What are the three states of matter?
What is solid, liquid, and gas?
What is the process of changing from a solid to a liquid called?
What is melting?
What is the process called when water turns into vapor?
Evaporation
Name a natural material used by First Nations, Métis, or Inuit communities for clothing.
What are animal hides and fur?
Burning is an example of what kind of change?
Irreversible
What state of matter takes the shape of its container and has particles that move around a little bit?
What is liquid?
What do we call a change in matter that cannot be undone, like cooking an egg?
What is a permanent/irreversible change?
What happens during condensation?
Water vapor cools and turns into liquid droplets, forming clouds.
Why is it important to use natural materials respectfully?
We need to protect the land and its resources, as they are limited. And we want to maintain balance and harmony.
Melting chocolate is an example of what kind of change?
Reversible
Which state of matter has no definite shape and fast moving particles?
What is gas?
What temperature does water freeze at in degrees Celsius?
What stage of the water cycle happens when water falls to the ground as rain, snow, or hail?
What is precipitation?
Explain the difference between natural and processed materials.
Natural materials come from the earth and have not been changed. Processed materials are created using natural and man made materials through making changes.
True or False. Changes to some mixed materials can be reversed by evaporation.
True
Which state of matter has particles that are packed tightly together and vibrate in place?
What is solid?
Name a reversible change in matter.
What is melting ice or freezing water (butter/chocolate)?
Name the stage in the water cycle where water collects in lakes, rivers, or oceans.
What is collection?
Name a processed material and the natural material it is made from.
Ms. Carlsen will let you know if it is right :)
True or False?
Reversible change are changes that can be undone without any permanent damage
True
Give an example of a material that can exist in all three states of matter.
What is water as liquid, ice as solid, and steam as gas?
Compare evaporation and condensation (think about what state the water is currently in and changing to for each process).
Evaporation is when a liquid changes to a gas, and condensation is when a gas changes to a liquid.
Why is the water cycle important for life on Earth?
Ms. Bennett decides if she likes your answer!! (drinking water, supports the plant and animal life)
Explain the process for making rubber.
Special trees produce sap that is collected and transformed into rubber, which is stretched and chemically treated, then shipped to other places to be made into things like tires, boots, toys, etc.
True or False
Burning wood is a reversible change
False
