is for Atmosphere

The Earth's atmosphere helps us be protected from space objects and radiation.

is for Barometer

A barometer measures air pressure.

is for Circuits

Circuits have a battery (power source), wire (thing that connects it), and the object receiving the power. They might have a switch also.

is for DNA (Deoxyribonucleic Acid)

DNA (Deoxyribonucleic Acid) is the molecule that contains genetic information for organisms. 

is for Euglena

Euglena is a single-celled eukaryote, is a protist that uses photosynthesis to get it's food.

is for Fronts

A front is a boundary that separates different air masses. 

There are for different types of fronts:

- Cold Front

- Warm Front

- Occluded Front

- Stationary Front

is for Genetics

Genetics is the branch of biology that deals with the study of genes and heredity in organisms. 

is for Human Body Systems

There is many (about 12) main human body systems, which work together to help us grow, reproduce, and survive. Examples are, respiratory, digestive, muscular, nervous, urinary, skeletal, immune, reproductive, etc.

is for Incomplete Dominance

An allele (which is a form of a gene), can either be dominant or recessive. Dominant means that it shows and recessive means that it hides. So, in

incomplete dominance, neither allele is dominant, causing the result to be of the two blended together.

is for Joule

Joule is a SI unit of energy and it is used to describe work (and energy). It is written as J. 

is for Kinetic Energy

Kinetic energy is the energy when an object is in motion.

is for Lever

A lever is one of the six simple machines that  makes the work easier by changing the amount of input force or the direction of the input force. There are three different classes.

is for Mitosis

In cell biology, mitosis is the cell division with the result in two identical daughter cells, each with the same number of chromosomes.

is for Newton's Three Laws of Motion

Newton's three laws of motion are three statements, 

great scientist, Isaac Newton concluded to after doing experiments and research.

is for Organism

An organism is any living thing that can do basic things such as, grow, adapt, reproduce, and maintain homeostasis (which is the tendency to relatively stable body temperature).

is for Punnett Square

Punnett squares are square diagrams that are used to predict the genotypes of a particular cross or breeding. They can determine the probability of an offspring having a particular genotype.
