| sedimentary | Type of rock that has fossils in it. It forms when tiny pieces of rock are pressed down together by water pressure forming layers. |
| crest | The top of a wave. |
| osmosis | Water molecules move through a cell membrane from a high concentration to a low concentration. |
| integumentary | The body system made of skin, hair, and nails. |
| pollination | When pollen is carried by wind, animals, or insects from the anther of one flower to the stigman of another. |
| gene | A section of DNA on a chromosome that has instructions for a trait. |
| chloroplast | An organelle that plant cells have but animal cells do not. It captures sunlight for plants to use in photosynthesis. |
| vacuole | An organelle that stores water and other substances for the cell. |
| nucleus | The organelle that is in control of the cell. It contains the chromosome. |
| cytoplasm | Jelly-like material that is constantly flowing. It is between the cell membrane and the nucleus. |
| assistive engineering | Using science to create products to help people with physical disabilities. |
| carbon dioxide | A gas that plants need for photosynthesis. Animals exhale this gas as a waste product of cellular respiration. |
| pistil | The female organs of a flower which include the stigma, style, and ovary. |
| compound machine | A machine made up of two or more simple machines. |
| compaction and cementation | The processes that form sedimentary rock. |
| Moh's hardness scale | Diamond is a 10 and gypsum is a 2. Gypsum could not scratch a diamond. |
| cooling | The process that forms igneous rock. |
| divergent | Tectonic plates move away from each other at this type of plate boundary. This is where new sea floor is formed as magma rises up. |
| organelles | Cell parts |
| nervous | The brain and spinal cord are two of the organs in this body system. |
| double helix | The twisted shape of DNA. |
| recessive trait | A trait such as blue eyes that will not show up unless an offspring inherits the recessive gene from both parents. |
| luster | How shiny a mineral is. |
| streak | One of the properties used to classify minerals--a colored powder that is left behind when you scrape a mineral on a hard plate. |
