| Ways people harm ecosystems | littering, throwing garbage to oceans, starting fires, smoking, killing animals, cutting trees. |

| Insulator | an object that does not conduct heat well |

| pitch | how high or low the sound is |
| opaque objects | don't let light through |

| Producers, consumers, and decomposers | food chains starts with producers, plants produce their own food, then the animals eat the plants, and decomposers eat dead plants & animals, releasing nutrients into the soil. |
| ways animals defend themselves | running away, hiding in caves, changing color, and mimicry |
| Fossils are formed | organisms die, skin decomposes and hard parts are buried by sediments that turn to rocks. When the earth moves, they move up and scientists find them |

| gold and diamonds are used to | make jewelry |
| copper is used to | make coins |
| ways to use energy | cook food, power cars, see at night, watch TV, and heat water |
| ways to conserve energy | use blanket instead of heater, open curtains during the day, turn off water when brushing your teeth, turn off lights and AC when not in use, use bicycle instead of car |
| People hear sound | when vibrations travel through air to your ears causing your eardrums to vibrate |
| Rainbows are formed | rain + sun and water drops act like prisms breaking white light into many colors |
