Does exercise increase our BPM?

Mr. Quaid’s class investigated how exercise affects their beats per minute (BPM). As part of the Marathon Kids programme children in Mr. Quaid’s class have been learning about how running can help you maintain a healthy lifestyle and keep your heart strong and healthy. Children identified where on their bodies they could best feel their pulse. Next, they measured the resting BPM. Then, they ran a distance of 800m and calculated their BPM again. They typed up and audio recorded their investigations on the ipads using the Keynote app. In groups, children created a bar chart on the iNumbers app to show each of their results. This helped to reveal any trends. They concluded that exercise does increase your BPM. Finally, they converted the Keynote presentation to a video.

Tooth Decay Investigation

Children developed a simple understanding of the structure and function of our mouth and teeth and how they help up receive nutrition. They explored how different liquids affect teeth and can cause tooth decay. Eggshells are made up of a similar material as the enamel of our teeth. As such we are using eggshells to investigate the affect of exposure to different liquids on our teeth. We concluded that water and milk are better for our teeth while fizzy drinks, orange juice and vinegar are the worst for our teeth. Children understood how oral hygiene and choosing the correct food and drink can help our body protect itself against disease and infection.
