Discussion Questions
- Before VideoWhat does a scientist do?ANSWER
Scientists conduct experiments and gather evidence. They use evidence to help them understand the world around us.
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.
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.
Scientists collect evidence by doing experiments and making observations with their senses.
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.
- After VideoHow is a scientist like a detective?ANSWER
Like detectives, scientists look for clues to help answer questions.
By listening to wolves howl, scientists can learn how many wolves there are or where they live.
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.
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.
