Energy
This type of energy is stored in food, batteries, or stretched rubber bands.
What is potential energy?
This property describes how easily something can be stretched or bent.
What is flexibility?
This state of matter has a fixed shape and volume, and the particles are packed tightly together.
What is a solid?
This is something humans can do to help protect the environment by reducing waste, like recycling paper and plastic.
What is recycling?
This type of environmental change happens when the Earth's temperature increases due to the burning of fossil fuels.
What is global warming?
When a moving object slows down, it is losing this type of energy.
What is kinetic energy?
The ability of a material to float on water is called this.
What is buoyancy?
In this state of matter, particles are spread out and move quickly, and it does not have a fixed shape.
What is a gas?
When humans cut down trees for wood or land, this is what happens to the environment.
What is deforestation?
When a body of water, like a lake or river, becomes polluted with waste or chemicals, this harmful process is called this.
What is water pollution?
This type of energy can be found in the movement of particles in a hot object.
What is thermal energy?
This is the property that describes how much mass is in a given volume of a substance.
What is density?
Water is an example of this state of matter, where particles are close together but can slide past one another.
What is a liquid?
This type of pollution happens when harmful chemicals from factories or vehicles are released into the air.
What is air pollution?
This happens when a large number of animals or plants are at risk of disappearing forever.
What is endangered?
This is the type of energy we use when we turn on a light or play music.
What is electrical energy?
This property describes how rough or smooth the surface of a material feels.
What is texture?
When a substance changes from a solid to a liquid, it is called this.
What is melting?
Humans can reduce their environmental impact by using this type of transportation, which doesn't rely on gasoline and produces less pollution.
What is biking or walking?
A series of connected food chains is called
What is a food web
The sun gives off this type of energy that helps plants grow and can also be turned into electricity with solar panels.
What is solar energy?
The hardest mineral is a
What is a diamond
This state of matter occurs at extremely high temperatures, and its particles move very fast.
What is plasma?
When people use cars, factories, or power plants, they release these harmful gases into the air, which can cause pollution.
What are carbon emissions?
When a large storm, like a hurricane or tornado, causes significant damage to the environment, this type of change is happening.
What is a natural disaster?
