It’s time for a heart-to-heart talk about blood and circulation with Bill Nye the Science Guy.

Scientific evidence suggests that sitting for long periods of time can cause health problems and that standing and moving around is better for us. But as with any scientific evidence, we need to ask questions about the evidence to determine if it can be trusted.

Humans and animals have a powerful bond. Some people think that this bond could have a positive effect on human health and behaviour. But what does the science say? Investigate the evidence for yourself.

A low pulse rate and fast recovery time after exercise can be indicators of good physical fitness. This investigation encourages students to develop their investigative skills by thinking carefully about the quality of the data they collect.

From your feet to your brain and all points in between, your heart has a tough job circulating blood all through your body.

Bill Nye the Science Guy is all pumped up about hearts.

You may have heard people say that your heart is a pump. Well, they weren’t kidding. Your heart pumps blood 24 hours a day, everyday.

Are you feeling fit and healthy? Check your heart rate while resting and after physical activity by making your own stethoscope.
