A push or a pull on an object is called what?
What is a force?
These are the remains or traces of plants and animals that lived long ago.
What is a fossil?
These are features or behaviors that can be passed from parents to their offspring.
What are traits?
This is what we call the day-to-day condition of the air outside.
What is weather?
This is the process by which a caterpillar becomes a butterfly.
What is metamorphosis?
This force pulls objects toward the center of the Earth.
What is gravity?
A fossil of a fish found on top of a mountain tells scientists that the area was once covered by what?
What is an ocean or lake?
This word describes a trait you are born with, like eye color.
What is inherited?
This tool measures how hot or cold the air is.
What is a thermometer?
These two things do all plants and animals need to survive and complete their life cycles.
What are food and water?
This happens when two surfaces rub against each other and slow things down.
What is friction?
Over millions of years, these natural forces can change the Earth's surface and bury organisms to form fossils.
What are wind, water, and volcanic activity?
This term describes all the living things that an organism can inherit traits from.
What is ancestry?
This term describes the average weather conditions in an area over a long period of time.
What is climate?
In a frog’s life cycle, this stage comes right after the egg.
What is the tadpole?
Magnets have two ends. What are these ends called?
What are the north pole and south pole?
This word describes when an entire species of animals or plants has died out and no longer exists.
What is extinction?
Some animals have traits that help them survive better in their environment. This process over many generations is called what?
What is natural selection?
Clouds are made of this.
What are water molecules?
This part of a plant’s life cycle happens when pollen moves from one flower to another to help make seeds.
What is pollination?
Explain why a magnet can pull on a paperclip without touching it.
What is "Because magnets create an invisible magnetic field that pulls on certain metals like iron"?
Explain how studying fossils can help scientists learn about environments that existed a long time ago.
What is "Fossils show what kinds of plants and animals lived in an area, which tells scientists about the climate, water, and land that used to be there"?
Explain why a rabbit with white fur might survive better than a rabbit with brown fur in a snowy environment.
What is "Because the white fur helps the rabbit blend in with the snow, making it harder for predators to see it"?
Describe how the ocean can affect the climate of a nearby city.
What is "The ocean can make the climate of a nearby city cooler in the summer and warmer in the winter"?
Name the four stages of a butterfly’s life cycle in order.
What are egg, larva (caterpillar), pupa (chrysalis), and adult?
