| Date artifacts | Scientists use many methods to do this. |
| Inductive reasoning | Uses specific information or facts to make a conclusion |
| Greenhouse gases | This is needed to make the planet warm, but too much produces global warming |
| Induced an electrical current | This is what Michael Faraday did when he moved a magnet back and forth inside a wire. |
| Noble gases | These elements are inert because their outer shells are completely full. |
| Cohesion | The reason water molecules pool together on a flat surface. |
| React | What happens to elements when their outer shells are ALMOST full. |
| Gravitons | A massless particle scientists believe causes gravity; yet, it has never actually been seen or detected |
| Water | This becomes less dense when it freezes and it also expands. |
| Natural selection | This is triggered in nature when animals adapt to their environment |
| Artificial selection | This is triggered in nature when humans do something to change animals in their environment |
| Arthropods | Named by scientists in the 1990s although Charles Walcott discovered them (unnamed) in 1910. |
| Fossil bed | An area of land that contains fossils |
| Cambrian period | A time that supposedly last from 530-520 million years ago |
| the Smithsonian Institute | The place in Washington D.C. were millions of artifacts may be stored away |
| Radiometric dating | When the age of an item is determined with the use of radioactivity. |
| Magicicada | This emerges every 13-17 years by the millions in Illinois |
| Louis Pausteur | This is the first scientist to theorize that microorganisms cause illness. |
| Pausteurization | The heating process that kills microorganisms |
| Autonomy | The freedom of choice |
| Gene therapy | Treatment for an illness involving the use of genes |
| Visible spectrum | Electric magnetic wave group that can be seen |
| Weak Force | Occurs at a subatomic level and causes radioactive decay and happens with a charge OR without |
| Gravity | A fundamental force that has very little strength, but occurs at vast distances (far) between two masses |
| Strong Force | Occurs at a subatomic level and holds like charged particles together |
| Electromagnetic Force | Occurs across a great distance between two charged masses |
| Vaporize | To change from a solid to a gas |
| Anthocyanin | A chemical in cabbage that may be used to indicate PH |
| Bouyancy | The ability to float in a liquid |
| Centrosome | These control the fibers that help divide a cell |
| Centromere | The center of the X in a chromosome |
| Mitosis | Cell division |
| Cytokinesis | The final stage of cell division |
| Nobel Prize | What Richard Axel and Linda Buck won for their research with the cell |
