This is called the _____________. - Water Cycle, What are the four stages of the water cycle? - Evaporation, Condensation, Precipitation, Collection, Name the two types of materials. - Processed and natural materials, What is the temperature of the melting point of ice? - 0° Celsius, If water freezes it turns into this state of matter - Solid, Condensation means... - The water vapour condenses into water droplets (liquid)., Matter is described as... - Anything that has mass and takes up space., The three states of matter are called... - Solid, Liquid, Gas, Describe the particles of a liquid. - Loose particles that can still move around. Not tightly packed together., The state of matter for milk is... - Liquid, The state of matter for a chocolate bar is... - Solid, The state of matter for Helium is... - Gas, Reversible changes are... - Materials that can change states like ice cream, chocolate, candle wax., Irreversible or permanent changes are... - Unable to go back to its previous state. A new substance is made., Identify which beaker belongs to the three states of matter, Which state of matter does not take the shape of the container it's in? - Solids., Think of five examples of a natural material. - Think of natural resources taken directly from the land., Think of five examples of a processed material. - Think of materials that have gone through a process to become a new material. Usually, they are made to fix a problem., Describe some differences between the three states of matter. - Anything!, The boiling point of water is... - 100° Celsius, If a solid turns into a liquid it is... - Melting, Evaporation is the process of... - Liquid turning into gas. Like lake water turning into water vapour., The freezing point of water is... - 0° Celsius, Which state of matter has no definite shape and no definite volume? - Gas, Which state of matter has a definite volume, but not a definite shape? - Liquid, How is the water cycle an example of a reversible change? - It's a cycle! The water goes through the process of liquid and gas, over and over again. Turning from collected water, to water vapour, to precipitation, and back to collection., Precipitation means... - Rain, hail, snow, etc., Collections means... - Water that is collected on the surface of the Earth., Natural materials are... - Any resource that comes directly from the plants, animals, land, or sky., Processed materials are... - Produce from natural materials and do not occur in the natural world., A physical change is... - When a material looks different. E.g. folded, bent, cut, stirring, A chemical change is... - When a material changes into a new material. E.g. eggs, cake, burnt marshmallows, rusted roof, blue cheese, The particles are furthest apart in this state of matter... - Gas, All matter is made up of tiny ______________. - Particles, Particles in a ____________ have the strongest attraction. - Solid, Liquids will turn into solids when they are... (Heated or Cooled?) - Cooled, What does the boiling point of a liquid mean? - It's the temperature that it turns into a gas. Think of water boiling, the particles are jumping around and being released into water vapour., Why do people use windshield washer fluid instead of water? - Windshield washer fluid freezes at -96° Celsius while water freezes at 0° Celsius. It would just freeze again!, Different liquids have different freezing... - points., How does water freeze? - Water, a type of liquid, cools down to its freezing point at 0° Celsius. The particles stop moving around and have a higher level of attraction until they turn into a solid., When the temperature is 0° Celsius, what could happen? - Water freezes, freezing rain can happen, roads get icy, my ice cream doesn't melt!, Liquid water will freeze when the temperature is ___________ zero. - Below, Name three examples of a solid. - SOLIDS, Name three examples of a liquid. - LIQUIDS, Name three examples of a gas. - GAS (Oxygen, Hydrogen, Helium, Carbon Dioxide, Water vapour, , The _________ on Earth moves continuously in a cycle. - Water, The melting and freezing points of a substance are the _______ temperature. - same, Our science unit was all about.... - MATTER!, The indigenous peoples used this natural material to make medicine. - Plants, Name a way the Indigenous peoples used wood as a natural material. - Tipis, bows, arrows, tools.,
