- something that causes something else to happen
- reactant
- an organism that eats another organism
- consumer
- a change that you can see taking place physically, not a chemical.
- physical change
- it breaks easily (non metal)
- brittle
- an underground storage place for water, an underground lake.
- aquifer
- an organism that makes it's own food
- producer
- water that is found underground, no very different from an aquifer
- ground water
- has mass and takes up space
- matter
- ex. grass, grasshopper, bird, hawk
- food chain
- many atoms together
- compound
- it's flexible, not easily broken
- ductile
- an atom with a negative charge
- electron
- something that stays together but can be pounded on and not get broken..
- malleable
- a chart of elements/chemicals and their information
- periodic table
- the rate at which the food chain grows and functions
- trophic lever
- the cycle in which water goes from, evaporation, precipitation, condensation/transpiration.
- water cycle
- the control center of all cells.
- Nucleus
- an atom with 0 charge, it's neutral.
- neutron
- the after math of having a reactant.
- product
- the process in which bacteria from plants converts nitrogen (N, small 2) into usable nitrogen.
- nitrogen fixation
- converting nitrogen into a usable form. Nitrogen gets absorbed into the ground and gets into the plants, bacteria on the roots of the plants then convert the nitrogen into a usable form, an organism eats the plants and gets the nitrogen into their body, the nitrogen then exits the body of the organism by "waste".
- nitrogen cycle
- a hybrid of metals and non metals
- Metalloids
- a change that is by a chemical reaction
- chemical change
- something that conducts electricity, or has an easy transfer of energy/heat.
- metals
- an atom with a positive charge.
- proton
- 1.) all elements are made of atoms. 2.)Atoms of the same element are exactly alike. 3.) atoms of a different element are different properties. 4.) Atoms are not actually changed by a chemical reaction, just rearanged. 5.) Compounds are formed when atoms combine. 6.)compounds are defined but the number, type and proportion of atoms, matter cannot be created or destroyed.
- Atomic theory of matter
- it is brittle, non mattleable, and is a poor conductor of heat/electricity/energy.
- non metals
- issues that have something to do with the environment.
- environmental issues
- groups in the periodic table
- periods
