What are the three states of matter?
Solid, Liquid, and Gas
What are the 5 senses you use top observe properties of matter?
touch, taste, smell, sound, sight.
What is erosion?
The movement of land particles from one place to another.
what is weathering?
How will a higher temperature change the state of an ice cube?
It will melt, turning the ice into a liquid
What are three examples of observable properties of matter?
examples: texture, smell, color, shape, hardness.
what elements of nature can cause erosion?
rivers, waterfalls, oceans, wind
what two elements cause weathering?
water and wind
Which two states of matter can't hold their own shape?
Liquid and gas
What is a property of liquid?
can't hold its own shape, wet, and changes shape easily.
How can water cause erosion?
When water flows it carries pieces of land from one place to another.
How do wind and water cause weathering?
depending on the force of the water or wind it breaks down the particles so they are easier to carry to other places.
Name one example of a solid, liquid and a gas in our classroom.
examples:
solid - chair, floor, books, doors, cabinets.
liquid - water, coffee, any drinks
gas - the air in the room (oxygen)
What is a property of gas?
can be invisible, can't hold its own shape, moves freely through the air.
How can wind cause erosion?
5+ points if you can tell me where this happens the most.
High winds can blow pieces of land from one place to another.
(sand in the desert)
What will weather and erode land faster, a strong river or a small stream?
A strong river because it has more power
Tell me how you could turn an ice cube into a gas. What states of matter will it go through?
Heat ice and it will turn into a liquid. Keep heating the liquid and it will turn into a gas (water vapor).
What is a property of solids?
Holds its shape, does not change shape without force. Can be hard or soft.
How many waterfalls make The Niagara Falls?
Double points if you can name them
three: The Canadian Falls, American Falls and Bridal Veil Falls
How did weathering and erosion cause Niagara Falls to be created?
It eroded the cliff and all three waterfalls slowly moved backwards until they created on waterfall.
