What are animal hides and fur?
Why is it unsafe to walk on thin ice in the winter?
The ice might not support your weight and could break.
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.
What temperature does water boil at?

Why should we respect water in local environments?
To ensure clean water for people, animals, and plants, and to maintain a healthy ecosystem. We must take care of our water, just as it takes care of us.
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.
What are some ways we can show respect for the water?
Limit use (showers, brushing teeth), limit outdoor use (cleaning driveways, running the hose), do not litter, consider other perspectives
