| Question | Answer |
|---|---|
| what is matter | something that takes up space |
| what are the three states of matter | solid liquid gas |
| what properties does matter have | volume shape mass |
| what is mass | the amount of matter an object has |
| what is volume | amount of space matter takes up |
| what is a solid | it has a definite shape, mass and volume |
| name some solid objects | tree, chair, couch, bed, tv, people |
| What are solids made up of? | Tiny particles called atoms that are very close together. they bond together and don't change shape |
| what is a liquid? | it does not have a definite shape but do have definite volume and mass. |
| are liquid atoms close together? | yes but they can move around |
| do liquids take the shape of their container? | yes they change shape based on container |
| does gas have a definite shape or volume? | no a gas spreads out everywhere |
| if a gas Is not in a container what will happen? | it will spread out indefinitely (forever) |
| are atoms in a gas spread out or close together? | spread out and move freely |
| What are some things made up of gas? | air, the sun, clouds, carbon dioxide, natural gas, steam, helium |
| what is a physical property of matter? | anything you can observe about matter by using one of your senses |
| how many senses do you have? | 5 |
| What are the 5 senses? | smell, sight, taste, touch, hearing |
| What is density? | it is the mass of matter compared to its volume |
| how are solids alike? | All solids are made up of particles and stay the same shape |
| how are liquids and solids different? | solids have shapes that stay the same and liquids can change shapes |
| how are gases different than solids and liquids | Gases do not have volume or shape and liquids and solids do because their particles stay closer together |
| two different changes of state are | condensation and evaporation |
| What is condensation? | is a change of gas to a liquid |
| What is evaporation? | is when water moves in the air and becomes a gas |
| how are condensation and evaporation the same? | both are changes of state. |
| How are condensation and evaporation different? | Evaporation changes liquid to gas. Condensation changes gas to liquid. |
| what is a physical change? | change in matter that does not form new kinds of matter |
| what are some examples of physical change? | cutting paper, sharpen pencil, mixing cereal and fruit together, mixing up red beads with yellow beads |
| what is a chemical change? | a change that forms a different kind of matter |
| what are some examples of chemical change? | rusting, mixing flour, sugar and water to make dough, mixing lemons, sugar and water to make lemonade, |
| What is energy? | the ability to make something move or change |
| what are some examples of energy? | electric, wind, sound, water, |
| how is the energy you use to grow different from the energy seeds use to grow? | People need food to have energy to grow and plants need sun light |
| What is kinetic energy | the energy of motion |
| name some examples of kinetic energy | kid going down a slide, arrow flying through air, car moving, pedaling a bike |
| what is potential energy | energy of position |
| examples of potential energy are? | standing still, a stopped car, a book on a shelf, sitting at the top of a slide |
| how is the energy of a book sitting on a shelf different than a book falling? | a book on a shelf has potential energy (still) and book falling has kinetic energy (moving) |
| is mixing flour eggs and yeast into bread a physical or chemical change? | chemical (three things blend into one thing) |
| is metal rusting a physical or chemical change? | chemical (metal is reacting with air to change color) |
| is a loaf of bread cut into sliced bread a physical or chemical change? | physical |
| when a fresh apple becomes a rotten apple is that a physical or chemical change? | chemical the air is changing it |
