Why does your heart beat faster when you play basketball than when you are just seated in your science class?
Your heart beats faster for a combination of reasons.
Your heart's job is to move blood around your body
1a) Your blood does several jobs:
i) carries oxygen inside blood cells from the lungs to the muscles and organs that are working hard,
ii) Carries CO2 as bicarbonate, (waste) away from the hard working muscles and organs back to the lngs to be exhaled (breathed out)
iii) Carries heat away from hard working muscles, carries heat to cooler parts of the body
iv) Carries food to your organs
2) Your body needs more food, oxygen, heat removal and waste CO2 removal when you make it run around.
3) Your heart beats faster so it can move more blood to provide what your body needs.

Why does your heart beat faster when you work out or exercise?
When you exercise you breathe, and your heart beats faster so that it can pump more blood around you body to keep you moving. When you work out, you are moving/using all the muscles of your body. Muscles require oxygen and energy (calories) to continue to respond to your directions like walking or jogging or any other kind of activity. To ensure that the energy and oxygen reach all the necessary blood vessels, the heart would have to increase its pace. The more strenuous your workout, more would be the oxygen requirement and hence the brain would instruct the heart to beat faster to ensure that the muscles are not fatigued because of lack of oxygen. This is why your heart starts beating faster when you indulge in any form of physical activity. The more strenuous your activity, higher would be the heart beat rate.
