| Hypothesis | an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true. |
| Inference | choosing the most likely explanation from the facts at hand. |
| Observation | an act of recognizing and noting a fact or occurrence often involving measurement with instruments. |
| Variables | any characteristics, number, or quantity that can be measured or counted. |
| Controls | an element that remains unchanged or unaffected by other variables. |
| Gravitational | the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field. |
| Chemical | the energy stored in the chemical bonds of a substance. |
| Elastic potential energy | energy stored as a result of applying a force to deform an elastic object. |
| Light- | a kind of kinetic energy with the ability to make types of light visible to human eyes. |
| Thermal | produced when a rise in temperature causes atoms and molecules to move faster and collide with each other |
| Sound | comes from vibrations moving through something. |
| electrical | the power an atom's charged particles have to cause an action or move an object. |
| mechanical kinetic energy | the energy of either an object in motion or the energy that is stored in objects by their position. |
| Energy transformations | energy changes from one form to another e.g. a light bulb: electrical energy to heat and light energy |
| Energy transfers | energy is transferred from one object to another e.g. kicking a ball: kinetic energy transferred from your foot to the ball |
| Organelle | A small structure in a cell that is surrounded by a membrane and has a specific function. |
| Eukaryotic | organisms whose cells contain a nucleus and other membrane-bound organelles |
| Prokaryotic | organisms whose cells lack a nucleus and other organelles. |
| Unicellular | an organism that consists of a single cell. |
| Multicellular | having, made up of, or involving more than one and usually many cells especially of living matter. |
| Specialization | focusing on a specific skill, activity, or production process |
