It cannot be broken down
It can be reused without changing it
It breaks down naturally over time
It is made of plastic
Which of the following is the best example of a fair test?

Testing how fast sugar and salt dissolve in the same amount of hot water
Mixing oil and water in 2 different size jars
Using warm and cold water with different cups

A fixed amount of matter on Earth means:
Matter cannot be created or destroyed, only changed in form.
Matter is constantly increasing on Earth.
Matter disappears after use.
Matter is only found in living things.
Which of the following are examples of materials that can be reused at home?
(a)
Composting is a sustainable way to manage food waste because:
It reduces landfill waste and creates nutrient-rich soil.
It increases greenhouse gas emissions.
It wastes resources and energy.
It contaminates the environment.
In your solubility experiment, what was one variable you changed and one variable you kept the same?
The amount of solute was changed and the temperature was kept the same.
The temperature was changed and the type of solvent was kept the same.
The type of solvent was changed and the amount of solute was kept the same.
The amount of solute was changed and the type of solute was kept the same.
One thing you can learn from watching the plastic bottle life cycle video is:
How plastic bottles are recycled and reused
The history of plastic invention
How to make plastic bottles at home
The nutritional value of plastic bottles
Which of the following are ways students can help improve waste management at school?
Recycling materials, reducing waste, and composting organic matter
Throwing all waste in one bin, ignoring recycling, and using more plastic
Burning waste, littering, and wasting resources
Leaving waste management to janitors only

What does “a fixed amount of matter” on Earth mean?
It means the amount of matter on Earth doesn't increase or disappear. It just changes form or gets reused. Also means we can/will run out of various materials if not used sensibly.
It means new matter is constantly being created on Earth.
It means matter on Earth can disappear completely without a trace.
It means the amount of matter on Earth is always increasing due to space debris.
List two examples of materials that can be reused at home.
(a) (b)
Why is composting a sustainable way to manage food waste?
Composting turns food scraps into soil, which can be used again in gardens instead of going to landfill. (Must mention re-using)
Composting increases the amount of food waste in landfills.
Composting releases harmful chemicals into the air.
Composting makes food waste unusable for any other purpose.
In your solubility experiment, what was one variable kept the same and one variable you changed?
What is one thing you learned from watching the plastic bottle life cycle video? Give detail.
Imagine your school wants to improve its waste management. What are three ways students can help? Explain how each one helps the environment.
