irregular orbit, Pluto is now considered this type of planet.
What is a dwarf planet?
Energy associated with light.
What is radiant energy?
Materials like rubber, plastic and wood which do not conduct electricity well because electrons do not easily move through them.
What is an insulator?
This causes the seasons as the Earth revolves around the sun.
What is the axial tilt?
Created when friction resists or stops motion.
What is heat?
Type of circuit that will light a bulb.
What is a closed circuit?
In photosynthesis, the warm rays of the sun power a chemical reaction in this part of the plant.
What are leaves?
All of the interrelated food chains in an ecosystem.
What is a food web?
