Energy & Circuits
This type of circuit provides only one path for electric charges to follow
Series Circuit
This is defined as a push or a pull that causes movement or a change in an object's shape
Force
This organ is responsible for processing information within the human body
Brain
This term refers to the total disappearance of an entire kind of living thing
Extinction
In an experiment to find out what causes cooling, a clean and dry towel serves as this important component
Control
This term describes a material, such as plastic, that does not carry electricity
Insulator
These types of forces are equal in size and opposite in direction, resulting in no change in motion
Balanced forces
This human body system is most similar to a plant's vascular system because it transports nutrients throughout the organism
Circulatory System
This is the practice of protecting ecosystems and the organisms that live within them
Conservation
Based on data from 50 seeds, this is the number of seeds that sprouted when given no water.
Zero
When a candle burns, this type of energy is transformed into thermal and light energy
Chemical Energy
This is a force of attraction between two objects, even if those objects are not touching
gravity
These specific parts of the body have thin walls that allow oxygen to pass through into the bloodstream
Capillaries
These are harmful substances that find their way into the air, ground, and water
Pollution
If a nail makes a bulb glow "very bright" and a crayon makes it "dim," this object is the superior electrical conductor
Nail
In a circuit where all bulbs are lit, if the first bulb (Bulb A) in a series circuit burns out, this happens to the remaining bulbs
They all stop shining
This unbalanced force between bicycle tires and the ground causes a coasting bike to eventually stop
friction
What are the four digestive system organs in order of how food is traveling through them?
esophagus, stomach, small intestine, and large intestine
This is the most important reason for a population, like zebras, to have individual variations
ensuring at least some individuals survive if the environment changes
Students found that less force was needed to move a weight on a wet surface compared to a dry one because of a change in this
Friction
A hydroelectric dam uses the flow of water through turbines and generators to create this useful energy transformation
transforming mechanical/kinetic energy into electrical energy
If an object is traveling in a straight line in space and no forces are affecting it, this will happen to its motion
it will continue in the same direction at the same speed
These are two ways a human skeletal system and an insect’s exoskeleton are compared. (One similarity, one difference)
S: provide support and protection.
D: One is inside, the other is outside
This is why Florida beach mice living inland are usually darker than those living on sandy beaches
they have adapted to their specific environment
If a force (F) is applied to a block and it does not move, this statement regarding the applied force and friction (Ff) is true
F and Ff are equal
