What is a force?
A push or a pull
What do "like" magnetic poles do?
Like poles repel each other.
Name the three common states of matter.
What are solid, liquid, and gas?
What are the products in a chemical reaction?
What are the ending substances?
What type of light can cause skin cancer?

List two different types of energy.
Kinetic and Potential.
What do "opposite" magnetic poles do?
Opposite poles attract.
What is the law of conservation of energy in terms of thermal energy?
What is energy cannot be created or destroyed, only transformed?
What is the law of conservation of mass?
What is mass is neither created nor destroyed in a chemical reaction?
What part of skin can help prevent skin cancer?

Give two reasons why Australia has higher rates of skin cancer compared to Brazil.
There is something different about the sunlight over Australia, there is something different about the people's skin in Australia
What is a scientific model and how is it used in the study of energy?
A scientific model is a simplified representation of something that helps us understand it better, like how energy transforms.
How can someone increase the strength of a magnetic field in a system of two magnets?
Move the magnets AGAINST the magnetic force.
Explain the difference between temperature and thermal energy.
What is temperature measures average kinetic energy, while thermal energy is total kinetic energy?
What atoms make up rust?
2 iron (Fe), 3 oxygen (O)
