Biology
Plants get their energy from this source.
What is the sun?
The place where an organism lives and gets what it needs to survive.
What is a habitat?
This organ is about the size of your fist and works all day and night without stopping, even when you are asleep.
What is the heart?
The Sun is an example of one of these giant balls of hot gas that produce light and heat.
What is a star?
Earth moves in a path around the Sun, and this movement is called this.
What is orbiting?
An animal that feeds on another animal is called this.
What is a carnivore?
A habitat must provide these three basic things for organisms to survive.
What are food, water, and shelter?
Humans cannot breathe underwater because we do not have these organs that fish use to take oxygen from water.
What are gills?
Astronauts wear space suits in space for the same reason divers wear oxygen tanks when exploring deep underwater.
What is no oxygen to breathe?
This star is at the center of our solar system and provides the light and heat that makes life possible on Earth.
What is the Sun?
A living thing that can grow, reproduce, and respond to its environment.
What is an organism?
Forests, deserts, and oceans are examples of these.
What are habitats?
When you slip on a banana peel, it is harder to stop because the peel reduces this force between your shoe and the ground.
What is friction?
These are planets that orbit stars outside our solar system.
What are exoplanets?
Mercury, Venus, Earth, and Mars are part of this group of eight objects that orbit the Sun.
What are the planets
When the physical conditions of a habitat change, organisms must do this or they may not survive.
What is adapt.
This is the largest habitat on Earth, covering most of the planet’s surface.
What is the ocean?
This part of your body gives you goosebumps when you are cold or scared, even though it no longer helps humans stay warm like it did in our ancestors.
What is the skin
A galaxy is a very large system made up of billions of these, along with gas and dust, all held together by gravity.
What are stars?
This is the name of the galaxy that contains our solar system.
What is the Milky Way?
Thick fur on a polar bear and webbed feet on a duck are examples of this type of adaptation that involves body parts.
What is a structural adaptation?
When birds migrate to warmer places during winter to find food and survive, this is an example of this type of adaptation.
What is a behavioural adaptation?
This part of your body is the only one that cannot repair itself if it is damaged.
What are teeth
This force keeps the planets moving in their paths around the Sun instead of flying off into space.
What is gravity?
It must orbit a star, be round, and not share its orbit with other objects to be classified as this type of space object.
