What does a scientist do?

Scientists conduct experiments and gather evidence. They use evidence to help them understand the world around us.

What kinds of things have you learned studying science before?

You can learn about animals and plants. You can also learn about planets and stars. You can learn about anything in the world around us.

How can you use your senses to make observations?

You can use your sense of sight to look for clues. You can also use your sense of touch to feel things. You can use your sense of hearing to listen for evidence and you can use your sense of smell to smell things. We should never taste things during a science experiment unless an adult tells us that it is safe to do so.

How can you collect evidence?

Scientists collect evidence by doing experiments and making observations with their senses.

Why are scientists important to the world?

Scientists can discover new things and create things to make the world a better place. They can help solve problems and help us understand the world around us.

How is a scientist like a detective?

Like detectives, scientists look for clues to help answer questions.

What information can scientists get from listening to wolves howling?

By listening to wolves howl, scientists can learn how many wolves there are or where they live.

How can scientists learn about the skin of a shark?

Scientists can touch a shark’s skin to learn if the skin is rough or smooth.

A fair test is when you do an experiment and only change one thing at a time. If you change more than one thing you will not know what caused the observations in your experiment.

If you could be any kind of scientist, which one would you be?

There are many different types of scientists. You might like to be a paleontologist who studies dinosaur bones. Or you might want to be a marine biologist who studies sea creatures. A chemist studies chemicals and all the neat things they can do.
