- It is located in the temperate climate zone.
- Most of the trees in a boreal forest are evergreens and conifers
Describe a few key characteristics of a deciduous forest
- Exists in Europe and the United States where seasons change.

Which tool would be best to measure the volume of a small object?
graduated cylinder
Which tool would be best to measure the weight of a cat?
scale
What happens when you heat up ice?
the ice turns into water, a liquid
How are birds different from reptiles?
- Birds have a constant internal body temperature
- Birds have wings
- Birds have feathers
When a solid is heated, what does it usually change into before it becomes a gas?
liquid
Describe what happens at a cold front when a cold air mass meets a warm air mass
At cold front, cold air pushes under warm air. As the warm air rises, water vapor condenses to form clouds. Cold fronts move quickly, causing strong winds and heavy rains. Thunderstorms often occur along cold fronts. As the cold front passes, the sky clears and the weather gets cooler.
Describe the motion of atoms in a gas
Atoms move freely
Precipitation is water that comes from the sky. List the four main types of precipitation.
- Rain
- Snow
- Sleet
- Hail
How does snow form?
Water vapor freezes into crystals
How does rain form?
Tiny water droplets collide and form larger drops that fall to the ground
High pressure usually brings what type of weather?
dry and sunny weather
What tool is used to measure air pressure?
barometer

Name some characteristics common to reptiles
- Dry and scaly skin
- Eggs with tough, leathery shells
- Body temperature that changes with surroundings
How can a mammal be born?
- born and then crawl into a pouch
- born live
- hatch from an egg
Which groups of vertebrates have an internal body temperature that stays the same no matter how the temperature of the surroundings changes?
