Lesson Transcript

You've probably heard of scientists, but what do they do? Well, scientists are people who love figuring out why things happen. You could be a scientist, too! Keep reading to learn more about scientists and how they perform their work.

Scientists Do Many Things

There are many different kinds of scientists, and they all do different things. Some like to learn about living organisms. They are called biologists. Others like to study rocks. We call them geologists. People who study animals are sometimes called zoologists - this is easy to remember because sometimes animals live in zoos.

Scientists are very curious people who like to solve problems. They solve these problems by doing science projects called experiments. What are some of these problems? Well, they can be about keeping our air clean or finding a way to cure people when they have certain diseases.

So what do scientists do specifically? Well, it all boils down to observing, measuring, and communicating. Let's take a look.

What Do Scientists Do?

Scientists observe things. Our senses can help us observe what is around us. Scientists use their senses when solving science problems. They use their eyes to spot details. They use their noses to detect if something is stinky. They use their hearing, touch, and even sense of taste.

Scientists measure things. Have you ever measured something with a ruler to see how long it is? Scientists do that. Have you ever stood on a scale? If so, you've measured your weight. If you've ever taken your temperature when you had the flu, you've measured how hot your body is using a thermometer. Scientists use scales, rulers, thermometers, and lots of other tools to measure things.

Scientists communicate their findings. We always want scientists to talk about their discoveries and share with others. They can tell other scientists, or they can tell people like you and me. It can be in the local news or in our science book.

Putting It All Together

Do you remember the three things a scientist does? They observe, measure, and communicate. You can do the same thing a scientist does. Let's take a look at this experiment.

Imagine you go outside, and you see a bunch of ants on the ground, bringing food from one place to another. You want to know where they're going and how fast they can do this. You decide to do an experiment with ants.

Ants are small, so you may go inside and grab a magnifying glass so you can see them better. With the magnifying glass you observe that the ants are all carrying the food to one place in an anthill.
