Heating and Cooling Changes
This process happens when ice warms up and changes from a solid into a liquid.
What is melting?
A push or a pull that can make an object move is called a __________.
What is a force?
This energy source in a circuit provides the power to make electricity flow.
What is a battery?
All living things grow and change over time. This pattern of changes is called a __________.
What is a life cycle?
________ describes what the air is like outside today—such as rainy, sunny, or windy.
Weather describes what the air is like outside today—such as rainy, sunny, or windy.
When water gets cold and turns into ice, this change is called __________.
What is freezing?
When you push a swing to make it move forward, you are using this type of force.
What is a push?
This object lights up when electric energy flows through a circuit.
What is a light bulb?
This stage of a butterfly’s life cycle comes after the caterpillar.
What is a chrysalis (pupa)?
The average weather in a place over many years is called its __________.
What is climate?
Melting ice and freezing water are changes that can be undone. These types of changes are called __________ changes.
What are reversible changes?
Magnets can make objects move without touching them. This is because of a force we cannot see called __________.
What is magnetic force?
Electric energy moves through wires in a circuit as this.
What is an electric current?
Humans, frogs, and plants all have something in common in their life cycles: they all __________.
What is grow and develop?
Temperature and rainfall are examples of this information that scientists collect to learn about weather and climate.
What is weather data?
Baking a cake or cooking an egg creates a new material that cannot change back. These are examples of __________ changes.
What are irreversible changes?
Rubbing a balloon on your hair and then sticking it to a wall shows this invisible force.
What is static electricity?
A circuit must be complete, or __________, for electric energy to transfer and make a bulb light.
What is closed?
A frog’s life cycle is different from a human’s because a frog changes from a tadpole into an adult. This big change is called __________.
What is metamorphosis?
A place that is usually very cold with lots of ice and snow has this type of climate.
What is a polar climate?
Scientists explain that heating and cooling can change matter, but some changes affect only the form while others change the matter itself. This idea helps us explain why some changes __________.
What is why some changes can be reversed and others cannot?
(Acceptable shorter response: “What is why some changes are reversible and some are not?”)
Magnets and static electricity show that some forces can affect objects even when the objects are __________.
What is not touching?
(or What is without contact?)
In this kind of circuit, each light bulb has its own path for electricity, so if one bulb goes out, the others can stay lit.
What is a parallel circuit?
Scientists compare life cycles of plants and animals to show that living things have __________ life cycles with different stages.
What are different?
(or What are unique?)
Scientists use patterns in temperature and precipitation to group places on Earth into these large climate types.
What are major climates?
(accept: What are climate regions?)
