Hello and welcome back to the Curious Kid podcast.

We are a few weeks into the new year.

And when a new year approaches, many people make New Year's resolutions.

healthier. I myself have resolved to exercise more and eat healthier this

year and I'm off to a pretty good start, just six weeks into the year. When people try to

eat healthier, they often consider calories and how many calories different foods have, or even

how many calories can be burned by different

exercises. But what is a calorie? We know that foods have calories, but do we know what calories

Nora is curious about calories.

Why are they important?

Thanks for the great podcast. Keep up the good work. Thanks so much for the awesome email. We can't wait to learn all about calories for Nora, Ben,

and Colby. As we will learn about more in a moment, you can burn calories by exercising. Some exercises burn more calories than others.

The question of the week is, which of the following exercises burns the most calories in

60 minutes, riding a bike leisurely, playing a competitive basketball game, playing a competitive

soccer game, bowling, or roller skating.
